Features and Capabilities
The Mackenzie M3 system is the most flexible series of high fidelity, multi-channel solid state digital
audio playback systems available to the industry. The M3 is backed by Mackenzie’s years of system
design experience.
The M3 retrieves MPEG (MP3) audio data from non-volatile SD Card memory, eliminating the need for
battery backup, and delivers superb full bandwidth sound quality.
The M3 is offered in the following configurations:
Model #
Description
M3.1
Single Balanced Stereo audio channel, 10 message

M3.1+1
Dual Balanced Stereo audio channels, 10 message
input selections each, RS232, wall mount package
M3.2
Single Balanced Stereo audio channel, 20 message

M3-RM-x
M3 rack mount packaging. 1U package contains power
supply and houses up to 4 M3 modules. Must be
ordered as a system, not field upgradable.
Messages are stored on SD Card memory cards (1GB included). Messages are randomly and instantly
accessible. Messages are stored as FAT formatted M3 allowing each of the messages to be of
different duration. DML also provides for replacement messages to be a different length than the
original, maximizing memory efficiency and compatibility with future applications.
Messages are stored in MPEG I, Layer III format. Composer software allows a Windows computer to
create entire programs with .WAV files then converts them to MPEG. The MPEG files then may be
copied to the a PCMCIA drive on the computer or downloaded directly to the M3 over the RS232 port
Message playback is controlled by simple contact closures or by RS232 commands. Audio outputs are
balanced and level is controlled via potentiometers. Form C relay connections are provided to indicate
that the M3 is playing on each audio channel.
The M3 offers several different playback modes to accommodate different applications. Play/repeat,
Play once per closure, Play while active, and Retrigger allow the user to customize input logic. Message
repetition and delay between messages are user selectable as well.
The M3's small size, industrial construction and the absence of moving parts makes it ideal for
automatic unattended operation, especially in harsh environmental or mobile conditions.
