Industrial Digital Audio Player
Our ALFTECH Industrial Digital Audio Player was designed to meet the needs for a durable and industrial quality MP3 Audio player, to provide continuous playback of compressed MP3 Audio files such as music, advertisements or announcements. The MP3 Audio Files are stored on a standard microSD Card, inserted into the microSD Card slot on the iDAP-EN1.
When the microSD Card is inserted and valid MP3 files are detected, playback will start automatically. There is no playback or stop buttons as the iDAP-EN1 plays continuously whenever valid MP3 files are available.
A configuration file, copied to the microSD Card offers the option of selecting random or sequential playback. There are 2 preset volume option settings in the configuration file; -10dBu for consumer audio equipment, and 0dBu for professional audio equipment. If no configuration file is detected the iDAP-EN1 will create one, with the default settings (Sequential Playback, -10dBu).
The iDAP-EN1 is DC powered (from external AC Adapter), but will run on the internal batteries for approx 4 hours when the DC is removed.
ALFTECH iDAP MP3 Players are perfect where continuous and uninterrupted Audio playback is required without the liability of limited-life and unreliable CD & DVD players.
Our iDAP MP3 Players are used for PABX Call-on-hold, Audio-on-hold or Message-on-hold background music, advertisements & messages to waiting callers, and as continuous background music or message repeaters for in-store music, in-store advertisements & promotions, or for background music and promotions in shopping malls & centres and elevators.
