"Linked amplifiers?" you ask
The communication required between preamplifier and power amplifier(s) is
more limited than between other components. In particular, the new 300 series
Mark Levinson amplifiers will:
• toggle between standby and operate in conjunction with the
Nº38(S) they are Linked to;
• when in standby, all of the standby indicator LEDs (sources,
preamp and power amps) blink in sync with one another;
• report certain fault conditions to the preamplifier if they must shut
down for some reason.
For this reason, it made sense to define a somewhat simpler communications
Link between preamps and power amps. In this case, the Nº38 or Nº38S acts as
the "master" to the power amplifier(s) "slave." Multiple amps may be daisy-
chained via their
slave in
work" and passes necessary information back and forth as needed.
Hence, our seemingly confusing nomenclature on the rear panels of the various
products. "Master" is connected to "Slave In" , then the daisy-chain continues to
Slave Out, to Slave In, to Slave Out, etc., until you reach the preamplifier's Slave
input. From there, you connect the Nº38's Master to the power amp's Slave In. If
you have more than one amp in the system, daisy chain them Slave Out to Slave
In (up to a maximum of six amplifiers). (See sample diagram below.)
