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.
DR500 (E-13)
Rev. C 10/94
Once the DMX music programming is received at your location, your DR500 Receiver and associated
audio components take over.
•
COMSTREAM DR200 Digital Audio Receiver

Choosing a Good Location
There are a few items to consider when selecting a location for your DR500 Receiver. Observe the
following Safety Precautions:
Safety Precautions
Carefully read and follow all safety, use, and operating instructions before
operating the DR500. Heed all warnings and cautions contained in this
User Guide. Retain these safety, use, and operating instructions for future
reference.
FOLLOW STARTUP PROCEDURE
Do not plug in the DR500 Receiver until you have connected the system and read Section 3: Basic
Operations.
PROVIDE A SAFE LOCATION
Place the DR500 on a stable surface of sufficient size and strength, where it will not be jarred, hit, or
pushed off its surface. Ensure that all cables and cords are out of the way and will not be tripped over, as
this could cause personal injury or serious damage to the DR500.
AVOID WATER AND MOISTURE
Do not expose the DR500 to any liquids, which are often found in flower vases, coffee cups, rain from
open windows, etc. If the DR500 is exposed to any liquid, contact your DMX affiliate, as serious damage
could occur to the DR500 or its components.
AVOID HEAT, HUMIDITY, AND DUST
To avoid internal damage, the DR500 should be placed away from all heat sources, including radiators,
heater ducts, etc., out of direct sunlight, and away from high humidity, excessive dust, or mechanical
vibrations, that can cause damage to internal parts.
PROVIDE ADEQUATE VENTILATION
To avoid overheating, place the DR500 on a smooth, hard surface that has 2" of clearance around the unit
and adequate air circulation. If the DR500 is placed in a closed area, such as a bookcase or rack, ensure
that proper ventilation is provided.
Never place the DR500 on a soft surface, such as a rug, sofa, or bed, that would obstruct the required air
flow into the DR500 ventilation slots.
USE CORRECT POWER SOURCE
Operate the wall mount power supply for the DR500 from a 120 V, 60 Hz outlet only. Take care not to
overload wall outlets or extension cords, as this increases the risk of fire or electrical shock.
ROUTE POWER CORDS SAFELY
Route power cords so they are not walked on or pinched. Pay particular attention to cords and connections
at the plugs, receptacles (such as power strips), and the point where they exit from the DR500 and attach to
other equipment. Do not place any items on or against power cords.
USE APPROVED ATTACHMENTS ONLY
Use only DMX-approved attachments with the DR500 Receiver..
DR500 (E-23)
Rev. C 10/94
Connecting the DR500 to Your Audio System
If your DR500 system has not been professionally installed, if you have disconnected your DR500
Receiver, or if you are adding a component, refer to the following steps and diagrams to help you connect
your system.
If you have questions or need assistance connecting any components to your DR500, please contact your
DMX MUSIC Affiliate Sales Support team.
To connect multiple DR500 Receivers to one antenna, refer to Appendix D.
Connection Guidelines
It is important that you follow these guidelines when making any DR500 system connection:
•
Do not plug the Receiver into an AC outlet until all connections have
been made and you have read the Startup procedures in Section 3:
Basic Operations.
•
Turn the audio system amplifier OFF and the volume completely
down.
•
•
Connections should be finger-tight only; never use pliers or a wrench.
The DR500 Receiver wall mount power supply is not polarized, and
any orientation on the wall or power strip is acceptable. When
mounting to a standard dual outlet, a screw is provided to prevent
accidental removal of the wall mount power supply.
•
The DR500 Receiver should not be plugged into an AC socket like
those found on the rear of audio amplifiers.
•
Once the DR500 is connected, turned on, and receiving the satellite
signal, it should remain plugged in to an unswitched (on) AC outlet so
that it can receive any programming updates, authorization commands,
and information from the DMX/DBS National Authorization Control
Center.
If the DR500 will not be used for extended periods of time, it should
be turned off using the front panel power switch only. It should not be
unplugged nor have its AC power turned off.

