I have some questions about audio repeaters and know I can get some great advice here. What is a good brand to buy? How exactly do you record on them? Do these audio repeaters have there own built in amp or do I need a amped speaker? Whats the longest amount of music/sound you can record on them?

Thanks so much for everyones help!

They are decent quality at an affordable price.

You simply load your files onto a SD flash memory card and insert the card into the repeater. Your limited by the size of your memory card and up to 255 individual files. They have several modes of operation selected by dip switch. They are available with no amp (SD-10), with external amp (AMP-50), or with built in amp (SD-25).
