Description; Front Panel - Bogen C10 Installation And Use Manual

Description

Bogen Models C10 and C20 public address amplifiers are rated at 10 and 20 watts, respectively, and are UL and
C-UL listed.
The amplifiers accommodate low-impedance microphones and high-impedance auxiliary sources. A front panel
selector switch offers a choice of either two low-impedance balanced microphones (MIC1, MIC2), or one micro-
phone and one auxiliary input (MIC1, AUX). The AUX input can be muted when a customer-supplied SPST nor-
mally open switch is used for microphone precedence. Independent volume controls and a treble control, for tonal
balance, are provided.
Balanced and unbalanced outputs are provided for 4-, 8-, and 16-ohm speakers and for 25- and 70-volt constant
voltage systems. An accessory transformer, Bogen Model WMT1A, can be installed to provide input- and output-
matching to a telephone line.
The amplifiers operate from a 120V AC, 60 Hz source. A thermostat enclosed in the power transformer protects
the unit against overloads.
The amplifier also accommodates a transformer-balanced TEL/page input with VOX detector for muting the AUX.
