Speaker Location
In many home-entertainment stereo systems, the choice of
speaker location is often limited by the existing furniture arrange-
ment. However, if rearrangement is possible, or if you want
to furnish the area specifically for stereo listening, here are a
few suggestions for optimizing your listening pleasure.
Set up your speakers in a large room having carpeting on the
floor. If the room has heavy draperies, so much the better.
Carpets, draperies, and upholstered furniture minimize the
multiple reflections of high-frequency sound that occur in a bare
room and which reduce the stereo effect.
Four-channel speaker placement is not especially critical. But
for optimum acoustical effect we recommend you place the four
speakers in a square or rectangular area having a maximum
short-side to long-side ratio of approximately 1: 1.5. When
arranging the speakers in a rectangle, use the short-side for
right and left channels, and the long-side for front and back
channels.
Position the left and right speakers in similar acoustic environ-
ments. If you set up the left and right speakers in an un-
balanced acoustic condition, i.e. positioning the left speaker in
a corner and the right speaker in the middle of a wall, you will
produce unbalanced bass—the left channel sound will be em-
phasized in this case since corner locations emphasize the bass
tones.
If you must position the speakers off the floor, do not place
them higher than eye-level. Because of psychological condi-
tioning, sound coming from the vicinity of the ceiling gives an
unnatural feeling.
Connections: Carefully connect the four speakers to the res-
pective SPEAKER terminals of the front amplifier and the SQA-
2030 ; left front speaker to left front terminals etc. and @ to
®, © to ©. For simplifying the @ and © terminal connections

BACK SPEAKER
CAUTION
@Do not connect the speaker terminals of one channel together
with those of the other channel.
e@The SQA-2030 delivers 32 watts (per channel) of dynamic
power into each 8-ohm speaker. Be sure to use speakers
with suitable power handling capabilities. tf low wattage
speakers are to be used, reduce the volume when removing
the phonograph pickup from a record or when tuning across
the fm band. Speaker damage may result if this precaution is
not observed.
Front Amplifier
Connect the recording outputs of the front amplifier to the
SQA-2030 FRONT PREAMP INPUT jacks. Connect the tape
inputs of the front amplifier to the FRONT PREAMP OUTPUT
jacks. The input level can be changed in three steps with the
associated LEVEL ADJUST (INPUT) switch (refer to page 8).
Record Player, Tuner and Auxiliary Sound Sources
Connect these sources to the front amplifier as usual. SQ records,
conventional two-channel records, off-the-air programs and
auxiliary sources are played through these connections.
Two-channel Tape Recorder
For tape playback, connect the line outputs of the tape recorder
to the SQA-2030 2 CH TAPE RECORDER TAPE inputs. For tape
recording, connect the line inputs of the tape recorder to the
2 CH TAPE RECORDER REC OUT jacks. The tape input level can
be changed by the associated LEVEL ADJUST (TAPE) switch
(refer to page 10).
If your tape recorder has the same type DIN 5-pin connector as
that on the SQA-2030 (indicated REC/PB), the record and
playback connections are made with a single 5-pin cable, such
as the Sony Connecting Cord RC-2 (optional). When using this
DIN connector, do not use the 2 CH TAPE RECORDER TAPE
inputs and REC OUTputs. :
Discrete Four-channel Tape Recorder
Connect the front line outputs of the tape recorder to the SQA-
2030 DISCRETE FRONT INPUTs, and the back line outputs of
the recorder to the DISCRETE BACK INPUTs. Check the con-
nections of the left and right channels—left outputs to left
inputs, and right outputs to right inputs.
Power Connections
Before making any form of power connection, make sure the
POWER switch is set to OFF. Then plug the SQA-2030 line
cord into a convenient 120V ac 60 Hz electrical outlet.
The UNSWITCHED AC OUTLET on the rear panel prowides a
convenient source of ac power (300 watts maximum) for any
other system components. Equipment plugged into this outlet
must have its own power switch.
