Description: Solid-state monoblock power amplifier, with active power-factor correction. Inputs: 1 unbalanced, 1 balanced. Output power: >200W into 8 ohms (23dBW), >350W into 4 ohms (22.4dBW). Distortion: at full power output, all harmonic distortion orders <-114dB up to 20kHz (<4000 parts per billion or <0.0004%). THD: <-128dB at 1kHz, or <400 ppb. Intermodulation products: all <-114dB relative to power output for sum of 19+20kHz tones, each delivering 87.5W into 4 ohms or 50W into 8 ohms or SMPTE-IM. Noise: equivalent input noise at input, 5nV/sqrt(Hz). Slew-rate limit: maximum slew rate for small-signal and maximum output voltages is 100V/µs (equivalent to a maximum output voltage at approximately 250kHz). Input impedance: 100k ohms, both inputs. Voltage gain: 49V/V (33.8dB), both inputs. Overload: 1µs recovery from hard overload at 20kHz into 4 ohms. Protection: short-circuit-proof; overcurrent limiting; gradual power limiting if amplifier becomes too hot. Will cut out if a continuous DC offset appears on output or if output current exceeds 12A average continuously over a period of a few minutes; protection against most input overloads. Power-supply protection: will cut out if most common faults are detected in the power supply (eg, over-voltage, master clock at incorrect frequency, excessive temperatures, etc.). Protected against most mains transients. Operating voltage: 85-270V RMS, 45-65Hz, without internal or external switches.
