Testing Procedures
The following testing procedures should be applied for every installation:
♦ All speaker zones shall be tested for impedance with a Goldline ZM-1 or like model.
Note that all Volume Controls need to be set “wide open”. Insure that signal
frequency sent is within Speaker Tolerances, i.e.…..1K Hz to Subwoofer will not
work, should be 100 Hz. Impedance will be noted on IR.
♦ Line levels in rack shall be tested for proper phase using a Goldline Phase Checker or
like model.
♦ All Speakers in System shall be tested for phase using a Goldline Phase Checker or
like model.
All DMX Installations that have “Commissioning” included in the Equipment List,
Subcontract Agreement, or Scope of Work, will require that the following be performed
in addition to the above steps.
Balance gain structure to +4 dBu as per DMX FASST Requirements.
1. This level should be achieved after the source player.
2. Level should be consistent throughout entire system, up to the amplifier output.
Note: This measurement should be performed with a good quality voltmeter. The meter should be
rated for “True RMS”.
♦ EQ the system, as per DMX FASST Requirements
1. Insert Goldline Pink Noise Generator, or like model, into signal path.
2. Set Amplifier Output to reflect 94 dB in room being measured. Note: all VC’s
should be wide open.
3. Measure room with Goldline Real Time Analyzer. Make adjustment to EQ
Faders so that all frequencies are relatively flat. Note: Readings should be + or
– 3 dB, they don’t have to be perfectly flat!
4. Remove Pink Noise Generator. Reinstall source/s and play customer’s content
over system, i.e. Profusion X, DBS Receiver, etc.
5. Listen for “Bad Sound”, too much bass, very bright, etc.
6. Make “Fine Adjustments” by ear.
7. Ask for customer input as to the sound of the room.
8. Repeat steps 1&2. Take final measurement of room and save settings on RTA.
9. Replace source and complete commissioning note section of IR.

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.
Page 45
Once the DMX music programming is received at your location, your DR500 or DR200
Receiver and associated audio components take over.
COMSTREAM DR200 Digital Audio Receiver
Digital Audio Satellite Receiver ⎯ receives and decodes the
digital audio programming information and sends it to your
stereo amplifier system
Additional 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 types: the Standard
remote, which is a basic remote control device, and the DJ, or
ICX remote which provides additional programming information
and functionality.
Page 46
Remote Control Units
To select music channels remotely, you can use any DMX remote control unit. All
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 or 200 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 Receiver.
Communication between the remote control and receiver will be impaired if there are
obstructions blocking the transmission or if the remote control is not directed straight at
the receiver. If the remote control fails to operate, refer to the manual for the respective
receiver for troubleshooting tips.

Antenna Installation and Alignment
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.
4. For information relating to satellite location and coordinates, antenna
alignment, and signal acquisition, contacts your nearest DMX office.
5. Pre-position the antenna to the correct azimuth and elevation coordinates by
using a compass and inclinometer.
6. Pre-position the LNB to the indicated polarity setting.
7. Locate the DR500 Receiver within visual range of the antenna.
8. Connect a 75 ohm coaxial cable (RG-6, typical) from the output of the LNB to
the Receiver RF IN connector.
9. Connect 120 VAC power to the DR500 Receiver – do not turn it on.
10. 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.
11. Channel 1 flashes on the front panel display indicating the receiver is muted
12. AUTH LED is Off unless the receiver is already authorized
13. SYNC LED is Off and remains so until the satellite is acquired
14. 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.
15. 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.
Page 48
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, or be diode
steered. 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, unless using diode steered splitters. 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
Channel Master 2212IFD. Two port splitter, diode steered. Not necessary to
disable LNB power from 2nd receiver.
Channel Master 2414IFD. Four port splitter, diode steered. Not necessary to
disable LNB power from any receiver.
In-line satellite amplifier. Channel Master 5113IFD line amp.
Coaxial Cable. Maybe necessary to use RG-11 for longer runs, over 300’.
DMX reserves the right to inspect all DMX jobs in progress or completed.
DMX’s field inspections are intended to assure that all work performed meets the
standards set forth in this manual and a project’s scope of work. If the field
inspection determines that the work performed is not within DMX’s standards,
DMX will provide the Sub-Contractor a detailed punch list in order to correct the
disparity. If the Sub-Contractor cannot correct the discrepancies within 48 hours
or the given customer deadline, they may incur the cost in correcting or
completing the job.
