RJ-45 cables and connectors are used throughout the world for both tele-
communications and computers, and are widely available. The connectors
are crimped on to the ends of the cable such that pin 1 at one end is con-
nected to pin 1 at the other end. Such a “straight-through” connection is
(counter-intuitively) made by introducing a 180
°
twist in the cable between
the two ends, as shown below.

Connecting the communication ports other than as
described in this manual will damage the Nº38 and the
associated Mark Levinson components, and will void those
products’ warranties.

DIGITAL DC IN
This input accepts DC power from the PLS-330 (via the supplied cable
equipped with two-pin connectors).
Connect
digital dc in
on the rear panel of the Nº30.6 to the
digital dc out
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.
