TDA7293Pro
The
TDA7293Pro is a basic module for converting passive
speakers to active. On board is a Balanced Input with
it's own voltage regulators for the Op Amp.
With
a Balanced system, a group of active speakers using
the TDA7293Pro can be used to provide quality Background
music in restaurants, places of worship, fashion houses,
etc.
