Switching to battery power

George, I find this post odd.

I can understand if the logic circuit for the input switching get low voltage, it could send it into random switching between inputs.
But it's the heatsink creaking popping noises, that’s much more worrying, because the correct bias is all important for the amps safety.
Anyway like I said 1st post, it’s not a good idea to have "varying battery voltage" powering unregulated sections in the audio chain, as they are adjust to a certain voltage for optimum performance, and that is 99% of the poweramp section of integrateds, like this one probably.

Cheers George

I have never heard ASR but a friend whose opinion I highly respect on these matters says it’s the best sounding integrated out there.

Yes but they can go crazy, and that heatsink cracking and popping is the bias going nutz, very dangerous.

 

When the battery supply gets too low, weird things begin happening, like the inputs start switching on their own making the music go back and forth between glorious and blah. The Direct no longer is Direct but Input 5, even though the lights indicate it is Direct. The amp is susceptible to weirdness when the heat sinks suddenly pop and crack at random intervals and scare you with low level music

Cheers George

Only good if the equipment you intend putting on battery "has voltage regulators for every stage of it’s design". Then everything stays as the designer calculated for it to work optimally.

If no voltage regulators are present then the circuit design parameters will over under voltage depending on battery charge, this is not good for sound as the circuit/s will not be working optimally
