INTRODUCTION
The
Quad
FM4 is
a self
powered
stereo
tuner covering the FM band
(88
-
108
MHz) only and designed
to
be used
in
conjunction
with
Quad
and
similar high
quality pre.amplifiers.
The entire operation of the
tuner is
controlled by a
microprocessor
so
that
the only controls on the
tuner
are an on/off switch,
tuning knob, and
preselector
buttons.
Up to seven stations can be stored
in
the tunef s
memory
and
recalled
at
the touch of a button.
Manual tuning
is
accomplished
in the normal manner in the sense that the
tuning
knob is turned
clockwise
to move
up
the frequency band and vice
versa. The frequency tuned
is
displayed digitally and a bar
graph gives
simultaneous
indication of
signal
strength and
centre
channel tuning.
