The AMP-1502 is a high efficiency class D

EM-21D QuikWave Audio Player

Stereo MP3, near CD quality Push Button Input: 1 Keypad Input: 3x4 matrix (optional) Serial Port: 0 Input Voltage: 12 - 30 VDC Output Power: 15W x 2 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. Operated with a single-voltage power supply, EM-21D features a built-in 15W x 2 high efficiency class D power amplifier that generates little heat. A line level output is also available for external amplification if needed. Audio playback can be triggered with a variety of methods such as push buttons, motion/alarm sensors, PLCs and 3x4 matrix keypads. EM-21D can be easily configured to work in different operation modes such as: Start to play when trigger is applied or removed. Allow playback to be interruptible or not. Play once or loop while trigger is applied. Automatically play a file at intervals. Message groups for multilingual applications. 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.
