  • Nominal input level (for 20 dB headroom): -11.8 dBu (200 mV rms)

Line Input Specs (with Red-supplied TA3-XLR padded cables)

  • Input Impedance: 2000 ohm
  • Full scale input level: +19.4 dBu (7.2 V rms)
  • Nominal input level (for 20 dB headroom): -0.6 dBu (720 mV rms)

Line Inputs (with or without Red-supplied cable)

    • Frequency response:  flat, -2 dB @ 20 kHz, -2 dB @ 8 Hz, referenced to 1 kHz response (see graph)

    • THD+N: 0.01% (22 Hz-22 kHz BW) best case, input to output at +5 dBu input, padded cable (see graph)

When the inputs are driven without equal voltage on each leg of the connection (impedance-balanced sources), the THD+N starts increasing 6 dB sooner than when driven with equal voltages. The chart above shows the THD+noise with impedance-balanced sources. The chart below shows THD+noise driving both pin-2 and pin-3 with signal.
