Audio Research Reference 6


Frequency Response: +0-3dB, 0.5Hz to 200kHz at rated output (Balanced, 200k ohms load).

Distortion: Less than .01% at 2V RMS BAL output.

Gain: Main output: 12dB Balanced output, 6dB SE output. Record out: 0dB (Processor input: 0dB SE output).

Input Impedance:  120K ohms Balanced, 60K ohms SE. Inputs 4 balanced, 4 single-ended. Assignable processor passthrough.

Output Impedance: 600 ohms Balanced, 300 ohms SE Main (2). 20K ohms minimum load and 2000pF maximum capacitance. Outputs (3): 2 main, 1 record out (XLR and RCA connectors).

Output Polarity: Non-inverting.

Maximum Input: 20V RMS BAL, 10V RMS SE.

Rated Outputs:  2V RMS (1V RMS SE) into 200K ohm balanced load (maximum balanced output capability is 30V RMS at less than 0.5% THD at 1kHz).

Crosstalk:  -80dB or better at 1kHz and 10 kHz.

Controls: Rotary encoders: Volume (103 steps), Select Input.  Push Buttons: Power, Proc, Menu, Enter, Mono, Invert, Mute.

Power Supplies: Electronically regulated  low and high voltage supplies. Automatic 45 sec. warm-up/brown-out mute.  Line regulation better than .01%.

Noise:  1.7uV RMS residual IHF weighted balanced equivalent input noise with volume at 1 (109dB below 2V RMS output.)

Tube Complement: (6)-6H30P dual triodes, plus (1 each) 6550C and 6H30P in power supply.

Power Requirements:  100-135VAC 60Hz (200-270 VAC 50/60Hz) 130 watts. Standby: 2 watts.
