It is evident that several possible operational setups are possible.

MASTER GAIN CONTROLS
The gai.n controls for line aL1pS 1 (left) and
:3
(right) are located
on the upper ri.ght side of the panel.
The e;ain control for the optional .line amp is located on the =pli-
fier itself, and i.s accessible at the right end of the =plifier
when the console cover is raised.
Signal levels in the console
are adjusted with the input channel mixers so that control should
not need adjustDent after being ini tially set to Da tch the output

Once the gain of line

desired level, interchannel (left-·right) balance can be set using
the channel ba.l ance lever switch (S44) lecated to the left of the

Deter 7'12 is connected across the
top of the left and right channels, and thus reads the difference
in signal levels between channels.
Adjust the level of li.ne amp

(right Daster gain control) until
VU 2
Deter nulls.
This in-
dicates there is no difference in level between rhannels, and thus
the left and right channels are balanced.
It should be obvious
that a nonophonic record [mst be used as a signal source .vhen bel-
ancing the stereo chmmels, since a stereo source seldon has the

The level

the above procedure should not be more than

When the balancing procedure is cODp.leted, S44 should be returned
to the "norraal" position.
CUE-INTERCOM SYSTEM
Controls for the cue,-intercom aLlplifier are located be.low the
VU
meter.
The top control is the gain control, and oontrols the level for
both the "talk" and "listen" functions.
Below the level control
is the cue""'intercoD input selector switch, whicli has 6 positions.
In the "net" position, the network line can be Donitored.

The relilOte 1, 2, 3
and 4 posi ti.ons tie the cue-intercoD aDp to the 1, 2,

lines.
For talkback fad Ii ties, the intercon selector is swi tched
to the desired reDote line and the :xppropriote renote input switoh
is placed in the "TB" position.
The inconing reLote si.gnal line
will then be heard in the panel r;ounted speaker.
When the control
