Audio Research REF 6 SE

Specifications:

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).
