Speaker Placement - Sony SS-G5D Owner's Instruction Manual

SPEAKER IMPEDANCE
The SS-G5D has nominal input impedance of 8 ohms, and will
perform equally well with any amplifiers. If your amplifier has
transformer outputs of 4, 8 and 16 ohms, connect the speaker
to the 8-ohm terminals.
CONNECTION TO THE AMPLIFIER
Notes
e Make sure that none of the strands is separated from its group
of the wire and shorts across the speaker or amplifier terminals.
e Make sure the connections of phasing (® and © terminals)
and left and right channels are correctly made between speaker
and amplifier. If the phase is reversed, the bass tones seem to
be missing and the position of the instruments becomes obscure.

LEVEL ADJUSTMENT
In accordance with your personal preference and the room acous-
tics, the tweeter and mid-range levels can be adjusted by the
controls for each unit. At the NORMAL position, the typical
response can be obtained. Clockwise rotation will increase the
response, and counterclockwise rotation will decrease the res-
ponse. The tweeter response can be changed from +2dB to
— 48 dB, and the mid-range response can be changed from +2 dB
to —4 dB.
Before adjusting these levels, be sure to cancel the tone controls
of the amplifier so that the amplifier provides a flat frequency
response, and set the volume control to your ordinary listening
level.

SPEAKER PLACEMENT
The speaker characteristics is greatly effected by the room acous-
tics and the speaker placement. 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,
which reduce the stereo effect.
Corner locations emphasize the bass tones. If there is "boomy"
distortion, place the speakers apart from the corners, and on the
bricks or concrete blocks with the proper thickness.
Place the left and right speakers separated by an amount slightly
less than the distance from the listening area to each speaker.
Proper distance between the two speakers is important to obtain
the best stereo effect. See the illustration.
If the speaker separation is too wide, the unnatural "hole-in-the-
middle" effect occurs, reducing tone quality. In this case face
the speakers a little inward torward the listening position.
