Altering Sound Volume On Dcc Fitted Loco Which Is On Analogue System

Hi all,
If you have a loco fitted with an ESU or Massoth sound decoder and it is configured to run on an analogue system, is there any way to alter the volume ? Obviously on DCC you would change CV63 but on analogue is the only option to fit some sort of potentiometer ?

Cheers
 
Yes a dial/potentiometer is the only way, but then on massoth you'd have to alter CV63 to 255 to accept the potentiometer..

If CV 63, then you must be talking ESU..
The volume CV for Massoth decoders is CV 200..

I do not know the ESU product (other Forumite along in a minute!), but on the Massoth units you either set the volume with CV 200 ( 1 - 63), or set it to 255, and fit an external potentiometer. - Which just plugs in.

**You are sure there is not a potentiometer already fitted somewhere, aren't you?**
 
Not directly helpful here, but I do like the feature on my QSI decoders where you can have a reed switch mounted inside the body somewhere convenient, and you use a magnet to trigger it and cycle the volume to the level you want. Very useful. I place a tiny red dot to mark the position of the reed switch, otherwise I'd forget where it is! (especially given my locos are now out of use for the foreseeable future)

Now that is a good idea..
I could do something similar with a pair of reeds for Phoenix Sound cards. - Usually have a biased centre-off switch for external volume.
 
Actually on DC, you can do volume up and down from the "Quantum Engineer" from QSI, and also sold by Atlas.

You can see the volume up and down buttons...

Some other posts in this thread seem to say that the only way to alter the volume on analogue is to fit a potentiometer. Fitting a potentiometer will work and will give you an easy way to instantly adjust the volume without having to play with CVs, but just setting the volume CV 63/200 to an appropriate value should work as well.

If you don't have a way of altering CVs, take it to a mates who does, or a dealer.
 
Thanks guys. I recently sold an ESU=chipped loco to a fella who only runs analogue and wanted to convert to battery -hence the question.
 
Not wanting to open another huge can of worms, but if the buyer is planning to use a DCC-chipped loco under battery powered R/C then he will have to think it through VERY carefully, as feeding PWM power from an R/C speed controller into the DCC sound decoder will be a problem..... I would suggest he looks at the very long thread about alternatives to the Massoth DRC300:
https://www.gscalecentral.net/threads/anything-else-that-will-do-what-the-drc300-promised.299347/
.....and especially Cliff's (very successful) experiments with the Tam Valley DRS gear and a Stanton Radio Cab transmitter as a "radio-control dead-rail DCC" solution.

There has been no mention of it not working since it appears to be built and shipped to the customer.

I'd say either program it to max volume and add a pot, or invest $150 in an NCE powercab system and program the system volume as per normal.

In my case, I'd opt to the second choice, but it's up to the owner, pro's and cons to each approach.

I think that one or the other of us has mis-read some of the earlier posts, Greg - I took it to mean that an ESU-decoder-equipped loco has been sold to someone who currently operates on track power DC, but is now thinking of converting to battery R/C; hence my note of caution in my post no.14. You seem to be reading it as the loco being sold already converted for battery operation, which may be the case - but if so, I'd be very interested in hearing details of how it has been set up for that while still using the ESU sound decoder.
