Notes
(Unless otherwise specified measurements are at unity gain with +16 dBu signal.
1
Unity gain, SMPTE 4:1, 60 Hz & 7 kHz sine waves.
2
Unity gain, DIM30 4:1, 3.15 kHz SQ wave & 15 kHz sine wave, 30 kHz LPF.
3
Power spectral density.
4 Group Delay inherent in conversion process. WST= 1 /
48 kHz
5 20 dB pad engaged.
6
Maximum levels are differential and balanced. Limit set by protection circuit.
7
Relative to unity gain, 1 kHz.
8
Electronically balanced, RF surpressed, differential impedance 20- 20kHz.
