Hi again,
I have two HO P2K E7A units with factory DCC & Sound, and WOW, I really like them.
The factory default for the overall sound (CV52) was too low for my taste (value 11), so I programmed it to the max - value 15. Of course this increases the decibel level of all the sounds, and I want some of them turned down.
To do this, the instruction manual states - "Set CV49 to the Primary Index for the individual sounds listed below". The next instruction reads - (Enter volume level in CV52 with "0" being the lowest value and "15" being the max value.
Of course it was easy to just go straight to CV52 and adjust ALL of the sound volumes upward, but I can't figure out how to do the "set CV49 to the Primary Index............" so as to allow me to adjust the individual sounds one by one.
Oh, I'm running a Digitrax system with DT-400 throttles.
Thank you all once again!!!!

Exactly as it says, actually. Set CV49 the way you'd set any other CV. Then set CV52.

If it's anything like QSI you set the primary index which simply points to a location. Then you set the location value. Usually if it shows primary index there would be a secondary index. I see them as a spread sheet. Set first number to the row, second number to the column, then the value that goes in the spot the other 2 point to.
Also what decoder does the P2K use? Many times you can go to the decoder manufacturers website to obtain much better info.

It's a QSI.
That's even better. QSI has excellent manuals that spell out the use of their CV's. If the op has a specific question or setting he/she needs help with ask away. We can provide the entries to make the changes.
I dug out a copy of the QSI manual and did some update reading since it came up.
To set individual volumes. You first tell the decoder which volume to set with CV49 then set the actual volume with CV52.
For Horn
Set CV49 to 0
Set CV52 the level 0 thru 15
Bell
CV 49 to 8
CV 52 to 0 thru 15
Diesel motor
Set CV 49 to 10
Set CV52 to 0 thru 15
Use manual for the rest of the sounds.
Basically for sound Think of CV49 as the pointer for the sound and CV 52 for the hammer or the one that sets the level. Another way to think of it is when you set cv49 to a number, say 0 for horn, you're actually saying " Hey Horn Listen Up" Then with CV52 you're telling it "Use volume level 8" if you use number 8.
Hi!
Once again I'm trying to make out something simple to be complicated. I will certainly add this info to my DCC notebook right away.
Thank you all for your help!
mobilman44, this is where JMRI Decoder Pro shine, when it come to adjusting sound nothing beats JMRI.

I agree with the statement just above on principle, mainly because I do understand, I do get, that the various decoder manuals dealing with hex and decimal can be confusing to some brains. I am in the middle ground, so I appreciate both sides of it all. JMRI should make short work of any CV setting conundrums.
That said, the way indexing works is this:
CV49 is the thumb that flips to the chapter you are looking for. The chapter is the index. You want the horn volume chapter.
The manual tells you to go to the chapter/index for horns, and it tells you where your thumb (CV49) needs to flip.
In that chapter is a page, and it happens to be CV50-whatever. So, you must tell the thumbing CV49 to go to the Chapter "0", and then to page ""50-whatever", and then set that CV to the appropriate range value for your horn appreciation.
If you can begin to think of it as chapters and pages in chapters, it makes a lot more sense.

The chapter works good with the volumes. The reason I try to use the spreadsheet is because of the settings that use a primary and secondary index. For those settings it is literally a spreadsheet/flat data base.
Then there are the ones that have a primary and secondary index, plus the actual CV - but those really just work the same way, set the index CVs like you would any other and then adjust the referenced CV.
