Panasonic SA-Xr10

Does any one know if it is possible to set the xr10 to that it is able to play in 'bi-amp' mode by using 4 of the amp's channels to drive a pair of bi-wire speakers? Does this need re-programming of the chip?

I tried using it in 'party' mode, but it did not soud right?!

What other mods have been tried on this amp?

Cheers
Peter

you can use the analog inputs to route signals to the different channels.

supposedly there is a 10 ms delay between the front and rear channels in party mode. i haven't tried it yet.

if you want to biamp with a digital input you will most likely need to mod the box.

Hi draughwurt,

Thanks for the input, but the 10ms delay makes the music sound disjointed. It also works from the digital in. I am happy to modify the box/chip, but need to know how. Is there a way to eliminate the 10ms delay?

well the factory default is 50 ms, so if you haven't changed it yet maybe 10 ms will sound better to you. without using the dvd-a analog inputs the only other way is to directly pump i2s singles to the surround channel amplifiers. shouldn't be too difficult, but I would suggest ordering the service manual. you might also want to read some of brian brown's posts in the digital amplifier thread you posted to. there is a lot of good info there.
