Thank you for subscribing to Digital Music Express! This section describes the Direct Broadcast Satellite
(DBS) receiver and equipment that are used to deliver the best in CD-quality music. The equipment
includes:
• Satellite dish receiving antenna, low noise block (LNB) amplifier, and connecting cable
• Digital Audio Satellite Receiver, Model DR500
• Remote control device, Model DMR-22 or Model DMR-28 DMX/DJ
DR500 (E-11)

System Features
The DR500 DBS Satellite Receiver is a digital audio stereo decoder which easily integrates with most
stereo or monaural amplifier systems.
Key system features include:
• Full CD quality 20 kHz stereo
• 120 stereo pairs available on one transponder
• Dolby Digital compression
• Storecasting and datacasting capabilities
• User and network programmable forced tune events (dayparting)
• Exclusive DMX/DJ IR remote provides artist, album, and title information
• Multi-zone expansion capabilities
• Utilizes a small, one-meter satellite dish in most CONUS locations
• Digital audio output, Sony/Philips Digital Interface Format (SPDIF)
To fully appreciate the DMX/DBS service, you must have a separate stereo system that can be connected to
the DR500. (For information on connecting the system, refer to “Connecting the DR500 to the Audio
System” found in Section 2: Installation and Connections.
What is DMX MUSIC?
DMX MUSIC is an innovative music programming service that delivers up
to 120 channels of CD-quality, commercial-free music via satellite
transmission.
To provide you with this unparalleled digital sound service, DMX MUSIC
uses the latest satellite technology to deliver DMX/Direct Broadcast
Satellite (DBS) music to your location.
DR500 (E-12)
Rev. C 10/94
DBS System Overview
Although the use of satellites, satellite dishes, and receivers may seem complex, the DMX/DBS service
uses a highly sophisticated system that makes channel selection and local music programming easier and
simpler than using a VCR. It also allows DMX to deliver music of unprecedented linearity, sonic precision,
and exceptional fidelity.
The DMX/DBS premiere digital audio service uses the following satellite technology:
• Satellite Uplink Facility transmits music programming to the
satellite through satellite dishes
• Satellite relays the music programming signals to your satellite dish
antenna
• DBS Satellite Dish Antenna receives the music programming
transmitted from the satellite and relays it to the DR500 Receiver. Your
satellite dish can be as small as one meter and may be installed in
various places on or around your location. The only constraint is that
the satellite dish must be properly pointed at the satellite with no
obstacles blocking the satellite signal.

Once the DMX music programming is received at your location, your DR500 Receiver and associated
audio components take over.
• DR500 Digital Audio Satellite Receiver receives and decodes the
digital audio programming information and sends it to your stereo
amplifier system
Additional DR500 receivers provide you with additional
flexibility to create tailored music programs for multiple business
environments that you can vary by the hour. Additional units can
be integrated into your system at any time.
• Remote Control device allows you to control and program the
DR500 Receiver and DBS system
There are two available remote control devices: the DMR-22, which is
a basic remote control device, and the DMR-28 DMX/DJ, which
provides additional programming information and functionality.

DR500 System Components
The DR500 Digital Audio Satellite Receiver is a digital audio stereo decoder that easily integrates with
most stereo or monaural amplifier systems.
DR500 Digital Audio Satellite Receiver
The DR500 is the master receiver that connects to the satellite dish and your stereo or monaural amplifier
system.
DR500 Front Panel
The front panel of the DR500 is used to turn the DR500 on and off and manually select music channels.
The front panel consists of:
• Power selector turns the DR500 on and off
When the DR500 is Off, a small green light appears on the front panel, indicating
that the DR500 is able to receive any information from the DMX/DBS National
Authorization Control Center.
• Music channel selectors allow you to tune to the next higher Ù or lower Ú channel
If remote channel selection is preferred, use either the DMR-22 or DMR-28 DMX/DJ
Remote Controls.
• Front panel display shows the current channel selection as well as other DR500
information
• Stereo/Mono A/Mono B indicators - illuminates green to indicate either a stereo channel,
or one of two mono subchannels.
• Sync indicator illuminates green when the DR500 Receiver has locked onto the
satellite
• Authorized indicator illuminates green when you are authorized to receive the current
channel
• LNB PWR illuminates green to indicate LNB power is enabled. No illumination
indicates LNB power is disabled. Blinking indicates a problem with the LNB power
supply. (For more information, refer to Section 5: Maintenance and Troubleshooting.)
