Hi! I have the same problem on my pm8500, even on controlSpace they ask me the password? Does someone can help me?

FYI, I had access to the amplifier, but after the update of the firmware with controlspace over USB, it suddenly ask for a 5 digit code


Do you have an answer to solve the password problem?
I have a pm8250 just bought.

Best regards


Hello Chris

Joining in to say we’ve had the same problem and need to reset the password on a PM8500.
Lock is both on the panel and USB via ControlSpace so can’t seem to reset it from there either.

There is a thread about the PM4500 password recovery.

I have the same request for a PowerMatch PM8250 (only version with USB) which is locked and the customer has forgotten the password.
I can’t get any further with Controlspace Designe.
Can you tell me how to unlock it?

Kind regards,

Hello dear ProSound Community,
I have a Bose PowerMatch 8250 with USB.
Unfortunately there is no password for it.
I have already tried to reset it with the ControSpace Designer, but unfortunately it does not establish a connection.
Can anyone here help or provide support on how to reset the code?
Many thanks in advance for your help. :pray:
