Crown PSL-2 Quick Reference

Professional Preamplifier Quick Reference
®
NORMAL
POWER 1 TAPE 2
The Crown PSL-2 is a professional stereo preamplifier,
bringing all system components together in a single ver-
satile control unit. "Straight-Line" signal path engineering
results in very low distortion.
(A-weighted) 103 dB below rated output for all inputs ex-
cept Phono. 93 dB below rated 10 mV phono input.
Less than 0.009% from 20 Hz to 20 kHz at rated output.
Less than 0.0009% at 1 kHz with IHF load. Phono: Less
than 0.009% from 20 Hz to 20 kHz.
(60 Hz and 7 kHz 4:1) Less than 0.0025% at rated output.
Phono: Less than 0.0025% at rated output.
Adjustable 30 to 50 dB (33 to 330 mV for rated output).
18 dB per octave slope, down 32 dB at 10 Hz.
Bass compensation matched to ISO curves (Robinson-
Dadson) down to 60 phons; tracked to Level (gain) con-
trol with active network to eliminate unwanted subsonic
boost.
Seven second turn-on delay during which the outputs are
shorted to prevent turn-on transients from reaching the
speakers.
Tape, Tuner, CD and Aux 25 kohms; phono 47 kohms in
parallel with less than 50pF.
250mV applied to Tape, Tuner, CD or Aux input yields full
rated output at full gain of 20 dB.
600 ohms.
Main and phono outputs: 2.5 volts
