Operating Manual
Congratulations!
You are the proud owner of a Yamaha MC-series Mixing Console. Whether you
chose the 8, 12 or 16-channel model, your Yamaha mixing console is a high-quality
product that will give you superior performance in a wide range of applications. In
addition to offering a versatile mixing system, the MC-series consoles offer electronically balanced inputs and stereo outputs to maintain optimum signal quality over
long cable runs, a versatile 3-band equalizer with sweepable mid-frequency EQ on
each input channel, three independent AUX submix systems for external effects
routing or additional power amplifier feeds, cue switches for independent monitoring of all input channels and busses, and a built-in talkback system for convenient
communication.
Of course,
great sound that Yamaha is famous for. We urge you to read this operation manual
thoroughly in order to make the most of the mixer’s many features and controls.
the MC-series mixing consoles also offer the high standard of quality and

PRECAUTIONSPRECAUTIONS
1. AVOID EXCESSIVE HEAT, HUMIDITY, DUST AND
VIBRATION
Keep the unit away from locations where it is likely to be
exposed to high temperatures or humidity–such as near
radiators, stoves, etc. Also avoid locations which are
subject to excessive dust accumulation or vibration which.
could cause mechanical damage.
2. AVOID PHYSICAL SHOCKS
Strong physical shocks to the unit can cause damage.
Handle it with care.
3. DO NOT OPEN THE UNIT OR ATTEMPT REPAIRS OR
MODIFICATIONS YOURSELF
This product contains no user-serviceable parts. Refer all
maintenance to qualified Yamaha service personnel. Opening the unit and/or tampering with the internal circuitry
will void the warranty.
4. MAKE SURE POWER IS OFF BEFORE MAKING OR
REMOVING CONNECTIONS
Always turn the power OFF prior to connecting or disconnecting cables. This is important to prevent damage to
the unit itself as well as other connected equipment.
5. HANDLE CABLES CAREFULLY
Always plug and unplug cables–including the AC cord–by
gripping the connector, not the cord.
6. CLEAN WITH A SOFT DRY CLOTH
Never use solvents such as benzine or thinner to clean the
unit. Wipe clean with a soft, dry cloth.
7. ALWAYS USE THE CORRECT POWER SOURCE
Make sure that the power source voltage specified on the
rear panel matches your local AC mains supply.
U.S. & Canadian Models: 120V AC, 60Hz
General Model: 110 — 120/220 — 240 V AC, 50/60Hz

Input Channels
PAD Switch
This switch attenuates the signal applied to the corresponding rear-panel HI-Z or LO-Z input by
20 dB prior to the head amplifier and input gain control. The PAD switch effectively increases
the range of input signal levels that can be handled by the mixer, preventing overloading of the
input circuitry when receiving high-level signals.
GAIN Control
This control adjusts the input sensitivity of each input channel between –60 dB (0.775 mV)
and –20 dB (77.5 mV) when the PAD switch is OFF (between –40 dB and 0 dB when the PAD
switch is ON). Continuously variable gain control allows optimum matching with virtually any
microphone or line source.
CLIP LED Indicator
The CLIP indicator LED lights when the post-EQ signal of the corresponding channel’s input
reaches a level 3 dB below the clipping level of the channel’s circuitry. If the CLIP indicator
lights more than only briefly on high-level transients it is necessary to decrease the input sensitivity of the channel using the GAIN control and PAD switch or, if this does not provide
sufficient attenuation, to reduce the output level of the source connected to that channel’s
input.
3-band Equalizer
The equalizer section provided on each input channel comprises shelving LOW and HIGH controls, and a peaking MID control with a MID FREQ control that permits sweeping the midrange
center frequency from 350 Hz to 5 kHz.

AUX Controls (1,2 & 3)
The MC-series mixing consoles have three independent AUX busses which are fed by the
corresponding AUX controls on the input channels. Each AUX control determines the level of
the signal sent from that channel to the correspondingly numbered AUX mixing buss, which in
turn feeds the correspondingly numbered AUX SEND control and AUX SEND jack on the
console’s rear panel. The AUX controls can be used to determine the amount of signal from the
corresponding input channel sent to external effect devices or power amps fed by the AUX
SEND jacks:
*
AUX 1 is factory pre-wired for pre-EQ/pre-fader operation, so the AUX 1 signal is not
affected by the setting of the channel EQ controls or fader. An internal jumper allows the
AUX 1 control to be rewired for post-EQ/post-fader operation.
*
AUX 2 and AUX 3 are factory pre-wired for post-EQ/post-fader operation, so the AUX 2
and AUX 3 signals are affected by the setting of the channel EQ controls and fader. Internal
jumpers allow the AUX 1 control to be rewired for pre-EQ/pre-fader operation.
*
An internal POST EQ jumper allows the AUX controls to be further re-configured for
post-EQ/pre-fader operation.

PAN Pots
The PAN pot determines the position. in the stereo sound field at which the sound from that
channel is heard. Rotated fully counterclockwise the channel signal will be delivered from the
left stereo output only, and will be heard at the far left of the sound field. If the PAN pot is
turned fully clockwise, the sound from that channel will appear at the far right of the stereo
sound field. If the PAN pot is set at its center position, the channel signal will be sent equally
to both the left and right channels, causing the sound to appear at the center of the sound field.
Intermediate PAN pot settings cause the sound to be heard at the corresponding position.
CUE Switch
When the CUE switch is pressed, the pre-EQ/pre-fader signal from that channel is fed to the
PHONES output via the CUE/PHONES level control. The channel cue signal will be added to
any other active cue signal. If you want to monitor only the signal from a single channel, make
sure all other CUE switches are turned OFF.
