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:
