What me, read a manual?  
Before you begin, please make sure that you read the Safety Instructions on page 2 and Getting Started on  
®
page 4. One will help you keep safe, and the other will get you started using your new TAPCO Blend 16 mixer.  
Your new mixer is designed to be set up quickly and to operate easily. We know it’s often seen as a sign of  
weakness to read a manual, along with asking for directions when lost, or admitting that it was you who painted  
the dog purple and green when you were eight, ..er....but maybe you can read the rest of the manual when  
nobody is looking.  
Please keep your receipt in a safe sock drawer, and write your product information here for future reference  
(i.e., insurance claims, tech support, return authorization, etc.):

Getting Started  
The following steps will help you set up your mixer, and get the levels and adjustments just  
right. Please follow the instructions in the order they are presented, rather like following the  
instructions for mixing a lemon bundt cake, or running a nuclear power station, for example.  
ꢀ. Choose one of the microphones or instruments  
ZERO THE CONSOLE:  
1. Turn everything off, including the mixer’s rear panel  
connected to the mono MIC or INST inputs.  
ꢁ. Press that channel’s SOLO switch in.  
POWER switch and PHANTOM POWER switch.  
ꢂ. Have a wandering musician make some noise. If  
it’s a microphone connected to that channel, sing  
sweetly at the normal volume. If it’s a synthesizer,  
play it at its normal output level.  
ꢀ. Turn down all channel strip GAIN, AUX SEND 1, and  
AUX SEND 2 knobs.  
ꢁ. Center the channel strip EQ and PAN knobs.  
ꢂ. Turn down the MASTER FX RETURNs and AUX SENDs,

knob until the nearby LEVEL SET LED starts blinking.  
5. Move all FADERs fully down.  
6. With SOLO pushed in, you should see the meters  
grooving along with the music (and the RUDE  
SOLO light blinking).  
6. Center the Stereo Graphic EQ sliders.  
7. Make sure all push buttons are in the up position.  
7. If the GAIN is set correctly, the sound level should  
be nicely hovering around the 0 dB LEDs. If the  
average seems to be higher, turn down the GAIN.  
If it seems too low, turn it up.  
CONNECTIONS:  
1. Connect speakers to your amplifier’s outputs  
(unless you have powered speakers with built-in  
amplifiers).  
8. Carefully turn up the PHONES knob and listen.  
9. If necessary, apply channel EQ changes.  
10.Turn down the PHONES knob.  
ꢀ. Plug all the sound system components into suitable  
AC outlets, properly grounded and capable of  
delivering correct voltage and adequate current.  
11.Release the SOLO switch for that channel.  
ꢁ. Make connections from your mixer’s MAIN MIX  
1ꢀ. Repeat steps 2 through 11 for all other active  
channels, until all the GAINs are set correctly. You  
can repeat this procedure later, if needed. Once  
you get going, you will be surprised how quickly  
you can set up all the levels.  
outputs to your amplification system’s line inputs.  
ꢂ. Connect your microphones and instruments to the  
mixer: Connect microphones to the mono channel  
MIC jacks. (For condenser microphones, you may  
have to turn on the PHANTOM POWER switch,  
so read your Mic’s documentation.) Connect  
instruments directly to the INST 1/4" inputs, and line-  
level sources (synthesizers, guitar effects, preamps)  
to the stereo channel LINE IN 1/4" inputs.  
MAKING THE MIX:  
1. Make sure all levels are set correctly, as described in  
the previous section.  
ꢀ. Set the SOURCE SELECT switch to MAIN MIX, so your  
5. Connect the USB port to an open USB port on  
your computer, using the cable provided. Two  
channels of audio can be sent to your computer  
for recording, and two channels can return onto  
the main mix from your Tracktion or other DAW  
software. See “USB and the Blend 16” on page  
19, for more details about using the mixer with a  
computer.  
meters (and headphones) will receive the main mix.  
ꢁ. Add an active channel to the main mix by pressing  
the L-R switch near the bottom of that channel strip.  
ꢂ. Turn that channel’s FADER up to the U mark (0 dB).  
5. Carefully turn up the MAIN MIX FADER and listen to  
the glorious sounds in your main speakers.  
6. Repeat steps 3 and 4 until all active channels are  
added to the main mix. As you add each instrument,  
shout out its name loudly like this: “Introducing Billy-  
Bob Beauregarde-Baker on Big Bass Banjo.”  
6. Zero the console, as described above.  
7. Turn on your components’ power switches, leaving  
the amplifier (or powered speakers) until last.  
8. Now you are ready to set the levels.  
7. Carefully adjust the channel FADERs and the Graphic  
EQ to suit the main mix to your delicate audio senses.  
SET THE LEVELS:  
1. You can set the levels without hearing the sounds,  
but if you prefer, connect a set of headphones to  
the PHONES jack.  
8. To use the internal processor, adjust each channel’s  
AUX SEND 2 FX control to send signals to the  
processor. Adjust the FX INPUT LEVEL knob so the  
internal processor is not overloaded (FX OL LED off).  
Add the processed signal to the main mix using the  
FX RETURN TO MAIN MIX knob.

