Overview
The Bogen C-100 is a Classic Series public address mixer-amplifier delivering 100 watts of continuous power. This solid-state amplifier combines mixing functions with power amplification, making it ideal for paging systems, public speaking, and professional audio installations that require reliable, easy-to-integrate audio control. The unit features discrete complementary transistor circuitry for consistent performance across all output stages.
Key Features
- 100W Power Output – sufficient for medium to large venue coverage
- 4 Dedicated Inputs – 1 MIC (Lo-Z), 1 AUX (Hi-Z), 1 TEL (telephone/paging), plus 1 selectable MIC or AUX input
- Independent Volume Controls – individual level adjustment for each input channel
- Tone Shaping – treble and bass controls for audio optimization
- Multiple Output Impedances – 4-ohm direct, 16-ohm, 25V, and 70V transformer-coupled outputs
- Telephone Precedence – TEL input with voice-activated (VOX) mute over AUX for automatic priority during announcements
- Extended Output Options – RCA tape/booster output for recording or chaining additional amplifiers
- Thermal Protection – 105°C thermostat and electrical circuit breaker for safety
