POWER Switch
Flip up to turn power ON, and down to turn power OFF.
The VU meter lamps will light when the power is ON.
PHANTOM MASTER Switch
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 AUX 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).
