Stereo Receiver - JVC RX-515VTN - Levels Adjustment Question

[RegularStereoGuy]

Thanks for admitting me to Audio Science Review's forum!



I have a question that is rather technical in nature:



Is there a way to internally balance the audio levels inside a consumer stereo receiver? Specifically, I own and and still use my 1995 JVC RX-515VTN receiver.



Specifically, I want to match the tuner AM/FM section to match the level of, say, the CD or Phono section. I understand exactly why radio is so much LOUDER than other sources, I studied air-chain, Optimod processors, and all that, and this is not a defect of mine or anyone else’s receiver or radio set.



I just want to be able to turn my receiver’s volume knob up a reasonable amount while enjoying radio stations at the same level as I do CDs, tapes, etc. Are there certain pots inside the circuit board I could adjust that would lower the Tuner, or at least, the FM volume?



I’d appreciate some input from others who have benched consumer stereo receivers, amplifiers, and such, from the 1980s through early 2000s.

Sighhhh... Another esoteric question.

I was born esoteric!

Just use the balance knob as needed depending on your source/input....

Huh?

With the exception of the phono input, all the inputs, including the built-in tuner as far as I know, go through the same internal gain stages - there's no way to adjust the volume of one relative to the others except by using the volume knob.

The phono input will go through an internal phono preamp first, but there's no way to simply make that permanently louder - to do that you'd basically have to design, engineer, and install a whole new phono preamp into the unit.
