Technical Specifications
The public address amplifier shall be a Bogen Model
_________, or approved equivalent, with a full power rat-
ing of _______watts. (Specify: C35/35 watts, C60/60
watts or C100/100 watts.) The frequency response (trans-
former) shall be 70 Hz to 16 kHz ±2 dB†, with less than
1% distortion†. Input sensitivity 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-impedance
balanced microphone input, one dedicated Hi-Z auxiliary
input, and one dedicated telephone line input, as well as a
fourth input that is switch selectable to be either a micro-
phone or auxiliary input.
The microphone inputs shall be equipped with filters to
protect against RF interference. Independent volume con-
trols for each input as well as TREBLE control (±11 dB @
10 kHz) and BASS control (±11 dB @ 100 Hz) shall be
incorporated. A precedence circuit 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-ohm (direct), 8-ohm (C35 & C60 models only), and
16-ohm speaker systems as well as for 25V and 70V con-
stant voltage systems. Two high-impedance outputs shall
be provided to drive a tape recorder or booster amplifier
and, when used with an accessory transformer (WMT1A),
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
19-inch equipment racks, using an optional rack panel kit
(Model RPK50). Dimensions shall be
14-1/2" W x 3-3/4" H x 11" D. Product weight shall be
______lb. (Insert 15 lb. for C35, 17 lb. for C60 or 19 lb.
for C100.)
