| Frequency Response |
(Ref 1 kHz, channel controls centered)
50 Hz to 20 kHz 2 dB; -3 dB corner at 25 Hz |
| Voltage Gain |
(typical, controls full clockwise) |
| Total Harmonic Distortion |
(through 20 Hz-20 kHz filter; Input 1 and Master at 5, all other controls full counterclockwise) < 0.1% at +18 dBV output level, 50 Hz to 20 kHz |
| Hum and Noise |
(150 Ohm source; through 400 Hz-20 kHz filter)
Equivalent Input Noise: -125 dBV |
| Equivalent Input Hum and Noise |
(150 Ohm source; through 20 Hz-20 kHz filter)
-123 dBV |
| Output Hum and Noise |
(through 20 Hz-20 kHz filter; channel controls full counterclockwise)
- Master full counterclockwise: -90 dBV
- Master full clockwise: -70 dBV |
| Common Mode Rejection |
>70 dB at 1 kHz |
| Polarity |
Mic/Line, Send inputs to all outputs are non-inverting; Aux input to all outputs is inverting |
| Input Channel Activation |
Attack Time: 4 msec
Hold Time: 0.4 sec (switchable to 1.0 sec)
Decay Time: 0.5 sec |
| Off-Attenuation |
15 dB (switchable to ) |
| Overload and Shorting Protection |
Shorting outputs, even for prolonged periods, causes no dam age. Microphone inputs are not damaged by signals up to 3 V; Line and Monitor inputs by signals up to 20 V |
