Hello!

Posting on the off chance that somebody has some knowledge that will help with a very specific problem. I have a 2019 Jaguar I-PACE with the 380w Meridian system that was the base option in the US. Since updating the software over the air last December, the system has been applying an aggressive and annoying dynamic process that sounds like one of those automatic volume leveling features (to compensate for road noise or speed or whatever), only my system doesn’t have that feature, and if it did I’d expect to be able to turn it off.

The effect is in place on all sources. I’ve tested it with a sound file I made with bursts of white noise at various levels. What I get is lots of quick dynamic compression above about -15dB (digital scale), coupled with a gradual but very aggressive boost (across 4-6 seconds) of anything down around -35dB. Depending on the music going on, this goes from mildly distracting to barely listenable. It happens at all listening levels.

I haven’t been able to persuade my dealership to flash and reinstall the software. Meridian support referred me to Jaguar. Jaguar says everything is fine, without saying whether they’ve really understood the problem. So I’m stuck.

Does this sound familiar to anybody? And is there somebody who has some kind of secret bat phone to Meridian where I can get some more detailed technical information about what kinds of DSP stuff these systems do and why they aren’t user addressable?

Thank you!
