An example of how life isn't always that fair Helmut. Recommended for bravery with one hand and seemingly recommended for the sack with the other! All part of the blame game and compensation culture era I suppose.
Juergen sent me a photo of his new experimental sound rig. It transmits sound by Bluetooth. We have exchanged quite a few eMails on the subject. Juergen has also now tested the 'impedance convertor', which I also recieved today. Juergen & I have also both now ordered a 'reverberation' board. This will add 'ambience' to overly 'dry' sounds.
I thought getting my head round "layers" in my photo management software was a brain basher but this takes the biscuit! Looks like the route to the canteen at a cheapskate holiday camp - round in circles so you never find it but see lots of distractions on the way!
The converter is directly connected to the speaker outputs of the sound module to transfer the amplified speaker signal into a line in signal for the low pass filter and a bluetooth audio transmitter. The sound module is fed by a separate DelTang Rx65, that works in parallel to a Rx in the loco.
Si and his profound knowledge of audio electronics helped a lot with this.
Maybe I find time at the weekend for some sound impressions.
Yes he is from Tamiya. It's a loan from a friend for some pics. Difficult to get nowadays.
I will introduce my figures in my 7/8" figure thread later on. But recently I concentrate on the Toeffelholm Sound installation.
This is getting way too technical for a simple 'ole country boy like me.
Here's my sub-baseboard sound system; all I need to do is wire in the Tsunami somewhere :
For the deeper wheel rumble sounds I might fire up the Hartke 3500 hybrid compressor amp but the 2 x 4 x 10"s + horns will have to go downstairs in the lounge. That'll give the neighbours something to listen to !
Built in echo, reverb, chorus & delay - way to go !
Interesting looking cab design Si. No reflex, no baffle.
"T.S.E.C." ?? - never come across them, whose their Agent ? One of these fusion, world music ethno collectives I suppose ?
I've found that it's quality vs volume. For studio quality low frequency richness, definitely a 15" Eminence or similar. For working gigs where the kids want noise, shift some air with multiple 10"s - it ain't exactly Mozart that's going down.
Now how do I wire a Tsunami chip into a Fender ? Regards, Michael.
Ps: "return" on an IPad doesn't work in aiblue, no problem.
So you are not far away from my recent test setup. At the moment I use a guitar amp/speaker combo.
To connect the speaker exit of your Tsunami to the line in of your amplifier, you will have to use a high/low level or impedance converter like the one Si has introduced a few posts ago.
As your Tsunami Sound decoder is a pure DCC device including motor control, as I suppose, you have to connect it to your DCC control unit and program it on the same address as the DCC decoder inside the loco, if that is possible. Or you program the two DCC decoder like two locos in double heading.
But I have only a very basic knowledge of this DCC stuff. I tried DCC control about 13 years ago before I start using RC-control for trains.
Very effective Juergen. Being in the DCC camp, I've absolutely no knowledge of RC (other than what's been written on here and much of that has gone over my head!) but RC and sound don't seem to be a problem.
yes DelTang works with sound, but from the technical boundary conditions of DelTang and and of sound modules that are not dedicated to DCC alone, this was never a problem.
But please, that's not the topic here. This sound sample shall be a contribution to Si's "Replicant" aproach, using the parts Si has introduced here to feed an under layout sound system, and to send sound wireless everywhere you want by a bluetooth device.
And that will work with any sound source. It's a Phoenix sound controlled by DelTang in my case, but will work as well with a DCC Decoder/Sound placed apart from the loco or with a MP3 player or SD card player that is fed with your own loco sound or with an ambient sound of e.g. a harbour scene.
So Bob, size of a sound module doesn't matter, because it is placed outside the layout as I have shown in the "sound box" picture some posts above. In case of a small layout you can go with an under/over layout speaker(s) alone and drop the bluetooth part if the bluetooth receiver doesn't fit inside the loco. I can give you the measurements of the bluetooth receiver if you want.
This is the Bluetooth board which Juergen has used in his critter.
There are numerous Bluetooth receiver boards around.
This one has a BUILT IN amplifier, of 3W+3W (some don't).
It is available on eBay for $2 a couple of bucks, inc. P&P.
The dimensions of the board are 40mm x 24mm.
It requires a 5-Volt power supply.
Which could be derived from a 2-cell LiPo battery.
Using a simple & cheap '7805' (or similar) 3-pin Voltage-regulator.
I am investigating an EVEN SMALLER option or two at present as well.
