INTRODUCTION

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 amplifi er 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 fi le 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 fi le by 10 times.

1.3 Encoder

1.4 Decoder

Software which decompresses an MP3 audio fi le 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 fi les. 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 fi le 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
fi le of about 5 minutes (.wav) and compressed in MP3 at 128Kbps (MP3).

WAVE 51.1MB

MP3 4.6MB

Software which compresses a CD audio or wave fi le 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:

DESCRIPTION AND CONNECTIONS

3.3 Power supply

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.

3.4 Logic inputs

The DMA1 has eight multi-function logic inputs to control the playing of the
either playlists or individual audio fi les.

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 fi le, 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)

3.6 Serial RS485 connection

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).

3.7 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 Amplifi ed audio output

Amplifi ed 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 amplifi ed audio output
terminals can be a potential source of interference.

PAGE 8 AMIS-DMA1 INSTALLATION & OPERATION MANUAL

CONFIGURATION FILE

4.1 What is the confi guration fi le?

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 confi guration fi le stored in the main directory of the fl ash memory,
together with the audio fi les, makes it possible to programme the various
parameters of the DMA1.

This fi le must be assigned the name confi g.txt (this extension has been used
so it can be modifi ed by any text editor, including PocketPC text editors).

4.2 Content of the confi guration fi le

Each line of the confi guration fi le 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 fl ash memory card is in­serted, the DMA1 will start to read the main directory of the fl ash memory.
If the fi le confi g.txt is found, the DMA1 will store the confi guration 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 fl ash memory card removed. It is therefore not manda­tory for the confi guration fi le to always be present on the fl ash memory
card. Once all the parameters have been read and stored to the DMA1, the
confi g.txt fi le can be deleted.

NOTE: If it is necessary to confi gure multiple DMA1s with the same
confi guration parameters, a single fl ash memory card with the
appropriate confi g.txt fi le can be prepared and sequentially insert
this memory card into all the DMA1s to be confi gured. The fi nal
fl ash memory cards to be inserted into each DMA1 now only need
to contain the MP3 audio fi les.

4.4 Preparing the fi le

Any ordinary text editor (like Windows Notebook) can be used to create the
confi g.txt fi le. The fi le must be saved as a pure text fi le (.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 fi le.

4.5 Storing fi les in fl ash memory

The confi guration fi le and all the MP3 audio fi les can be stored to the fl ash
memory card via a special USB reader/writer for PC.

PAGE 9AMIS-DMA1 INSTALLATION & OPERATION MANUAL
