(Weighted background noise to peak signal ratio) 110dB.
50k-ohms
Designed to feed recorder and preamp
inputs of 5k-ohms or greater.
7 volts rms at 1kHz into a 5k-ohm load,
30dB for tape recorders with signal to noise ratios of 45dB or better.
40dB for dbx encoded discs (A weighted).
2:1 constant linear decibel.
+1dB per 20dB for complete encode-decode cycle.
+0.5dB 50Hz to 15kHz; +1dB 30Hz to 20kHz (single sine-wave encode-decode cycle).
40.25dB 30Hz to 20kHz (for complex music program).
—3dB at 20Hz (for tape noise reduction).
—3dB at 27kHz (for disc decode mode).
2nd Harmonic:
less than or equal to 0.1% encode-decode from 30Hz to 15kHz.
3rd Harmonic:
less than or equal to 0.1% encode-decode from 100Hz to 15kHz.
3rd Harmonic:
less than or equal to 0.5% encode-decode from 30Hz to 100Hz.
0.15% typical; 0.3% maximum for encode/decode cycle. (GOHz & 7kHz 4:1 SMPTE)
Risetime: less than 20 microseconds
Overshoot:
12dB for 1kHz tone burst
Release rate: 240dB/second
100mV
to 3V for unity gain; adjustable for convenience
in level setting and avoidance
of overload in succeeding audio stages; level match setting unimportant
for encode-
decode tracking.
NOTE:
Above measurements at 1 volt rms input and output.
