Technical
Specifications
The public address amplifier shall be a Bogen Model
_________, or approved equivalent, with a full power
rating of _______watts. (Specify: C10/10 watts or
C20/20 watts.) The frequency response shall be
70Hz to 16kHz ±1dB, with less than 1% distortion at
rated power output. Input sensitivity shall be 600μV
for low-impedance balanced microphones, 85mV for
auxiliary inputs, and 75mV for the telephone input.
Hum and noise shall be 55dB below rated output for
the MIC input, and 70dB below rated output for the
AUX and TEL inputs.
The amplifier shall provide simultaneous mixing of
two low-impedance balanced microphones and one
telephone input; or one microphone, one auxiliary
input, and one telephone input. The unit shall have a
front panel selector switch which shall allow one of
the input channels (MIC 2/AUX) to be selected for use
as a microphone or an auxiliary input. It shall be pos-
sible to mute the auxiliary input when a customer-sup-
plied SPST switch is attached to the AUX MUTE ter-
minals on the rear panel.
The TEL input shall provide signal-activated paging
with muting of the AUX channel. A VOX threshold
control shall be included to eliminate activation of the
channel by noise on the telephone line. The thresh-
old control and TEL volume control shall be located
on the rear panel.
The microphone inputs shall be equipped with filters
to protect against RF interference. Independent vol-
ume controls and a treble cut control (-11dB @
10kHz) shall be incorporated.
The amplifier shall provide output impedances of 4-,
8-, and 16-ohm speaker systems as well as for 25V
and 70V constant voltage systems.
The amplifier shall contain a self resetting thermostat
in the power transformer to protect against heat build-
up and short circuited or overloaded connections.
The amplifier shall be mountable in 19-inch equip-
ment racks, using an optional rack panel kit (Bogen
Model RPK35B), or in a flush-in-wall mounting cabi-
net with tilt-out locking panel (Bogen Model WMK1).
Dimensions shall be 11-3/8" W x 2-7/8" H x 7-3/8" D.
Product weight shall be 5 lbs. for Model C10 and
6 lbs. for Model C20.
