4. Take the linked preamplifier out of standby.
•All linked power amplifiers should come out of standby as
well. If this does not occur, repeat steps 3 and 4. If problems
persist, contact Mark Levinson Customer Service at 781-
280-0300 or www.marklevinson.com.
Link Controls Linking Mark Levinson components allows them to share certain
controls. The table below provides a general description of
controls the Nº432/431 shares with other linked components.
Some controls may not be available for certain component
combinations. Other Mark Levinson components may share
additional controls. Refer to the appropriate documentation for
additional information.
Note the following:
• Linked components must be powered on ONE AT A TIME in
the specific order listed in step 3 (previous page) to ensure
proper functioning of Link controls.
•Link controls must be enabled on the linked digital transport
linking menu, which allows activation and deactivation of
individual Link controls. Refer to the appropriate digital
transport owner’s manual for additional information.
• Some Mark Levinson digital transports accommodate a maximum
of four front panel display characters. In these cases, certain
input names appear abbreviated on the front panel display.
For example, an input named No320S will appear as No32 on
the digital transport front panel display even though the
input is associated with the Nº 320S.
• The linked preamplifier and power amplifier(s) must be in the
same standby-state to allow the linked power amplifier(s) to
enter standby after a power failure.
Standby Link
Fault Condition
Link
Placing the linked preamplifier into standby
also places all other linked power amplifiers
into standby. Taking the linked preamplifier
out of standby also takes all other linked power
amplifiers out of standby.
If a linked power amplifier experiences a fault condition,
it will report the fault condition to the linked preamplifier.
If this occurs, the power amplifier number and fault
condition code will appear on the preamplifier’s front
panel display.
The power amplifier number refers to its position in the
slave chain. For example, AMP1 refers to the first power
amplifier in the slave chain. Power amplifier fault
condition codes are described in the table to the right.
Refer to “Extensive Protection” for additional information
about fault conditions.
Placing a linked power amplifier into standby
also places all other linked power amplifiers
into standby. Taking a linked power amplifier
out of standby also takes all other linked power
amplifiers out of standby.
