Connect the left channel’s
audio dc in
on the rear panel of the Nº30.5 to
the
left audio dc out
on the rear panel of the PLS-330; likewise, connect the
right channel’s
audio dc in
on the rear panel of the Nº30.5 to the
right au-
dio dc out
on the rear panel of the PLS-330.

COMMUNICATION PORTS
These communications ports allow the Nº30.5 to “link” to certain compat-
ible Mark Levinson components. (See “Linked Functions.”)
Linking connections
The Mark Levinson Linking system uses the Nº30.5 as the Master of (and
central clearinghouse for) inter-component communications. Other compo-
nents such as digital transports are connected to the Master as “Slaves,” and
can be “daisy-chained” using their Slave In and Slave Out jacks. As the ulti-
mate destination of all source signals, the Nº38 or Nº38S Preamplifier (if
owned)
must
be the final “Slave” in the chain. (
In technical terms, it termi-
nates the communications bus
.) In turn, the Nº38 can serve as a master to
an associated compatible Mark Levinson power amplifier—hence its “Mas-
ter” communications port.
Thus, if the only other Mark Levinson Link-compatible component you
have is the Nº38 or Nº38S, connect the Nº30.5’s
master
port to the
preamplifier’s
slave
port using a “straight-through” RJ-45 cable. If there are
additional Mark Levinson Link-compatible components in the system, place
the preamplifier at the end of the chain by connecting the last
slave out
port to the Nº38’s
slave
port. See the diagram below for clarification.
The RJ-45 cable needed for the Link connection between the Nº30.5 and
other Link components may be purchased from your Mark Levinson dealer.
It may also be easily and inexpensively made to length using two RJ-45
connectors and the appropriate length (up to 100 feet/30 meters) of RJ-45
(flat, eight conductor) cable.
RJ-45 cables and connectors are used throughout the world for both tele-
communications and computers, and are widely available at low cost. The
connectors are crimped on to the ends of the cable such that pin 1 at one
end is connected to pin 1 at the other end. Such a “straight-through” con-
nection is (counter-intuitively) made by introducing a 180
°
twist in the
cable between the two ends, as shown below.

Connecting the communication ports other than as
described in this manual will damage the Nº38 and the
associated Mark Levinson components, and will void those
