<{POST_SNAPBACK}>Right, a quick install has been completed, my thaughts about the 158 sound chip are thus.
Firstly, upon starting up and while the loco is stationary, with the two 20x40 ml speakers in the one coach does make it apparent that the sound is only coming from one "end" or unit.
It is far less apparent when the unit is moving though.
I think I will try another set up by taking one of the speakers into the powered unit. There was not allot of room in the powered unit, so it may mean using a smaller 23 ml speaker or perhaps removing one of the drive shafts and having only one bogie driving.
F0 controls the lights, I have done the simple DCC lighting as I don't need separate head and tail lights, my 158 will only run in 2 coach formations and not be double headed.
F1. Start up and shut down. The start up and the shut down sequence are both much shorter than on "proper" diesels, the 158 takes just a few seconds
Although I have travelled on many 158 I cant say I have ever heard one start up or shut down. The sound is crisp and sharp, it does remind me of a bus though!
Horns are nice, you have a single and a double or you can combine them for single+ double or double + single, so in effect you get four variations.
With the 158 we also get door release. Its very good and although short, is the full amount of time it takes on the 158 I believe. The only problem with it is that once the door opening sound has been made you expect the doors to slide back and hoards of little people to walk out!
Air brakes
We get two air release sounds for the first time ( I think) on a SWd chip. The first is the shorter air release that is the sound made as the brakes are applied. Authentic class 158 brake squeal also comes on, the setting of with can be changed in Cv for lots of squeal (which I like on the 158) or less squeal ( my usual setting on loco classes)
The second air release is a recording of the sound made when the air brakes are released while at stop. This sound is longer and softer. Together they give a nice play factor to the operation which for me is what sound is all about compared to the far less realistic non sound models!
As with the HST and class 67, the 2 minute chips have been available since December 06 and SWD have been able to include top end notching as well as the low down sound speed range of sounds. The notching on the 158 sounds "top notch!"
"Its the way I tell um"
Notching up is very impressive, especially at the top setting when the engines are flat out.
Like wise there is notching down.
For me notching is taking a bit of use to get used to, though I have to say it is superb when you get the hang of it. At Calne MR show in January my stationary class 67 was a real crowd pleaser just going up and down the notches. It does give a new dimension to operation making it all the more realistic.
I think its safe to say that all future SWd projects will probably feature notching if at all possible.
I don't like DMU's really!
I have 2 x 158 (although I shall be getting the arriva 150+158) and a 153 and the truth be told I only baught these for use on my layout (Rimenough) when at exhibition, so punters could see something other than light engines. Now of course they can hear something different! On a run, the 158 sounds great. This clip
was done using a LH 90 handset, something I am not too used to using. I think I would have more control with my more familiar lh 100 handset.However, it hopefully gives you an idea of how good a DMU can sound!
You have Aux 1+2 which can be used for tail lighting should you want it, though I think combined with the door release sound the express lighting door open lights would also be worth considering.
Love it just love it and I agree with you the sound certainly makes a huge difference. I think it spoils you for the others without sound but then from 'you tube' I see you have the odd one or two done anyway! I have a pair of 20's with the sound and they are brilliant but one of the guys at the club has a SWD 31 which he is a bit dissapointed about as it is not very loud. He has only the single speaker as supplied with the decoder whereas I went for the larger oval ones. Have you found the 31 quiet? Did you remove the fan to fit yours? I thought he could leave the round speaker where it is and put one of mine taken from the 20 decoder and place it in the battery box/fuel t\nk underneath. Any thoughts on that?
