protects the power supplies from overload
- Dual and Mono switch
- Input attenuation controls for each channel’s
output
- Rack mountable
- Standby mode
- Protection systems for thermal protection

response of +-10 degrees form 20 to 20kHz at 1 watt
- Total
harmonic distortion (TDH) less than 0.05% at full power (from 20 Hz to
1kHz) increasing linearly to less than 0.1% at 20kHz
- Power
output not less than 200 watts per channel full range
