m FEATURES
Dynamic balanced linear tracking tonearm employs
optical sensor and groove deflection angle detection
for extremely stable and accurate tracking.
The linear tracking tonearm moves across the record surface
in the same way as the cutter head used to make the record
in the first place.
Therefore there is virtually no tracking
error or skating force.
Located
by the
stylus
is an optical
sensor
that detects
tracking conditions
by means
of groove deflection angle.
Based on this information, tonearm movement is controlled
to maintain optimum tracking at all times.
A precision DC motor is used for tonearm drive to
assure quiet and accurate control.
Simple base operation. Completely automatic play.
Turn on the power, put on a record, close the top and press
the start switch.
After that, everything is handled by the
microcomputer
and
optical
sensor
which
automatically
detect record size, select correct speed and cue the tonearm
to the lead-in groove.
For non-standard
records, front panel speed selectors let
you select the correct speed manually (large 45s, or small
33-1/3 records, for example).
The
tonearm
automatically
returns
to the start position
after completing play.
The tonearm does not move if no
record is on the platter.
Complex operation also possible.
