5. single-ended analog outputs

These outputs provide single-ended line-level analog audio

(via cables equipped with RCA-type connectors) to a preamplifier,

integrated amplifier, or receiver.

Alternatively, you may elect to use the variable output capability

of the Nº390S as a volume control, driving the power amplifier

in your system directly. Of course, this approach is only

appropriate in relatively simple systems lacking any analog

sources.

Since many people have at least one analog source, they will

be better off having a full preamplifier to coordinate the

operation of the entire system—digital and analog. In this

case, you would leave the Nº390S in its factory-default setting

of having a fixed (line level) output.

6. external IR input

The Nº390S incorporates an infrared repeater input to facilitate

a wide range of installation options. If desired, the Nº390S

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 Nº390S by any of a number of commercially-

available IR repeaters.

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

below:

If you would like more information on the possibility of using an

infrared repeater with your Nº390S, please contact your Mark

Levinson dealer.
