Looks like you need to adjust your HC settings to make the high frequencies louder.

You can fit these hearing aids by using PFG 8.6c. You can intro your audiogram in Audiogram, then in Instruments select Classic. In Type of fitting select Classic family BTE anf fill other options. Then in Proposals try Show other instruments and then select Super-Front PP-C-L-4 +. In calculated you’ll find the settings for the trimmers.

I suppose that SSPL must be MPO, Low Cut must be LC, High Cut must be HC and Gain must be G.

I know this topic is too old. I wish I could have answered on the date of the topic. Also I am sorry for my English.

Try this, I use HC to increase high pitch to number 5. But it is very, very loud. I would keep it down halfway on the volume level. I like it higher for music as playing instruments in which very important for me for sound clarity in a quiet room but conversation, I keep the volume low like 3 out of 10. Here is my adjustment for my poor low pitch sound.
