OTARI MX-5050 BIII-2 - 2.5 Power Connection

2.5 Power Connection
Confirm that the power voltage marked on the rear panel corresponds with the line voltage
being used.
Turning on the machine
For power connection, use the included Power Cable. Connect the Power Cable plug to
the power connector located at the rear of the machine. Make sure that the machine is
turned off before connecting the other end of the power cable to the AC line outlet. The
machine is now ready to be turned on.
Pressing the upper portion of the POWER Switch applies power to the machine. After
power is applied to the machine, the VU meters, tape timer digits, and the indicator
above the STOP button will illuminate. The Tape Timer will show the selected tape speed
for several seconds after the machine is turned on, and then will change to tape time
indication.
Turning on the machine while pressing the STOP button will cause the ROM version of the
CONTROL PCB Assembly to be displayed.
AC Voltage Connector Replacement
When the AC Line Voltage is different from the factory setting, the Line Voltage connector
should be changed to the proper one. In this case, contact Otari or nearest Otari dealer
and order the proper Line Voltage connector. The Line Voltage connector (white) is located
beside the Supply Reel Motor. First remove the rear panel and replace it. The following
figure describes the wiring of the connectors.
