The specifications for this IR input call for a triggering voltage of 5-12 volts
at no more than 100 milliamperes of current, with the tip of the
plug having positive polarity , as below:
If you would like more information on the possibility of using an infrared
repeater with your Nº39, please contact your Mark Levinson dealer.
7 COMMUNICATION PORTS
These communications ports allow the Nº39 to "link" to certain compatible
Mark Levinson components. (See "Special Functions.")
The Mark Levinson Linking system provides for inter-component communi-
cations. Normally , the digital processor in the system would serve as the
"master" of this communications system, while other components including
the transport would be "slaves" to that master. (The master acts as a central
clearinghouse for that information—sort of like the Post Office, but quite a
bit faster.) Since the Nº39 is both a digital transport and a digital processor
in one component, it automatically configures itself as either a master or a
slave, based on the needs of the rest of the system. (Technically, if the Nº39
senses another master on the communications bus, it automatically config-
ures itself as a slave.)
The most common configuration for systems incorporating the Nº39 is illus-
trated at left. The Nº39's
the chain, and is connected to the
fier using a "straight-through" eight conductor modular cable. The preampli-
fier, in turn, serves as the "master" for the power amplifier(s) with which it
is used. (See diagram at left for clarification.)
Alternatively, if you elect to use the variable output feature of the Nº39 to
drive a power amplifier directly , it may serve as the power amplifier's "mas-
ter" using a special eight-to-six conductor Link cable described below. Us-
ing this cable automatically configures the Nº39 as though it were a Mark
Levinson preamplifier in order to control the Mark Levinson power ampli-
fier. (See diagram at left for clarification.)
Finally, if at some point you end up using your Nº39 as a transport in con-
junction with a separate Mark Levinson digital processor, simply insert it
between the processor and the preamplifier (connecting the processor's
master port to the Nº39's
preamplifier's slave
"master" on the communications bus, the Nº39 will automatically configure
itself as a slave to that master (hence the
on the rear panel jack). (See illustration on next page for clarification.)
