PAC-PDLC81 line converter, blender and aux Muxer... Too good to be true?


Any thoughts?
I'm liking the idea of being able to switch the amps to an aux input with the push of a dedicated dash-mounted volume knob... and the ability to push the 8ch outputs I need from the 4ch inputs (line level from factory head) without rca splitters...

Quality of PAC digital signal devices?
Have a better idea for $100 bucks?
