using a turntable If a turntable is to be used with the Nº380, it must be used in conjunction
with a phono preamp such as the Mark Levinson Nº25. The phono preamp
used should provide RIAA equalization and deliver a line-level signal to the
input of the Nº380 (both standard functions of a phono preamplifier)..
7 EXTERNAL IR INPUT
The Nº380 incorporates an infrared repeater input to facilitate a wide range
of installation options. If desired, the Nº380 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 Nº380 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 milliamp s of current, with the tip of the 1⁄8" mini-plug
having positive polarity, as below:
