Hi,
I recently bought a few pre-made amplifier modules for an 8-channel amplifier project (for a sound installation).
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).
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?
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?
It looks like the module has a rectifier and smoothing caps integrated, so I could potentially just use a transformer, right?
Best,
N
Haha yes, the car is the German's favorite child, and complaining their favorite pastime.
That being said, I think there's more factors to it. Keep in mind that most German cities were in ruins after WWII, and plenty of buildings have been demolished to make room for cars.
The difference in electoral systems might play a role, where a green party could slowly, but steadily gain influence.
Railway infrastructure was already quite dense before mass motorization.
A lot of money has been spend to get through traffic out of town centers.
There's probably more to it ...
