Watts - Volts and Resistance

Hi,

I got a Fisher 514 Receiver for next to nothing, it's those Quad type of receivers. I haven't been able to get any ''free'' info on the net about it, I would only want to know how mant WPC this monster delivers.
This is what I read in the back of the unit:

535 watts / 675 VA / 4 ohm Max.

Can somebody tell me the max power output with and 8 ohm load ?

Thanks,
foxtrot

The note on the back of the receiver probably says that it draws 535 watts of AC power when it is maxed out driving 4 ohm speakers. This would suggest that its total audio output is probably about 50 percent of 535 watts, which is 133 watts. You say that is a 4-channel amp, so 33 watts/channel would be a good guess.
The 8 ohm audio power will be less...I would guess about 20 watts. All of this would be with all channels driven, so the power capability of an individual channel will be more.

Herman...Whoops...I divided by 4 instead of 2. (Confused by the quad thing). So it's about sixty watts into 4 ohms, and maybe 40 watts into 8 ohms.
