Captive screw input	81x (38 dB)
CMRR	75 dB (typical) @ 1 kHz
Bass adjustment	±10 dB @ 100 Hz
Treble adjustment	±10 dB @ 10 kHz

Audio input

Number/signal type	1 stereo/mono, balanced/unbalanced input
	2 stereo/mono, unbalanced inputs
	(The three inputs are individually buffered and mixed together. Stereo signals
	are actively summed into a mono signal.)
Connectors	(1) 3.5 mm captive screw connector, 5 pole (main input)

(1)3.5 mm mini audio jack (tip, ring, sleeve)

1 pair RCA

Impedance	>10k ohms balanced/unbalanced, DC coupled
Maximum level	+20 dBu (balanced, captive screw) or +4 dBV (unbalanced, RCA/TRS) at
	1% THD+N
Input sensitivity
RCA and TRS inputs	-10 dBV if driven by one input
	-16 dBV if both inputs are summed
Captive screw input	+4 dBu if driven by one input
	-2 dBu if both inputs are summed

NOTE: 0 dBu = 0.775 Vrms, 0 dBV = 1 Vrms, 0 dBV ≈ 2 dBu
