CAUTION: Service of the STUDIO B Master-Room
should not be performed without proper test equipment or by other
than qualified personnel.
To dis-assemble the STUDIO B Master-Room for servicing, first remove
the power cord from the power source. Remove the screws holding the upper
cover. Remove only those screws on the lower cover which hold the cover
in place (pan head screws). Components and Test Points are now accessible.
WARNING: With the unit plugged in for testing, HIGH VOLTAGE is
present (power line) inside the chassis.
Test Point voltages may be determined with the Sound Column cable disconnected
from the chassis, provided pins 1 & 2 are jumpered.
CAUTION: If the Sound Column cable is disconnected at the sound
column only, insulate the connector pins with tape or other means
to prevent shorting. Any shorting of the pins can cause catastrophic
failure of transistors and IC's when the unit is powered.
CAUTION: The STUDIO B electronics unit must be operated with either
the remote control cable or the remote shorting plug installed.
Master-Room Sound Columns are hermetically sealed with no fieldserviceable
components inside. All repairs are performed at the factory only. If tests
indicate a defect ip the column, contact the factory or nearest MICMIX
dealer regarding replacement.
CAUTION: Attempts to dis-assemble a Sound Column will likely damage
internal components and will void the warranty.
