Important Safety Instructions  
1. Introduction  
The microphone channels feature high-end XENYX Mic  
Preamps that compare well with costly outboard preamps  
in terms of sound quality and dynamics and boast the  
following features:  
!
CAUTION!  
[6] Clean only with dry cloth.  
We should like to draw your attention to the fact that  
extreme volumes may damage your hearing and/or  
your headphones or loudspeakers. Turn the MAIN MIX  
faders and phones control in the main section fully  
[7] Do not block any ventilation openings. Install in accordance  
with the manufacturer’s instructions.  
[8] Do not install near any heat sources such as radiators, heat  
registers, stoves, or other apparatus (including amplifiers) that  
produce heat.  
130 dB dynamic range for an incredible amount of  
headroom  
down before you switch on the unit. Always be careful  
to set the appropriate volume.  
A bandwidth ranging from below 10 Hz to over 200 kHz  
for crystal-clear reproduction of even the finest nuances  
[9] Do not defeat the safety purpose of the polarized or grounding-  
type plug. A polarized plug has two blades with one wider  
than the other. A grounding-type plug has two blades and  
a third grounding prong. The wide blade or the third prong  
are provided for your safety. If the provided plug does not fit  
into your outlet, consult an electrician for replacement of the  
obsolete outlet.

1.1 General mixing console functions  
A mixing console fulfils three main functions:  
Terminals marked with this symbol carry electrical current of  
sufficient magnitude to constitute risk of electric shock. Use only  
high-quality commercially-available speaker cables with ¼" TS  
plugs pre-installed. All other installation or modification should be  
performed only by qualified personnel.  
The extremely low-noise and distortion-free circuitry  
guarantees absolutely natural and transparent signal  
reproduction  
Signal processing: Preamplification, level adjustment,  
mixing of effects, frequency equalization.  
They are perfectly matched to every conceivable  
microphone with up to 60 dB gain and +48 volt phantom  
power supply  
Signal distribution: Summing of signals to the  
aux sends for effects processing and monitor mix,  
distribution to one or several recording tracks, power  
amp(s), control room and 2-track outputs.  
[10] Protect the power cord from being walked on or pinched  
particularly at plugs, convenience receptacles, and the point  
where they exit from the apparatus.  
They enable you to use the greatly extended dynamic  
range of your 24-bit/192 kHz HD recorder to the full,  
thereby maintaining optimal audio quality  
*
This symbol, wherever it appears, alerts you to the presence of  
uninsulated dangerous voltage inside the enclosure - voltage that  
may be sufficient to constitute a risk of shock.  
Mix: Setting the volume level, frequency distribution  
and positioning of the individual signals in the stereo  
field, level control of the total mix to match the recording  
devices/crossover/power amplifier(s). All other mixer  
functions can be included in this main function.  
[11] Use only attachments/accessories specified by  
the manufacturer.  
“British EQ”  
[12] Use only with the cart, stand, tripod, bracket,  
or table specified by the manufacturer, or  
sold with the apparatus. When a cart is used,  
use caution when moving the cart/apparatus  
combination to avoid injury from tip-over.  
The equalizers used for the XENYX Series are based on  
the legendary circuitry of top-notch consoles made in  
Britain, which are renowned throughout the world for their  
incredibly warm and musical sound character. Even with  
extreme gain settings these equalizers ensure outstanding  
audio properties.  
!
The interface of BEHRINGER mixing consoles is optimized  
for these tasks enabling you to easily keep track of the  
signal path.  
This symbol, wherever it appears, alerts you to important operating  
and maintenance instructions in the accompanying literature.  
Please read the manual.  
[13] Unplug this apparatus during lightning  
storms or when unused for long periods of time.  
1.2 The users manual  
Multi-effects processor  
[14] Refer all servicing to qualified service personnel. Servicing is  
required when the apparatus has been damaged in any way,  
such as power supply cord or plug is damaged, liquid has been  
spilled or objects have fallen into the apparatus, the apparatus  
has been exposed to rain or moisture, does not operate  
normally, or has been dropped.  
The user’s manual is designed to give you both an overview  
of the controls, as well as detailed information on how to use  
them. In order to help you understand the links between  
the controls, we have arranged them in groups according  
to their function. If you need to know more about specific  
where you’ll find explanations of e.g. effects and  
Additionally, your XENYX mixing console has an effects  
processor with 24-bit A/D and D/A converters included,  
which gives you 100 presets producing first-class reverb,  
delay and modulation effects plus numerous multi-effects in  
excellent audio quality.  
!
Caution  
To reduce the risk of electric shock, do not remove the top cover  
(or the rear section). No user serviceable parts inside. Refer servicing  
to qualified personnel.  
The XENYX mixing consoles are equipped with a state-  
of-the-art switched-mode power supply (SMPS). Unlike  
conventional circuitry an SMPS provides an optimum supply  
current regardless of the input voltage. And thanks to its  
considerably higher efficiency a switched-mode power  
supply uses less energy than conventional power supplies.  
[15] The apparatus shall be connected to a MAINS socket outlet  
!
Caution  
dynamics applications.  
with a protective earthing connection.  
To reduce the risk of fire or electric shock, do not expose this  
appliance to rain and moisture. The apparatus shall not be exposed  
to dripping or splashing liquids and no objects filled with liquids,  
such as vases, shall be placed on the apparatus.  
The block diagram supplied with the mixing console  
gives you an overview of the connections between the  
inputs and outputs, as well as the associated switches  
and controls.  
[16] Where the MAINS plug or an appliance coupler is used as the  
disconnect device, the disconnect device shall remain  
readily operable.  
USB/Audio interface  
For the moment, just try and trace the signal path from the  
microphone input to the aux send 1 connector. Don’t be  
put off by the huge range of possibilities; it’s easier than you  
think! If you look at the overview of the controls at the same  
time, you’ll be able to quickly familiarize yourself with your  
mixing console and you’ll soon be making the most of all its  
many possibilities.  
The USB interface supplied with the unit is a perfect  
match for the XENYX Series and serves as a powerful  
recording interface to your PC or MAC. It supports the  
digital transmission of signals on up to four channels with  
max. 48 kHz and extremely low latency. When wired to  
the CD/TAPE INPUT and OUTPUT connectors, the interface  
transfers the stereo mix from the console directly to a  
computer. Both the recording signal and the playback signal  
from the computer can be monitored at the same time.  
In this way, you can use several recording runs to produce  
complete multi-track recordings.