9. Now that you have a rough mix going, you  
may need to readjust the MAIN MIX FADER to a  
comfortable listening level. The meters should  
indicate by lighting most of the green LEDs when  
music is playing, and occasionally light the yellow.  
Only plug your amplifier’s speaker-level outputs  
into speakers, never to the mixer.  
Never use guitar cables to connect amplifiers to  
speakers.

amplifier, or reconfiguring an amp’s routing, turn  
the amp’s level (gain) controls down, turn the  
power off, make the changes, turn the power  
back on, and then turn the level controls back up.  
When you shut down your equipment, turn off any  
external amplifiers first. When powering up, turn on  
the amplifiers last.  
A FEW PRECAUTIONS:  
Never listen to loud music for prolonged  
periods. Please see the Safety Instructions  
on page 2 for information on hearing  
protection.  
Save the shipping box and packing material!  
The box can also be turned into a unique hat for  
attending Audio Society meetings, or stepping out  
in style.

Introduction  
Thank you for choosing a TAPCO Blend 16 mixer, with 16 channels of pure goodness. It has even more  
channels than an 8 channel mixer, and not quite as many as most 20 channel mixers.  
The TAPCO family of mixers hails back to the days of TAPCO Corporation, Greg Mackie’s first company.  
TAPCO revolutionized the audio industry back in 1969 with the very first 6-channel mixer designed for keyboards  
and rock ‘N’ roll PA. The first TAPCO mixer, although primitive by today’s standards, was truly innovative for its  
time. It had the headroom to handle screaming singers, was priced for the pocketbook of starving psychedelic  
musical neophytes, and durable enough to withstand mammoth levels of wear and tear on the road, and at  
now-legendary concerts.  
This compact mixer is perfect for small to medium-sized live sound reinforcement applications, keyboards  
and synths, video, and project studio applications.  
The USB port on the Blend 16 makes it easy to get audio from your mixer to your computer-based DAW. And  
just in case you don’t have the software, we’ve included a CD-ROM with the full version of Tracktion, our easy-  
to-use multitrack recording and sequencing software (for the PC or Mac). Refer to the installation instructions on  
the Blend 16 software CD to install Tracktion on your computer.

Blend 16 Features  
These 1/4" TRS inputs allow you to insert external  
processing equipment into the channel signal path  
(after the LOW CUT (6) switch and before the EQ).  
Using a special Insert plug, the mono signal can  
be sent out to a processor, and the processed signal  
returned, all on the same plug (see Appendix B).

MONO CHANNELS  
Mono channels 1 to 8 allow adjustment  
of EQ, Pan, and Level for mono signals. The

assigned to the main mix and subgroups.

If you haven’t already, please read “SET THE  
LEVELS” on page 4.  
This control allows you to adjust the input sensitivity

from the outside world to be adjusted to the correct  
level, not too strong to cause distortion and not too  
weak to be lost in noise.

The U symbol on most of the controls  
INST  
stands for “unity gain,” meaning there  
is no change in signal level. Once you  
have adjusted the GAIN control correctly,  
you can set every control at U, and your  
signals will travel through the mixer at  
optimal levels.  
Use the XLR inputs, or the 1/4" inputs,  
but not both on the same channel at the  
same time. Dedicate each mono channel  
to only one input at a time.

This handy LED lets you know that the signals  
going into the mixer are adjusted correctly.  
After you connect a microphone or line-level  
component to the mixer, do a sound test and  
adjust the GAIN (4) control until this LED flickers just  
occasionally. If it glows constantly, turn the GAIN (4)  
down. If the LED is doing almost nothing, turn it up.

1. MICROPHONE INPUTS  
Channels 1 to 8 each have a real butch  
and rugged, low-noise, phantom-powered  
microphone preamplifier, providing  
crystal-clear amplification. Their balanced  
circuitry rejects all manner of extraneous  
interference. Professional condenser,  
dynamic, and ribbon mics all sound  
excellent through these XLR inputs.  
You can plug in almost any kind of  
balanced mic that has a standard XLR-  
type male mic connector. See Appendix B  
for more information on XLR connectors.  
These XLR inputs can provide +48 VDC  
phantom powering on pins 2 and 3. This  
can be turned on and off using the rear  
panel PHANTOM POWER (54) switch.  
Caution: DO NOT connect  
6. LOW CUT FILTER SWITCH  
This inserts a low cut filter into the signal path,  
reducing the bass level (below 75 Hz, at 12 dB per  
octave, if specs are your thing). This occurs after  
the GAIN (4) level, but before the INSERT (3), EQ  
(7-10) and AUX (11-12) sections. Use this to cut  
down the low bass from things like stage rumble,  
mumble, bumble, and any low sounds that seem to  
come from two apartments down. We recommend  
you use this on all channels unless they have low  
frequency signals such as kick drums and bass  
guitars.

