Description: Rack-mount digital audio processor using predictive delta modulation with compansion (CPDM). Output: conventional TV signal (North American standards) which can be recorded on any high-quality VCR. Power consumption: 60W. Dynamic range: 110dB (maximum 1kHz signal to A-weighted noise 20Hz–20kHz), 105dB (unweighted). Frequency response (sinewave 100mV input): 20Hz–20kHz ±0.5dB. THD (1V input, 1kHz): 0.05%. Wow & flutter: <l0.01% (unweighted), 0.006% (weighted RMS). Anti-aliasing filtration: –3dB at 37kHz. Sampling/bit rate: 644kHz. Maximum input/output levels: 24dBm. Mike preamp (optional): adds less than 1dB of noise for mikes between 100 and 1k impedance. Inputs: line 5k ohms, differential; edit audio 20k ohms, differential; mike 100k ohms, 6.8k ohms if phantom-powered (48V); video & sync 75 ohms. Outputs: line 47 ohms, single-ended, drives 600 ohms, switchable to balanced; edit audio 100 ohms, single-ended; headphones 150 ohms.
