You want a flexible sound board that allows multiple sounds as well as the option to trigger them remotely by radio control or with discrete triggers? You can have up to five different sounds of any length at your fingertips. Since you determine the sounds, you have the whole Internet universe to pick from. You can also change the sounds anytime you like.
MP3 Universal Sound Module
Comes with connector cables, RF remote, micro-SD card, and USB micro-SD reader/writer.
By adding my 4-channel relay receiver to the mix, you can actually have one sound board serve four locations.