Although you can bring a sound to life with  
proper EQ, you can also mess things up. If you max

Turn this clockwise to boost the level of all  
frequencies above 12 kHz. Turn it counter-clockwise  
to cut the levels.  
Use this wisely to add sizzle to cymbals or an  
overall sense of transparency or edge to keyboards,  
vocals, guitar, and bacon frying. Turn it down a little  
to reduce sibilance or hide tape hiss.  
ꢀ. INST INPUTS  
The INST (instrument) inputs accept 1/4"  
TRS balanced and TS unbalanced plugs.  
These high-impedance inputs are  
suitable for the direct connection of  
instruments such as guitars, without the  
need for a direct box or guitar preamp.

8. MID FREQ EQ  
1ꢁ. PAN  
This adjusts the frequency of the MID EQ  
(9) control from 100 Hz to 8 kHz. This gives  
you great flexibility in shaping your sound.  
Listen carefully for its effect.  
This adjusts how much of the channel signal plays  
in the left side of the main mix and subgroups, and  
how much plays in the right. Careful use of PAN  
allows you to set up a nice stereo image in the left  
and right.  
MIC  
9. MID EQ  
For the mono channels, if PAN is in the center  
position, the mono signal appears equally in both  
the left and right of the main mix. If the control is set  
left, more of the signal appears in the left side. If the  
control is set right, more of the signal appears in the  
right side of the mix.  
Turn this clockwise to boost the level  
of signals around the frequency set by  
the MID FREQ (8) control. Turn it counter-  
clockwise to cut the levels.  
INST  
For stereo sources, where you are using two mono  
channels, the standard convention is to plug in the  
left signals into the odd-numbered channels, and  
the right signals into even-numbered channels. Then  
you can pan the odd channels hard left, and the  
even channels hard right.  
10. LOW EQ  
Turn this clockwise to boost the level of  
all frequencies below 80 Hz. Turn it counter-  
clockwise to cut the levels. Try some boost  
with the LOW CUT (6) switch on, so you  
can boost useful bass, at the same time as  
cutting unwanted subsonics.

it to the AUX 1 bus. The control ranges from  
infinity (off) to +15 dB.  
AUX SEND 1 MON is normally used to  
send a separate mono mix to your stage  
monitors, via the AUX SEND 1 (22) output  
jack. Use the MASTER AUX SEND 1 (43)  
knob to control the overall level.  
Most of the channel controls will affect  
the output to your stage monitors, except  
for PAN (13), AUX SEND 2 FX (12) and the

For example, if you want channel 1 to go to  
the subgroup 1-2, and subgroup 3-4, press the 1-2  
and 3-4 switches of channel 1. (The channel 1 PAN  
(13) knob will pan the channel’s signal between

17. FADER  
This is the master level control for the channel’s  
signal. Subtle adjustment of the channel faders is the  
key to a finely-tuned mix.  
Typically (providing the GAIN (4) is set correctly),  
this will be somewhere near the 0 dB (U) position.  
If you have the fader set all the way up, it’s usually  
a sign that your GAIN (4) is set too low. If the fader is  
set way down, your GAIN may be too high.

Suppose you have a turntable  
and a favorite record from when you  
were young. Connect the phono-  
level outputs of the turntable to the  
Ch 13 and 14 1/4" inputs. (You might  
need a pair of RCA to 1/4" adapters,  
depending on your turntable.) Also

Guitars and other instrument-level  
sources should not be connected  
directly to these inputs. Use the INST  
(2) inputs of channel 1 to 8, or use a  
preamp to give a line-level output,  
and connect that to these inputs.  
Mono sources should be  
connected to the left input only. The  
left signal will then be split equally to  
the left and right. You can use the  
PAN (13) control to change the left/

