Specifications

ASA 101
Audio
   NOTE  All audio specifications were tested with a stereo audio source, 50 ohm output impedance, and a sink with a 10k ohm load. Both left and right input channels were connected to the source at all times, even in tests where a signal was present at one input only.
  Gain  Generally unity gain with unbalanced output, +6 dB gain with balanced output. See the table below. Entries with an asterisk (*) indicate the input was set to no signal, but was still connected to the audio source.

  Frequency response  280 Hz to 20 kHz, ±0.5 dB, full frequency range THD+N <1%, with -10 dBV input
  THD + Noise  0.1% @ 1 kHz, <1% @ 280 Hz to 20 kHz
  S/N  130 dB at maximum output
  Stereo channel separation  >80 dB @ 1 kHz, >60 dB @ 20 kHz
Audio input
  Number/signal type  1 stereo, unbalanced
  Connectors  1 pair of male RCA (tip-ring)
  Impedance  300 ohms (with both input connectors connected to a stereo source)
  Nominal level  -10 dBV (316 mV)
  Maximum level  +7 dBV (2.2 V) @ 1 kHz, (unbalanced) at <1% THD+N
   NOTE  0 dBu = 0.775 Vrms, 0 dBV = 1 Vrms, 0 dBV ≈ 2 dBu
Audio output
  Number/signal type  1 mono, balanced/unbalanced
  Connectors  (1) 3.5 mm direct insertion captive screw connector, 3 pole
