The Nova has just a pre-amp output. There are also 2 analogue inputs (In the area labelled Analogue Inputs), one on Din and one on RAC phono. I’m not sure what this section labelled “AV” is that you are seeing…
Look on the other side and you will see an Analog output with phono and DIN connections. That section is labeled A/V for audio/video. Normally, that means the Nova supports Passthrough bypassing the Nova’s volume control. It that is the way the Nova works I can connect it to the pre-amp section of the SN2 and use it in place of the amplifier section of the Nova.
Some early images of the Nova (during the long delay between announcement and actual release) showed different input/output sockets from those on units that were actually released, so I wonder if that is where the confusion lies?
I tried to use a 5-pin DIN from the Nova to the SN2 and the A/V DIN connection on the Nova wouldn’t accept it. I suppose that’s why the manuals only show RCA Phono connections. So the answer is it won’t work. I’ll have to wait for the NDX2 to try the SN2.
You could try running the Nova Pre-out into a Unity Gain set input of the Supernait 2. You would then be using the volume control of the Nova and effectively bypassing the Supernait’s pre-amp when set to the Nova’s input.
My dealer just confirmed what I thought was wrong with my demo NDX2, the DIN analog output of the NDX2 is defective. The problem has been turned over to Focal. It appears the problem occurred during shipping.
