Simple yet powerful SD Card MP3
Player for commercial use
Four electrical input contacts to
trigger MP3 files (15 when binary combined)
Line level phono outputs
Infra-red detector for external
USB link to update SD card
RS232 serial link
External 12v PSU
Volume, treble & bass settings
One third rack size
2 x 20w integrated amplifier The Micro Player has a built-in 2 x 20
watt power amplifier which is sufficient for most small and medium
sized environments. Its line level phono outputs may also be fed to
a more powerful external amplifier for larger premises, if need be.
Low Power Mode When a Micro Player is configured to be in
lower power mode its power consumption is less than 1mA. This
delivers long term autonomy when powered on a battery topped up by
solar energy, for example.
Optional 19" x 1U rack adaptor to
fit up to three Micro Players The Micro Player is a flexible audio
source device which can be used as a stand-alone unit or in 19"
racks. The casing is designed in a 1/3rd rack width format to allow
up to three Micro Players to be fitted side-by-side in the optional
19" x 1U rack mount adaptor.
Interactive MP3 Player for Announcements, Background Music, Commentary,
Effects and Narration
Here's a simple, robust and reliable way of
getting your message across - the Micro Player. Whilst the majority of
our solid state sound offerings are recorders designed for digital audio
acquisition, here's a device that will replay your recordings in a host
of common applications (see panel left).
The highly versatile Micro Player is specifically designed for
installations where the broadcast of sounds, music, commentaries,
messages and announcements is required either in a pre-defined playback
mode (preset) or in an interactive mode (controllable by external
devices like push-button switches).
MP3 audio files are stored on SD memory cards using any file manager
(e.g. Explorer on a PC, Finder on a Mac). A seven digit
code, inserted in audio file and directory names provides powerful
automation of the playback programme. The naming of the files actually
determines the broadcast pattern - for instance, which input starts the
file, if it can be interrupted and the next action when it ends.
Whilst audio files on the Micro Player can be triggered in many and
various ways, the most popular usage by our customers is for the
delivery of a choice of audio information at exhibitions and in museums.
Typically in these applications visitors are presented with labelled
buttons on the exhibit - these may be language choices or commentary
options - and by pressing the appropriate button they can listen to
information about the exhibit in their chosen language or their chosen
section of the commentary.
The Micro Player can make this kind of thing happen very easily and
inexpensively. Take a look at the Micro Player
QUICK START GUIDE and OWNERS
for further comprehensive details.
Playback automatically starts on powering your
Micro Player on. This is configurable.
The playback of files is triggered when one of the input contacts is
activated. An activation command (a 'trigger') can be sent using a
choice of three methods:
4 contact closures can be 'made' via a simple push button or other
type of switch (e.g. pressure mat). In this way one can trigger up
to 15 choices of file using binary combination.
RS232 serial link
Infra-red remote control
Four playback modes are available: Loop, Play Once & Stop, Random or
Pre-defined Order. It is also possible to allow or disallow file
The Micro Player's serial control function enables it to be very
In Daisy Chain Mode the serial out-Tx of one Micro Player is
linked to the serial in-Rx of the next one and so on... orders
(triggers) are transmitted in the chain of players and each player
can be addressed individually. Up to 127 Micro Players can be
controlled through one serial link.
In Monitoring Mode status data are sent to the serial outTx
(e.g. start/stop status, volume changes, USB mode, etc.). In
security situations the Micro Player's status can therefore be
monitored by a controller.
For larger systems three Micro Player units can be housed
in the optional 19" rackmount adaptor.
