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 i

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 8 located in the 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.
