by qualified Yamaha service personnel.  
• If this device or power supply should be dropped or damaged, immediately turn  
off the power switch, disconnect the electric plug from the outlet, and have the  
device inspected by qualified Yamaha service personnel.  
CAUTION  
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage  
to the device or other property. These precautions include, but are not limited to, the following:  
Power supply/Power cord  
Connections  
• Remove the electric plug from the outlet when the device is not to be used for  
extended periods of time, or during electrical storms.  
• Before connecting the device to other devices, turn off the power for all devices.  
Before turning the power on or off for all devices, set all volume levels to  
minimum.  
• When removing the electric plug from the device or an outlet, always hold the  
plug itself and not the cord. Pulling by the cord can damage it.  
Handling caution  
Location  
• When turning on the AC power in your audio system, always turn on the power  
amplifier LAST, to avoid speaker damage. When turning the power off, the power  
amplifier should be turned off FIRST for the same reason.  
• When transporting or moving the device, always use two or more people.

1INPUT Jack (monaural)  
These monaural input jacks are used to connect micro-  
phones or musical instruments. Each input channel fea-  
tures two types of jacks (INPUT A and INPUT B).  
4INPUT Jacks (stereo)  
These are stereo input jacks that connect line-level  
instruments, such as a synthesizer. Each input channel  
features two types of jacks (INPUT A and INPUT B).  
• INPUT A Jack  
These are balanced XLR-3-31 type input jacks (1:  
Ground; 2: Hot; 3: Cold).  
• INPUT A Jacks  
These are unbalanced phone-jack stereo line inputs.  
• INPUT B Jack  
These are TRS phone-jack type balanced inputs. (T:  
Hot; R; Cold; S: Ground)  
You can connect either balanced or unbalanced phone  
plugs to these jacks.  
• INPUT B Jacks  
These are unbalanced stereo RCA pin-jack line inputs.  
NOTE  
·
Only one type of jack can be used at a time on a single  
channel.

2INSERT Jack  
These jacks are located between the compressor and  
equalizer of the corresponding monaural input channel.  
The INSERT jacks are ideal for connecting devices such  
as graphic equalizers or noise filters into the corre-  
sponding channels. The INSERT jacks are TRS (tip,  
ring, sleeve) phone jacks that carry both the send and  
return signal (tip = send/out; ring = return/in; sleeve =  
ground).

• When turning phantom power on, be sure that only a  
condenser microphone is connected to the INPUT A  
jack of the monaural channel. Other devices may be  
damaged if connected to phantom power. This precau-  
tion does not apply to balanced dynamic microphones,  
however, as these will not be affected by phantom  
power.  
To avoid damage to speakers, be sure to turn off  
amplifiers (or powered speakers) before turning this  
switch on or off. It’s also a good idea to turn the mixer’s  
output controls - STEREO OUT master fader and  
GROUP OUT faders - all the way down. If you omit this  
precaution, you may damage your hearing or your  
equipment.

Controls and Functions  
0COMP Control/Indicator  
EPAN Control  
Adjusts the amount of compression applied to the chan-  
nel. As the COMP knob is turned to the right the com-  
pression ratio increases while the output gain is  
automatically adjusted accordingly. The result is  
smoother, more even dynamics because louder signals  
are attenuated while the overall level is boosted. The  
COMP indicator will light when the compressor oper-  
ates.  
This control determines the stereo positioning of the  
monaural channel signal on the buses.  
Rotate the knob clockwise to pan the signal to the odd  
channels of the GROUP buses and the ST L bus, and  
counter-clockwise to pan the signal to the even chan-  
nels of the GROUP buses and the ST R bus.  
FBAL Control  
Adjusts the left and right volume balance of stereo  
channels. The signal input to the INPUT L jack will be  
sent to the odd channels of the GROUP buses or to the  
ST L bus, and the signal input to the INPUT R jack will  
be sent to the even channels of the GROUP buses or to  
the ST R bus.  
NOTE  
·
Avoid setting the compression too high, as the higher  
average output level that results may lead to feedback.  
AEQ (Equalizer): HIGH, HI-MID, LO-MID, LOW  
This is a four-band equalizer, providing adjustments for  
four frequency bands (HIGH, HI-MID, LO-MID, LOW).  
Setting the gain control to the “” position produces a  
flat response in the corresponding band. Turning the  
gain control to the right boosts the corresponding fre-  
quency band, while turning to the left attenuates the  
band. The HI-MID and LO-MID bands of monaural  
channels provide a frequency control that lets you  
adjust the center frequency.  
GON Switch/Indicator  
When this switch is on, that channel will be enabled and  
the indicator will light.  
NOTE  
·
Even if the ON switch is off, you can turn on the PFL  
switch (K) and monitor the signal before the channel  
fader via the MONITOR OUT jacks and the PHONES  
jack.

