A few things to check:
A) Make sure the audio switch on the HAS is set to JAMMA, not MVS.
B) Try a different PSU.
C) Remove Bandbridge from the setup and see if there's a difference. You can connect headphones or external speakers (amplified).
Just a follow up, I just moved to a new house. The problem doesn’t occur here. Not sure what was causing the issue, but the HAS is working just fine now thanks.

. The edge plastic part is quite brittle though but i rather superficial plastic sections breaking than my pcbs breaking due to fluctuating voltages. Each to their own i guess. Just saves me from having to remove it to install one thats all. The automatic sync sounds great. Put me down for 2 whenever you do another batch please.