When connecting a mono device (just one cord),  
you’ll need a “Y-splitter” RCA adapter. It turns a  
mono output cord into two cords, so both the right  
and left tape input jacks can be used. This adapter  
is widely available. See Appendix B for more  
information about RCA connectors.  
ꢀꢀ. AUX 1 SEND MON OUTPUT  
To create a stage monitor mix, connect this  
1/4" TRS output to the input of your stage monitor  
amplifier (or powered monitors).  
Each channel’s AUX SEND 1 MON (11) knob  
adjusts how much of the channel’s signal appears  
on the AUX 1 bus. The AUX 1 bus carries the sum of  
all those active channels whose AUX SEND 1 MON  
(11) knobs are set to more than minimum position.  
The MASTER AUX SEND 1 (43) knob allows you  
to adjust the overall output level to your stage  
monitors.  
You can use the internal 7-band graphic EQ (31)  
to equalize the monitor mix, by pressing in the MAIN  
MIX/AUX 1 (MON) (32) switch.  
This output to your stage monitors is not affected  
by the channel FADERs (17) or MAIN MIX FADER (52).  
This is a good thing, as the monitors are not affected  
by level changes to your main mix.  
Caution: There is a chance of feedback  
if you have the tape inputs and outputs  
connected to the same recorder, and the  
recorder is in record mode.  
ꢀ6. CD/TAPE OUTPUTS  
Use these RCA jacks to capture the entire  
performance to tape. The output signal is a direct  
copy of the main mix, as it appears at the MAIN  
MIX (58) outputs and the USB (62) output to your  
computer.  
You could also use these outputs to connect  
to the unbalanced RCA inputs of a home stereo  
amplifier, if you had a mind to.  
ꢀꢁ. AUX ꢀ SEND FX OUTPUT  
Do not use long runs of unbalanced cables, or  
there might be signal degradation and noise. Try  
using good quality cables as sold in Hi-Fi stores.  
Use the tape player’s record-level control to set  
up the correct levels for recording. Take care if you  
use the MAIN MIX FADER (52) to adjust the levels, as  
this will affect your MAIN MIX (58) outputs as well as  
these Tape outputs.  
This 1/4" TRS output is intended to patch into an  
external effects processor, hence the name FX.  
Each channel’s AUX SEND 2 FX (12) knob adjusts  
how much of that channel’s signal appears on  
the AUX 2 bus. The AUX 2 bus carries the sum of all  
active channels whose AUX 2 SEND FX (12) knobs  
are set to more than minimum.  
The MASTER AUX SEND 2 (44) knob affects the final  
output level to your external processor.  
This output is affected by the channel FADERs  
(17), but not the MAIN MIX FADER (52).  
Note: Before the AUX 2 signals reach the MASTER  
AUX SEND 2 FX (44) knob, a copy is tapped off to go  
to the internal Effects processor, and from there onto  
the main mix bus.  
MASTER SECTION  
So far, we have described the channels, and how  
the signals from all of your microphones, instruments,  
line-level sources and CDs or Tapes get onto the  
main mix buses, subgroups 1 to 4, and the Aux  
buses. Now we come to the Master section, that  
controls what happens next.  
ꢀꢂ. FX RETURN INPUTS  
ꢀ7. POWER LED  
If you have an external effects processor, you can  
plug it into these inputs.  
This light glows when the mixer is turned on. If it is  
off, the mixer will sulk and not work. Check that the  
rear panel power switch is on, that the power cord  
is plugged in, and any power strips or wall switches  
are on. Also check if all the lights are out in your  
neighborhood. You never know.  
The incoming signals are added into the main mix,  
and a summed mono signal is added to the monitor  
mix. Adjustment is provided by the fascinating FX  
RETURN (45, 46) controls described in the Master  
section.  
When connecting a mono device (just one cord),  
always use the left (mono) input and plug nothing  
into the right input. The signal appears on both sides.

from the AUX 2 FX bus, and it outputs stereo signals  
onto the main mix buses. It also adds a summed  
mono signal to the stage monitor mix (AUX 1 bus).

noise, or use it to quickly compare between the  
effective effect of effects and the effect of no

Push SUBS 3-4 to hear subgroup 3 and 4 outputs.  
Note: If any channel has its SOLO (18) switch in, then  
only the SOLOed channels are heard in the control  
room or headphones.  
ꢁ8. USB OUTPUT: MAIN MIX/SUBS 1-ꢀ  
This switch allows you to choose if the main mix or  
if subgroups 1 and 2, are sent out of the mixer’s USB  
(62) output to your computer.  
If pressed in, the A/D converters of the USB  
section receive the output from subgroups 1 and 2  
(before the SUB FADERS (50)). This is a good position  
for studio recording and overdubbing with your  
computer.  
If pressed out, the A/D converters receive the  
main mix (after the MAIN MIX FADER (52)), just  
the same program as your main speakers and  
tape deck will receive. This is a good position  
for recording the main performance onto your  
computer.  
ꢂꢁ. AUX 1 (MON) MASTER SEND  
This knob is the master level control of the AUX  
SEND 1 MON (22) output jack. Adjust this knob to  
control the overall level of your stage monitor mix.  
ꢂꢂ. AUX ꢀ (FX) MASTER SEND  
This knob is the master level control of the AUX  
SEND 2 FX (23) output jack. Adjust this knob to  
control the level sent to your external processors.  
Further details of the USB connections and  
operation are described on page 19.  
ꢂ5. FX RETURN TO AUX 1 MON  
This knob allows you to adjust the level of the  
effects going onto the AUX 1 MON bus and out to  
your stage monitors.  
Signals (from external processors) coming into the  
AUX FX RETURN (24) jacks, and the internal effects  
processor output (unless bypassed), are summed to  
mono and added to the AUX 1 Monitor bus through  
this level control.  
ꢁ9. USB OUTPUT LEVEL and OL LED  
The USB section has an A/D converter that  
converts the selected analog channels into a digital  
stream.  
This knob allows you to adjust the signal level  
before it reaches the A/D converters. Turn it down If  
you see the OL light come on.  
The control ranges from minimum fully counter-  
clockwise, to unity gain at the center, to +15 dB fully  
clockwise.  
Like all OL overload LEDs, this is an important one  
to keep an eye on, so the outputs to your computer  
are not distorted.  
ꢂ6. FX RETURN TO MAIN MIX  
This knob allows you to adjust the level of effects  
going onto the main mix bus and out to your main  
speakers.  
Signals (from external processors) coming into the  
AUX FX RETURN (24) jacks, and the internal effects  
processor output (unless it is bypassed) are added to  
the main mix bus through this level control.  
The control ranges from minimum fully counter-  
clockwise, unity gain at the center, to +15 dB fully  
clockwise.  
ꢂ0. PHONES  
This adjusts the headphone levels without  
disturbing the main mix or control room levels.  
Turn this down before connecting and putting on  
your headphones, or before engaging any switches.  
Bring it up slowly.  
Caution: Be very careful because the  
PHONES (30) output can drive any  
standard headphones to very loud levels.  
Please see page 2 for information on  
hearing protection.  
ꢂ7. RUDE SOLO LED

