| Audio |
|---|
| Gain | Unbalanced output: -6 dB; balanced output: 0 dB,
when input gain is set to 0 dB, output volume is at 100, and the input and output are set to the same level via the Line Level DIP switch |
| Frequency response | 20 Hz to 20 kHz, ±0.05 dB |
| THD + Noise | 0.03% @ 1 kHz at nominal level |
| S/N | >90 dB, balanced at maximum output (unweighted) |
| Crosstalk | <-120 dB @ 1 kHz |
| Stereo channel separation | >80 dB @ 1 kHz, >60 dB @ 20 kHz |
| CMRR | >75 dB @ 1 kHz |
| Volume control range | -100 dB to 0 dB (volume numbers 0 through 100) in 0.5 dB steps |
| NOTE | Attenuation = volume number minus 100. The default is -30 dB = volume number 70. |
|
| Bass control range | ±14 dB, 100 Hz referenced to 1 kHz (0 through 14) in 2 dB steps |
| NOTE | Bass dB = (bass number minus 7) times 2. The default is 0 dB = bass number 7. |
|
| Treble control range | ±14 dB, 10 kHz referenced to 1 kHz (0 through 14) in 2 dB steps |
| NOTE | Treble dB = (treble number minus 7) times 2. The default is 0 dB = treble number 7. |
|
|
| Audio input |
|---|
| Number/signal type | 4 channels, which can be mono or tied into stereo pairs, balanced/unbalanced |
| Connectors | (2) 3.5 mm captive screw connectors, 5 pole |
| Impedance | >18k ohms unbalanced/balanced, DC coupled |
| Nominal level | +4 dBu (1.23 V), -10 dBV (316 mV), switchable per group |
| Maximum level | +20 dBu (7.75 V), (balanced or unbalanced) at 1% THD+N |
| Input gain adjustment | -12 dB to +12 dB |
| NOTE | 0 dBu = 0.775 Vrms, 0 dBV = 1 Vrms, 0 dBV ≈ 2 dBu |
