PRECAUTIONS
I
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.
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. Open
ing 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 dis
connecting 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: 120VAC,60Hz
General Model; 110 - 120/220 - 240 V AC, 50/60Hz
FRONT PANEL CONTROLS
Input Channels
O pad Switch
This switch attenuates the signal applied to the corresponding rear-panel Hl-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.
Q GAIN Control
This control adjusts the input sensitivity of each input channel between —60dB (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.
0 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 sensi
tivity 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.

O 3-band Equalizer
The equalizer section provided on each input channel comprises shelving LOVV and HIGH con
trols, 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 PQST 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.
Ql CUE Switch
When the CUE switch is pressed, the pre-EQ/pre-fader signal from that channel is fed to the
PHQNES 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.
0 Channel Fader
This is the main level control for each input channel. It determines the level of the signal sent
from the corresponding input channel to the master stereo buss. The settings of the input
channel faders determine the "mix" or balance of sound levels between the instruments or
other sources connected to the inputs.
* If a channel is not being used, its fader should be set to the minimum position to prevent
unwanted noise from being added to the main program signal.

0 AUX SEND (1,2 & 3) Controls & CUE Switches
These adjust the overall output level of the auxiliary
"mixes" set up using the AUX 1, AUX 2 and AUX 3 con
trols on the input channels. AUX SEND 1 sets the overall
level of the AUX 1 mix signal appearing at the AUX
SEND 1 jack, AUX SEND 2 sets the overall level of the
AUX 2 mix signal appearing at the AUX SEND 2 jack,
and AUX SEND 3 sets the overall level of the AUX 3
mix appearing at the AUX SEND 3 jack. These controls
should be used to optimally match the AUX SEND out
put level of the mixing console to the input sensitivity of
the effect unit, signal processing device or amplifier used.
The CUE switches associated with each AUX SEND con
trol can be used to send the corresponding AUX SEND
signal to the PHONES jack via the CUE/PHONES level
control. The AUX cue signal will be added to any other
active cue signal. If you want to monitor only the signal
from a single AUX buss, make sure all other CUE switches
are turned OFF.
D AUX RTN 1 & AUX RTN 2 Controls
These controls adjust the level of the signal received at the
rear-panel AUX RTN jacks and mixed into the main
stereo program. Since stereo AUX returns are provided
(AUX RTN 1 L & R, AUX RTN 2 L & R) the AUX RE
TURN controls simultaneously adjust the level of the
signals appearing at the corresponding L and R return
inputs. The returned L and R channel signals are sent to
the L and R stereo buss lines. If only a single-channel
signal is returned (i.e. a plug is inserted into only the L or
R return jack), the signal will be fed to both the L and R
channels of the stereo buss.
0 Talkback ON Switch
Pressing this switch activates the talkback microphone plugged into the talkback mic connector,
allowing voice communication from the console operator to the STEREO, AUX 1, AUX 2 or
AUX 3 busses according to the setting of the talkback assignment switches.
® TB (Talkback) Level Control
Adjusts the level of the talkback signal sent to the selected buss.

Talkback Microphone Connector
This female XLR type connector accepts just about any standard 50 ~ 600 ohm microphone
for talkback pickup. A gooseneck-type microphone that can be positioned for the most com
fortable operation is an excellent choice.
({) Talkback Assignment Switches (AUX 1/AUX 2/AUX 3/ST)
These switches allow the talkback signal to be fed to the STEREO, AUX 1, AUX 2 or AUX 3
busses. Any number of switches may be ON at the same time, so you can "talk back" to a
number of the console's busses at once.

Turn this switch ON to apply +48 volts DC to the LO-Z
XLR input connectors when using phantom-powered
condenser microphones.
* NEVER turn the PHANTOM MASTER switch ON
when applying line-sources to the LO-Z inputs.
^ Hi-Z and LO-Z Input Connectors
Each input channel offers a choice of two input connec
tors: a balanced LO-Z (low-impedance) XLR-type connec
tor and a HI-Z (high-impedance) tip-ring-sleeve 1/4"
phone jack. The LO-Z inputs are primarily intended for
use with professional low-impedance microphones or
electronic instruments having low-impedance balanced
outputs. The HI-Z inputs will accept either balanced or
unbalanced signals from high-impedance microphones,
musical instruments or other source equipment.
® INPUT CH INSERT IN/OUT Jacks
These jacks permit inserting compressors, limiters or other
types of external signal processing equipment between the
head amplifier and EQ stage of each input channel. The
jacks are tip-ring-sleeve types, in which the tip is SEND
(the output from the head amplifier), the ring is RETURN
(the input to the EQ stage), and the sleeve is ground.
External equipment may be inserted using "Y" cables
which branch the SEND and RETURN lines from a tip-
ring-sleeve phone plug to two separate mono phone plugs.

® AUX SEND (1,2 & 3) Jacks
These jacks deliver the AUX 1, AUX 2 and ALTX 3 mixes,
respectively, to feed an external effect device or power
amplifier. Nominal output level/impedance is +4 dB/
600 ohms.
AUX RETURN 1 (L & R) & AUX RETURN 2 (L & R) Jacks
The mono or stereo output from effect units fed by the
AUX SEND jacks can be returned to the main stereo
program mix via these jacks. Note that each AUX RE
TURN offers independent return inputs for the left and
right busses, accommodating the return signal from effect
units featuring stereo outputs. Nominal input level/im
pedance is +4 dB/600 ohms.
AUX SUB IN & ST SUB IN Jacks
These five jacks permit "cascading" two MC-series mixing
consoles to increase the number of available input chan
nels. The AUX OUT jacks from the first (slave) console
should be connected to the corresponding AUX SUB IN
jacks of the second (master) console, and the STEREO
outputs from the slave console should be connected to the
corresponding ST SUB IN jacks on the master console.
STEREO OUT L & R Connectors
The MC-series mixing consoles provide balanced XLR con
nector outputs from the main stereo buss. The signal
delivered is a stereo mix of the input channel signals and
the signals returned to the AUX RETURN jacks. The
STEREO OUT signal will normally be used to drive a
power amplifier and speaker system, powered keyboard
speakers or a main house mixing console. Nominal output
level/load impedance is +4 dB/600 ohms.
NOTE: The. MC-series mixing console XLR connectors are
wired according to DIN specifications. Pin 1 is
shield (ground), pin 2 is hot (signal high) and pin 3
is cold (signal low).

APPLICATION EXAMPLE
In the system shown below the MC1602 is used as the main
console in a sound reinforcement system. Three vocal micro
phones, six drum microphones, a microphone from the guitar
amplifier and another from the bass amplifier are connected
to 11 of the 16 available LO-Z inputs. The line-level stereo
outputs from an on-stage keyboard mixer and the stereo
outputs from an electronic percussion system are fed to four
Hl-Z inputs. A total of 15 input channels are thus used, leav
ing one free — just in case. The AUX 1 mix system feeds
on-stage power amplifiers and monitor speakers for the
STAGE MONITOR
SPEAKERS
performers. The AUX 2 system is used to drive a digital
reverb/effects unit to add ambience and effects where neces
sary. The AUX 3 system feeds a tape recorder to make a
rough mono recording of the performance. T.he STEREO
OUT connectors drive the main house power amplifiers and
speaker systerri.
This is just one possible way of setting up the MC1602 for
a sound reinforcement application. The actual setup you use
will, naturally, be dictated by your own particular system
requirements.
