Sony SAVA-57 - Choosing the Best Location

8
You can place the transmitter on a television, a
bookshelf, etc., or you can hang it on a wall.
Hanging the transmitter on the wall
When the front speakers are powered on, power is
supplied to the transmitter, which emits a signal. When
the active rear speaker receives the signal, the receptor
lights green. If the receptor stays red, adjust the
position and angle of the transmitter until it goes
green.
Caution regarding rear speaker placement
Placing the active rear speaker near a light bulb or in direct
sunlight may cause noise from the speakers.
Caution
There may be interference if you operate this system at the
same time as other infrared remote control equipment. If
interference occurs, avoid using the two systems
simultaneously.
Notes
• The infrared ray will not penetrate walls or opaque glass.
Therefore, the transmitter must be placed “in sight” of the
active rear speaker.
• Placing the transmitter too far away from the active rear
speaker may cause noise.
• Since the signal output to the rear speakers is monaural,
you can switch the active and passive speaker positions
from left to right without reversing the balance.
• After operating continuously for a long time the surface of
the transmitter may become hot. This is not a
malfunction.
Getting Started
Choosing the Best Location
To obtain high sound quality and a proper sound
image from the front speakers, place the speaker with
the built–in operation panel to the left of your TV and
the other to the right of your TV so that the center
channel speaker angle towards the center of the room.
Front speakers
For the best central sound image, place the left and
right speakers within 2.5 m (8 ft) of each other and
equidistant from the TV.
Rear speakers and transmitter
Place the rear speakers so that they fire directly across
at each other about 60 to 90 cm (2 to 3 ft) above the
listener’s ear.
The rear speaker system has an infrared receptor to
receive signals from the supplied transmitter.
The infrared receptor is located on the active rear
speaker only.
The following diagram illustrates the approximate
effective area of the infrared ray emitted from the
transmitter.
