Crown psl-2 Guía De Instalación Rápida
INTRODUCTION
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.

SONIC PERFORMANCE
Signal-to-Noise:
(A-weighted) 103 dB below rated output for all inputs ex-
cept Phono. 93 dB below rated 10 mV phono input.
cept Phono. 93 dB below rated 10 mV phono input.
Total Harmonic Distortion (THD):
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.
Less than 0.0009% at 1 kHz with IHF load. Phono: Less
than 0.009% from 20 Hz to 20 kHz.
Intermodulation Distortion (IMD):
(60 Hz and 7 kHz 4:1) Less than 0.0025% at rated output.
Phono: Less than 0.0025% at rated output.
Phono: Less than 0.0025% at rated output.
Phono Gain:
Adjustable 30 to 50 dB (33 to 330 mV for rated output).
Low Filter:
18 dB per octave slope, down 32 dB at 10 Hz.
Loudness Compensation:
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.

Muting:
Seven second turn-on delay during which the outputs are
shorted to prevent turn-on transients from reaching the
speakers.