1.3 Before you get started  
2.1.2 Equalizer  
If you press the MUTE/ALT 3-4 switch, aux send 1  
is muted, provided that it is switched post-fader.  
However, this does not affect the aux send 2 of  
the 1204FX.  
2. Control Elements and  
All mono input channels include a 3-band equalizer. All  
bands provide boost or cut of up to 15 dB. In the central  
position, the equalizer is inactive.  
1.3.1 Shipment  
Connectors  
Your mixing console was carefully packed in the factory to  
guarantee safe transport. Nevertheless, we recommend  
that you carefully examine the packaging and its contents  
for any signs of physical damage, which may have occurred  
during transit.  
This chapter describes the various control elements of your  
mixing console. All controls, switches and connectors will be  
discussed in detail.  
The circuitry of the British EQs is based on the technology  
used in the best-known top-of-the-line consoles and  
providing a warm sound without any unwanted side effects.  
The result are extremely musical equalizers which, unlike  
simple equalizers, cause no side effects such as phase  
shifting or bandwidth limitation, even with extreme gain  
settings of 15 dB.  
AUX 1 (MON)  
In the 1204FX, aux send 1 can be switched pre-fader and is  
thus particularly suitable for setting up monitor mixes. In the  
1204, the first aux send is labeled MON and is permanently  
switched pre-fader.  
2.1 Mono channels  
If the unit is damaged, please do NOT return it to us,  
but notify your dealer and the shipping company  
immediately, otherwise claims for damage or  
replacement may not be granted.  
2.1.1 Microphone and line inputs  
PRE  
When the PRE switch is pressed, aux send 1 is sourced  
pre-fader.  
1.3.2 Initial operation  
AUX 2 (FX)  
Be sure that there is enough space around the unit for  
cooling purposes and to avoid over-heating please do not  
place your mixing console on high-temperature devices  
such as radiators or power amps. The console is connected  
to the mains via the supplied cable. The console meets  
the required safety standards. Blown fuses must only be  
replaced by fuses of the same type and rating.  
The aux send labeled FX is for sending to effects devices and  
is thus set up to be post-fader.  
In the 1204FX, the FX send is routed directly to the built-in  
effects processor.  
If you wish to use the internal effects processor, the  
STEREO AUX RETURN 2 connectors should not be  
in use.  
Fig. 2.2: The equalizer of the input channels  
Please note that all units must be properly grounded.  
For your own safety, you should never remove any  
ground connectors from electrical devices or power  
cables, or render them inoperative.  
The upper (HI) and the lower band (LO) are shelving filters  
that increase or decrease all frequencies above or below  
their cut-off frequency. The cut-off frequencies of the upper  
and lower band are 12 kHz and 80 Hz respectively. The mid  
band is configured as a peak filter with a center frequency  
of 2.5 kHz.  
Fig. 2.1: Connectors and controls of mic/line inputs  
1204FX: you can also connect an external effects  
processor to aux send 2, however the internal effects  
module will be muted.  
MIC  
Please ensure that only qualified people install and  
operate the mixing console. During installation and  
operation, the user must have sufficient electrical  
contact to earth, otherwise electrostatic discharges  
might affect the operation of the unit.  
Each mono input channel offers a balanced microphone input  
via the XLR connector and also features switchable +48V  
phantom power supply for condenser microphones.The  
XENYX preamps provide undistorted and noise-free gain as is  
typically known only from costly outboard preamps.  
2.1.4 Routing switch, solo and channel fader  
2.1.3 Aux sends  
1.3.3 Online registration  
Please mute your playback system before you activate  
the phantom power supply to prevent switch-on  
thumps being directed to your loudspeakers. Please  
also note the instructions in chapter 2.4.2Voltage  
supply, phantom power and fuse.  
Please do remember to register your new  
BEHRINGER equipment right after your purchase  
conditions of our warranty carefully.

