Helix PP40 Info

Hello, I own an Audi A4 B7 (8E) and I am using an Helix PP40 amplifier. Does anyone have information about additional options for this amplifier? The instructions that came with this amplifier do not include its full capabilities.

Thanks for your help Kaufi.

I tried to download the file in the link but I dont know what program is used to open a file an extension .af2.

I have the PP40 with DSP.

My questions were:

1. How can I make the PP40 turn on an external subwoofer amp that is not canbus?

2. My rear speaker do not play any sound when the amplifier is connected. Could this be a result of the setting on the amplifier? The cable that was supplied withthe amp had the connections for front and rear speakers.

I really like that PP40. Its has a lot of options and I would like to see all the capabilities of this DSP AMP.
