DESCRIPTION
BMS1 is a High Quality Digital Message Player, designed specifically for
Background Music applications.
It can play Music Only or a mixture of Music and Messages, where
Messages can be automatically played at a User Selectable frequency.
The heart of BMS1 is a professional quality MP3 engine, which is controlled
by a powerful microprocessor in order to provide exceptional message output
quality.
It incorporates a powerful amplifier, with a Mono 100V output, designed to
drive up to Eight 100V speakers, operating at background audio levels.
BMS1 also has a Stereo Line Level output , for those sites which require an
amplifier to drive more than Eight 100V Speakers.
BMS1 is designed to only play MP3 files that have been Encrypted with
a BMS file Encryption program.

OPERATION
BMS1 is designed to be left ON at all times. Power consumption is minimal
and there are no moving parts that will wear with use.
Upon connecting the supplied Power Adaptor (and after a short ‘boot up’
delay), BMS1 will begin playing your background MUSIC FILES and it will
also play your MESSAGE FILES at a user programmed frequency.
MUSIC FILES in the first created Music Sub-Folder are played first on a
completely RANDOM basis, until the last file has played. Once all music
files in this sub-folder are played, BMS1 will then begin playing Music files
from the second created Sub-Folder until all files have played before moving
to the next Music Sub-Folder.
Once the last song in the last Music Sub-Folder has finished, BMS1 will
then move back to the first created Sub-Folder again and then cycle on
until power is removed or the SD Flash Card is removed.
It will also SEQUENTIALLYplay all of your MESSAGE FILES before
repeating again from the first one.
Messages can be played after a preset number of songs (01-250) or after a
preset number of minutes (0-250).
If Messages are selected to play at a fixed minute interval, then BMS1 will
automatically ‘fade out’ the Music first, before playing the Message. Once
the Message is complete, it will then ‘fade back in’ the Music from the
same point that it stopped the Music File.
The frequency that MESSAGE FILES play, is programmed via the BMS
Dealer Control Program, which creates a file known as SET.TBL, which will
be saved to your SD Flash Card.
If there are NO Messages loaded onto the SD Flash Card, then BMS1
will just play through all Music Files in an uninterrupted fashion.

FLASH CARD INFORMATION
BMS1 uses normal SD Flash Cards to store your MP3 based Music and
Messages. They must be formatted as FAT32.
Our unique loading design allows your complete Music and Message
programming (contained on the Flash cards) to be changed in seconds
and you do not even need to power the device down before doing this.
Each unit is currently supplied with a 2GB SD card, which provides for up
to 2000 minutes (33 hours) of Music or Messages at CD quality (Mono
128kbps).
You can load up to 32000 minutes (250 hours or over 10 Days) of Audio
onto the Flash Card by using a 32GB SD card at CD quality (Mono 128kbps).
Your Flash Card has Two Folders pre-loaded on to it. One folder is called
the Music Folder and this is the folder where you should store all of the
MP3 BASED MUSIC FILES that you wish to play.
The other folder is called the Message Folder and this is the folder where
you should store all of the MP3 BASED MESSAGE FILES that you wish to
play.
These flash cards are completely non volatile, which means that your
message is not lost in transport or when power is lost.
They can be over written indefinitely, without any deterioration in quality.
The supplied Flash cards are PRE-FORMATTED. Should you ever need
to reformat them, you MUST reformat as FAT32.
When reusing your Flash cards, it is important that you
‘CONDITION’ each Flash card before loading replacement Music
folders onto the card.
The BMS Dealer Control Card provides a
CONDITIONING MMC/SD CARD option,
selected from the main

National Communications Page 7
FLASH CARD
PROGRAMMER
Your MUSIC FILES and your MESSAGE FILES must be transferred to the
Flash Card using an SD flash programmer.
These Flash Card programmers can be built into your PC, or they connected
to your PC via a USB port.
Flash Card programmers are treated by the PC as a Removable Hard Drive
device.
Once connected to the PC, they are automatically allocated a separate
DRIVE LETTER so that you can then COPY and DELETE files to the Flash
Card inserted into this drive, just as you would do with any other Drive of
your PC.
The normal way to do this is to use our BMS Dealer Control Program,
which provides a simple user interface (see page 10.)
However, you can also use Windows Explorer if you wish. This application
will then allow you to ‘Drop and Drag’ or Copy and Paste your MP3
Messages and Music Folders onto the SD Flash Card.
You can load Windows Explorer by pressing both the STARTkey and also
the E keys on your keyboard at the same time.

