Specifications
The amplifier shall be a model _____, rated at ____ watts RMS
(GS150D/150 watts, GS250D/250 watts).
The amplifier shall accommodate up to 6 Lo-Z balanced micro-
phones, 2 Hi-Z auxiliary sources and a telephone paging input
(MIC 5 shall be switch-selected for MIC or telephone line; MIC
6 switch-selected for MIC or AUX 1). MIC 1 through 4 shall use
XLR-type connectors; AUX inputs shall be via RCA phono jacks
and all other connectors shall use pluggable screw terminals.
Phantom power shall be supplied for use with condenser micro-
phones. Microphone precedence connections shall be included
for MIC 1, 2, 3, 5/TEL, 6/AUX 1 and AUX 2.
The amplifier shall provide a frequency response from 65 Hz to
20 kHz +0/-2 dB at rated power. Distortion shall be 0.3% typically.
The amplifier shall include an Audio Enhancement circuit, vari-
able
loudness contour control, and dual function equalizer. The
equalize
r shall be switch selectable for feedback control or
acoustic shaping and shall include 10 center-detent slide con-
trols providing ±12 dB of boost or cut from 62.5 Hz to 16 kHz in
acoustic mode and from 125Hz to 8 kHz in feedback control mode.
The amplifier shall include automatic level control to provide
consistent output regardless of who is paging, automatic muting
complete with a VOX circuit, and a variable mute level.
Provisions shall also be included for remote volume control,
using an accessory control unit (GSRVC).
Outputs shall be provided for 4- and 8-ohm speakers and for
25V, 25VCT, and 70V distributed systems. Additional outputs
shall be provided to feed a booster amp and tape recorder.
A dedicated output shall permit feeding a 600-ohm telephone
line using an accessory transformer (Model WMT1A).
A Preamp out/power amp in circuit shall be provided to insert
signal processing equipment.
The amplifier shall be rack mountable using an accessory rack
panel kit (GSDRPK). It shall carry the necessary safety agency
listings for both the US and Canada.
