DIGITAL DC IN
This input accepts DC power from the PLS-330 (via the supplied cable
equipped with two-pin connectors).
Connect
dc in (digital)
on the rear panel of the Nº30.5 to the
dc out (digi-
tal)
on the rear panel of the PLS-330.

AES/EBU ELECTRICAL DIGITAL INPUTS (1 – 3)
These inputs accept the
digital audio signal
(
DAS
, via cables equipped with
XLR-type connectors) from digital sources such as a compact disc transport,
laser disc transport, digital audio tape transport, digital broadcast receiver.
These inputs conform to the AES/EBU digital interconnection standard,
which calls for a 110
Ω
transmission of the DAS. Use a digital interconnecting
cable specifically designed for the 110
Ω
AES/EBU standard, such as Madrigal
MDC-1 cable, when using these inputs. The pin assignments for the AES/
EBU digital interconnection standard are shown below.
Pin 1: chassis ground
Pin 2: Signal
+
(non-inverting)
Pin 3: Signal
–
(inverting)
Connector ground lug: chassis ground
Caution!
When using a digital recorder (like a DAT) that also allows
recording of analog signals, a specific combination of
interconnections and settings on the digital recorder, the
Nº30.5, and an associated preamplifier may create a
“feedback loop” that may damage your system’s
loudspeakers. For guidance in avoiding such a feedback
loop, consult your Mark Levinson dealer.

S/PDIF RCA ELECTRICAL DIGITAL INPUTS (4 – 5)
These inputs accept the
digital audio signal
(
DAS
, via cables equipped with
XLR-type connectors) from digital sources such as a compact disc transport,
laser disc transport, digital audio tape transport, digital broadcast receiver.
These inputs conform to the Sony/Philips Digital Interface Standard (S/
PDIF), which calls for a 75
Ω
transmission of the DAS. Use a digital intercon-
necting cable specifically designed for the 75
Ω
S/PDIF standard, such as
Madrigal MDC-2 cable, when using these inputs.
