Audioguru; Actually I bought it for the case. Its in a nice waterproof case.Would you buy an audio amplifier that has absolutely NO SPEC'S?? And you do not know who made it?
Is its output 20 whats or 20Watts per channel? At what distortion and for what frequencies? Maybe a horrible-sounding 10% distortion at 1kHz and much more distortion at higher frequencies?
If it uses the circuit shown in Philips datasheet and the power supply voltage shown there then it is a fairly good amplifier. BUT WE DON'T KNOW.
The data sheet was a little hard to find. The TDA8922 looks good. Who knows how the amplifier was designed.Are the TDA8922 chips any good?
I get datasheets from www.datasheetarchive.com where you can select it from any manufacturer you want. I usually select the manufacturer who invented a device, not a copycat manufacturer.The data sheet was a little hard to find.
I think that's only when you use the mute pin, but I don't know for sure.And it boasts of:
"No switch-on or switch-off plop noise"