Should your BEHRINGER product malfunction, our goal  
is to have it repaired as quickly as possible. To arrange for  
warranty service, please contact the retailer from whom the  
equipment was purchased. Should your BEHRINGER dealer  
not be located in your vicinity, you may directly contact  
one of our subsidiaries. Corresponding contact information  
is included in the original equipment packaging (Global  
Contact Information/European Contact Information). Should  
your country not be listed, please contact the distributor  
nearest you. A list of distributors can be found in the support  
area of our website (www.behringer.com).  
Aux sends take signals via a control from one or more  
channels and sum these signals to a so-called bus. This bus  
signal is sent to an aux send connector and then routed,  
for example, to an active monitor speaker or an external  
effects device. The return from an external effect can then be  
brought back into the console via the aux return connectors.  
Each mono input also features a balanced line input on a  
¼" connector. Unbalanced devices (mono jacks) can also be  
connected to these inputs.  
Please remember that you can only use either the  
microphone or the line input of a channel at any one  
time. You can never use both simultaneously!  
For situations which require effects processing, the aux  
sends are usually switched post-fader so that the effects  
volume in a channel corresponds to the position of the  
channel fader. If this were not the case, the effects signal  
of the channel would remain audible even when the fader  
is turned to zero. When setting up a monitor mix, the aux  
sends are generally switched to pre-fader; i.e. they operate  
independently of the position of the channel fader.  
LOW CUT  
Fig. 2.4: Panorama and routing controls  
The mono channels of the mixing consoles have a  
high-slope LOW CUT filter for eliminating unwanted,  
low-frequency signal components (75 Hz, 18 dB/octave).  
PAN  
Registering your purchase and equipment with us helps us  
process your repair claims quicker and more efficiently.  
The PAN control determines the position of the channel  
signal within the stereo image. This control features a  
constant-power characteristic, which means the signal  
is always maintained at a constant level, irrespective of  
position in the stereo panorama.  
GAIN  
Thank you for your cooperation!  
Use the GAIN control to adjust the input gain. This control  
should always be turned fully counterclockwise whenever  
you connect or disconnect a signal source to one of  
the inputs.  
Both aux sends are mono, are sourced after the equalizer  
and offer up to +15 dB gain.

