EM3034A is a state-of-the-art digital audio repeater which plays both MP3 and uncompressed WAV files. It offers the benefits of both formats: smaller file size for MP3 files and better sound quality for uncompressed WAV files. Sound files are stored on a CompactFlash card for instant random access. CompactFlash cards, used in many digital cameras, are readily available in many different capacities. It is possible to store more than an hour’s worth of CD quality audio on a single flash card.
EM3034A can be easily configured to work in different modes of operation. The most powerful mode, the Script Mode, allows you to define a series of playback commands for each trigger. For example, you can play a file, wait a few seconds, play another file, then jump to another script. Or you can put the system into an endless play loop which may be configured to be interruptible or non-interruptible.
Designed to be a stand alone device, EM3034A can be powered by a single voltage supply and output to speakers directly. Playback can be triggered by a number of devices such as push buttons, relay closures, motion sensors and PLCs. The built-in 10-watt/channel power amplifier eliminates the need for an external amplifier in most cases. Should further amplification is ever needed, a line level output is also supplied.
EM3034AR
EM3034AR provides the same functions as EM3034A but adds four relay outputs for Basic Audio-n-ActionTMcontrol. The relays can be programmed to turn on/off before and/or after, but not during, a file playback.
EM3034AX
EM3034AX provides the same functions as EM3034A but adds four relay outputs for Advanced Audio-n-ActionTM control. The relays can be programmed to turn on/off at any time. The Windows-based QWAplay program (available upon request) is required for embedding the event timing into WAV files (MP3 files are not supported by QWAplay).