This rather annoying light flashes on and off as  
a reminder when any of the channel SOLO (18)  
switches are pushed in. When flashing, you will hear  
the SOLOed channel(s) in the control room and  
headphones.  
This adjusts the output level to your control  
room, from the source selected using the SOURCE  
SELECT (42) switches below. It does not affect the  
headphones level or the main mix level.  
ꢂꢀ. SOURCE SELECT Switches  
Use these four switches to select the signal source  
for the control room outputs, headphones, and  
meters.  
ꢂ8. METERS  
These LEDS show the level of the control room and  
headphone signals, before the control room and  
headphones level controls.  
As the control room/phones source select  
switches are engaged, you can view the levels of  
the different sources (main mix, CD/Tape, Sub 1-2  
and Sub 3-4).  
The calibrations are: –24, –12, –4, 0, +4, +8, +12  
and +16 dB (Clip), where 0 dB = 0 dBu.  
Caution: Turn down the CTRL ROOM (41)  
and PHONES (40) knobs before pushing  
these switches.  
When the switches are up, the control room  
outputs, headphones, and meters receive no signals  
(unless any channels have SOLO (18) engaged).  
Push MAIN MIX to hear the main mix.  
You can get a good mix with the meter’s peaks  
flashing anywhere between –24 and +8 dB. Most  
Push CD/TAPE to hear your CD or Tape player.

amplifiers clip at about +10 dB, and some recorders  
aren’t so forgiving either. For best real-world results,  
try to keep your peaks between 0 dB and +8 dB.  
If your meters are too high, you will get distortion.  
If they are too low, then your signal-to-noise will  
suffer. Use the meters to help you adjust the mixer for  
optimum performance without distortion or noise.  
Then you can adjust your amplifier’s level controls for  
good overall volume.

Push the top of the switch labeled “ON” to turn  
the mixer on; you should see the POWER LED (27)  
glow with happiness. To turn the mixer off, push the  
bottom of the switch.  
58. MAIN OUTPUTS  
These 1/4" TRS jacks and XLR jacks represent the  
end of the mixer chain, where your fully mixed stereo  
signal entertains your audience.  
Connect these outputs to the inputs of your  
amplifiers, powered speakers, or serial effects  
processor (graphic equalizer, for example).  
As a rule, turn the mixer on first, before any amp  
or powered speakers. At the end of a show, turn it  
off last. This will prevent any turn-on/turn-off thumps  
from being heard in the speakers.  
5ꢂ. PHANTOM POWER  
59. MAIN INSERTS  
Turn on this switch to provide +48 VDC phantom  
power to the MIC (1) input XLR jacks (pins 2 and 3).  
Phantom power is required to operate most  
condenser microphones (some condenser  
microphones are battery-powered).  
These allow you to insert an external device such  
as the Tapco SQUEEZE compressor/limiter or TWEEQ  
graphic EQ into the main mix signal path.  
You will need “Insert Cables” that allow the main  
mix signals to go out to your external device, and  
have the processed signals come back into the  
mixer on the same plug (see Appendix B).  
The inserts are taken directly from the main mix  
bus, before the 7-Band EQ (31) and the MAIN MIX  
FADER (52).  
If you have ribbon mics, tube mics, or dynamic  
mics that do not require phantom power, leave the  
switch out. If you are using both condenser and  
dynamic mics, don’t worry. Phantom power will not  
hurt most dynamic mics. Check the microphone’s  
user manual if you’re not sure.  
Caution: Turn all output levels down

connecting or disconnecting your microphones.  
55. AC POWER IN  
This standard IEC connection is where you  
connect the supplied power cord.  
Connect the power supply cord to the Blend 16  
first, then plug the power supply into a suitable and  
properly rated AC outlet.  
The Blend 16 has a universal power supply that  
will operate with AC mains voltages from 100 VAC to  
240 VAC.  
61. SUBGROUP OUTS  
These 1/4" TRS jacks represent the output from  
your subgroups. You can connect them to amplifiers  
or powered speakers, or send the outputs off to an  
ADAT recorder (or not use them at all).  
6ꢀ. USB IN/OUT  
56. AC FUSE  
One end of the supplied USB cable connects  
here, and the other end connects to the USB port of  
your computer. The USB cable can simultaneously  
send and receive two channels of audio to and  
from any Mac or PC audio software.  
If you suspect a blown fuse, disconnect the power  
cord, pull the fuse drawer out (located just below  
the cord receptacle) and replace the fuse with  
the same type and current rating. If two fuses blow  
in a row, something is very wrong, and you should  
unplug the mixer and call technical support.

