Turning sound down on a decoder

Postby aldothenoo » Tue Mar 06, 2018 12:04 am

Hi I have a bachmann class 108 dmu with a Mr soundguy sound decoder in it which is fab but a little loud. How do I go about finding the right CV to change the volume down ? Can anyone offer any assistance on this if someone out there has the same decoder or similar. Thank you Alan

If it is an ESU LokSound decoder, the volume is on CV63. LokSound v4s use values between 0 (no sound) and 192 (loudest).

For the record, for anyone with LokSound v3.5 decoders, the CV is the same (63), but volume values go between 0 and 64.

If your decoder is a Zimo one, Alan, then the CV is different, but I'm not sure off the top of my head. I have a few Zimo sound decoders, but will have to look up the 'cheat sheets' to find the volume settings.

Having had a few of these (class's 101 & 108) it's always quite a surprise how loud the standard 20x40 can be when it points down but when pointed up as in the class's 20, 37, 47, 55 etc just how quiet the same speaker can be. Obviously in the DUM's it's using the empty carriage as it's sound chamber whereas on the others because the chassis is in the way there is no effective sound chamber.

On a Zimo the master volume is CV266
