5.2 OUTPUTS
Connector: 3 pin XLR male
Type: electronic servo balanced (unbalanced without 6dB loss)
Impedance: 65 ohms bal or unbal (nominal load 600 ohms or greater)
Max level out (bal): +25dBu(ref = +4), +10.8dBV(ref = -10)
Max level out (unbal): +20dBu(ref = +4), +10.8dBV(ref = -10)
5.3 AUDIO
Frequency response: +/- 1dB 10Hz to 65KHz
Hum & noise: measured for a 1KHz tone at unity gain
No gain reduction: -67dBu(ref = +4), -86dBV(ref = -10)
10dB gain reduction: -74dBu(ref = +4), -89dBV(ref = -10)
Crosstalk @ 20KHz: -65dBu(ref = +4), -78dBV(ref = -10)
Dynamic THD typically .05% for 1KHz at 20dB gain reduction
Static THD: .025% at maximum output level
IMD, max output: .13%(ref = +4), .4%(ref = -10)
