Precautions. J - Sony STR-GX49ES Operating Instructions Manual

Precautions
The STR-GX49ES is a receiver which controls audio/video
sources. The unit allows you to switch easily among a
variety of audio/video programs.
Amplifier
• Optical Legato Linear A System allows the receiver to
operate automatically as a class A amplifier when the
level is low and as a class B amplifier when the level is
high without disturbing the sound signal. This minimizes
total harmonic distortion at every sound stage.
• These receivers have a spontaneous twin drive power
circuit. Condensers having large capacity are used
independently for the voltage amplification drive stage
of class A and power output stage of class B. Thus, a
stable output and high quality sound are obtained,
resulting in exclusion of power interferences.
The class A stage realizes a stable operation free from
interference of the power stage even when an
instantaneous or strong output is received.
• A source direct switch is employed to reproduce high
fidelity sound.
Any source can be reproduced without passing through
the circuits of tone control, loudness switch and balance
control.
Tuner
• Precise tuning is obtained thanks to the quartz-locked
digital synthesizer system.
• A total of 30 FM/AM stations can be preset in 3 memory
pages (A, B and C) that allow you to classify stations.
Remote commander
• The remote commander allows you to control most of
Sony's audio equipment from a distance.
On safety
• Operate the unit only on 120 V AC, 60 Hz.
• Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified
personnel before operating it any further.
• Unplug the unit from the wall outlet if it is not to be used
for an extended period of time. To disconnect the cord,
pull it out by grasping the plug. Never pull the cord
itself.
• One blade of the plug is wider than the other for the
purpose of safety and will fit into the power outlet only
one way. If you are unable to insert the plug fully into the
outlet, contact your dealer.
On operation
• Before making program source connections, be sure to
turn the power switch off and unplug the unit.
m
When the unit is not used, turn the power off, to
conserve energy and to extend the useful life of your
unit.
On cleaning the cabinet
Clean the cabinet, panel and controls with a soft cloth
lightly moistened with mild detergent solution. Do not use
any type of abrasive pad, scouring powder, or solvent such
as alcohol or benzine.
