Polarity	Positive or negative (follows input)

Audio

Gain	+0 dBu unbalanced, +6 dBu balanced
Frequency response	20 Hz to 20 kHz, ±0.05 dB
THD + Noise	<0.03% @ 1 kHz at nominal level
S/N	>90 dB at rated maximum output (+21 dBu)
Crosstalk	<-80 dB @ 1 kHz, fully loaded
Stereo channel separation	>90 dB @ 1 kHz
CMRR	>75 dB @ 20 Hz to 20 kHz

Audio input

Number/signal type	6 stereo, balanced/unbalanced (rear panel)
	1 stereo, unbalanced (front panel)
Connectors	(6) 3.5 mm captive screw connectors, 5 pole, and
	(1) 3.5 mm mini stereo jack (unbalanced), or
	2 RCA female (white = L, red = R)
