Beolab 5 - Adaptive Bass Calibration can’t complete

11 replies
Hi, i’have bought a pair of Beolab 5 and for one for one of them I can’t complete the calibration. I starts, but then it stops and the led starts to flash green. Any ideas what do? Cheers,
No ideas?
1. Try a long press of the calibration button to reset. 2. When I had BL5s, they could only accommodate 10 calibrations before they locked up and needed a Service Engineer to clear the memory. I don’t know if this was Mk1, only or mk2?
Flashes green only? Looks like it didn't store the calibration parameters. Could be a fault in a memory chip in the chassi.
Anyone knows if the IC304 is the responsible for storing calibration data?
Thanks for your replies ? How can I identify if the memory chip is broken? Is it possible to replace?
Any ideas? Cheers,  
Hi again, the investigation continues. I have tried to long press, nothing. I did try to calibrate once more:
  • The led starts to flash green
  • The mic comes out
  • Then nothing, no sound
  • The mic goes back
  • The led starts to flash red
Any genius that can help me?
Try to play the BL5. Does the lower woofer at the bottom vibrate while playing music?
