EM-34A is a rugged industrial MP3 player designed for the most demanding
jobs. Much like a CD player playing sound tracks from a CD, EM-34A 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-34A 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-34A 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-34AR & EM-34AX only).
Housed in a compact yet rugged metal case, EM-34A 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

EM-34AR: 4 relays, basic control

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
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.