FLASH CARD FOLDERS
Your Flash Card is supplied with Two Folders pre-loaded on to it.
Music Folder
Note : This must always be the FIRST folder that should be created
on your SD Card.
Because of the large volumes of Music that will normally be used,, BMS1
uses MUSIC SUB-FOLDERS.
Sub-Folders can have a maximum of 250 songs contained within it. You
can load up to 250 Sub-Folders, within your Music Folder.
You must load at least ONE Sub-Folder of Encrypted Music onto your SD
Flash card. You cannot load Music direct into the Music Folder.
Sub-Folders present a perfect opportunity to arrange your Music into
separate GENRE groups.
With our Model BMS1/T (Time Programmed Music and Message Play)
device, you can also program individual Music Folders to play during specific
time periods (within each day), for specific days of the week or for a specified
period (using a start date and stop date). See page x for further information.
You should arrange your Music into folders of up to 250 songs each.
Our Encryption facility will then allow you to automatically encrypt a complete
folder of Music at one time.
Our BMS Dealer Control Program will then allow you to TRANSFER complete
folders onto your SD card, one at a time.
You can also achieve this by using Windows Explorer and simply ‘dragging
and droping’ folders into the Music Folder of your SD Card.

National Communications Page 9
FLASH CARD FOLDERS
Your Flash Card is supplied with Two Folders pre-loaded on to it.
Message Folder
Note : This must always be the SECOND folder that should be created
on your SD Card.
Note : Sub-Folders are not used in the Message Folder
You can load a maximum of 250 Messages into the Message Folder.
You should copy all of the MESSAGE FILES that you wish to play, to this
folder.
You can do this with our BMS Dealer Control Program, which will allow you
to TRANSFER individual Messages (one at a time) onto your SD card.
You can also achieve this by using Windows Explorer and simply ‘dragging
and dropping’ individual Messages into the Message Folder of your SD
Card.
Note : If there are NO MESSAGES loaded into the MESSAGE FOLDER,
then BMS1 will just play MUSIC ONLYin an uninterrupted fashion.
Note : If the order that Messages are loaded onto your MMC card
and hence the order that the files will each play is important, you
MUST write them to the Flash Card one at a time. If you drag more
than 1 file at a time to a folder, Windows will load the files randomly
onto the card, in an alphanumeric fashion, based on the filename.

BMS CONTROL PROGRAM
The BMS Control Program has been developed to provide you with an easy
to use, step by step procedure for programming up your Flash Cards. You
will find this program (BMS Control Program Setup.exe) on the CD which has
been supplied with your unit. To Install this program, simply ‘double click’
this file and then follow the instructions.
STEP 1 - CONDITION YOUR SD FLASH CARD
The first step for all programming is to CONDITION your SD Flash Card. This
procedure ERASES all files from the Flash Card and then CREATES a
MUSIC FOLDER and a MESSAGE FOLDER.
Select the Drive Letter for your SD card on the first occasion that you enter
this facility. It will then be remembered during future access, providing that
the drive is not removed.

National Communications Page 11
BMS CONTROL PROGRAM
STEP 2 - TRANSFER MUSIC FOLDER TO YOUR SD CARD
The second step is to TRANSFER COMPLETE FOLDERS of ENCRYPTED
MUSIC to your SD Flash Card.
You should navigate through to each
folder that you require to be copied to
the SD Flash Card and transfer them
one at a time by highlighting them and
then clicking the Send Icon.
Note - BMS1 will only play Encrypted
Music Files, so you should Encrypt
each folder first using the Encrypt
MP3 files option from the Main Menu.
STEP 3 - TRANSFER MESSAGES TO YOUR SD CARD
The third step is to TRANSFER ENCRYPTED MESSAGES to your SD Flash
Card.
You should navigate through to each
MESSAGE that you require to be
copied to the SD Flash Card and
transfer them one at a time by
highlighting them and then clicking
the Send Icon.
Note - BMS1 will only play Encrypted
Message Files, so you should Encrypt
each message first using the Encrypt
MP3 files option from the Main Menu.

