The Definition Series of amplifiers represents an unusual type of "solid-state hybrid" design in which a massive, highly regulated, linear analog power supply is combined with a truly "green" discrete analog switching-MOSFET output stage for highly efficient power conversion and low power consumption. The analog power supply and all-discrete MOSFET output stage are pure Audio Research expressions and do not rely on prepackaged modules or other "OEM" solutions common to amplifiers from other manufacturers.
POWER OUTPUT: 200 watts per channel into 8 ohms. 300 watts per channel into 4 ohms, both channels driven, 1% THD.
FREQUENCY RESPONSE: (-3dB points at 1 W) 5Hz to 55 kHz.
INPUT SENSITIVITY: 0.93V RMS for rated output. (32.7 dB Gain) single-ended or balanced.
INPUT IMPEDANCE: 60K ohms single-ended, 120k ohms balanced differential.
INPUTS: (5): BAL 1, BAL 2, CD(SE), Tuner(SE), Aux(SE).
MAXIMUM INPUT: 20V RMS BALANCED, 10V RMS SE.
OUTPUT POLARITY: Non-inverting from single-ended inputs. Balanced pin 2+ (IEC-268).
OUTPUT REGULATION: 0.06dB 8 ohm load to open circuit (Damping factor 167).
HUM & NOISE: 800 microvolts RMS (94dB below rated output IHF A-weighted.)
CONTROLS: Volume (104 steps), Select Input. Push Buttons: Power, BAL/SE, Mono, Mute.
POWER SUPPLY CAPACITANCE: 160,000 uF total.
POWER REQUIREMENTS: 100-125VAC 60Hz (200-250VAC 50 Hz) 445 watts at rated output (200WPC 8 ohms) 735 watts at 300WPC 4 ohms, 38 watts idle. Standby 1 watt.
DIMENSIONS: 19" (48 cm) W(standard rack panel) x 5.25" (13.3 cm) H x 14.25" (36.2 cm) D (front back panel). Optional handles extend 1.5" (3.8 cm) forward of the 1/4" thick front panel. Output connectors extend 0.9" behind rear panel.
