The 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 series is Mackenzie's third generation of high fidelity digital audio players. The M3 represents the perfect balance of features and quality in digital audio message repeaters. The M3 is ideal for applications requiring a wide array of duration, fidelity, channel and message quantity combinations. This includes museums, amusement parks, theme events as well as general public address installations.
