Hi all,
first of all I have to mention that I love the whatsbestforum! A lot of helpful information been discussed amongst people who share the same lovely hobby
Why I am reaching out (issue): I received my DUO XDs last night and installed them right away. They look great and also sound was good from the start! After listening for approx. 1hour we were about to leave and come back later, so I was switching off the gear. Surprisingly I recognized then that my stereo power amplifier Burmester 911 MK3 was freaking hot!!! Until then nothing was recognizable, it was playing fine and It did not switch off or anything like that.
Which gave me a little shock honestly and never ever happened before, while previously, I was driving it much heavier with bigger volume with my other pair of speakers (89db efficiency 3-way ETON chassis treble ER4 + mid 7inch + bass 11 inch). The maximum there was a bit of casual little warmth after 4-5hours of continuous listening...
Later same night, I plugged in my other speakers again and the 911MK3 it was playing fine w/o any temperature - kind of business as usual.
I tried another time to run the DUO XDs (connected as per manual means preamp > power amp > via speaker cables to mid range input > via jumper cablse to sub/treble inputs) and the 911 MK3 started getting hot again immediately after ~5mins!!
I am puzzled honestly as I connected everything as it is explained in the manual from Avantgarde as well as Burmester - see attached pictures. Also the DUO XDs should not demand any relevant power from the power amplifier as they have the active Bass Modules and the external amplifier only needs to drive the Mid/ Treble as far as I understand.
Has anyone a clue or idea why this happens and the 911 MK3 is getting hot after 4-5mins?
What's happening? Thanks a lot in advance for any helpful guidance here everyone!!
Kind regards and a great start into the weekend everyone,
Frederik
