Technical
Specifications
The public address amplifier shall be a Bogen Model
_________, or approved equivalent, with a full
power rating of _______watts. (Specify: C35/35
watts, C60/60 watts or C
1
00/
1
00 watts.) The fre-
quency response (transformer) shall be 70 Hz to
1
6
kHz ±2 dB
†
, with less than
1
% distortion
†
. Input sen-
sitivity shall be 600µV for low-impedance balanced
microphones, 85mV for auxiliary inputs, and 75mV
for TEL input. Hum and noise shall be 55 dB below
rated output for the MIC inputs and 70 dB below
rated output for the AUX and TEL inputs.
The amplifier shall provide one dedicated low-imped-
ance balanced microphone input, one dedicated Hi-Z
auxiliary input, and one dedicated telephone line
input, as well as a fourth input that is switch selec-
table to be either a microphone or auxiliary input.
The microphone inputs shall be equipped with filters
to protect against RF interference. Independent vol-
ume controls for each input as well as TREBLE con-
trol (±
11
dB @
1
0 kHz) and BASS control (±
11
dB
@
1
00 Hz) shall be incorporated. A precedence cir-
cuit shall mute the AUX 2 input when a customer-
supplied external switch is actuated.
The amplifier shall include a TEL volume control to
adjust the telephone paging level and a VOX volume
control to adjust the TEL input signal level trigger
point for automatic muting of the AUX inputs.
The amplifier shall provide output impedances of 4-
(direct), 8-, and
1
6-ohm speaker systems as well as
for 25V and 70V constant voltage systems. Two high-
impedance outputs shall be provided to drive a tape
recorder or booster amplifier and, when used with an
accessory transformer (WMT
1
A), to feed a 600-ohm
telephone line.
The amplifier shall contain a resettable thermostat in
the power transformer to protect against heat build-
up and short-circuited or overloaded connections.
Provision shall be included to mount the amplifier in
1
9-inch equipment racks, using an optional rack panel
kit (Model RPK50).
Dimensions shall be
1

be ______lb. (Insert
1
6 lb. for C35,
