6 DC trigger in and out
On a simpler level than PHAST, AMX, or Crestron, some systems
control whether a given component is on or off (actually, operat-
ing or in standby) by means of a simple control voltage.
If the appropriate 3-12V level “trigger” signal arrives at the trig-
ger input
of the Nº32, it turns on. When the Nº32 turns on, it
passes along a trigger signal to another component (say, a power
amplifier). In this way, it is possible (if you like) to set up a “daisy
chain” of components that can be controlled by one another (at
least to some degree.)
The Nº32 can produce and send from its trigger output either a
5V pulse (such as a momentary contact switch might make) or a
12V level signal (where the presence of 12V forces the unit out of
standby, and its absence forces it into standby).
7 Nº25/S power port
This port provides DC power in a plug-compatible format suit-
able for use with Mark Levison Nº25 and Nº25S outboard phono
preamplifiers, for people who wish to continue using their older
phono preamps. Connect the DC cable that came with your Nº25/
S to this power port rather than to the PLS-226 you would have
been using previously.
8 AC mains receptacle
This IEC-standard AC mains receptacle is used with the remov-
able AC power cord to supply the Nº32 Controller with power.
Warning! Prior to connection to the AC mains, please check the
voltage label on the rear panel of the Controller to
ensure that your unit conforms to the power supply in
your area.
Following the guidelines in the Quick Start section of this manual,
connect the power cord to this receptacle and the AC mains outlet
in the wall.
When power is first applied to the Nº32, the preamp will run
through an automatic initialization sequence which displays a
software identification code, and then enters standby.
