Operating instructions

BTX Shadow Synchronizer
Figure A-2 illustrates the necessary cable for connecting the BTX Shadow
Synchronizer with to the MTR-90III. The Capstan Speed Control Range of the
Shadow must be adjusted for a range of 50% to 200% of normal play speed.
Use the "speed %" display on the CB-147 Remote Control Unit to assist in
this adjustment. Refer to the BTX Shadow Synchronizer operation manual for
further details.
