MP3 Node Hardware Installation and User Guide
9000-0000-127 Revision 01 7 of 21 Genave Electronics
Overview
How it Works
The MP3 Node is a stand-alone MP3 player which has 8 independent inputs (Channels)
which are used as triggers to play 1 of up to 255 different MP3 files stored on a microSD card,
or to play 1 of 8 internally stored files. There are actually 16 channels but only the first 8 are
available as external inputs for user interfaces.
Each MP3 Node has an output port which is used to control an external amplifier.
The MP3 Node has the ability to change the acoustics of the MP3 file by altering the volume
treble and bass.
Additionally, the MP3 node has a microphone input which can be used to record MP3 files as
well as be used for Live PA messages.
Each of the 8 external inputs has 3 different audio files that it can play:
1) When an SD card is installed, the unit can play an MP3 (SFX) file that begins
with the same number as the input… i.e. Input 4 (Channel 4) can play “004-
Hotel California.MP3”
2) When there is no SD card installed, the unit can play an MP3 file that is stored
in its internal memory that is associated with the input.
3) Play an MP3 file that was created with the microphone that is associated with
the input….. i.e. Input 4 can play “MIC-004.MP3” (Requires SD card)
There are methods to associate any of the 255 MP3 files on a card with any input. This is
called “Masking”. This user guide is a beginner’s guide and does not delve deeply into
masking. For more information see “Custom Source”
When one of the 8 inputs is triggered (Pulled low to pin 9 of the input port), the unit looks to
find which audio file has been assigned to the input (SD card file, Internal SFX file, or
Microphone file). The Node then turns on the external amplifier, waits for a short time to let
things settle, then it begins playing the MP3 file out of the amplifier port. At the same time, it
plays the file out of the “Line Out” port, but the line out audio is raw audio. It has no volume
control nor treble and bass adjustments.

Inputs
This determines what type of input will start and stop the
channel.
DISABLED: The input does not perform any actions.
TRIGGER: The input activates the audio when it is turned on.
The input may remain active or be turned off at any time, but
the audio will have been started and will run to its completion.
HOLD DN: The audio runs as long as the input is turned on. It
will stop when the input is turned off or when the audio has
run to its completion, whichever is first.
CANCEL: The input will stop currently running audio.
Source
Selects which type of audio will be played.
Note: The letter X in this group is filled in with the channel
number currently being edited. The example to the left is
Channel 2 which would make 00X-* in below descriptions
actually be presented as shown. In this instance it is shown as
002-*.
00X-*: Use any MP3 file beginning with three digits (the last
digit matching the channel number) and a hyphen as the
fourth character in the name.
MIC-00X: Use MP3 file beginning with the work MIC- and the
following three digits (the last digit matching the channel
number). MIC- is a reserved keyword which the MP3-NODE
automatically assigns new microphone messages.
ALERT-2: The SFX alert sound assigned to this input.
CUSTOM: An MP3 selected by browsing the SD memory
card. The name does not need to follow the 00X- naming

Power Connection
The MP3 Node operates from 7.5VDC to 28 VDC. The power input is also reverse voltage
protected. The polarity of the connections is displayed on the label.
Microphone Port
The Microphone Port is used to create MP3 files for storage on the SD card as well as a
store-and-forward PA function. Use only Genave 8032-0000-004 microphones. The
microphone is biased with a 5 Volt supply.
MP3 Node Hardware Installation and User Guide
9000-0000-127 Revision 01 20 of 21 Genave Electronics
Line Out
The “Line Out” port is a direct output from the MP3 player. Line Out is not buffered.
It does not go through the final amplifier, hence the volume of audio from Line Out cannot be
adjusted. Line Out is to be used for testing purposes only.
Amplifier Port
The “Amplifier Port” is specially designed to control a Genave amplifier type but it can control
other amplifiers as well. There are two control lines (Power Up and Mute) and a 600
Ohm isolated audio output.
The Power Up line is pulled low before the audio begins. Power Up is used to control a relay
or mosfet which in turn supplies power to an amplifier. The maximum voltage controlled by
Power Up is 60 VDC and the maximum current passed by Power Up is ½ Amp.
When the MP3 Node is playing sequential files, Power Up is kept on for the entire run.
The second control line is “Mute” which is used to mute and unmute the amplifier between
sequential MP3 files.
Both control lines are active Low (Mute = 0 and Power Up = 0)
The 600 Ohm output has a DC resistance of 58 Ohms. Do not apply and DC voltages to the
audio output.