MUTE/ALT 3-4  
of a stereo signal is needed. There is often a discrepancy  
between the settings of the left and the right channels when  
using separate equalizers.  
If you want to monitor the signal of just one AUX bus,  
none of the other SOLO SWITCHES should be pressed  
and the MODE switch must be in the SOLO position  
(not pressed down).  
In this instance, the FX control of the channel being  
used as an effects return should be turned fully  
counterclockwise, otherwise feedback problems  
could occur!  
You can use the MUTE/ALT 3-4 switch to divert the channel  
from the main mix bus to the Alt 3-4 bus. This mutes the  
channel from the main mix.  
2.2.3 Aux sends stereo channels  
If you wish to use the internal effects processor, no  
connectors should be plugged into STEREO AUX  
RETURN 2.  
MUTE-LED  
2.3.2 Aux send connectors 1 and 2  
In principle, the aux sends of the stereo channels function  
in just the same way as those of the mono channels. As aux  
send paths are always mono, the signal on a stereo channel  
is first summed to mono before it reaches the aux bus.  
The MUTE LED indicates that the relevant channel is diverted  
to the submix (Alt 3-4 bus).  
2.3.4 Stereo aux return  
CLIP-LED  
The CLIP LED lights up when the input signal is driven  
too high. In this case, turn down the GAIN control and, if  
necessary, check the setting of the channel EQ.  
2.2.4 Routing switch, solo and channel fader  
BAL  
Fig. 2.7: Aux send connectors  
The function of the BAL(ANCE) control corresponds to the  
PAN control in the mono channels.  
SOLO  
AUX SEND 1  
The SOLO switch (1204FX only) is used to route the channel  
signal to the solo bus (Solo In Place) or to the PFL bus (Pre  
Fader Listen). This enables you to monitor a channel signal  
without affecting the main output signal. The signal you hear  
is sourced either before (PFL, mono) or after (solo, stereo)  
both the pan control and the channel fader (see chapter  
2.3.6Level meters and monitoring”).  
The balance control determines the relative proportion  
between the left and right input signals before both signals  
are routed to the main stereo mix bus.  
If you use aux send 1 pre-fader, you would usually connect  
the AUX SEND 1 connector to monitors via a power amp (or  
an active monitor system). If you use aux send 1 post-fader,  
proceed as described under aux send 2.  
Fig. 2.9: Stereo aux return controls  
The MUTE/ALT 3-4 switch, the MUTE-LED, the CLIP-LED, the  
SOLO switch and the channel fader function in the same way  
as the mono channels.  
STEREO AUX RETURN 1  
STEREO AUX RETURN 1 is a stereo control which determines  
the level of the signal in the main mix. If STEREO AUX  
RETURN 1 is used as effects return, you can add the effects  
signal to anydrychannel signal.  
AUX SEND 2  
The AUX SEND 2 connector outputs the signal you picked  
up from the individual channels using the FX control. You  
can connect this to the input of an effects device in order to  
process the FX bus signal. Once an effects mix is created, the  
processed signal can then be routed from the effects device  
output back into the STEREO AUX RETURN connectors.  
The channel fader determines the level of the channel signal  
in the main mix (or submix).  
2.3 Connector panel and main section  
Whereas it was useful to trace the signal flow from top to  
bottom in order to gain an understanding of the channel  
strips, we now look at the mixing console from left to right.  
The signals are, so to speak, collected from the same point  
on each of the channel strips and then routed to the main  
section all together.  
