Pioneer AVIC-n1, SDV-P7, and 12disc chang

I currently have the pioneer Avic-n1 installed and also installed the pioneer SDV-P7. They are hooked up via the IP-bus cable. There is also a pioneer 12 disc changer hooked up to them also via IP-Bus everything is fine and great but the audio from the dvd player SDV-P7 is really quiet compared to the radeo and disc changer and also anything else I have hooked up like a gamecube. I have crank up the volume for the pioneer SDV-P7 player. Anyone know why this might be. Ive tried changing everything around and double checked all connections. Its just not nearly as loud as everything else. It sounds fine if I crank it up but then if I switch audio sources I get my doors blown off. hahah Thanks Nick

I have the exact same problem.

I have contacted pioneer and so far I cannot figure out why its so quiet.

I called pioneer and they dont seem to have a solution for me. I notice that the sound is much better if you go through the audio outputs but then you loose control of the unit through the ipbus. Nick

Page 84 in the operation manual speaks to the "SLA" source level adjustment. Touch the SLA button in the Audio Menu and hit the + to raise the volume.

had the same problem with mine when i had it installed in my last car with the avic-n1, just adjusted the sla and upped the volume on the avic and ran main volume through my deq-9200
