REAR PANEL CONNECTIONS
CH (Channel) INSERT HO connectors
A single tip-ring-sleeve 'unbalanced
jack gives in/out
a jumper by closing automatically. A particularly useful
feature allowing modifications of single instruments or
voices. For example, a noise gate could be used to elim-
inate monitor hum from an electric guitar, or a compres-
sor/limiter would add more clarity and punch to a lead
vocal.

(9 POWER switch
Turning the switch on supplies power to the unit. The VU
meters illuminate and the POWER LED lightsup.
IMPORTANT: This switch should be OFF while connect-
ing the console to the mains.
AUX OUT connectors
The AUX
OUTs can also be used to supply two addi-
tional monitor mixes, as AUX OUT controis are incorpo-
rated into each Input Channel. This feature could, for
example,
feed a stereo tape deck, or provide monitor
outputs. for an operator's speaker or a dressing room
speaker.
17) CH (Channel) INPUT connectors
Each input channel has an electronically balanced low--
impedance
XLR type input connector, for fully profes-
sional
microphone
compatibility,
and.
a
balanced
high-impedance tip-ring-sleeve type 1/4" phone jack for
line inputs. An internal phantom power supply, switch-
able in 4-channel
groups,
is provided to handle con-
denser microphones.
In a normal monitoring situation, the signals from the
performers are sent via a splitter system to both the
house PA console and to the monitor mixing console at
these input connectors. With the gain control and 20 dB
pad (see FRONT PANEL section) virtually any source-mi-
crophone or line-can be handled with no problem.
The phantom
power function can
be used with con-
denser type microphones that are designed for use with
an external power supply. Phantom powering is not sup-
plied to the HI-Z phone jack input. Also, the HI-Z input
has priority over the LO-Z XLR type input. So, when both
inputs are connected,
only the signal from
the HI-Z
phone jack is fed to the head amplifier.