In this instance, the effects device should be set at  
100% effect.  
2.2 Stereo channels  
STEREO AUX RETURN MON  
2.2.1 Channel inputs  
The STEREO AUX RETURN MON control has a special function:  
it can be used to add an effect to a monitor mix.  
For example:  
2.3.3 Stereo aux return connectors  
2.3.1 Aux sends 1 and 2  
Monitor mix with effect  
In this instance, the effects device should be set up as  
follows: AUX SEND 2 is connected to the L/Mono input  
of your effects device, while its outputs are connected  
to STEREO AUX RETURN 1. Connect the amplifier of your  
monitor system to AUX SEND 1. The AUX SEND 1 master  
control determines the volume of the monitor mix.  
Fig. 2.5: Stereo channel inputs and LEVEL switch  
Fig. 2.8: Stereo aux return connectors  
Each stereo channel has two balanced line level inputs on  
¼" connectors for left and right channels. If only the  
connector markedLis used, the channel operates in  
mono. Stereo channels are designed to handle typical line  
level signals.  
Fig. 2.6: AUX SEND controls of the main section  
STEREO AUX RETURN 1  
You can now use the STEREO AUX RETURN MON control  
to adjust the level of the effects signal routed to the  
monitor mix.  
A channel signal is routed to aux send bus 1 if the AUX 1  
control is turned up on the corresponding channel.  
The STEREO AUX RETURN 1 connectors generally serve as the  
return path for the effects mix generated using the post-  
fader aux send. This is where you connect the output signal  
of the external effects device. If only the left connector is  
used, the AUX RETURN automatically operates in mono.  
You can easily use the headphones distribution amplifier  
BEHRINGER POWERPLAY PRO HA4600/HA4700/HA8000  
to provide you with four (or eight with the HA8000) stereo  
headphone mixes for your studio.  
Both inputs can also be used with unbalanced jacks.  
AUX SEND 1 (MON)  
LEVEL  
The AUX SEND control MON acts as master control for aux  
send 1 and determines the level of the summed signal. In the  
1204FX, the MON control is called AUX SEND 1.  
For level matching, the stereo inputs feature a LEVEL switch  
which selects between +4 dBu and -10 dBV. At -10 dBV  
(home-recording level), the input is more sensitive than at  
+4 dBu (studio level).  
You can also use these connectors as additional  
line inputs.  
STEREO AUX RETURN 2 (FX)  
AUX SEND 2 (FX)  
STEREO AUX RETURN 2  
The STEREO AUX RETURN 2 control determines the level of  
signals fed into the AUX RETURN 2 connectors which are  
routed to the main mix.  
Similarly, the FX control (AUX SEND 2) determines the level  
for aux send 2.  
The STEREO AUX RETURN 2 connectors serve as the return  
path for the effects mix generated using the FX control.  
If these connectors already function as additional inputs,  
you can route the effects signal back into the console via a  
different channel, with the added benefit that the channel  
EQ can be used to adjust the frequency response of the  
effects return signal.  
2.2.2 Equalizer stereo channels  
The equalizer of the stereo channels is, of course, stereo. The  
filter characteristics and crossover frequencies are the same  
as those of the mono channels. A stereo equalizer is always  
preferable to two mono equalizers if frequency correction  
SOLO  
MAIN MIX/ALT 3-4  
You can use the SOLO switch (1204FX only) to separately  
monitor the aux sends via the CONTROL ROOM/PHONES  
outputs and check these with the level meters.  
The MAIN MIX/ALT 3-4 switch routes the signal connected to  
STEREO AUX RETURN 2 to either main mix (not pressed) or  
submix (Alt 3-4, pressed).

