IMPORTANT SAFETY INFORMATION
1.Save the carton and packing material even if the equipment has arrived in good condition. Should you ever need to ship the unit, use only the original factory packing.
2.Read all documentation before operating your equipment. Retain all documentation for future reference.
3.Follow all instructions printed on unit chassis for proper operation.
4.Do not spill water or other liquids into or on the unit, or operate the unit while standing in liquid.
5.Make sure power outlets conform to the power requirements listed on the back of the unit.
6.Do not use the unit if the electrical power cord is frayed or broken. The power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords and plugs, convenience receptacles, and the point where they exit from the appliance.
7.Always operate the unit with the AC ground wire connected to the electrical system ground. Precautions should be taken so that the means of grounding of a piece of equipment is not defeated.
8.Mains voltage must be correct and the same as that printed on the rear of the unit. Damage caused by connection to improper AC voltage is not covered by any warranty.
9.Have gain controls on amplifiers turned down during power-up
to prevent speaker damage if there are high signal levels at the inputs.
10Power down & disconnect units from mains voltage before making connections.
11.Never hold a power switch in the “ON” position if it won’t stay there itself!
12.Do not use the unit near stoves, heat registers, radiators, or other heat producing devices.
13.Do not block fan intake or exhaust ports. Do not operate equipment on a surface or in an environment which may impede the normal flow of air around the unit, such as a bed, rug, weathersheet, carpet,
or completely enclosed rack. If the unit is used in an extremely dusty or smoky environment, the unit should be periodically “blown free” of foreign matter.
14.Do not remove the cover. Removing the cover will expose you to potentially dangerous voltages. There are no user serviceable parts inside.
15.Do not drive the inputs with a signal level greater than that required to drive equipment to full output.
16.Do not connect the inputs / outputs of amplifiers or consoles to any other voltage source, such as a battery, mains source, or power supply, regardless of whether the amplifier or console is turned on or off.
17.Do not run the output of any amplifier channel back into another channel’s input. Do not parallelor series-connect an amplifier output with any other amplifier output. Australian Monitor Inc is not responsible for damage to loudspeakers for any reason.
18.Do not ground any red (“hot”) terminal. Never connect a “hot” (red) output to ground or to another “hot” (red) output!
19.Non-use periods. The power cord of equipment should be unplugged from the outlet when left unused for a long period of time.
20.Service Information Equipment should be serviced by qualified service personnel when:
A.The power supply cord or the plug has been damaged.

1.1 Introduction
The Australian Monitor Installation Series DMA-1 digital message announcer is a compact yet highly featured digital playback device. Utilizing an SD card digital storage format the DMA1 delivers high quality stereo audio in an MP3 format. Messages can be played or triggered using the on-board controls, via remote switches, contact closure or via RS485 serial control. The DMA-1 also boasts an on board 20 watt per channel D class power amplifier as well as stereo inputs & outputs which allow it to be inserted in line with another BGM feed.
The DMA-1’s compact size belies the wealth of features it offers. It is a highly innovative & cost effective digital message storage & playback device that has a host of commercial applications.
1.2 What is MP3?
MP3 is an acronym for Mpeg-1 layer 3. This is an audio compression standard which eliminates sounds which the human ear cannot hear via a psycho-acoustic algorithm. The purpose of this compression is to reduce the space taken up by an audio file while still ensuring excellent quality. The greater the compression, the less the audio quality. The right compromise, which guarantees a quality comparable to that of a Compact Disc, is 128 Kbps (thousands of bits per second) which represents the most widely used manner, and reduces the size of an uncompressed file by 10 times.
1.3 Encoder
Software which compresses a CD audio or wave file in MP3. There are many programmes of this kind, and it is virtually impossible to say which is the best. Freeware software encoders suitable for various
operating systems can be downloaded from the following internet site: www.mp3server.4t.com
1.4 Decoder
Software which decompresses an MP3 audio file in order to send it to a digital-analog converter and reconstruct the original audio signal.
1.5 Player
Hardware and software system able to read MP3 audio files. The DMA1 is able to carry out this function.
1.6 Wave
High quality audio format (extension .wav), compatible with the tracks of normal music CD’s. CD quality music utilises a sample rate of 44.1 KHz/sec. at 16 bit in stereo, but the size of the file is approximately about 10Mb per minute.
1.7 Audio compression in various formats
The following graphic shows the space taken up by an uncompressed audio file of about 5 minutes (.wav) and compressed in MP3 at 128Kbps (MP3).

