Troubleshooting & Maintaining
No Link Controls
1. Make sure the slave chain includes Mark Levinson digital audio
processors and digital transports that are compatible with the
Nº32.
2. Make sure Link connections have been made using Link com-
munication ports and Link cables.
3. Examine Link connections to ensure a solid connection
between linked components. Constructed Link cables must be
twisted 180° for a straight-through (pin 1-to-pin 1) connection.
4. Examine the slave chain to ensure that linked components are
connected in the proper sequence.
5. Make sure Link controls have been enabled on the linked digital
transport(s) linking menu, which allows activation and deacti-
vation of individual Link controls. Refer to the appropriate digi-
tal transport owner’s manual for additional information.
6. Make sure linked components have been powered on in the
proper order – digital transport(s), then digital audio processor,
then Nº32, then power amplifier(s). Linked components must
be powered on ONE AT A TIME in this order to ensure proper
functioning of Link controls.
Audible Hum
1. If a cable TV connection is present, disconnect the cable from
the electrical outlet. If this eliminates the humming sound, a
ground loop isolation device is required. Contact an authorized
Mark Levinson dealer for assistance.
2. Disconnect components one at a time to isolate the problem.
Once the problem is identified, make sure the problematic com-
ponent is properly grounded and connected to the same electri-
cal circuit as the Nº32.
