Output Connections
The RCD-1520 gives you a choice of two different kinds of outputs –
an analog output signal from the built-in D/A converter for use with
conventional analog audio components and a coax digital output
which provides an unprocessed digital signal for use with outboard
D/A converters or digital processors.
Note: To prevent loud noises that could damage your speakers, turn
off all the system components when you make any signal connections.
Analog Outputs
y
[See Figure 3 for wiring illustration]
A pair of standard RCA jacks supplies an analog output signal from
the RCD-1520 to the source inputs of an audio preamplifier, integrated
amplifier, or receiver.
Select high quality audio interconnect cables. Connect the left and
right channel outputs of the RCD-1520 to the corresponding inputs on
the preamplifier or other component.
Digital Output
u
[See Figure 4 for wiring illustration]
If you are using an outboard D/A converter or other digital processor,
you will need an unprocessed digital data stream from the RCD-1520.
Using a standard 75 ohm coax digital cable, connect the RCD-1520's
digital output to the digital input connector on the outboard D/A
converter.
When playing CD-DA, MP3 and WMA discs the Digital Output
provides a PCM data stream. When a dts-CD is played a dts data
stream is provided.
Note: When an HDCD disc is played "HDCD" appears in the
display. However the analog output is not HDCD decoded.
12 Volt Trigger Input
p
The RCD-1520 can be activated by a 12 volt trigger signal. The
trigger input accepts any control signal (AC or DC) ranging from 3
volts to 30 volts. When a cable is connected to the 12V input and a
trigger signal is present, the RCD-1520 is activated. When the trigger
signal is turned off, the unit goes into standby mode. The front panel
power indicator remains lit, but the display goes dark and the unit will
not operate.
NOTE: When using the 12V Trigger feature, leave the POWER button
in the ON position.
EXT REMOTE IN Jack
o
This 3.5mm mini-jack receives command codes from industry-standard
infrared receivers via hard-wired connections. This feature could prove
useful when the unit is installed in a cabinet and the front-panel sensor
is blocked. Consult your authorized Rotel dealer for information on
these external repeaters and the proper wiring of a jack to fit the mini-
jack receptacle.

Computer I/O Connector
The RCD-1520 can be operated from a personal computer running
audio system control software from third-party developers. This control
is accomplished by sending the operating codes normally sent by the
RR-D97 remote control over a hard-wired network connection from the
computer.
The COMPUTER I/O input provides the necessary connection on the
back panel. It accepts standard RJ-45 8-pin modular plugs, such as
those commonly used in 10-BaseT UTP Ethernet cabling.
For additional information on the connections, software, and operating
codes for computer control of the RCD-1520, contact your authorized
Rotel dealer.
Operation
The RCD-1520 can be operated using its front panel buttons or from
corresponding buttons on the supplied infrared remote control. Specific
instructions for each of these controls are detailed below. Most of
the buttons are duplicated on the front panel and on the IR remote
control. However, there are a few exceptions where the buttons are
only available on one or the other. These exceptions are noted in the
instructions.
Infrared Remote Control
8
Before using the IR remote control, it is necessary to install two "UM-4/
AAA" batteries (supplied). Remove the plastic cover on the back of
the IR remote, install the batteries (observing the + and – polarity
indications), and reinstall the cover.
To use the IR remote control, aim it at the IR sensor
lower left corner of the RCD-1520 front panel.
Display
5
A lighted Display on the front panel of the RCD-1520 provides useful
information about the status of the unit, activation of special features,
and track/time information for the disc being played. Each of these
indicators is described in the detailed operating instructions that
follow.
Disc Slot
=
A disc slot located in the center of the RCD-1520, accepts the disc and
pulls it into the disc transport. Insert the disc label-side up. After the
disc is loaded the display shows the number of tracks on the disc.
