ea azvorsieidte) ars
The STR-GX69ES or STR-GXSQES is a receiver which
controls audio and 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.
e A source direct switch is employed to reproduce high
fidelity sound.
Any source can be reproduced without passing through
the circuits of tone control and surround decoder.
Tuner
e Precise tuning is obtained thanks to the quartz-locked
digital synthesizer system.
e A total of 30 FM/AM stations can be preset in 3 memory
pages (A, B and C) that allow you to classify stations.
