Speck Electronics SSM - Manual (Page 35)

Chapter 4 Operation Section
This control adjusts the overall stereo in-place solo listening level to the
monitor and/or headphone outputs (see the Solo to Monitor Switch, rear
panel section). The adjustment of this control permits the volume of a
soloed signal to match the level of the normal stereo mix.
Keep in mind that the monitor and/or headphone output level controls
still function even when the solo output is activated.
This LED illuminates when any solo or PFL switch is depressed.
The talkback section of the SSM incorporates an internal omni-
directional microphone. This sensitive microphone will operate most
efficiently when the operator speaks at a distance of about two feet from
the mike. This mic is activated by the Talkback Switch and is adjusted
with the Talkback Level Control.
This momentary switch activates the talkback circuit for control room or
house mix communication. When this circuit is activated, it effectively
interrupts the stereo program mix, and allows talkback to the stereo
program 1/4" and XL outputs. The signal to the stereo monitor feed is
muted when the Talkback Switch is enabled.
This control adjusts the volume of the talkback circuit to the program
output. The suggested setting for this control is approximately the two
o'clock range and adjust as necessary.
These 18 segment VU (volume units) meters indicate the relative levels
of the stereo program feed and are sensitive from -31db to +5db.
Depending on the position of the rear panel Meter Sensitivity Switch
(see rear panel), a meter reading of 0VU reflects a mixer output level of
either +4dbm, the industry professional standard, or -18dbm. The latter
is sufficiently low enough to allow the SSM to be plugged into an
external consoles synth or mike inputs. This circuit was designed to
approximate the ballistics of a "taut band" analog style VU meter.
These 18 segment VU (volume units) meters indicate the relative levels
of the solo/PFL signals or the effects send signals, and are sensitive from
-31db to +5db. 27. Solo Master Level Control
