/diy/ - Do It Yourself

>>1147920
sats from a panasonic system, receiver just died and I don't really want to dig around in printboards to try and fix it

it says 100W DIN(???) 8 ohms on the back, specs for the receiver are 100W 6 ohms according to the manual

I'm guessing higher resistance means less power going in? is it linear? so it'd be 1.33 times less? 75W

I'm also not sure what ohms amps are usually specified in, some say 4. so I should look at twice the wattage?

I also don't know what the relationship between watts and volume is, the volume control on the rec was in minus decibels from maximum, since I never set it to 0dB, 75W is obviously more than I need, but how would I know the wattage to go for that would let me achieve at least the volume I usually set it to before?
