PAGING
The HOUSE PAGE INPUT provides a means to automatically interrupt all program material, and broadcast emergency
messages at a preset level.
The HOUSE PAGE INPUT jack is a balanced 3-pin Euroblock. The Input is line-level with a maximum
signal level of +20 dB. When an input signal greater than –20 dBu is sensed, HOUSE and BOOTH levels
automatically attenuate 40 dB and the HOUSE PAGE INPUT signal routes to both HOUSE and BOOTH
Outputs. The HOUSE PAGE INPUT GAIN is set independent of HOUSE and BOOTH LEVEL settings.
This control is a recessed, screw driver adjusted control located on the rear panel to prevent tampering after
installation.
MIC INPUTS
Both MAIN and AUX MIC Inputs operate separately but identically. The
maximum input and output levels for the EFFECTS loops is +20 dBu.
MAIN & AUX MIC INPUTS are balanced with combination XLR / ¼"
TRS jacks. The maximum input level is +4 dBu. The MAIN MIC GAIN
range is +15 dB to +60 dB, and has a PHANTOM PWR switch to select +12
volt phantom power. The AUX MIC is switchable MIC or LINE level. It has a GAIN control range of +30 to +60 dB in MIC
mode. In LINE mode, the maximum input is +20 dBu with a GAIN control range of 0 to +30 dB. Use the GAIN control in
conjunction with the OL indicator (see below) to set the correct gain.
MAIN & AUX MIC EFFECTS SENDS are unbalanced mono Outputs on ¼" Tip/Sleeve jacks. This Output is used for
external processing, including EQ, dynamic range control, special effects boxes, etc. The MAIN or AUX MIC signals are
always present on each of these respective Outputs.
MAIN & AUX MIC EFFECTS RETURN are unbalanced mono Inputs on ¼" Tip/Sleeve
jacks. This Input receives the signal from an external processor. This is a switching jack—if no
external connection is made to the jack, the EFFECTS SEND signal is internally connected to
it's own EFFECTS RETURN.
MAIN & AUX MIC LEVELS are full-range controls used to set the desired level of each
mic.
OL (overload) indicators light 3 dB before clipping. The signal level is monitored both pre-
and post-tone control. Adjust the rear panel Input GAIN while speaking loudly into the mic so
that the indicator remains off.
HI, MID and LOW controls provide independent tone control for each of the MICS.
The EFFECTS switch engages the MIC EFFECTS loop. As stated above, if an external
connection is not made to the RETURN jack, the MIC EFFECTS switch has no effect.
The ON switch routes the Mic signal to both MASTER HOUSE and BOOTH. In the ON
position, the blue indicator lights and the BOOTH level attenuates 12 dB.
LIGHT TRIGGER OUTPUT
The LIGHT TRIGGER OUTPUT is a mono balanced output on a ¼" TRS jack. The output LEVEL range of
the screwdriver adjustment is off to +6 dB. This Output drives a lighting control box or any other equipment
requiring a mono MASTER signal. Maximum Output signal level on this jack is +20 dBu.
