TDA7293PSU is an ALL-IN-ONE module for professionals
that want an easy and quick solution.
board is a complete power supply. All that's needed
to get it up and running is a power transformer. Simply
solder in the secondaries and that's it. A 8A Bridge
rectifier with two 3,300uF 50V filter capacitors supply
the power to the TDA7293 as well as the Op Amp. To
ensure the Op Amp has clean supplies, two voltage
regulators (7815 and 7915) are deployed.
cater for professional use, the input is fully Balanced.
For domestic use, the input can be converted to Single
TDA7293PSU is compact enough to be enclosed in a 2-way
speaker for active speakers. The pcb footprint is
only 4-3/8" X 2-3/4".
is outstanding. The TDA7293PSU recorded a Rise Time
of 2.8us with a 20kHz Square Wave into an 8Ω
More than that, she sounds very "musical"

TDA7293PSU is one channel and is supplied
Unassembled. Two kits are required
complete the amplifier, the following are
1) a power transformer
2) a heatsink for the TDA7293 chip amp
3) a metal case and the necessary connectors
