C35, C60 & C100
The Bogen Classic Series Models C35, C60, and C100 are public address mixer amplifiers that provide mixing of microphones, telephone, and auxiliary sources.
Description
Output screw terminals are provided for 4-ohm (direct) and 8-ohm, 16-ohm, 25V and 70V (transformer-coupled) speaker systems. Output jacks let you connect to a tape recorder or an additional booster amplifier, or
feed a 600-ohm telephone line when an accessory transformer (Model WMT1A) is used.

The public address amplifier shall be a Bogen Model
Architect _________, or approved equivalent, with a full
and Engineer power rating of _______watts. (Specify: C35/35
Specifications watts, C60/60 watts or C100/100 watts.) The frequency response (transformer) 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 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 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 microphone or auxiliary input.
The amplifier shall contain a resettable thermostat in
the power transformer to protect against heat buildup and short-circuited or overloaded connections.
The microphone inputs shall be equipped with filters
to protect against RF interference. Independent volume controls 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 customersupplied external switch is actuated.
The amplifier shall provide output impedances of 4(direct), 8-, and 16-ohm speaker systems as well as
for 25V and 70V constant voltage systems. Two highimpedance 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.
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. Shipping weight shall
be ______lb. (Insert 16 lb. for C35, 18 lb. for C60 or
20 lb. for C100.)
