Specifications
The amplifier shall be a model _____, rated at ____ watts
RMS (insert GS35/35 watts, GS60/60 watts, GS100/100
watts or GS150/150 watts).
The amplifier shall accommodate up to 6 Lo-Z balanced
microphones, 2 Hi-Z auxiliary sources and a telephone pag-
ing input (Mic 5 shall be switch-selected for mic or tele-
phone line; Mic 6 switch-selected for microphone or Aux 1).
Mics 1 through 4 shall use XLR-type connectors; Aux input
shall be via RCA phono jacks and all other connectors shall
use screw terminals. Phantom power shall be supplied for
use with condenser microphones. 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 20 Hz
to 20 kHz +0/-1 dB at rated power. Distortion shall be 0.3%
typically, from 20 Hz to 20 kHz direct at rated power, and
from 65 Hz to 20 kHz transformer @ -2 dB.
The amplifier shall include an Aphex Aural Exciter circuit,
variable loudness contour control, and dual function equaliz-
er. The equalizer shall be switch selectable for feedback con-
trol or acoustic shaping and shall include 10 center-detent
slide controls providing ±12 dB of boost or cut from 62.5
Hz to 16 kHz in acoustic mode and from 125 Hz 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 tele-
phone line using an accessory transformer (Model
WMT1A). A Preamp out/power amp in circuit shall be pro-
vided to insert signal processing equipment.
The amplifier shall be rack mountable using an accessory
rack panel kit (GSRPK). It shall be UL and CSA listed and
shall be backed by a 3-year warranty.
