The AI-net cable has 8 different wires in it. I think 4 are for 2 channel analog audio, 2 for power and ground and I think the last 2 are for digital communication. I don't think the AI-net cable can transmit any digital music. That can only be done with an optical cable.
As far as controlling the H701, you can tweak the EQ, etc... as your listening to the music. The only time the music will be muted is when you switch presets. That takes a few seconds and the music output goes way down during the change. It's still playing, just at a really low volume.
It also mutes when you switch between R or L and R & L for EQ.
Been in contact with an individual who has the schematic but that can't release it. He's able to upgrade the 701 per my requirements, but I'd still like to learn a bit more about what's going on in this thing.
I have added an RUX-C701 to my system to allow me to select between the inputs on the PXA-H701. Unfortunately, I do not see an "INPUT SELECT" option under the "Setup" menu, which is supposed to be there per the H701 instructions.
I am guessing this is because I am also using a DVA-9861 Head Unit which has the ability to control the PXA-H701 and is connected via the Ai-Net cable. I have tried the DVA-9861 set up in "normal" mode and "EQ/Div" mode. I have also tried connecting the Ai-Net cable to the CD Changer input instead of the Ai-Net input. The next step is to disconnect the Ai-Net cable and run RCA and Remote Start cables separately, to make sure that it is really not trying to control the H701.
Does anyone have an RUX-C701 who can see the "Input Select" option? If so, how is your system set up?
OK, nevermind the above question. I confirmed my theory. I disconnected the DVA-9861 Ai-Net cable and ran a remote-on wire instead, and PRESTO!!! The "INPUT SELECT" option is now available. This means I have to run RCA cable from the front to the rear instead of the Ai-Net cable, but that will work OK. Hope this information helps someone else.
I don't understand, you should be fine using the AInet cable. If that is all your running (input wise), why do you need the input select menu? Are you also using an optical cable?
