Building a Link cable

PRECAUTION

Using a turntable

Tip polarity for External IR input

The RJ-45 cable needed for the Link connection between source components and the preamplifier 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 telecommun-ications 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” connection is (counter- intuitively) made by introducing a 180° twist in the cable between the two ends, as shown below.

The power amplifier Link connection is made using a 6-conductor Link cable. Connect the Nº38’s master port to the slave port of a compatible Mark Levinson power amplifier.

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 products’ warranties.

6INPUTS 3-6

Accepts right-channel and left-channel (single-ended) inputs from line-level source equipment such as tuners, CD players, and tape decks.

If a turntable is to be used with the Nº38, it must be used in conjunction with a phono preamp such as the Mark Levinson Nº25 which will handle RIAA equalization and which will deliver a line- level signal to the input of the Nº38.

7EXTERNAL IR INPUT

The Nº38 incorporates an infrared repeater input to facilitate a wide range of installation options. If desired, the Nº38 may be placed inside a cabinet or outside the normal line-of-sight in the listening area, with the controlling IR signal being relayed to the Nº38 by any of a number of commercially-available IR repeaters.

The specifications for this IR input call for a triggering voltage of

5 volts at no more than 100 milliamps of current, with the tip of the

1⁄8" mini-plug having positive polarity, as below:

–+

5 volts @ less than 100 mA

If you would like more information on the possibility of using an infrared repeater with your Nº38, please contact your Mark Levinson dealer.
