High Performance Direct-Dive in Slim Design
The SL-DL1
is divided into upper and lower cabinet halves. The tophalf, which also
functions as the dust cover, contains the linear tracking tonearm, its drive
mechanism and optical sensor. The lower cabinet contains the tonearm servo
control system (microcomputer) and Technics original integral rotor-platter
direct drive motor.
Simple basic 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 amicrocomputer and optical sensor which
automatically detect record size, select correct speed and cue the tonearm to
the lead-in groove.
For
non-standard record, front panel speed selectors let you select the correct
speed manually (large 45s, or small 33⅓ records ). 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
Although
easy operation is a basic feature of this unit, complex functions are also
possible. The "search" function allows start, stop switches
controlled inward and outward movement of the tonearm at slow and fast speed,
plus fine control in approximately 1 mm steps.
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 ofgroove 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
