Notes:
1. Measured at 0 dB gain
2. +18 dBV input, 1 kHz
3. Unbalanced
4. “A” weighted noise floor
to maximum RMS
output
5. ISO™ input: Pins 1, 2
and 3 are transformer-
isolated. Shell is
connected to chassis/
AC mains ground. Pin
3 positive for positive-
going output at pin 3.
6. Pure resistive through-
out audio band
7. Within operating band
of each channel, this is
the minimum worst-
case level achieved
before clipping.
8. 0 dBu ³ 0.775 vrms
0 dBV = 1 vrms
