Specifications
Bogen’s M-Class delivers on what contractors need most:
•
Reliability -
Massive power toroid and heat sinks, heavy 14-gauge chassis, Back-Slope™ AC voltage
stabilization, Clip limiters, DC voltage, over-current and thermal protection circuits.
•
Flexibility -
3 modes of operation: 70V Mono, Dual Mono, or Stereo; 2 modular input bays
for a variety of prioritized input types.
•
Power -
up to 600W/ch stereo or 1200W of 70V mono power with low distortion and a high slew rate.
All this wrapped into 2 rack spaces of some of the best looking metal in the industry.
Three, Flexible Operating Modes
Flexible operating modes meet different installation needs.
70V Mono Mode
Dual Mono Mode
Stereo Mode
70V Mono Mode:
Provides a single channel of output for
70V constant voltage speaker systems. Inputs form
a 2x1 mixer with the front panel controls determining
the signal levels from each input.
Stereo Mode:
In stereo mode, the front panel controls allow
independent operation of the two power amp channels.
Dual Mono Mode:
Dual mono provides the same mixer
operation as 70V Mono Mode, but with two amplifier
channels for low-impedance speaker systems. A balance
control is provided to adjust the overall volume level
between the two amplifier outputs. Inputs form a 2x1
mixer with the front panel controls determining the signal
levels from each input.
* Both channels driven at nominal line voltage
