1. FIVE BAND PROGRAM EQUALIZER
Five separate controls allow great flexibility
when compensating for program deficiencies.
2. "LED" POWER OUTPUT INDICATORS
Two columns of seven yellow "LED" indicators
provide an indication of the amount of power being fed to your speakers.
3. POWER GUARD INDICATOR AND
PROTECTION CIRCUIT
Two red "LED" power guard indicators indicate
when the power amplifier has reached full output.
At this point the power guard circuit begins to
control amplification dynamically so that you will
not hear the harsh distorted sound of square
wave clipping. In addition your speakers are protected from burnout.
4. ELECTRONIC AUDIO SIGNAL SWITCHING
FET analog switches are used to give smooth swit-
ching transition from one input to another without
clicks and pops.
5. SUPER-TRACKING VOLUME CONTROL
The volume control is a precision stepped at-
tenuator which has left to right tracking accuracy
within 1 dB throughout its entire range. System
balance is maintained at all listening levels.
6. LESS THAN 0.05% TOTAL
HARMONIC DISTORTION
Harmonic distortion does not exceed 0.05% when
measured from the phono input to the speaker
output from 20 Hz to 20 kHz at all power levels
from 250 mW to full rated output.
7. TRUE VARIABLE LOUDNESS
COMPENSATION CONTROL
The loudness control operates independently of
the volume control and its contour is accurately
modeled after the Fletcher Munson family of
"equal loudness" curves.
8. DUAL TAPE MONITOR AND
TAPE COPY SWITCHES
Two tape recorders can record simultaneously
from the program being listened to or you may
record from one to the other without interfering
with the "Listen" program.
