Thông số kỹ thuật
Audio input
   Number/signal type : 6 stereo
   Connectors
      3.5 mm captive screw connectors. 5 pole
   Impedance : 25k ohms unbalanced. DC coupled
   Nominal level  +4 dBu (1.23 Vrms). -10 dBV (316 mVrms). configurable
   Maximum level            >+15 dBu. (balanced or unbalanced) at 1% THD+N
   Input gain adjustment  -18 dB to +24 dB. adjustable per input
    NOTE            0 dBu = 0.775 Vrms. 0 dBV = 1 Vrms. 0 dBV ≈ 2 dBu.
