Sung's bi-amping system

[Sung]

Reading back over the thread, it sounds like you are using the same configuration file on the Master and the Slave. Perhaps I've misunderstood, but it might be the reason why you are getting sound from the Master (left channel) but not from the Slave (right channel).

and downloading the same fw and config file "of slave" on slave SD card. Sorry, I missed the word "of slave".

Yes, I didn't think you'd made a mistake with your files, but it was worth checking. 
Sorry you didn't get the bi-amping mode to work.

I am now very happy to say "finally I made bi-amping mode of my 1000pro and sound so wonderful".
However I have doubt about firmware download and download custom config files to 1000pro. Because I did repeat the download fw and custom config files then by chance I got the successful result of bi-amp mode of 1000pro. I just repeated the procedure of the same fw and config file download, there were no other new try and suddenly I got the expected result. This is why I can not explain how I got successful result and just doubt of unstable Devialet hardware or software.

Anyhow bi-amping 4x250W sound so good which is much better than dual mono mode 2x1000W.
Anybody who own dual mono Devialet should try bi-amp mode.