Appendix A: Using the Blend 16  
At first glance, the controls on the front panel of the  
Blend 16 may seem more at home in a space movie,  
right next to the Navigation officer. Like most things,  
it’s worse than that really. Here is a brief overview that  
may help you understand the basic functions and  
mysterious inner workings of the Blend 16.  
The FX RETURN input has a similar control to adjust  
the level of internal and external effects going on  
to the main mix.  
Channels 15 and 16 can switch the audio output  
from your computer’s software (such as Tracktion)  
onto the main mix.  
Channels 13 and 14 can accept the signals from a  
turntable onto the main mix.  
Buses  
A public transportation bus takes many passengers  
and delivers them to various destinations. In a similar  
way, an audio bus combines multiple audio signals  
and delivers them to an output.  
Auxiliary 1 Stage Monitor bus  
The Aux 1 Mon bus is normally used for sending  
an output to your stage monitors, so the band can  
clearly hear what they are playing, amidst the wild  
frenzy of the audience.  
The Blend 16 has two main mix buses, two auxiliary  
buses, and four subgroup buses.  
Main Mix Buses  
The audio signals from the microphones, guitars,  
instruments and keyboards of your wonder-band can  
be combined in the main mix bus and sent to your  
main amplifiers and speakers (or powered speakers).  
This could be your Club speaker system, or Uncle  
AUX 1 MONITOR BUS  
To get signals onto the Aux 1 Mon bus, rotate the  
AUX SEND 1 controls located just below the EQ section  
of each channel strip.  
The stage monitors receive a mix that is  
independent from the main mix, and not affected by  
the channel faders or Main Mix fader.  
MAIN MIX BUS LEFT  
MAIN MIX BUS RIGHT  
The mixer has a separate AUX SEND 1 output, that

Ernie’s garage.  
Auxiliary ꢀ Effects bus  
To get the channel signals onto the left and right  
main mix buses, press the L-R buttons near the bottom  
of each channel strip.  
The Aux 2 FX bus is normally used to send an output  
through the internal effects processor and onto the  
main mix, and to send an output to external effects  
via the AUX SEND 2 output.  
The channel PAN knobs adjust the signal balance  
onto the buses. Mono signals are shared equally to  
the left and right bus if the PAN is centered. With PAN  
fully left, the signals just go onto the left bus, and with  
PAN fully right, they go onto the right bus.  
Each channel can be tweaked in EQ and level,  
and the MAIN MIX FADER used to adjust the overall  
volume level. The main mix can also be assigned to  
the USB output, and sent to a computer for recording.  
AUX ꢀ EFFECTS BUS  
In addition to the channel inputs, the main mix can  
receive the following:  
To get signals onto the Aux 2 FX bus, rotate the AUX  
SEND 2 controls located just below the EQ section of  
each channel strip.  
Each of the four subgroups has an L and R switch  
to assign the output onto the main mix. See below  
for more subgroup details.  
Unlike Aux Send 1, the levels going to Aux Send 2  
are affected by the channel faders. (As the channel  
faders are changed, the signal levels going to the  
internal and external processors change.)  
The CD/Tape input has a level control to adjust the  
amount of signal going onto the main mix.

In a live situation, you can capture a recording of  
exactly what the audience heard to your computer’s  
hard drive, perhaps to burn a CD later.  
Configuration:  
Set up your mixer for your live show as you normally  
would. Be sure the USB SOURCE button is in the up  
position; your computer will receive a copy of the  
mixer’s stereo main mix signals.  
Adjust the USB Level Control so the USB OL  
LED does not light during the sound tests or  
performance, encores etc.  
Open your recording software of choice and  
begin recording the Blend 16 USB input. This can  
be done in either mono or stereo, depending on  
how you are mixing your live show (there’s no  
reason to record in stereo if you are mixing the  
show in mono).  
Be sure the USB button is not engaged on channels  
15-16 as this may cause a feedback loop with  
some DAW setups.  
To get subgroups onto the main mix, press the L  
and/or R buttons above each SUB FADER.  
Control Room and Phones Section  
The control room section lets you select and  
monitor the main mix, the CD/Tape player, subgroups  
and listen to individual SOLOed channels, all without  
interrupting the main mix. You can set up a separate  
amplifier and speakers for a studio control room,  
Uncle Ernie’s control shed, or headphones.  
Solo  
Any channels with their SOLO button engaged, will  
have their signals sent (pre fader) to the control room  
output and headphones for monitoring. This does not  
affect the main mix, so your band can still play on  
while you check individual channels and weed out  
Mr. Out-of-Tune from the boy band.  
Studio Recording and Overdubbing  
In your studio, you can record two channels  
or selected groups of channels to your computer,  
playback your recording, and perform overdubs by  
adding new material.  
USB and the Blend 16  
One of the cool features of the Blend 16 is its  
integrated USB input and output. Among other things,  
this allows you to record your live shows, perform  
recording sessions in your home studio, or use your  
computer as a jukebox/band member during live  
performances, with only your mixer, a computer and  
a USB cable. No extra computer audio interface  
hardware is needed.  
There are two different methods for monitoring the  
recording:  
Direct monitoring (listening to the direct sounds as  
you record).  
Software monitoring (listening through the  
recording software). For example, you might want  
to listen as you play your guitar through a new  
“warm amp tones” software simulator plug-in.  
Note: Use either monitoring method, but not both

