Bogen - C35 Classic Series 35W Public Address Mixer Amplifier, 4-Input PA System, 25V-70V, Rack Mountable, UL Listed - Black

The Bogen C35 Classic Series 35W Public Address Mixer Amplifier is engineered for commercial and institutional environments requiring dependable audio distribution and multi-source mixing. Rated at 35 watts RMS, this mixer amplifier accepts four independent inputs — one balanced low-impedance microphone input (Lo-Z), one high-impedance auxiliary input (Hi-Z), one telephone input (TEL), and a fourth input selectable between microphone or auxiliary — each controlled by its own volume control. Output screw terminals support 4-ohm direct, 8-ohm, 16-ohm, 25V, and 70V transformer-coupled speaker systems for maximum installation flexibility. The TEL input supports telephone paging applications with voice-activated (VOX) AUX muting and variable threshold control. Treble and bass tone controls provide plus or minus 11 dB of adjustment at 10 kHz and 100 Hz respectively. Output jacks allow connection to a tape recorder, booster amplifier, or 600-ohm telephone line via the optional WMT1A accessory transformer. Built-in thermal protection and electronic shutdown safeguard against overheating and short-circuit conditions. The C35 is designed with all-silicon semiconductors and complementary transistor circuitry for long-term reliability. Rack mountable with the optional RPK50 rack panel kit. Listed to UL Standard 60065 for U.S. and Canada. Ideal for offices, schools, retail environments, and houses of worship.

• 35W RMS Power with Multi-Output Compatibility: Delivers 35 watts RMS to support medium-to-large public address installations. Output screw terminals provide connections for 4-ohm (direct), 8-ohm, 16-ohm, 25V, and 70V transformer-coupled speaker systems, covering virtually all commercial PA speaker configurations including constant-voltage 70V distributed audio systems.
• 4 Independent Inputs with VOX Telephone Paging: Mixes four inputs: one balanced Lo-Z microphone, one Hi-Z auxiliary, one telephone (TEL), and one switch-selectable MIC or AUX input. Each input has its own independent volume control. The TEL input supports telephone paging with voice-activated (VOX) automatic AUX muting, and a variable threshold control lets you fine-tune the trigger level for clean handoffs.
• Treble & Bass Tone Controls, Low THD Performance: Front-panel treble and bass controls offer plus or minus 11 dB of adjustment at 10 kHz and 100 Hz respectively, allowing precise tonal shaping for any room acoustics. Frequency response spans 70 Hz to 16 kHz at plus or minus 2 dB (transformer output) and 20 Hz to 20 kHz at plus or minus 1 dB (4-ohm direct), with less than 1% THD at the transformer output.
• Thermal Protection, UL Listed, Rack Mountable: Built-in resettable thermostat in the power transformer protects against abnormal heat build-up and short-circuited or overloaded outputs. Listed to UL Standard 60065 for U.S. and Canada. Rack mountable in 19-inch equipment racks using the optional RPK50 rack panel kit (sold separately). All-silicon semiconductor design with complementary transistor circuitry ensures long-term reliability.
• Recording & Expansion Output Jacks: Rear-panel output jacks allow connection to a tape recorder or booster amplifier for recording or system expansion. A dedicated WMT1A jack supports the optional 600-ohm matching transformer (Model WMT1A, sold separately) to feed a 500/600-ohm telephone line for paging to telephone systems. Operates on 120V AC, 60 Hz with a power draw of 85 watts.
