Whilst the OP seems to be in the process of resolving the issue and, whilst it's not an acceptable fix in this case, I'm curious, would an add on power booster resolve the technical issue? Just thinking of my own set up and as I expand could hit this issue ( I'll be checking actual voltages today rather than relying on what's printed on the kit/in the manual).

I somehow ended up with two of these, hence now selling this as surplus to requirements. It is BNIB with an unopened, complete details pack and full instructions. 21 PIN DCC ready. Tracked postage included. £100.00

Works for me too, thanks. ESU Loksound 5 with SWD Sounds. F17 for my interior coach lights on/off (Aux3). F13: Cab1 lights on/off, F14: Cab2 lights on/off, F19: dim/brighten all lights

Ah, it may be this:

Thread resurrection, I know. Does anyone know what the cure is for this problem? All lights work including dimming on an ESU Locksound v5 with SWD Sounds, however, as others are reporting I can't turn off the interior coach lights unless I use the manual switch. A cut on a track on the PCB sorts it is what I'm hearing but which track and which PCB...?

UPDATE: Seems the model and its factory-fit decoder I have is not sound capable at all (some of you knew this of course). So I need a Zimmo or ESU Loksound. Again, what are folks' experiences before I buy...?

Spoken with Dapol this morning, here are the manuals: New Class 121_122 Combo.pdfDAPOL_0_Gauge_C121_user_guide_v1.0.pdf

Save starting a new thread on the same topic; what is today's best Sound Decoder for the Dapol Class 121/122 (4D-015-010D)? Or, do I even need one...? And yes, aware that the OP is just over four years old 😉 The new-to-me unit I have has the Dapol Imperium decoder (21pin MTC) which allows basic motor control and all of the coach, cab and driving lighting - it seems to do this well enough and with the assumption that standards have been adhered to, changing the Acc and dEc (Gaugemaster Prodigy) CVs have the desired effect; there is, of course, no detailed user manual that I can find. On the one-pager that came with, there is a suggestion that soldering a speaker (THIS?) to (the near impossible to solder to) LS- and LS+ joints is possible. So, is it as simple as grabbing a £10 speaker and doing as the paperwork suggests? if so, why no instructions as to how to initiate sound(s) also, normal sound functions are light functions currently so one assumes a level of function key reprogramming would be required... Alternatively, it could be that the decoder just outputs basic sounds that cannot be controlled and therefore as alluded to above a new ESU LokSound and megabasss is the way to go. Before I splash out £10 or £130, I'd be grateful for folks' experiences, please. It's a great model and with proper sounds and a little weathering, it's looking like the star of the show on my (to be built) layout. Cheers!

On hols! I'll log out and back in and see, thx so much for looking whilst you are supposed to be relaxing 😌

Now that I have acquired one, what are the DCC functions and settings, can't find anything on-line thus far. The one sheet of paper suggests a speaker can be added, I added one as per instructions but there is no sound. Perhaps I need to move up from what appears to be the standard Dapol Imperium decoder offering...?

@AY Mod still ads everywhere for me, certainly on Andriod. Please fix...

Found one.

Same for me. Following steps 1 to 4 no longer relevant as they don't work, options don't exist. Please can you sort my account, assuming I've done everything right my end. Thanks

Hi All, I'm looking for a nice DCC sound-fitted Class 121/122 Bubble car. Era 7 BR, so blue or blue-grey I guess. Thanks.