These assign the channel’s mute on/off to switches 1–4.  
If you turn on the MUTE master switches (1–4)  
input channels whose corresponding MUTE switch is on  
will be muted.  
These adjust the level of the signals sent from the input  
channel to AUX buses 1–8. These knobs should gener-  
ally be set close to the “” (nominal) position. The sig-  
nal adjusted by these controls is determined by the PRE  
switch (D).  
NOTE  
DPRE Switches  
·
When a channel is muted, the ON indicator (G) will go  
dark.  
For each two buses, these switches select whether the  
signal sent to the AUX buses will be taken after the  
equalizer and before the channel fader (pre-fader), or  
after the channel fader (post-fader). If this switch is ON,  
the pre-fader signal is sent to the AUX bus, and will not  
be affected by the channel fader.  
·
Even if a channel is muted, you can turn on the PFL  
switch (K) and monitor the signal before the channel  
fader via the MONITOR OUT jacks and the PHONES  
jack.  
NOTE  
·
If necessary, the pre-fader signal sent to the AUX buses  
can be changed to the signal before the equalizer by  
changing an internal jumper. A fee will be charged for  
this modification. In this case, the signal will be sent to  
the AUX buses even if the input channel’s ON switch is  
turned off. For details, contact to your Yamaha dealer  
listed at the end of this manual.

1AUX RETURN Jacks  
These are unbalanced phone-jack type line inputs. Sig-  
nals input from these jacks can be sent to the GROUP 1/  
2–7/8, ST L/R, MONO, and AUX 1–4 buses. To the  
MONO and AUX 1–4 buses, a mix of the L/MONO and R  
signal is sent. These jacks are typically used to receive  
the signal returned from an external effect device  
(reverb, delay, etc.).  
NOTE  
·
·
These jacks can also be used as auxiliary stereo inputs.  
If you connect to the L/MONO jack only, the mixer will  
recognize the signal as monaural and will send the identi-  
cal signal to both the L/MONO and R jacks.

These are RCA pin jacks and a mini-phone jack (stereo)  
for inputting a stereo audio source. Use these jacks  
when you want to connect a CD player, and output the  
signal to the ST L/R or MONO bus.  
The “” position of the knob is nominal level (0 dB).  
3Bus Assign Switches  
NOTE  
These switches determine the bus(es) to which the sig-  
nal is received from the AUX RETURN jacks.  
·
If signals are simultaneously input from the 2TR IN jacks  
(RCA pin jacks, mini-phone jack) and the USB connector,  
the signals will be mixed.

Troubleshooting  
Troubleshooting  
Power doesn’t come on.  
• Is the dedicated PW8 power supply properly plugged into  
an appropriate AC power outlet?  
• Is the dedicated PW8 power supply properly connected  
using the included power supply cable?  
The PW8 itself will not power-on unless it is correctly con-  
nected via the included power cable.  
• If the above checks do not identify the problem, call  
Yamaha for service.  
The sound of the bass drum will not move forward in  
the mix.  
• Could you be mixing a phase-reversed signal?  
Try turning on the  
switch to reverse the phase. If you  
are capturing the sound using multiple mics, phase rever-  
sal may be causing cancellation.  
How can I send the pre-EQ signal to an AUX bus for  
monitoring?  
• You can send the pre-EQ signal to an AUX bus by  
changing an internal jumper setting. Turn the AUX PRE  
switch on (pre-fader). In this case, the signal will be sent  
to the AUX bus even if the input channel’s ON switch is  
off.  
How can I monitor the signal of a GROUP bus before I  
send it to the ST L/R bus?  
• With the GROUP section ON switch turned off, turning the  
GROUP section AFL switch on will let you monitor the AFL  
signal of the GROUP bus without sending it to the ST L/R  
(and MONO) bus.  
How can I send a compressed signal to the ST L/R  
bus while sending the uncompressed signal to  
DIRECT OUT jacks for recording?  
• If you connect a compressor (external device) to the  
INSERT jacks and apply compression to the signal being  
sent to the ST L/R bus, the signal before the compressor  
will be sent to the DIRECT OUT jacks. In this case, turn off  
the IM8’s COMP control.  
How can I send the TALKBACK signal only to the  
intercom?  
• In the TALKBACK section, turn on only MATRIX 1-2 (or  
MATRIX 3-4) to send the output of MATRIX 1-2 (or  
MATRIX 3-4) to the intercom.  
How can I play background music from a portable  
audio player?  
• A standard mini-phone type 2TR IN jack is provided on  
the front panel, allowing you to connect your portable  
audio player via a mini-plug cable.  
How can I assign the MC to the MONO bus and also  
record it?  
• Assign the MC’s input channel to the MONO bus, and use  
the REC OUT section bus assign switch to select the  
MONO bus.
