MX4200
4 CHANNEL PROFESSIONAL POWER AMPLIFIER 4x140W/8ohm
Features
- 4 channel mode, bridge mono (channel-pair) mode
- Signal, clip and protect indicators
- Front panel input attenuators
- Channel inserts for processing
- Switchable high pass filter - low frequency roll-off to prevent transformer saturation in distributed systems
- Channel 1 split switch - connects channel 1 input to other selected amplifier channels
- Input overload limiter - automatically reduces channel gain when steady or excessive clipping is detected
- Output overload protection - automatically reduces channel gain when the amplifier senses mismatched loads
- Soft startup protection - gradually increases amplifier gain after the amplifier is turned on
- Thermal overload protection - activates when excessive heatsink or power transformer temperatures are detected
- Short circuit protection - attenuates the signal and disconnects the load
- DC voltage offset protection - disconnects output instantly to minimise the risk of speaker damage