MAIN MIX  
MODE (1204FX only)  
PHONES  
The MAIN MIX switch sends the main mix signal to the  
above-mentioned outputs and to the level meter.  
The MODE switch determines whether the channelsSOLO  
switch operates as PFL (Pre Fader Listen) or as solo (Solo  
In Place).  
You can connect headphones to this ¼" TRS connector. The  
signal on the PHONES connection is sourced from the control  
room output.  
PHONES/CTRL R(oom)  
PFL  
Use this control to set control room output level and head-  
phones volume respectively.  
2.3.7 Alt 3-4 and main mix fader  
To activate the PFL function, depress the MODE switch.  
The PFL function should, as a rule, be used for gain setting  
purposes. The signal is sourced pre-fader and assigned to the  
mono PFL bus. In thePFLsetting, only the left side of the  
peak meter operates. Drive the individual channels to the  
0 dB mark of the VU meter.  
CD/TAPE TO MAIN  
Fig. 2.10: 2-track connectors  
When the CD/TAPE TO MAIN switch is depressed, the 2-track  
input is routed to the main mix and thus serves as an  
additional input for tape machines. You can also connect  
MIDI instruments or other signal sources here that do not  
require any further processing. At the same time, this switch  
disables the main mix to tape output link.  
CD/TAPE INPUT  
The CD/TAPE INPUT RCA connectors are provided for  
connecting a 2 track machine (e.g. DAT recorder). They can  
also be used as stereo line input. Alternatively, the output  
signal of a second XENYX or BEHRINGER ULTRALINK PRO  
Solo  
When the MODE switch is not depressed, the stereo solo bus  
is active. Solo is short forSolo In Place. This is the customary  
method for listening to an individual signal or to a group of  
signals. As soon as a solo switch is pressed, all channels in the  
control room (and headphones) that have not been selected  
are muted thereby retaining stereo panning. The solo bus  
can carry the output signals of the channel pan controls, the  
aux sends and the stereo line inputs. The solo bus is, as a rule,  
switched post-fader.  
MX882 can also be connected. If you connect a hi-fi amplifier POWER  
with a source selection switch to the CD/TAPE INPUT, you  
can easily switch between additional sources (e.g. cassette  
recorder, CD player, etc.).  
The blue POWER LED indicates that the device is switched on.  
+48 V  
The red+48 VLED lights up when the phantom power  
supply is switched on. The phantom power supply is  
necessary for condenser microphones and is activated using  
the switch on the rear of the device.  
CD/TAPE OUTPUT  
These connectors are wired in parallel with the MAIN OUT  
and carry the main mix signal (unbalanced). Connect the  
CD/TAPE OUTPUT to the inputs of your recording device.  
The final output level can be adjusted via the high-precision  
MAIN MIX fader.  
Fig. 2.13: Alt 3-4 and main mix fader  
The PAN control in the channel strip offers a constant  
power characteristic. This means that the signal is  
always at a constant level, irrespective of its position in  
the stereo panorama. If the PAN control is moved fully  
left or right from center, the level increases by 4 dB in  
that channel. This ensures that, when set in the center,  
the audio signal is not louder. For this reason, with the  
solo function activated (Solo in Place), audio signals  
from the channels with PAN controls that have not  
been moved fully to the left or right are displayed at a  
lower volume than in the PFL function.  
Please do not connect microphones to the mixer (or  
the stagebox/wallbox) while the phantom power  
supply is switched on. Connect micro-phones before  
you switch on the power supply. In addition, the  
monitor/PA loudspeakers should be muted before you  
activate the phantom power supply. After switching  
on, wait approx. one minute to allow for system  
stabilization.  
Use the high-precision quality faders to control the output  
level of the Alt 3-4 subgroup and main mix.  
If you connect a compressor or a noise gate after the  
2-track output, the faders will probably not be able to  
create a satisfactory fade-out effect.  
2.4 Rear view of 1204FX/1204  
2.4.1 Main mix outputs, Alt 3-4 outputs and  
control room outputs  
2.3.6 Level meter and monitoring  
LEVEL METER  
The high-precision level meter accurately displays the  
appropriate signal level.  
As a rule, solo signals are monitored via the control room  
outputs and headphones connector and are displayed by  
the level meters. If a solo switch is pressed, the signals from  
the tape input, Alt 3-4 and main mix are blocked from the  
control room outputs, the headphone connector and the  
level meter.  
LEVEL SETTING:  
Fig. 2.14: Main mix outputs, Alt 3-4 outputs and control room outputs  
When recording to a digital device, the recorder’s peak  
meter should not exceed 0 dB. This is because, unlike analog  
recordings, slightly excessive levels can create unpleasant  
digital distortion.  
MAIN OUTPUTS  
MAIN SOLO (1204FX only)  
The MAIN outputs carry the MAIN MIX signal and are on  
balanced XLR connectors with a nominal level of +4 dBu.  
Fig. 2.11: Control room/phones section, level meter  
When recording to an analog device, the VU meters of the  
recording machine should reach approx. +3 dB with low-  
frequency signals (e.g. kick drum). Due to their inertia VU  
meters tend to display too low a signal level at frequencies  
above 1 kHz. This is why, for example, a Hi-Hat should only  
be driven as far as -10 dB. Snare drums should be driven to  
approx. 0 dB.  
The MAIN SOLO LED lights up as soon as a channel or aux  
send solo switch is pressed. The MODE switch also has to be  
set atSolo.  
ALT 3-4 OUTPUTS  
CD/TAPE  
The ALT 3-4 outputs are unbalanced and carry the signals  
of the channels that you have assigned to this group using  
the MUTE switch. This can be used to route a subgroup to a  
further mixing console for example, or or it could be used as  
a recording output working in tandem with the main output.  
This means you could record to four tracks simultaneously.  
The icing on the cake, so to speak, is that you could connect  
Y-cables to these four outputs and then connect your  
8-track recorder in such a way that you have 2 x 4 tracks (e.g.  
channel 1 feeds track 1 and track 2, etc.). In the first recording  
pass, you record on tracks 1, 3, 5 and 7 and in the second  
pass, on tracks 2, 4, 6 and 8.  
The TAPE switch routes the signal from the TAPE IN  
PFL (1204FX only)  
connectors to the level meter, the CONTROL ROOM OUT  
outputs and the PHONES connector this is a simple way to  
check recorded signals via monitor speakers or headphones.  
The PFL LED indicates that the peak meter is set to PFL mode.  
The peak meters of your XENYX display the level  
virtually independent of frequency. A recording level  
of 0 dB is recommended for all signal types.  
ALT 3-4  
Similarly, the ALT 3-4 switch routes the signal from the  
Alt 3-4 bus to the same path for monitoring purposes.

