Nº32 Reference Preamplifier Basic Operation
Note
The master port is provided for possible future expansion and SHOULD
NOT be used when making Link connections. See “Linking” on page 4-
13 BEFORE attempting to link the Nº32 to other Mark Levinson
components.
IR input connector Accepts 5V infrared input signals with no more than 100mA of
current from standard infrared distribution equipment such as IR
repeaters. One 1/8-inch (3.5mm) mini-jack labeled IR input is avail-
able. The mini-jack requires a mini-plug (Tip/ Sleeve) connection in
which the tip of the mini-plug has positive polarity as shown below
in Figure 2-4.

Trigger input / trigger
output connectors
Provide trigger control. One 1/8-inch (3.5mm) mini-jack labeled
trigger input is available to accept 3-12V DC trigger signals from
associated components, and one 1/8-inch (3.5mm) mini-jack
labeled trigger output is available to pass these trigger signals to
associated components OR to send Nº32-generated 12 or 5V DC
trigger signals to associated components. Both mini-jacks require
mini-plug (Tip/Sleeve) connections.
If a component is connected to the trigger input connector, the
Nº32 passes the incoming trigger signal to the component
connected to the trigger output connector, creating a “daisy chain”
of trigger control. If no component is connected to the trigger input
connector, the Nº32 sends its own trigger signals to the component
connected to the trigger output connector. The Trig. parameter
configures the Nº32 to generate 12V level or 5V pulse trigger
signals.
Nº25/S DC power
connector
Provide DC power to the Nº25 or Nº25S Phono Preamplifiers. One
DC power connector labeled Nº25/S DC power is available. Use the
DC power cable supplied with the Nº25/S to connect the power
supply input on the Nº25/S to the Nº25/S DC power connector on
the Nº32.
ac mains connector Provides power to the Nº32 when the supplied power cord is
connected to the ac mains connector and an electrical outlet. One
IEC-standard AC mains receptacle labeled ac mains is available.
Note
Before operating the Nº32, make sure the ~ac mains connector label
indicates the correct operating voltage for the current location.
