Bogen M300 Overview

The M300 M-Class Power Amplifier from Bogen is an amplifier that produces 300W stereo and 600W mono output power. This powerful amp allows installation of up to 2 input modules. These modules can be used for a variety of professional installations such as inputs from microphones, telephone systems, stereo sources, mono sources, or daisy-chaining of amplifiers for sound reinforcement applications, and more.

The M300 relies on a massive power toroidal transformer. These amplifiers are built for solid performance with low distortion and a high slew rate. Output module circuitry is located away from input module circuitry, minimizing noise and ground loops. The amplifiers require little maintenance and cleaning as internal electronic components are located outside of the forced air-stream flow. Front-mounted fan filters provide easy removal and cleaning.

The M-Class amplifier is enclosed in a heavy-duty, 14-gauge chassis. Three modes of operation are available including 70V mono, dual mono, and stereo. This full featured amp is packaged in only 2 rack units of space and can be stacked above or below other units without requiring extra ventilation space. The M300 M-Class Power Amplifier includes two fan filters with two grilles, a control-knob cover, four rubber feet with screws, two rack ears, and a preinstalled balanced input module.
