EM2220A is a rugged industrial WAV player designed for the most demanding jobs. Much like a CD player playing sound tracks from a CD, EM2220A
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 close to AM radio.
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, EM2220A features a built-in 10-watt power amplifier. A line level output is also available for
feeding an external amplifier if desired. Audio playback can be triggered with a variety of methods such as push buttons, motion/alarm sensors and PLCs. Keypads and other custom interfaces are available by special request.
EM2220A 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 another trigger or not.
- Play the sound just once or loop it till the trigger is removed.
- Sound files can be prioritized or not.
Housed in a
compact yet rugged metal case, EM2220A 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.
Automatic Time-Triggered Audio Playback
Automatic time-triggered audio playback is possible by controlling the player with an optional TMR-08 Weekly Event Timer. Each weekday may have a different program of events.
Remote File Management
When equipped with the QuikWave Remote File Management Kit the sound files can be remotely managed via wired or wireless network.
