Audio

Gain	Adjustable
	When gain is set to unity (0 dB), balanced output from captive screw
	connectors or unbalanced output from RCA connectors will have a 0 dB
	gain; unbalanced output from captive screw connectors will be attenuated
	by 6 dB.
Frequency response	20 Hz to 20 kHz, ±0.5 dB
THD + Noise	<0.04% @ 1 kHz at nominal level
S/N	>90 dB at maximum output (unweighted)
