MIC INput Connector

This is a three pin X LR-type co nnecto r fo r use
with balanced signals with an i mpedance of fro m
50 t o 600 o hms . While the co nnecto r is identified
as a "M IG" input, in actuality it can be used fo r
balanc ed L I N E LEVE L signal as wel l .
By using the T R I M and 30 dB Pad Switch the
MIG I Nput Co nnecto r can accept balanced line
level signals of +28 dBm ( 1 9.5 V).

LINE INput

This 1 /4" Pho ne jack is pro vided fo r use with
unbalanced Ll N E LEVEL signals with a sou rce
impedance o f 1 0 k oh ms o r less.

ONLY
These RCA-type pho no jacks are NOT located
with the rest of the channel input co nnecto rs,
but can be fo und near the PGM OUTputs.
Signals f ro m these j acks are internally ro uted
to channels 1 -8 fo r remix and talent cues. To
the mo nito r system fo r co ntrol roo m mo nito ring
of 4 o r 8 track reco rders without having to
change the co ntro ls o r setting of the input
channels.

LI N E Switch
This switch determines the signal to be ro uted
thro ugh the input channels. I n the "up" positio n
(mic). the signal fro m the X L R is selected. I n
the Ll N E o r "do wn" po sitio n, the signal in the
channel will be either the signal fro m the L l N E
I N co nnecto r, o r the TAPE I Ns o n inputs 1-8
ONLY. The tape signal is auto matically available
if no signal is plugged into the 1 /4" L I NE I Nput
jack .

Pad Switch

The pad switch allows the additio n of a 30 dB
resistive pad to the channels' MIG input level.
This is pro vided fo r use and co ntro l of either
extremely high mic signals o r when the X LR is
used with balanced line level signals.
0T R I M
This dual co ncentric co ntro l is used i n co njunc­
tio n with the OL (OverLoad) Indicato r. T R I M
will reduce the level o f those input signals which
wo uld o therwise o verload the channel's elec­
t ro n ics. Each channel has a M IG T R I M and a