3.3 Power supply |
3.6 Serial RS485 connection |
The DMA1 may operate with the following main power adaptors: 1215VAC, 12-24VDC.
It is recommended to use the mains adaptor supplied with the device. The red POWER LED lights up when power is present.
The DMA1 can be connected to an RS485 bus that can be controlled by a Crestron control system, or any other RS485 enabled control system. To enable RS485 control, (pin IN5/485A and IN6/485B), remove the cover of the DMA1 and move the relative jumpers (see para. 9.1).
3.4 Logic inputs
The DMA1 has eight multi-function logic inputs to control the playing of the either playlists or individual audio files.
The pins are:
1- |
GND |
2- |
IN 1 |
3- |
IN |
4- |
IN 3 |
5- |
IN 4 |
6- |
IN 5 |
7- |
IN 6 |
8- |
IN 7 |
9- |
IN 8 |
In order to activate the playing of a file, connect the desired logic input pin to GND (or the desired logic input pins when operating in binary logic).
3.5 IN/OUT 8 - input/output Vlink
Programmable logic input/output to connect two DMA1s in cascade, for synchronised management of music playlists with commercials/spots at scheduled intervals without interruptions.
Vlink: 0 = in standby
1 = in play (+12V)
3.7 Line level audio input
Line level audio input (stereo) allowing the connection of an external music source (SAT, CD, Tuner, second DMA1 etc) that is mixed with DMA1 generated audio. This functionality allows the mixing of a music source with scheduled commercials or spot announcements.
3.8 Line level audio output
Line level audio output (stereo) on extractable terminal strip.
3.9 Amplified audio output
Amplified stereo audio output (20W + 20W) for the connection of external speakers.
Connect external 4/8Ω speakers to the SPK L/GND and SPK R/GND terminal strip.
It is recommended to cable the DMA1 far from power cables. The two cables that connect the speaker with the DMA1 amplified audio output terminals can be a potential source of interference.

4.1 What is the configuration file?
The DMA1 is a very versatile device which can be adapted to the needs of the application in which it is used. Different applications may require
adjustment of volume, tone, loudness, communication parameters and timing. The configuration file stored in the main directory of the flash memory, together with the audio files, makes it possible to programme the various parameters of the DMA1.
This file must be assigned the name config.txt (this extension has been used so it can be modified by any text editor, including PocketPC text editors).
4.2 Content of the configuration file
Each line of the configuration file consists of:
•Mnemonic code of the parameter to be set. It always consists of our CAPITAL alphanumeric characters, and must always be at the beginning of the line. No more than one parameter is permitted on the same line
•Separating ‘=’ character. This MUST be inserted just after the mnemonic code, without any spacing or tab characters
•The relevant numerical parameter expressed as a decimal, to be inserted directly after the separation character, without any spacing or tab characters
Example: LMP3=14
LOUT=14
LLIN=14
LLI2=5
LLOU=10
LTRE=10
LBAS=10
MOMD=0
4.3 How it is managed by the DMA1
At the time the DMA1 is turned on, or when the flash memory card is inserted, the DMA1 will start to read the main directory of the flash memory. If the file config.txt is found, the DMA1 will store the configuration parameters into its own internal non-volatile memory. The parameters therefore stay in the internal memory of the DMA1 even after the device has been turned off or the flash memory card removed. It is therefore not mandatory for the configuration file to always be present on the flash memory card. Once all the parameters have been read and stored to the DMA1, the config.txt file can be deleted.
NOTE: If it is necessary to configure multiple DMA1s with the same configuration parameters, a single flash memory card with the appropriate config.txt file can be prepared and sequentially insert this memory card into all the DMA1s to be configured. The final flash memory cards to be inserted into each DMA1 now only need to contain the MP3 audio files.
4.4 Preparing the file
Any ordinary text editor (like Windows Notebook) can be used to create the config.txt file. The file must be saved as a pure text file (.txt). Should other programmes be used (e.g. Microsoft Word) be careful to save the document as “text only”: otherwise control characters would be inserted which would make it impossible for the DMA1 to interpret the file.
4.5 Storing files in flash memory
The configuration file and all the MP3 audio files can be stored to the flash memory card via a special USB reader/writer for PC.

4.6 Audio adjustment parameters
The DMA1 allows for the following audio adjustments:
•Independent adjustments of the MP3 file level, line level audio input volume and general amplified/line level output volume
•Adjustment of loudness level
•Separate adjustment of bass and treble tone control
•Adjusting the level of the background music while delivering commercials/spot announcements
•Activation/deactivation of power amplifier muting mode
The following tables show the relation between the value set in the configuration file and the actual value of the audio parameter.

4.9 Input management parameters
The playing of MP3 files takes place by activating the logic inputs. The
activation modes are set through the IMOD, TPCM MICP and MIRS param-
eters inserted in the configuration file.
Example: IMOD=0
TPCM=10
MICP=1
MIRS=0

DESCRIPTION OF TIMING PARAMETER |
|
|
IMOD |
Setting the mode of the logic inputs as either active high or active low |
|
|
TPCM |
Setting the persistence time of the input command (time to wait before the DMA1 |
|
interprets the input command) expressed in decimals of milliseconds (value between |
|
0 and 255 in decimal). |
|
|
MICP |
Setting Mode Input Continuous Play |
|
|
MIRS |
Setting Mode Input ReStart |
|
|
|

IMOD (INPUT MANAGEMENT MODE) |
|
|
|
IMOD |
0 = active-low input mode; the logic input is active when connected to the ground/GND of the device |
|
|
|
1 = active-high input mode; the logic input is active when connected to a positive voltage |
|
between 5 and 12VDC |
|
|
TPCM (TIME PERSISTENCE INPUT COMMAND MODE)
TPCM |
0 |

|
|
|
|
MICP |
0 |
= having terminated the playing of the MP3 file, the DMA1 goes into standby |
|
|
|
|
|
|
1 |
= the requested MP3 file is continuously played until a new input code is entered |
|
|
|
|
|
|
|
|
|
MIRS (MODE INPUT RESTART) |
|
|
|
|
|
||
MIRS |
0=repeated activation or deactivating of the same input code does not influence the |
||
|
playing of the relevant MP3 file. Only the activation of a different code can stop the playing |
||
|
of the current MP3 file and activate the playing of a new MP3 file |
||
|
|
