Ok, Nice setup !

Does front / rear fader work via idrive ? If not suspect that it’s only set up on the Match with the front inputs.

With the Match I’d doublecheck the audio input routing. I suspect your rear inputs into dsp is either turned down on the Match or not mapped in the routing tab. Have a look through it , check levels etc and route or increase percentage to your rear speakers only.

Test and then use idrive fader for the amount of rear speaker fill you want.

Thanks. I’m really happy with the audio quality from this upgrade. The music sounds great. But loosing the rear PDC sound is annoying.

When I adjust the iDrive tone fader to rear I have no audio at all.

In my DSP setup it sure looks like front inputs are used for both front and rear outputs.
I’m not very familiar working with a DSP, but I’ll play around with the settings and your tips in mind tomorrow.
I’ll get back with results.

Ok , take a backup before you start so you’ll have a restore point. There is lots of step by step guides on the helix / match website which is worth looking through.

Problem fixed! The routing in DSP was incorrect. Main routing was correct but virtual routing incorrect. Front inputs was used on both front and rear amp outputs.
Thanks again for your help. Very much appreciated.
