The Professional audio player with built in GPS

Description

PRODUCT NOTICE: We no longer manufacture or sell the AM4. The DVM8500 shares many similar features as the AM4, including the ability to play .mp3 and .wav files, and trigger them from GPS cues. Please contact sales@alcorn.com for additional information.

The Digital Audio Machine is a studio quality MP3 and WAV player with all the interfaces sound contractors need for professional installations.

The Digital Audio Machine stores its sounds on Compact Flash cards, so playback is virtually instantaneous. You can create and edit your audio using your desktop PC. Then just copy the clip to the media or transfer it via the Ethernet option.

Clips may be triggered using external contacts or pushbuttons, serial RS-232 messages, Ethernet, playlists or the built-in real time scheduler. The unit can also simply loop continuously when powered. It fits almost anywhere, from dashboard to rack, and even works in high vibration environments, such as roller coasters! Power it with a 12V battery or the included AC adapter.

The Digital Audio Machine is also a terrific player for GPS-triggered transportation applications. When connected to a GPS receiver (see the accessories page), the Digital Audio Machine steps through cues automatically as it moves through user-defined geographical zones!

Alcorn McBride provides the latest firmware for your product at no charge. To learn how to check your firmware version and upgrade it, visit our Firmware page.

The Input Expander breaks out the binary inputs on your Digital Audio Machine, bringing all the signals to an easy-to-wire terminal block. It gives you direct access to up to 15 playback selections, stop, play, pause and mute. Attach the input expander to a DIN rail or even a wall. When used with a power supply it works up to 1000 feet away!

We offer two GPS Receiver kits, one that mounts magnetically, and another that is permanently installed. Both come with a harness designed to provide them with power and connect them to the serial input of your player.

If you plan to use GPS Builder’s ability to capture geographic data from the GPS receiver during programming (as opposed to just clicking point on the map), you should also order a GPS/USB cable. Since it’s just used during programming, you’ll only need one of these, no matter how many GPS receivers you’re installing.
