Precautions
The STR-GX49ES is a receiver which controis audio/video
sources. The unit aiiows you to switch easiiy 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.

digital synthesizer system.

pages (A, B and C) that allow you to classify stations.