BMS CONTROL PROGRAM
STEP 4 - MESSAGE PLAYPROGRAMMING
In this section, you specify how frequently you wish to play a Message. You can
play a message after 1-250 songs, or at intervals of 1-250 mins.
The software defaults to SONGS. If you
wish to change to MINS, you should
use this drop down box.
You can also program BMS1 to play
Message at a HIGHER VOLUME than
the Music in this area. By Sliding the
slide bar to the right, you can
DECREASE the volume of the MUSIC,
relative to the MESSAGES.
There are 12 possible reduced volume settings, each position represents a
reduction of 1.5dB, providing you with a maximum reduction of 18dB.
The settings that you have made from this page are then saved in a file called :
SET.TBL, which is then saved on your SD Flash Card.
BMS1 stores this SET.TBL in its internal non volatile memory, so there is no
need to load it onto Flash Cards other than to program a new unit or to change
the programming of your unit.

National Communications Page 13
ENCRYPTION FACILITY
This facility is used to ENCRYPT all
MP3 based Music and Message files
for use with our BMS1 devices.
The Encryption process is a
demanding mathematical
manipulation of your original MP3 files
and can be quite time consuming.
Depending on the power of your PC,
this can take up to 1 min of processing
time, per minute of MP3 Music or
Message.
You should first navigate through to
the SOURCE FOLDER of the Music
Folder or Message File that you
require to be encrypted and then select
the folder or file to be encrypted
You should then navigate through to
the DESTINATION FOLDER for the
Music Folder or Message File that it
will be SAVED to once they have
been encrypted
Files that have been encrypted
are renamed with the same filename,
but the extension has been changed
from .mp3 to .bms.
Ie: filename.mp3 - becomes - filename.bms
To save considerable time and effort, we recommend that you encrypt
your Music Folders (genres) in a single run.

BMS1 INSTALLATION
when using an Amplifier
Please refer to the Installation Diagram on page 15.
BMS1 provides a Stereo Line Level output, which is designed to connect
direct to a separate Amplifier.
The separate Amplifier is then used to power the required number of
speakers (usually 100V paging/music speakers)
The amplifier used should have a power rating (W), greater than the sum of
the tapping setting of all speakers connected to it.
If higher volume is required on one or more speakers, then you may increase
the tapping to a higher W setting.
SPEAKER CABLE
You should use figure 8 speaker cable with a power rating suitable for the
amplifier which you plan to use.
You can use ‘Light Duty’ , such as 14/0.14 for amplifiers with an output of
50W RMS or less.
For amplifiers with a power rating of greater than this, you should use ‘Heavy
Duty ‘ 24/0.20.
100V SPEAKERS
BMS1 units are designed to operate with standard 100V PAor Background
Music speakers, which are typically Ceiling Mounted or Wall Mounted.
100V Speakers are designed to connect in Parallel fashion, as indicated on
the Installation Diagrams.
This means that the amplifier connects to one speaker, direct onto the
appropriate tapping of the 100V speaker transformer. The next speaker
connects from that same point, and so on to the last speaker, in a ‘daisy
chain’ type fashion.

BMS1 INSTALLATION
when fitting speakers direct
Please refer to the Installation Diagram on page 17.
Our BMS1 units are designed to power directly, up to EIGHT 100V speakers,
each with a tapping setting of 1W or less. This setting will allow each
speaker to provide clear background level audio.
If higher volume is required on one or more speakers, then you may increase
the tapping to a higher W setting, but you must also reduce the number of
speakers accordingly.
NOTE 1. You should not connect direct to these units speakers with
a total tapping setting of more than 8W.
NOTE 2. You should not connect direct to these units speakers that
do not have a 100V transformer. Doing so may damage the unit.
A3.5mm Audio Plug is supplied to provide connection of your speaker wire
to the BMS1 unit.
SPEAKER CABLE
BMS1 produces a maximum output of 8 watts. For this power level, you
can use ‘Light Duty’ figure 8 speaker cable, such as 14/0.14 gauge standard
or better .
100V SPEAKERS
BMS1 is designed to operate with standard 100V PAor Background Music
speakers, which are typically Ceiling Mounted or Wall Mounted.
100V Speakers are designed to connect in Parallel fashion, as indicated on
the Installation Diagrams.
This means that the amplifier connects to one speaker, direct onto the
appropriate tapping of the 100V speaker transformer. The next speaker
connects from that same point, and so on to the last speaker, in a ‘daisy
