EM-2220A QuikWave Audio Player

? Mono WAV, AM radio quality ? Trigger Input: 20 ? Relay Output: 0 ? Serial Port: 0 ? Input Voltage: 12 - 30 VDC ? Output Power: 15W (mono) EM-2220A is a rugged industrial audio player designed for the most demanding jobs. Much like a CD player playing sound tracks from a CD, EM- 2220A plays sound files from an SD/SDHC memory card but without the moving parts to wear and tear. The file format support is 8-bit uncompressed WAV files with sampling rate up to 22.05KHz. Although the sound quality is not as good as our MP3 players, it is adequate for most voice playback applications. Audio programming for the unit is as simple as copying sound files to the memory card via a card reader attached to the computer. The type of memory cards used, the SD/SDHC cards, are most popular and readily available in a number of capacities to suit different needs. Hundreds of tracks totaling hours of audio can be stored onto an inexpensive card for instant playback. Powered by a single voltage DC power supply, EM-2220A has a built-in power amplifier to drive speakers directly. Audio playback can be triggered with a variety of mechanisms such as push buttons, motion/alarm sensors and PLCs. Once triggered, the unit can operate according to user configuation in different modes such as: ? Start the playback when the trigger is applied or removed. ? Allow the playback to be interruptible by another trigger or not. ? Play the sound just once or loop it till the trigger is removed. Housed in a compact yet rugged metal case, EM-2220A 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.
