The initial setting at the factory is
“TUNER NORMAL”.
• If you find the sound is very
noisy while listening to the tuner
in the Hi-Fi mode, we recom-
mend you change to the
NORMAL mode.

If you press the DN button the

• How MaxTune SQ works its
magic
There are a variety of reasons, so
let’s get technical. 1) The FM
section has an extraordinarily high
80dB signal-to-noise ratio, thanks
to a new PLL (phase-locked loop)
circuit with low jitter, and a new
low-noise IF detection circuit. 2)
Lower distortion (typically 0.08%,
but always less than 0.1%) due to
an improved demodulation coil. 3)
High performance ceramic filter
with automatic Wide/Narrow mode
switching for greater selectivity,
important in crowded reception
areas. 4) Improved high-power
input characteristics. 5) The AM
section has new parts and circuitry
that are more resistant to
interference.
What all this adds up to is very
simple: a tuner capable of
delivering radio sound that doesn’t
suffer in comparison with CD
sound.
