on page 7-27 in the service manual Rev 0 it says by installing two jumpers I can increase input sensitivity . They refer to the PCB as Model Crown M43197-8. The diagram is not the same as my Crown 9784 PCB.
I need to do this modification as with my mixing console I cannot obtain full output power of the Crown D-150 II amp.
Can someone please help out.
Cheers.
Garry
