The M450 Stereo/Mono Audio Power Amplifier by Bogen Communications is a powerful audio amplifier system that delivers Flexibility, Power, and Reliability.
Flexibility – 3 modes of operation: Stereo, 70V Mono, or Dual Mono; and 2 modular input bays for a variety of prioritized input types.
Power – up to 450W/ch
Reliability – Massive power toroid and heat sinks; heavy 14-gauge chassis; patented Back-Slope™ AC voltage stabilization; Clip limiters, DC voltage, over-current, and thermal protection circuits.
