Bogen C20 Mixer Amplifier

Mixer Amplifier Classic Series C20

• Balanced low-impedance microphone inputs; high impedance auxiliary input
• Mic 1 precedence over Aux with customer-supplied switch
• Tel input with signal activated muting of Aux channel
• Input matching to a telephone line with accessory transformer
• Available with MOH output
• UL and CSA listed

The Classic Series C10 and C20 are rated at 10 and 20 watts respectively. Both models are available with a music on hold output (Models C10MOH & C20MOH).

The amplifiers mix 3 inputs: 2 Mic and Tel, or 1 Mic, 1 Aux and Tel. A second telephone input can be added using an accessory transformer. A built-in circuit provides microphone precedence over the Aux channel when a customer-supplied SPST switch is actuated. The Tel input is signal activated and automatically mutes the Aux channel during a page.

Each input has its own volume control; a treble control is included to adjust the tonal balance of the output. The Tel channel includes screwdriver adjustable mute theshold (VOX) and volume controls.
Balanced and unbalanced outputs are provided for 4, 8, and 16 speaker systems and for 25 volt and 70 volt constant voltage systems. The C10MOH and C20MOH versions include a Music-On-Hold output from the Aux input source. The input is unaffected by paging. Two output taps are provided: 600 @ 1 volt or 8 @ 1 watt. Screw terminals are used for all connections. The output includes a screwdriver adjustable level control on the rear panel.

Thermal and electrical protection is built in and is designed to protect the amplifier against abnormal heat build-up and short circuited or overloaded outputs.
