Has anyone got the plex v3 knock monitor?

Im not finding it the most user friendly to use or set up.

but when using as audio only im struggling to hear anything. Full volume in head phones under earmuffs but as soon as the car is under load im unable to hear anything even on max volume.

any ideas?

Cheers Sam

Make sure the frequencies derived from bore size are correct.

Try second harmonic order as well.

Are you using headphones with a 3pole TRRS plug? Many of the common 4 pole earbuds with a mic wont work
