The
RCA
input accepts
digital audio signal
(
DAS
) via cables equipped with
RCA-type connectors from digital sources such as a compact disc transport,
laser disc transport, digital audio tape transport, or digital broadcast receiver.
The RCA input conforms to the Sony/Philips Digital Interface Standard
(
S
/
PDIF
), which calls for a 75
Ω
transmission of the DAS. Use a digital inter-
connecting cable specifically designed for the 75
Ω
S
/
PDIF
standard, such as
Madrigal MDC-2 cable, when using this input.

BALANCED ANALOG OUTPUTS
These outputs normally provide balanced line-level analog audio (via cables
equipped with XLR-type connectors) to a preamplifier, integrated amplifier,
or receiver equipped with balanced inputs (see “Set-up and installation”).
The pin assignments used are AES-standard, as shown below:
1 2
3
Pin 1: Signal ground
Pin 2: Signal
+
(non-inverting)
Pin 3: Signal
–
(inverting)
Connector ground lug: chassis ground
Alternatively, you may elect to use the variable output capability of the Nº39
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 Nº39 in its factory-de-
fault setting of having a fixed (line level) output.

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.

as a volume control, driving the power amplifier in your system directly. Of

EXTERNAL IR INPUT
The Nº39 incorporates an infrared repeater input to facilitate a wide range
of installation options. If desired, the Nº39 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 Nº39 by any of a number of commercially-
available IR repeaters.
