Professional live sound amplifier

Bogen's M-Series M 300 amplifier provides professional installers with flexible power for commercial sound systems. It operates in stereo, 70V mono, or dual mono modes to suit different venue requirements. Two modular input bays accept a variety of prioritised input modules for customised configurations. The unit is built on a heavy 14-gauge chassis for durability in rack environments.

Upgrade from limited zone amplifiers

This amplifier replaces single-mode units that restrict wiring options for distributed audio. The jump is worth it when a project demands both low-impedance stereo and high-voltage 70V lines from the same chassis. Patented Back-Slope AC voltage stabilisation maintains consistent output when mains supply fluctuates. Integrated clip limiters and thermal protection prevent damage during extended high-level operation.

600 watts per channel stereo headroom

Each channel delivers up to 600W into stereo loads, giving ample headroom for foreground music and paging peaks. A massive toroidal transformer and large heat sinks sustain continuous output without thermal throttling. The 70V mono mode simplifies long cable runs across multiple zones. DC voltage and over-current circuits protect connected loudspeakers from fault conditions.

Questions about this item

What rack space does the 14-gauge chassis require?

The heavy 14-gauge chassis is built for standard rack mounting; allow enough vertical clearance for the massive heat sinks and toroid transformer.

How do I select the 70V mono mode during installation?

Set the amplifier to 70V mono using the rear-panel mode switch before connecting speakers; the step often missed is verifying the setting matches your distributed-line wiring.

When should the internal clip limiters and thermal protection circuits be checked?

The clip limiters, DC voltage, over-current, and thermal protection circuits operate automatically; schedule a professional inspection if the amp repeatedly enters protect mode or after any overheating event.