2. Connect your amplifier/speaker system (or  
powered speakers) to the Control Room outputs,  
or connect headphones to the Phones output.  
Keep the Control Room and Phones level controls  
down for now. Press Main Mix in the Control Room  
source section, (you’ll be monitoring the main mix).  
3. Assign those channels you want to record to  
subgroups 1-2, but NOT to L-R main mix (i.e., press  
down the 1-2 switch on each channel, but leave  
each L-R switch up).  
4. Use PAN on each channel to select if the mics or  
instruments go to subgroup 1 or 2. For example, to  
record a vocal microphone and an electric guitar  
at once, route the mic to subgroup 1 (PAN fully left,  
and 1-2 down) and the guitar to subgroup 2 (PAN  
fully right, 1-2 down).  
Here is where Software Monitoring comes in:  
2. To listen through the software as you record,  
engage software monitoring in your DAW for the  
Blend 16 inputs. You will then be able to listen to  
the tracks while you are recording, including any  
software effects you might have added. This is  
done differently for each DAW, so consult your  
software’s manual if you are unsure how to do this.  
In Tracktion, you would enable “end to end” on  
the Blend 16 inputs.

Main aim:  
Use the computer as a sound source for playback  
during a live performance, or as the main sound  
source for their DJ set.  
Subgroup  
Subgroup 1-2  
USB  
Main Mix  
Laptop  
Faders  
Configuration:  
Setup your mixer for your live show as you normally  
would, but leaving channels 15-16 unused.  
Open your music software on your computer and  
configure it to output to the Blend 16.  
Press the USB button on channels 15-16. The  
output of your computer will now feed these  
channels.  
Using the channel 15-16 controls, route the  
incoming audio from your computer to the Auxes,  
Effects sends, subgroups, and/or Main L-R as  
needed, just as you would any other channel.  
If you would also like to record your show, you  
can send your main mix back to your computer  
for recording. Be sure software monitoring is NOT  
enabled in your DAW or you might get a feedback  
loop and could damage your ears and speakers.  
8. To perform an overdub and hear some previously  
recorded material (such as a drum beat) to play  
along to while recording, press the USB button on  
channels 15-16 and assign 15-16 to the main mix.

Hard Drive Notes  
To record a one minute 24-bit/44.1 kHz mono track  
requires approximately 8 MB of hard drive space.  
Preferably, use a second drive for recording audio,  
not your main drive with the operating system.  
It is best if you can start with a freshly de-  
fragmented drive before recording.  
Backup your files and de-fragment your drive  
often.  
Did we mention backing up your files often?  
We do not want you to be sitting back relaxing in  
the pub after a long day's recording session of your  
finest work, when all along there is a doubt in the  
back of your mind about having backed up your  
files.

Appendix D: Service Information  
No Audio into your Computer:  
Warranty Service  
Confirm the mixer is receiving mic or instrument  
input signals.  
Details concerning Warranty Service are spelled  
out in the Warranty section on page 27.  
If you think your TAPCO Blend 16 has a problem,  
please do everything you can to confirm it before  
calling for service. Doing so might save you from  
the deprivation of your mixer and the associated  
suffering.  
Make sure you have selected the right driver in  
your DAW. In Tracktion, this is in the Settings menu.  
If the mixer seems fine, click Restart Device in the  
Tracktion Settings menu.  
In Tracktion, be sure the correct inputs are selected  
and the tracks are armed.  
Here are some things you can check:  
Troubleshooting  
Echo or phasing from input while  
recording:  
Bad Channel  
Is the channel GAIN turned up?  
It sounds like you are monitoring both through  
software and directly. You should only do one or  
the other. See page 19 to help you decide which is  
best for your situation.  
Is the channel FADER turned up?  
Try the same source signal in another channel, set  
up exactly like the suspect channel.  
If you are overdubbing (or recording a new track  
alongside other tracks already recorded), try  
disabling your new track’s output to the mixer and  
monitoring the signal you are recording directly.  
Adjust the channel 15-16 fader and the subgroup  
1-2 faders so you can hear both your new input  
signal as well as the playback from the computer.  
If your microphone requires phantom power, make  
sure you engage the Phantom Power button  
(48V) on the rear panel of the mixer. Confirm the  
need to use phantom power by reading your  
microphone's documentation.  
Bad Output  
Is the MAIN MIX FADER at minimum perchance?  
Glitchy/Distorted Playback from  
Computer:  
If it’s a stereo pair, try switching them around. For  
example, if a left output is presumed dead, switch  
the left and right cords, at the mixer end. If the left  
speaker is still dead, it’s not the mixer. Perhaps it’s a  
bad cable, speaker, or amplifier channel.  
Increase the Buffer Size/Latency Setting:  
Tracktion (PC): choose the Settings Tab and Audio  
Devices. Click the “show ASIO control panel”  
button and try a larger buffer size.  
Noise  
Tracktion (Mac): choose the Settings Tab and  
Audio Devices and increase the Latency slider.  
Turn down the channel FADER, and AUX SEND  
controls, one by one. If the noise disappears, it’s  
either that channel or whatever is plugged into it,  
so unplug whatever that is.  
In other applications, find the control panel to  
increase the ASIO (PC) or Core Audio (Mac) buffer  
size or latency.  
Be sure the mixer is the only device on the USB  
chain. The easiest way to do this is to be sure the  
mixer is connected directly to your computer’s USB  
port; we do not recommend using USB Hubs.  
Power  
Our favorite question: Is the POWER switch on?  
Is the power cord securely plugged in  
?
Is the power supply cord securely plugged into  
an AC power strip? Make sure the power to the  
power strip is turned on.  
Try a song with fewer tracks, effects, and virtual  
instruments. If it plays fine, then you may be  
pushing your computer above its limits. Try  
increasing your latency settings as described  
above.  
If you suspect a blown fuse, disconnect the power  
cord, pull the fuse drawer out (located just below  
the cord receptacle) and replace the fuse with  
the same type and current rating. If two fuses blow  
in a row, something is very wrong, and you should  
contact technical support.  
Large latency (delay) from input  
signal to output:  
Change the latency/buffer setting to a lower  
setting, as described above.  
Are all the lights out in your building?  
Try using direct monitoring instead of software  
monitoring. See page 19 for details.

