• If the compressors have been con-
figured not to function (disabled), the
meters will get their biggest workout.
Depending on the setting of the input
and master output controls, all ten seg-
ments of each meter may often come
into play.
Reference Tone
A sine-wave tone can be connected to
the two output buses, serving as a refer-
ence signal for local and remote use. A
pushbutton switch selects its status; when
the switch is in its on (in) position tone is
connected to both output bus 1 and 2. A
dual-color LED indicator, which is located
directly below the switch, lights red when-
ever tone is being sent to the main buses.
(The LED lights green when the Model
742 is operating and the tone is not as-
signed to the output buses.) The level of
the tone generation circuitry is adjusted
at the factory to match the Model 742’s
internal operating level. When the tone is
connected to the output buses, the master
level controls should be adjusted to give
+4 dBu indications on the level meters.
Monitor Section
The monitor section can assist an operator
in obtaining the best performance from the
Model 742 and associated equipment. The
monitor section supports the connection
of both a loudspeaker system and a head-
phone device. The two monitor outputs
are line-level and designed to be con-
nected to audio power amplifier channels
and associated loudspeakers. Alternative-
ly, they can be connected to “amplified”
loudspeakers that contain internal power
amplifiers. The headphone output, located
on the back panel, is designed to support
stereo devices.
Monitor output 1, and the left channel of
the headphone output, use output bus 1
as their audio source. Monitor output 2,
and the right channel of the headphone
output, use output bus 2 as their audio
source. A rotary control sets the output
levels of the headphone channels and, de-
pending on the Model 742’s configuration,
may also control the level of the monitor
loudspeakers. Understanding and becom-
ing comfortable with using the monitor
section is important in obtaining optimal
Model 742 performance.