Antenna Installation and Alignment
It is recommended that the Satellite dish antenna be installed by your local DMX Affiliate. It is imperative
that the dish be securely and safely mounted, and pointed accurately at the Satellite. Brief instructions are
presented here for completeness.
Satellite Dish Installer: Ground the RF input cable to the building grounding system as close as possible
to the point of building entry. Refer to the National Electric Code (NEC) Article 820-40.
The following steps describe the process to properly set up, position, and connect the antenna using the
DR500 Receiver:
1. Determine the proper block converter and feed horn polarity adjustment for your
area.
2. Assemble the satellite dish antenna.
3. Locate the antenna in an area with an unobstructed line of sight to the satellite
coordinates (azimuth and elevation) for your area.
For information relating to satellite location and coordinates, antenna alignment, and
signal acquisition, contact your DMX affiliate.
4. Pre-position the antenna to the correct azimuth and elevation coordinates by using a
compass and inclinometer.
5. Pre-position the LNB to the indicated polarity setting.
6. Locate the DR500 Receiver within visual range of the antenna.
7. Connect a 75 ohm coaxial cable (RG-6, typical) from the output of the LNB to the
Receiver RF IN connector.
8. Connect 120 VAC power to the DR500 Receiver – do not turn it on.
Improvise a temporary sun shade over the DR500 front panel as the LED displays may be
difficult to read in direct sunlight.
9. Place the receiver in signal strength mode by depressing the power, channel up, and
channel down buttons simultaneously. Alternatively, this may be done with the
remote control using Preset 180.
−
The display reads nL, signifying it is not locked.
–
Channel 1 flashes on the front panel display indicating the receiver is muted
–
AUTH LED is Off unless the receiver is already authorized
–
SYNC LED is Off and remains so until the satellite is acquired
The signal strength level numbers are preceded by a minus sign (-) to differentiate them from
a music channel number. Signal Quality readings vary from -00 (the strongest level) to
approximately -80 (weakest level) before losing the satellite lock nL.
Rock the dish slowly from side to side and up/down around the nominal position. When the
Satellite has been located, the display will read out a negative number representing signal
strength and the Sync light will illuminate. Carefully move the dish to maximize signal, at
which time the readout will be the least negative (closest to zero). Tighten the bolts and
check that signal strength has not been disturbed by tightening the bolts.

Rev. C 10/94
Connecting Multiple Receivers to One Antenna
Multiple DR500 Receivers can be connected to one antenna. However, to avoid damage to either the antenna LNB and
DR500 Receiver, the following items must be used:
•
Correct splitter(s)
•
Proper line amplifiers
Line amplifiers may be required when using a signal splitter and/or when long coaxial cable runs
are required from antenna to receiver. All splitters and line amplifiers should be rated for satellite
IF processing with a minimum bandwidth of 950 MHz to 1450 MHz.
Since power is delivered to the LNB and line amplifier by the DR500 Receiver (18 VDC via RF IN connector), splitters
should have one DC power passing port. All other ports must block DC or have equivalent circuitry that only permits
one of the DR500 Receivers to power the LNB. Never connect via power passing splitters. Additionally, the receivers
not delivering power to the LNB should have their LNB power output switched OFF using Preset 160. Failure to do so
may result in severe damage to the antenna LNB and the DR500 Receivers
The line amplifier should be inserted just prior to the input of the splitter (not after the antenna LNB). For
best performance line amplifiers are typically inserted every 150 feet.
Recommended Equipment
The following equipment is recommended when multiple receivers are connected to one antenna:
•
•
High frequency splitters
−
QINTAR HFS-2 and HFS-4. Two and four port splitters that pass power from one
port.
−
QINTAR HFS-2WB and HFS-4WB. Two and four port 5 to 2050 MHz wide band
splitters with a built in zener diode circuit to protect DC return back to the DR500
Receiver. These splitters can be used in installations requiring power passing to only
one port.
In-line satellite amplifier
−
•
QINTAR LA-2050. This line amplifier has a bandwidth of 10 to 2050 MHz. It is
typically powered by the DR500 Receiver 18 VDC power.
Coaxial Cable
−
For short runs, under 150 feet, use a 75 ohm RG-59 coaxial cable.
−
For cable runs over 150 feet, use higher quality RG-6 or RG-11 cable to minimize
antenna signal loss and amplifier requirements.

