4 Front & Rear Panels
q ST Input Select Switch
Selects which of the two input signals, from ST Input
jacks A or B, will be used.
In the raised position (?), ST Input jack A is selected
while the lowered position (>) selects ST Input jack B.
w ZONE Select Switch
The same as number r on page 3.
e PEAK Indicator
Indicates peaks in the signal of the post buffer amp.
The indicator will light red when the level reaches +17dB
to warn that clipping is imminent.
r SIGNAL Indicator
The indicator will light when the signal level exceeds
-10dB in the post buffer amp.
t Channel Volume
The same as number u on page 3.
y COMPRESSOR
The COMPRESSOR controls the signal’s volume level
when the level set with the TH (Threshold) Control is
exceeded.
The Compressor is effective on input channels 1-8.
(Refer to page 9 for more information.)
• COMPRESSOR ON/OFF Switch
Switches the COMPRESSOR ON/OFF.
• COMPRESSOR Indicator
Lights when the COMPRESSOR is activated.

• TH Control
Sets the input level (Threshold level) at which the
compressor will function. Rotating the control to the
right allows the compressor to function at lower
volume levels.
• RATIO Control
Sets the ratio of compression that is applied to the
signal when it exceeds the threshold level. Rotating the
knob to the right increases the amount of compres-
sion.
When the knob is turned fully to the left, the signal
will not be compressed.
u PAGING
The PAGING function terminates all signals from each
of the INPUT channels (1-8, ST), INSERT IN and
STACK IN input jacks and only allows the signal from
the PAGING MIC/LINE input jack to be produced. This
function can also be used with a control signal from an
emergency announcement system. (Refer to page 9 for
more information.)
• PAGING GAIN Control
Controls the input sensitivity of the PAGING MIC/
LINE input jack.
An optimum balance between the S/N and dynamic
range is achieved when the PEAK indicator lights
occasionally.
• PAGING PEAK Indicator
Indicates post head amp level peaks in the PAGING
MIC/LINE signal.
The indicator will light red when the level reaches
+17dB to warn that clipping is imminent.
• PAGING SIGNAL Indicator
The indicator will light when the PAGING MIC/
LINE’s post head amp signal level exceeds -10dB.
