Hi,\n
\n
I recently bought a few pre-made amplifier modules for an 8-channel amplifier project (for a sound installation).\n
\n
The amp is based on the TDA7294 chip and is rated 85W nominal. Now I’m looking for a power supply, but I’m a bit lost (this isn’t really my strongest field, to put it mildly).\n
\n
Do I just need to add up the output power, 8*85W = 680W, or could I get away with using something smaller, like a 300W or 300VA?\n
\n
Also, the seller said that you need to use CV power supplies, CC won’t work and kill the circuit. Does that mean a switching supply can’t be used?\n
\n
It looks like the module has a rectifier and smoothing caps integrated, so I could potentially just use a transformer, right?\n