Forced Tune Events
Forced Tune Events allow you to easily specify at what hour a particular channel will be played. Although
forced tune events sound simple, they’re actually a powerful function that provides you with a wide range
of musical programming flexibility and creativity, along with local manageability.
Setting Forced Tune Events
The DR500 allows you to program and store up to six forced tune events per day. These forced tune events
can be programmed for one channel or spread across a maximum of six channels.

Return Procedures 
DMX Affiliates
Follow these return procedures if you are a DMX affiliate who has purchased the DR500 receiver in question
and determined that the problem is specifically DR500-equipment related.
If it is necessary to return a product for repair, the following procedures must be followed:
1. Contact Affiliate Sales Equipment Support team at (206) 329-1401 and ask to speak with
Andrew McCullough or JJ Williams.
2. Should it be necessary to return a product to DMX for any reason, you will be issued a
return material authorization (RMA) number. To issue an RMA number, we will need the
product’s serial number and model number.
You will need to include a complete description of the problem, the operating conditions
which caused the problem, and any circumstances that may have led to the problem. This
information is essential for DMX repair technicians to reproduce, diagnose, and correct
the problem. In addition, include your contact person’s name and phone number in the
event a DMX representative needs to contact you.
4. Include a purchase order for any out-of-warranty repair work being performed. DMX will
begin repair work after a PO is received.
5. Reference the RMA number on all paperwork that accompanies the equipment, and write
the RMA number clearly on the outside of the shipping container.
6. Ship your module and power supply only (no accessories such as remote controls) in the
original shipping packaging or equivalent, prepaid, to the address provided by DMX
Customer Service.
All equipment upgrade and repair requests will be completely evaluated and the required
work performed in an expedient and prompt manner. The equipment will then be
thoroughly tested for compliance with appropriate specifications.

DR501 User Manual Addendum
We’ve added a powerful, new message marketing tool in the DR501 receiver that helps you
maximize the moment of contact with customers in your location. Message marketing educates
customers on product and service offerings to influence increased purchases, to provide quality
customer service, and to improve your business’ communications with customers.
The DR501 receiver delivers a complete music and marketing system for your business success.
The combined power of using music and message marketing reinforces company image,
enhances branding, and increases advertising exposure while entertaining customers.
Contact your local DMX MUSIC sales office to find out more about this capability.
Technical Installation Information
The DR501 has all the functionality of the DR500, with the new capability of message playback.
DMX MUSIC controls messaging functionality via our Satellite Operations Center.
To support the DR501’s message marketing functionality, one locally controlled preset command
has been added as described below.
Preset 450
This Preset toggles the analog music output level between 1VRMS and 2VRMS. The default
output level (as shipped from the factory) for the DR501 is 1VRMS max music level. Please note
that the DR500 had a max output level of 2VRMS. The DR501 default output level is lower than
the DR500; this is to allow for a higher volume output when messages play.
This reduction of the output level allows headroom for boosting the volume of messages over the
music level. The amount of boost is controlled by the Satellite Operations Center at DMX MUSIC.
If messages are to be played on the DR501, it is recommended that the default of 1VRMS
max level NOT be changed.
If it becomes necessary to change the default max output level of the DR501 using the remote
control may do it. Enter Preset 450; the display will indicate either “OL1” or “OL2”. The display
indicates what the receiver output level has been changed to. The volume change should be
audible, and get louder when changed to OL2 and softer when changed to OL1.
It is recommended that DR501s using message marketing have their front panels locked.
