Thank you for subscribing to Digital Music E press! 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-12)

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)
• E clusive DMX/DJ IR remote provides artist, album, and title information
• Multi-zone e pansion 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 ection 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-13)
Rev. C 10/94
DBS System Overview
Although the use of satellites, satellite dishes, and receivers may seem comple , 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 e ceptional 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.

DR500 (E-14)
Rev. C 10/94
Once the DMX music programming is received at your location, your DR500 Receiver and associated
audio components take over.
COMSTREAM DR200DigitalAudio Receiver DIGITALAUDIO
• 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
fle ibility 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 anel
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 ne t 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 ection 5: Maintenance and Troubleshooting.)

DR500 (E-16)
Rev. C 10/94
DR500 Back anel
The back panel of the DR500 has a variety of connectors that are used to link the satellite dish to the
DR500 and your audio system to the DR500.
The back panel consists of:
• Power Input  attaches the DR500 to a 120 VAC wall mount supply
• RF IN connector  attaches the DR500 Receiver to your local satellite dish
• Mono Out connector  attaches the DR500 to a monaural receiver or amplifier
• Stereo Out connectors  attaches the DR500 to a stereo receiver or amplifier. Left is coded
white; right is coded red.
• Digital Out connector (standard Sony/Philips Digital Interface Format [SPDIF] coa ial output;
coded black)  attaches the DR500 to a digital input of audio equipment that has a coa ial digital
input.
• Data/Control connector  for PC control and diagnostics
• Serial ID number/bar code label — lists the serial number for this unit

DR500 (E-17)

DMR Remote Control Units
To select music channels remotely, you can use either the DMR-22 or DMR-28 DMX/DJ remote control
units. Both remote control models have the following features:
• Individual channel selection keys that allow you to move through the authorized channels one
channel at a time either up or down
• Preset channel selection key that allows you to enter special music programming information
• Scan key that allows you to step through each authorized channel, each playing for five
seconds
• Mute function that allows you to turn the audio on and off
• Last channel recall function that allows you to return to the previously selected channel
To use either remote control unit, point it toward your DR500 Receiver and press the appropriate keys. The
remote control units can be used at distances of up to 10 meters (32 feet) while you are directly in front of
and in a straight line to the DR500 Receiver.
Communication between the remote control and DR500 will be impaired if there are obstructions blocking
the transmission or if the remote control is not directed straight at the DR500. If the remote control fails to
operate, refer to ection 5: Maintenance and Troubleshooting.

Additional DR500 Receivers
Additional DR500 receivers can be added to your system at any time. Each receiver allows you to select
and play one different DMX music channel on a separate audio system. This provides additional stereo
music channels to cover other locations or zones.
Two or more DR500 Receivers may be connected to one antenna to provide
different music channels via separate audio systems. For additional information
regarding the connection of multiple receivers to one antenna, refer to Section 2.
