Hornby TTS sound vent van

Recommended Posts

Simple query - how do you adjust the sound volumes on the van? Mine are far too loud and as such the van is not being used. I have tried altering the cv/cvs according to the information sheet supplied cvs (the sheet suggests lowering the overall sound by changing CV 190 but elsewhere on the sheet it says CV190 is not readable) but using the NCE PowerCab on a programming track does not make any difference. I recall having read somewhere that the cv numbers allocated to the TTS Vent Van are misquoted in the information sheet but cannot remember where. Cheers.

it is not necessary to read back a cv to change it ( although some controllers which expect to read back might 'hang' at this stage.  ... in which case either turn off read  back or change to PoM .... for which  it will not expect readback, and can be done on any part of the track

Simply write the new value to the desired cv    .... eg  CV190 ... write in a value of 0 = all sound off!!!   or 1 for quiet   4 is factory default (on other locos)

try the numbers used for disels or steam locos....  cv182 for an s15    or   cv182 for an 08  or cv178 for a castle

failing that simply type in a range .... start from eg cv160 =0  through cv161=0, cv162=0 etc until you hear a result.

then reset sounds with cv8=5 to default and change (again) only what you need.

Tried with cv190 again - did not work. will try your other suggestions. Thanks.

I'm not aware of any issues with the CV for the volume being misquoted on the information sheet for the Vent van.

I've just checked mine and CV190 is definitely for the overall volume.

 

Have you tried programming it on the main? Set one sound playing then try changing CV190 to 1 if after exiting programming on the main the volume decreases then you know it has taken the new value.

 

Using my Powercab, I've just tried mine on both the main and programming track and the volume changes using both methods.

 

All the sound levels are controlled individually by CVs 160 - 189, with CV190 controlling the overall volume. 

Try changing the volume on CV161, this is for the air spanner and is on F1, if this gets louder or softer as expected then try one of the other CVs and see if the volume changes on that.

 

Have you tried resetting it by writing CV8 with the value of 8?

 

If the volume still won't change I would suggest contacting Hornby for help.

Thanks beejack. Will try again though have tried most of your suggestions. The PowerCab does work changing cvs on loco decoders so the handset seems ok. I have installed two Gaugemaster/TrainTech rural sound modules which work well so if I cannot reduce the sound volume on the vent van so be it. It will end up sitting silently in a siding as a condemned van.

As suggested do a full reset by writing value 8 to CV8 or value 5 if you just want to reset the sound section.

Sadly neither of above made difference. Ah well. If this was a TTS loco I might be marginally more agitated but it isn't and I ain't. Thanks for the suggestions though.

If the problem is YOUR CONTROLLER NOT programming without having any feedback - then simply place another DCC loco next to it - do the programming, and the loco provides the acknowledgment - then remove the van and programme the loco back to what you wanted on that.

If this is the solution - its one reason why I always prefer to use a Multimaus without readback to program locos !  (The Multimaus WILL support readback when used with the Rocomotion Serial interface or with a MultiCentralePro or a Z21/z21 )

The TTS van has a hefty wattage resistor connected across the ‘motor’ terminals so that it can be programmed by any controller.

 

 

There is one make of controller (forget which, Dynamis or PA) which says it has programmed on the screen but is tardy in the actual task, so give it a long few moments after it says it has done it for it to actually do it.

To be honest I do not really want to mess around with the cvs I have set on my locos in case the "...b*gg*ring up" curse rears its head. The vent van does work but is just rather loud. It does not really matter in the end - there are worse things in the world sadly - but I may try stuffing some sound-proofing in it. Thanks for all the suggestions. I note that no-one has suggested jumping on it or of using the time-honoured male standby technique of banging it with a hammer though both thoughts have briefly crossed my mind.

This will probably be my final comment on this. Took the vent van to my local model shop and tested it using their Gaugemaster Prodigy Express and, once again, the sound volumes could not be adjusted. At least it confirms my PowerCab handset is ok. Next step - contact Hornby perhaps or have a chat with  DCC specialist. We'll see.

I know I said the above would probably be my last comment  but just to keep you up to date - after returning from the model shop thought I would try again and attempted to change individual sounds. Well knock me down with a large sausage - it worked!!!!!!!! This does my head in as we went through the individual sounds in the shop and it had no effect. As I said knock me down with a sausage. However even with individual volumes reduced to 1 from 4 it still seems too loud for my layout. Some people never satisfied eh!

if you wanted it quieter you could experiment with speakers. Wiring two 8 ohm speakers in series would give 16 ohms and would reduce the volume

Oh dear ......no it won't.    It would give a 4ohm impedance and possibly smoke from the decoder !!!

SERIES connection is needed to ADD 8 + 8 = 16.

And if the c v volume control is not proving sufficient reduction .... And wadding is not enough ( still allowing for cooling airspace) then a resistor in series would be more effective than adding another loudspeaker ....and occupy less space too.  And probably cheaper.

Sorry it was late, I meant series! Glad you spotted it!
