Analog trimmers adjustments

I have a phonak PPC 4. There are 4 adjustments on it. SSPL, G, LC, HC

What does each setting control?

I forgot to write down the numbers I had on them before. I ended up with a new mold since my old one was whistling and I was trying to increase the power fr the new mold and somehow messed up my adjustment

Right now the low sounds are overpowering and I need to increase the higher tones. My voice sounds real deep and people’s voices sounds hollow and low on phones.

Which setting do I need to use to compensate it?

I found a website that might be helpful.

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.