No Communication with the mixer:  
Repair  
The PC driver may not be installed correctly.  
Make sure your computer meets the system  
requirements. Uninstall the driver from the Add/  
Remove Programs control panel, restart your  
computer, and reinstall the driver.  
Service for Tapco products is available at a  
factory-authorized service center. Service for Tapco  
products living outside the United States can be  
obtained through local dealers or distributors.  
If your unit needs service, follow these instructions:  
1. Review the preceding troubleshooting suggestions.  
Please.  
Restart your computer and the mixer.  
2. Call Tech Support at 1-877-827-2669, 7 am to 5 pm  
PST, to explain the problem and request a Service  
Request Number. Have your serial number ready.  
You must have an Service Request Number before  
you can obtain warranty service.  
I hear my Windows/Mac sounds  
through my mixer, but I don’t want to:  
The mixer should not be selected as your computer’s  
sound system default device. To disable it:  
On a PC, go to Control Panel>Sound and Audio  
Devices. In the Audio tab, be sure the Blend 16  
is not selected as the default device for sound  
playback.  
3. Keep this owner’s manual and the detachable  
linecord. We don’t need them to repair the unit.  
4. Pack the unit in its original package, including  
endcaps and box. This is VERY IMPORTANT. Tapco  
is not responsible for any damage that occurs due  
to non-factory packaging.  
On a Mac, go to Applications>Utilities>Audio  
MIDI Setup. In the Audio Devices tab, be sure the  
Blend 16 is not selected for your default or system  
outputs. You can also change this in the Sounds  
Preferences pane of the OS X System Preferences  
application.  
5. Include a legible note stating your name, shipping  
address (no P.O. boxes), daytime phone number,  
Service Request Number, a copy of your sales  
receipt, and a detailed description of the problem,  
including how we can duplicate it.  
My guitar (or other instrument)  
doesn’t sound as good as I expect:  
6. Write the Service Request Number in BIG PRINT on  
top of the box. Units sent without the SR number  
will be refused.  
If your guitar is connected directly to the mixer  
(i.e., without a direct box or preamp), be sure you  
are using the INST input on channels 1-8.  
7. Tech Support will tell you where to ship the unit  
for repair. We suggest insurance for all forms of  
cartage.  
Check the mixer Gain and EQ settings, and make  
sure you have not overdone the EQ or the audio is  
clipping.  
8. You will need to contact the authorized service  
center for their latest turn-around times. The unit  
should be packaged in its original packing box,  
and must have the Service Request Number on  
the box. Once it’s repaired, the authorized service  
center will ship it back by ground shipping, pre-  
paid (if it was a warranty repair).  
Could we suggest you might need more practice?  
Can I transfer my classic record  
collection?  
Yes, but please follow all copyright rules.  
Mixer channels 13 and 14 can accept phono  
level signals from a turntable. The internal phono  
preamp equalizes and boosts your turntable  
phono-level signals to line-level.  
Note: Under the terms of the warranty, you must  
ship or drop-off the unit to an authorized service  
center. The return ground shipment is covered for  
those units deemed by us to be under warranty.  
It is most likely that your turntable has RCA  
outputs, so you will need to buy adapters from  
RCA (female) to 1/4" (male). These adapters are  
commonly stocked in most electronics and audio  
stores.  
Note: You must have a sales receipt from  
an authorized Tapco dealer for your unit to be  
considered for warranty repair.  
Lonely? Looking for that special  
someone? Do you have a question  
about your TAPCO Mixer?  
Some companies provide software plug-ins that  
remove pops and clicks from the recordings. This  
kind of spoils some of the fun though.  
Please call our Technical Support chaps at 1-877-  
8ꢀ7-ꢀ669, Monday to Friday, from 7 am to 5 pm PST.  
Contact Us, or e-mail us at [email protected]  
Still having USB problems?  
Be sure you are running the latest drivers.  
If after updating, you still are having problems,  
please call tech support.
