for Surround
The Model 69A provides four buttons and
associated LEDs for selection of the input
source to be monitored. While in most cas-
es only one input source will be monitored
at a time, multiple inputs can be selected
for simultaneous monitoring. This allows
two, three, or all four of the inputs to be
combined (“summed”). While there is no
independent control of the input levels, this
feature can be useful for creating rough
mixes from the source signals. It is also a
fast, effective means of making a “seat-of-
the-pants” check on the phase relationship
between synchronized signals.
The monitor output level is controlled
either through the use of a large, easy-
to-use rotary control, or by enabling the
preset reference level. For operator conve-
nience, the dim function allows the monitor
output level to be reduced by a fi xed dB
amount. The mute all function disables
all monitor outputs by activating the mute
relays on the Model 68A Central Control-
ler. A pushbutton switch allows selection of
either the 6-channel surround or the
2-channel stereo monitor output.
Control of the individual monitor output
channels is provided by the mute/solo
section. One pushbutton switch sets the
operating mode for either mute or solo.
The fl exibility of having both mute and
solo available allows an operator to quickly
select the most comfortable and productive
operating mode. In the mute mode, indi-
vidual channels can be muted or unmuted
as required. In the solo mode, one chan-
nel can be monitored while the others are
automatically muted. If desired, multiple
channels can be simultaneously selected
for “soloing.”
