strda 1200es feedback through speaker B when not connected


Prominent Member
Hi tried asking in the amp section but that just looks like recommend me an amp section.

Hi i have just noticed that i get output from my tweeters if speaker B button is pressed.

Sony STRDA 1200ES with MA br2 bi amped, i can do the test tone on the speakers when on speaker A and all is fine i do the test tone on speaker B and all i get is output through the tweeter, this is with nothing connected to the speaker B terminals on the rear of the amp.

If i am on speaker B and do the test tone or for that matter any output i get audio through the tweeter but as soon as i switch bi-amp off it stops

Is this correct or am i missing something (i have had this since new and just noticed it)
