EM-38A QuikWave Audio Player

• Stereo MP3, near CD quality • Trigger Input: 8 • Relay Output: up to 8 • Serial Port: 1 (RS-232/RS-485) • Input Voltage: 12 - 30 VDC • Output Power: 15W x 2 EM-38A is a rugged industrial MP3 player designed for the most demanding jobs. Much like a CD player playing sound tracks from a CD, EM-38A plays sound files from an SD/SDHC memory card but without the moving parts to wear and tear. The unit conforms to the ISO 11172-3 MP3 standard (up to 320 Kbps) and provides better sound quality than other MP3 players supporting 256 kbps or less. 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-38A 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. EM-38A 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. • Toggle relays in sync with the audio (EM-38AR & EM-38AX only). Housed in a compact yet rugged metal case, EM-38A 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 unit in the field when necessary. Differences Between EM-38AR and EM-38AX They only differ in the way the relays are controlled. Relays in EM-38AR can be toggled before and/or after the audio playback, but not during. Whille EM-38AX allows the relays to be toggled, in perfect synchronization with the audio, at any moment during audio playback. EM-38AM (ModBus support) EM-38AM is basically the same as the EM-38A except that, instead of the proprietary control protocol that the EM-38A supports, it supports the ModBus control protocol on the serial port.

Available Models EM-38A: no relay EM-38AM: no relay, ModBus control EM-38AR: 8 relays, basic control EM-38AX: 8 relays, complex control Downloads EM-38A/AR/AX User’s Manual EM-38AM User’s Manual Typical Applications Museum Exhibits Audio Point-of-purchase Talking Displays Audio Tour Guide Transportation Announcements Theme Park Sound Effects Warning/Safety Reminders Industrial Control Audio Feedbacks Vending Machine Verbal Instructions Optional Accessories Power Amplifier AMP-1502HV AMP-1502HV is a high efficiency class D power amplifier with a maximum output of 15W per channel in stereo mode, or 55W in BTL mono mode. Constant-Voltage Transformer HVTR1 bridges between low impedance and high voltage audio devices so that low impedance amplifiers can drive high voltage speakers, and vice versa. Digital Switch Timer TMR-08 TMR-08 is a 7-day programmable switch timer with 8 internal relays for triggering QuikWave audio players at preset times of the day, once or multiple times a day and in any order.
