Q: I got a D22 with no delay or no output on Right out, neither analog nor digital?
-Audio is OK when bypass.
-The unit works fine without the ExRAM board and the jumper R291 removed.
Answer:
This answer apply to D22 with double delay option* only
(Showing 2 times Delay at power-up).
This problem is most likely due to a defective ExRAM board.
The TC order code for a replacement board is: 720018311 Fast Ex.RAM service PCB P12902-3
Alternatively, suggest the customer an upgrade to "4 x Delay time". - Please refer to D22 Service Note 2
