POWER Power output into 4ohms resistive > 400W Power output into 8ohms resistive > 225W DISTORTION (Footnote 1) At full power output, all harmonic distortion orders THD <-120dB (< 1000 parts per billion) up to 20kHz (100kHz B.W.) at 400W into 4ohms. THD @ 1kHz is <-134dB (<200 parts per billion). For a sum of 19 and 20kHz tones, each delivering 100W into 4ohms = peak power 400W, intermodulation products each <-120dB relative to output. SMPTE-IM intermodulation products each <-120dB relative to output INPUTS There are 4 input modes: • An unbalanced voltage mode input with an impedance of 100kohm • A balanced voltage mode input with an impedance of 100kohms + 100kohms • A current-mode input with a 50ohm input impedance to minimize cable reflections (to be fed from an infinite impedance current source) • A minimal path voltage mode with an input impedance of 660ohms. The voltage gain of the balanced and unbalanced inputs is 60V/V and 30V/V for the minimal path mode. The gain of current mode is 9V/mA. NOISE The equivalent input noise at the input is 5nV/sqrt(Hz) for the voltage modes and 6pA/sqrt(Hz) for the current mode. SLEW RATE LIMIT Maximum slew rate for both small signal and maximum output voltage is 100V/µs, (which is equivalent to a maximum output voltage at approximately 250kHz.) POWER SUPPLY (Footnote 2) • Active power factor correction minimizes mains current harmonic distortion • Operates at all voltages from 85 through to 270V r.m.s. 45-65Hz, without any internal or external switches • Less than 100 parts per million mains hum and ripple on the amplifier power rails • Conforms with PFC and EU emission standards set for 2002 OVERLOAD= Is protected against most input overloads The power supply protection: • Will cut out if most common faults are detected in the power supply (e.g. over-voltage, master clock at incorrect frequency, excessive temperatures etc) •  DIMENSIONS (per monoblock) Weight: 120 lbs. or 55 Kg Height: 31 inches or 79 cm Width: 16 inches or 40 cm Depth: 16 inches or 40 cm Shipping weight, (one pair including pallet): 352 lbs. or 160 kg
