Gunbird 2, Psikyo PCB

[Panther]

Hi!

I'm new here and just start with a question

I own a Egret 2 and run Gunbird 2 on it recently. But there is a very high frequency sound for few seconds when i start up the cab and after every stage when the character is shown (only with marion i notice that anyway) and when i turn the cab off, there is a "crack" from the speaker. the high frequency sound comes from the speakers, not from the monitor.

But thats only happen with Gunbird 2, all other pcb's run fine. I bought it from japan and it looks original to me, with stikers so on
Is there anyone can set up that to check if its normal on this board?

Thank You so much

I own a Gunbird 2 PCB for my Egret 2 and I've never had any of those problems, although the sound has to be turned up pretty high to hear it. So when I switch between the Cave boards and Gunbird 2, I have to be sure I turn the sound back down after I remove the Gunbird 2 board and pop in a Cave shooter or it blares the heck out of my Egret 2 speakers.
