PRO4.0
2 CHANNEL PROFESSIONAL POWER AMPLIFIER 2x400W/8ohm
Features
- Stereo, parallel and bridge mono mode
- Signal input level, clip and protect indicators
- Three position input sensitivity switch 0.775V/26dB/32dB
- Precision front panel input attenuators
- Ground lift switch
- "Loop through" male XLR connectors to other amplifiers
- Fans exhaust through front grills
- 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
