I have an email into Pinnovations for help too.

I have had their Sam Stern kit installed on Metallica for quite some time. It's plugged into a Polk sub and works very well.

Getting ready for Iron Maiden, I decided to hook up the mixer. Installed it as recommended and no bass.
As per instructions, have cable from machine going into pink connector of mixer and cable from mixer green output into subwoofer.
checked all connections a third time. Adjusted the pots on the mixer as instructed and nothing. No sound.

Can I use this as a stand alone unit until Maiden gets here or is it not working because it's only hooked up to one machine?

Thanks in advance.
