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.
