EM-38air QuikWave Audio Player

• Stereo CD quality WAV/MP3 • Contact Closure Input: 8 • Serial Port: 1 (RS-232/RS-485) • Wi-Fi TCP control • Output Power: 15W x 2 • Remote content management EM-38air is our top-of-the-line audio player designed for the most demanding jobs. Much like a CD player playing sound tracks from a CD, EM-38air plays audio files from an SD/SDHC memory card but without the moving parts to wear and tear. The device can play CD quality WAV files (44.1KHz, 16-bit) and MP3 files with bitrates up to 320 Kbps. Audio playback can be triggered by one of the following ways: • Dry Contact Closures (push button, motion sensor, PLC…) • Serial Port Control (RS-232/RS-485) • Wi-Fi TCP Control The built-in Wi-Fi interface provides not only TCP control but also content management such as file upload and deletion. Powered by a single voltage DC power supply, EM-38air features a high efficiency low heat class D power amplifier with thermal and short circuit protection (automatic recovery). 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. Housed in a compact yet rugged metal case, EM-38air can be easily secured into place with supplied mounting brackets. Wiring is done via screw terminals and requires only a small screw driver. The screw terminals are detachable, making it fool-proof to replace the device in the field when necessary.
