(D POWER Switch
Flip up to turn power ON, and down to turn power OFF.
The VU meter lamps will tight when the power is ON.
A) 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.
Externa!
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 7 (L & R) & AUX RETURN 2 (L & В) `
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).