Caution!You must never use unbalanced XLR  
connectors (pin 1 and 3 connected) on the MIC inputs  
if you intend to use the phantom power supply.

4. Installation  
4.1 Rack mounting  
The packaging of your mixing console contains two 19" rack  
mount wings which can be installed on the side panels of  
the console.  
The control room output is normally connected to the  
monitor system in the control room and provides the stereo  
mix or, when required, the solo signal.

Before you can attach the rack mount wings to the mixing  
console, you need to remove the screws holding the left and  
right side panels. Use these screws to fasten the two wings  
onto the console, being careful to note that each wing fits a  
specific side. With the rack mount wings installed, you can  
mount the mixing console in a commercially available 19"  
rack. Be sure to allow for proper air flow around the unit, and  
do not place the mixing console close to radiators or power  
amps, so as to avoid overheating.

The console is connected to the mains via the cable supplied  
which meets the required safety standards. Blown fuses  
must only be replaced by fuses of the same type and rating.  
Here you can find a list of all presets stored in the multi-  
effects processor. This built-in effects module produces  
high-grade standard effects such as reverb, chorus, flanger,  
delay and various combination effects. The integrated effects  
module has the advantage of requiring no wiring. This  
way, the danger of creating ground loops or uneven signal  
levels is eliminated at the outset, completely simplifying  
the handling.  
4.2 Cable connections  
For unbalanced use, pin 1 and pin 3 have to be bridged  
You will need a large number of cables for the various  
connections to and from the console. The illustrations below  
show the wiring of these cables. Be sure to use only  
high-grade cables.  
IEC MAINS RECEPTACLE  
Balanced use with XLR connectors  
The mains connection is via a cable with IEC mains  
connector. An appropriate mains cable is supplied with  
the equipment.

These effect presets are designed to be added to dry signals.

Tip  
PHANTOM  
This also goes for mixing effects signals with the monitor  
mix. The main difference is that the mix ratio is adjusted  
using the FX TO MON control. Of course, a signal has to  
be fed into the effects processor via the FX control in the  
channel strip for both applications.  
The PHANTOM switch activates the phantom power supply  
for the XLR connectors of the mono channels which is  
required to operate condenser microphones. The red  
+48 V LED lights up when phantom power is on. As a rule,  
dynamic microphones can still be used with phantom power  
switched on, provided that they are wired in a balanced  
configuration. In case of doubt, contact the microphone  
manufacturer!

LEVEL  
tip  
pole 2  
The LED level meter on the effects module should display  
a sufficiently high level. Take care to ensure that the clip  
LED only lights up at peak levels. If it is lit constantly, you  
are overloading the effects processor and this could  
cause unpleasant distortion. The FX control (AUX SEND 2)  
determines the level that reaches the effects module.  
Tip  
(signal)  
After the phantom power supply has been switched  
on, do not connect microphones to the mixer (or  
the stagebox/wallbox). Connect the microphones  
before you switch phantom power on. In addition, the  
monitor/PA loudspeakers should be muted before  
activating the phantom power supply. After switching  
on, wait approx. one minute to allow the system  
to stabilize.

PROGRAM  
You can select the effect preset by turning the PROGRAM  
control. The display flashes the number of the current preset.  
To recall the selected preset, press the button; the flashing  
stops. You can also recall the selected preset with the  
foot switch.  
4.2.1 Audio connections  
Please use commercial RCA cables to wire the 2-track inputs  
and outputs.  
Caution!You must never use unbalanced XLR  
connectors (PIN 1 and 3 connected) on the MIC  
input connectors if you want to use the phantom  
power supply.  
You can, of course, also connect unbalanced devices to the  
balanced input/outputs. Use either mono plugs, or ensure  
that ring and sleeve are bridged inside the stereo plug (or  
pins 1 & 3 in the case of XLR connectors).
