Stereo Preamplifier Audio Research ARC REF 6/ REF6

SPESIFICATION FREQUENCY RESPONSE
+0-3dB, 0.4Hz 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 BAL


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


18V RMS BAL, 9V RMS SE.


RATED OUTPUTS


2V RMS (1V RMS SE) into 200K ohm balanced load (maximum balanced output capability


is 70V RMS at less than 0.5% THD at 1kHz).


CROSSTALK


-88dB or better at 1kHz and 10 kHz.


CONTROLS


Rotary encoders: Volume (103 steps), Select Input. Push Buttons: Power, 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
