SECTION 1
GENERAL INFORMATION
1.1 INTRODUCTION
The purpose of this manual is to describe the proper installation and operation of the Wegener
Communications®Diamond DX™Messaging Unit.
1.2 UNIT DESCRIPTION
The Wegener Diamond DX unit is a satellite-delivered messaging system whose function is to
store advertising material, or ‘spots,’ during nonuse hours, schedule them, and play them back
during the normal music program. Most of these functions are performed by the network uplink,
but some local recording and playback may be accomplished, if desired.
1.2.1 System Function
Refer to Figure 2-1. A satellite downlink carrier is received by a Wegener Satellite Audio
Receiver (e.g. Wegener 1916 Receiver). The receiver’s output is an audio channel and a control
stream. Within this control stream are embedded instructions to the Diamond DX™to record
advertisement spots and then schedule them for playback. In addition, it supplies updates for the
on-board real-time clock.
Most of the time, the unit passes the audio input straight through to its output. However, during
non-business hours, the audio may contain several advertisement spots. These are stored to a
PCMCIA memory card. Later, per its schedule during business hours, these advertisements are
inserted into the audio output. In addition, local advertisements or announcements may be
recorded using a microphone input and, under network control, scheduled to play back at specific
times. These may also be played back under local control.
1.3 YEAR 2000 COMPLIANCE STATEMENT
Muzak recognizes concerns for the effect of date interpretation beyond year 1999. The two-digit
year date format commonly used in the world’s computer systems was avoided in favor of the
four-digit format for Muzak’s Satellite Addressable Control System. All Muzak satellite
receivers include no date logic and therefore will not be affected. The Diamond DX messaging
unit does in fact operate within date limits, but has been designed to follow the four-digit
standard. Therefore, they also will be unaffected by the date interpretation issues.
1.4 GLOSSARY OF TERMS
The following terms are used throughout this manual.
!Ad ID: The network database identification number for a specific spot (e.g. 30-
second Chevy-Blazer-running-rough-terrain ad).

PWR100-002 1-2
!Event: A single scheduled command (e.g. to begin playing a spot).
!Fade: The gradual lowering of volume as one audio (ex. Music) “fades out,” and the
gradual raising of volume as another audio (ex. Spot) “fades in.”
!Group: Indirect addressing method where a unit may be addressed along with other units
who share a similar characteristic, such as geographic location, network status, etc.
!Local Spot:An ad recorded from unit’s MIC input by the local user.
!Messaging unit or “unit”: The Diamond DX unit.
!PC Card: PCMCIA FLASH Memory storage card.
!Audio Processing Card: Internal audio storage/playback card.
!Schedule: A sequence of commands which is stored in memory and then executed at a
specific time. This is used to “schedule” ads (spots) for play at specific times.
!Spot:Individual audio segment or advertisement
![xxx]:Front Panel Display outputs are shown as text enclosed by brackets.
1.5 MAJOR FEATURES
The major features of the Diamond DX unit are listed below:
1.5.1 Features List
!Main audio output may be programmed to pass-thru the audio input, or play back a
prerecorded spot.
!Spots may be recorded, under network control, from the audio input.
!Spots are digitally recorded, with selectable sample rates and compression modes, for
optimizing quality vs. storage-space tradeoffs.
!Spots are stored on removable PCMCIA memory cards.
!Real time clock is maintained by network.
!Network controls nearly all functions for ease of local operation.
!Volume control of spot playback and music.
!Unit is powered by external +12VDC wall-mount power supply.
!Microphone input for storing locally-created spots.
