4RECORD OUTPUTS
Connect these outputs to the right-channel and left-channel tape inputs of your recorder. Make a note of which set of record outputs you used with which recording device. It is important to name the inputs you use and to associate the correct record output with the appropriate recording device.
By giving the Nº380 this information, it can prevent accidental record loops that might otherwise create disturbing feedback. (See “programming input names” and “assigning record outputs” on pages 20-21.)
These outputs are unaffected by the output level control on the front panel of the Nº380, or by the source chosen to be monitored.
5SLAVE AND MASTER COMMUNICATOR PORTS
These communications ports allow the Nº380 to “link” to certain compat- ible Mark Levinson components. (See “Linked Functions.”)
The Mark Levinson Linking system uses a Digital Audio Processor as the Master of (and central clearinghouse for) inter-component communications. Other components 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 ultimate destination of all source signals, the Nº380 Preamplifier must be the final “Slave” in the chain. (In technical terms, it terminates the communications bus.) In turn, the Nº380 can serve as a master to an asso- ciated compatible Mark Levinson power amplifier—hence its “Master” com- munications port.
Thus, if the only other Mark Levinson Link-compatible component you have is a digital audio processor, connect its master port to the Nº380’s slave port using a “straight-through” RJ-45 cable. If there are additional Mark Levinson Link-compatible components in the system, place the Nº380 at the end of the chain by connecting the last slave out port to the Nº380’s slave port. See the diagram (left) for clarification.
The RJ-45 cable needed for the Link connection between source compo- nents 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 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.

The power amplifier Link connection is made using a 6-conductor Link cable. Connect the Nº380’s master port to the slave port of a compatible Mark Levinson power amplifier.
