Audio
   Gain Unbalanced output: -6 dB; balanced output: 0 dB (unity)
   Frequency response 20 Hz to 20 kHz, ±0.5 dB
   THD + Noise <0.5% @ 1 kHz at nominal level
   S/N >90 dB @ 20 Hz to 20 kHz
   Crosstalk <-65 dB @ 20 Hz to 20 kHz, <-80 dB @ 1 kHz and below 60 Hz, fully loaded
   Stereo channel separation >72 dB @ 20 Hz to 20 kHz
   CMRR >75 dB @ 20 Hz to 20 kHz
Audio input
   Number/signal type 4 stereo/mono, unbalanced (switchable)
1 mono, balanced/unbalanced aux-mix (always active, non-switchable)
   Connectors (5) 3.5 mm captive screw connectors, 3 pole
   Impedance >10k ohms unbalanced, >20k ohms balanced, DC coupled
   Nominal level -20 dBV (100 mV), -10 dBV (316 mV), 0dBu (0.775 V), or +4 dBu (1.23 V); (configurable)
    NOTE     0 dBu = 0.775 Vrms, 0 dBV = 1 Vrms, 0 dBV ≈ 2 dBu
+4 dBu and 0 dBu are professional audio line level standards.
-10 dBV and -20 dBV are semiprofessional, computer audio, and consumer audio standards.
   Maximum level +14 dBu, (balanced or unbalanced) at stated %THD+N
   Input gain adjustment –18 dB to +24 dB, adjustable per input (via RS-232/control software)
   Aux/Mix level adjustment -43 dB to +24 dB (adjustable only via front panel)
Audio output
   Number/signal type 1 stereo or mono, balanced/unbalanced
   Connectors (1) 3.5 mm captive screw connector, 5 pole
   Impedance 50 ohms unbalanced, 100 ohms balanced
   Gain error ±0.1 dB channel to channel
   Maximum level (Hi-Z) >+21 dBu, balanced or unbalanced at 1% THD+N
   Maximum level (600 ohm) >+15 dBm, balanced or unbalanced at 1% THD+N
    NOTE     An unbalanced-wired output results in a 6 dB attenuation.  A balanced-wired output has unity (0 dB) gain/attenuation.
