Would you happen to know if the DPN address' have changed; meaning, are the address' in the manual still current for addressing other devices within the chain. I'm using a DRC-SL as my method of communicating with the DSP, however, I continue to see "no devices" on the LCD. Also, considering that I have C2K amplifiers, which do not contain dip switches, do I only address the DSP along with the controller, and if so, how do I do that? Thanks in advance.
