Details
Controls: Independent input level control per channel (front panel), 70V/100V selector switch (rear panel), AC power switch, status indicators (signal, clip, thermal)
I/O: Euroblock connectors for audio and control signals; switchable 70V/100V operation modes; built-in limiter with short circuit, open circuit, thermal, ultrasonic, and RF protection; power-on/off muting
Notable use: 4-channel Class D amplifier for 70V/100V commercial installations
Notes: Class D switching amplifier per instructions: analog_or_digital kept 'analog' (analog audio input path) with the Class D amplification topology captured in the 'topology' field, not analog_or_digital -- this is the flagged judgment call the task specifies. THD <0.1%; damping factor (30-400Hz @8ohm) >200; crosstalk (1kHz/20Hz-20kHz) >70dB. Internal cooling fan present (despite Class D efficiency). Dimensions 19.02"Wx1.73"Hx14.17"D, weight 13.67lbs. price_usd from B&H Photo Video search snippet ($1,199.00; one listing showed $999.00 -- used the higher/more commonly cited figure, flagging the discrepancy).
