The AMP-1502 is a high efficiency class D

EM-21D QuikWave Audio Player

Stereo MP3, near CD quality Trigger Input: 1 (keypad/push button) Relay Output: 0 Serial Port: 0 Input Voltage: 12 ~ 30 VDC Output Power: 15W x 2 or 55W x 1 EM-21D is a rugged industrial MP3 player designed for the most demanding jobs. Much like a CD player playing sound tracks from a CD, EM-21D plays sound files from an SD/SDHC memory card but without the moving parts to wear and tear. The player supports the ISO 11172-3 MP3 standard (up to 320 Kbps) and provides better sound quality than other MP3 players supporting 256 kbps or less. Powered by a single voltage DC power supply, EM-21D features a high efficiency low heat class D power amplifier with thermal and short circuit protection (automatic recovery). The amp can also be configured as BTL (Bridge Tied Load) for power boost in mono applications. A line level output is available for external amplification if desired. Audio playback can be triggered with a variety of methods such as keypad (3x4), push button, motion/alarm sensor and PLC. EM-21D can be easily configured to work in different operation modes such as: Start the playback when the trigger is applied or removed. Allow the playback to be interruptible by the next trigger or not. Play the sound just once or loop it till the trigger is removed. Automatically play a list of files with user configurable delay time. Up to 10 groups of separate audio files and system configuration. Housed in a compact yet rugged metal case, EM-21D can be easily secured into place with the integrated mounting tabs on each side of the unit. Wiring is done via screw terminals and requires only a small screw driver. The screw terminals are unpluggable, making it fool-proof to replace the unit in the field when necessary.
