3. Turn on the SQA-2030 and the front amplifier.
4. Select your desired program source as follows:
@For a record, tuner, or auxiliary source connected to the front
amplifier
Set the SQA-2030 MONITOR switch to SOURCE and set the
front amplifier input selector to the desired input program.
@Two-channel tape
Set the SQA-2030 MONITOR switch to TAPE.
@Four-channel tape or other discrete program source
Depress the DISCRETE button.
5, Play the program. When playing records, tuners, auxiliary
sources, or two-channel tapes, select the desired reproduction
system as follows:
@For any SQ program, depress the SQ button.
@ For any other matrix four-channel program, depress the R-MTX
button.
@ For reproducing stereo programs in two-channel sound, depress
the 2 CH button. To listen to them in simulated four-channel
sound, use either SQ, R-MTX or 2—4 as you prefer.
6. Adjust the MASTER VOLUME to the desired level. Adjust the
four-channel tone with the front amplifier tone controls, and
the back-channel tone with the SQA-2030 BACK TONE con-
trols. Use the SQA-2030 LOUDNESS switch if you wish.
LEVEL ADJUST (TAPE) switch (on the rear panel) adjustment :
This switch adjusts the TAPE input (REC/PB input) sensitivity ;
move the switch to either NORMAL or LOW depending on which
position provides the same volume as that of the test record.
If the tape sound is distorted during SQ, R-MTX or 2-4 repro-
duction, the tape input level is too high. In this event, set the
switch at NORMAL.
To play discrete four-channel records, a special cartridge and an
adaptor must be added. If you have these components, connect
the outputs of the discrete four-channe! adaptor to the SQA-2030
DISCRETE INPUTs.

Tape Recording
Two-channel tape recording: While reproducing phono, fm or
auxiliary programs, the signal fed to the FRONT PREAMP INPUT
jacks always goes directly to the 2 CH TAPE RECORDER REC
OUT jacks (REC/PB output) without being decoded. Therefore,
any SQ program can be recorded as an SOQ tape. The LEVEL
ADJUST (INPUT) switch has no effect on the recording results.
Recording Monitor
When using a three-head tape recorder, instantaneous tape/
source comparison is possible through the speakers by setting
the SQA-2030 MONITOR switch alternately to SOURCE (sound
from source is heard) and to TAPE (sound from tape an instant
after it has been recorded is heard). In this event keep the tape
recorder monitor switch at TAPE.
