Rob, the spec is as follows: Audioverstärker - Dauer (16mm/8 Ohm Lautsprecher im Lieferumfang enthalten) 1 Watt/ 8 Ohm hope it helps Chris
Thanks Chris, I don't know if the speaker can handle 1 watt, but it is 8 ohms, so I bet they would work fine. They work in place of the 17mm speaker that the MRC decoder comes with.
Armand, Thanks for the info on the CT sound decoder. I will have to re-think buying it just because it does not have any functions for its light signals. I might get the ESU instead, Do you have the dimensions for the ESU? Kim
Hello Kim, I surely dont want to make any promotion for ESU :angel: I will also use the SL74. On the other side if you want more stuff, the ESU ist the better choice. I plan also to integrate this into my Märklin F7 B&O, there is a lot of place in the B unit.
Hi Guy's So i think i will want two (2) of the SL74DI sound units for Diesel, and it sounds like i will need one of the Sound Progarmers to go with it. Is this right? Who makes the ESU? What is the correct model number of the small/mini loco four function decoder that everyone is ordering? I would like two of these as well Last dumd question; Does the sound decoder wire up to the other loco decoder, or are their funtions combind? I.E. do you use one decoder or two? Tony B AKA Zmon PS; Robert, please do not confuse my order here with the post left on Z central station about the same thing. what i have posted here is the same as on Z central, so only order the items once for me, not twice. Thank you very much.
I sent Oliver an email asking if he would get the sound decoders also. It looks like $2000 worth of decoders so far. Fortunately, I can cover it. I would rather take checks instead of paypal because paypal will take $3 per $100 from me. It will probably take a few weeks to get the decoders in.
Robert, as soon as you have a firm price for the decoders let us know and I'll get a MO in the mail to you. Thanks, Bob
I had sent an email asking for a lot of decoders but tonight I was testing one out, and I am having problems with it loosing it's memory, so I want to wait and test the 5 purchased last week, before committing to such a large order. The problem may be my own system, or it may be the decoder. I have another DCC system that I will setup this weekend to test with, but I don't anyone to get stuck with decoders they cannot program. My problem is when I programmed in the long address, the decoder would not respond to it. When I programmed in page mode, the verified addresses were different. One time I got the long address to work correctly, until I tried to change an acceleration CV, and the address changed to a random number. I tried resetting the decoder by putting 0 into cv 109, and the address goes back to 3, and the decoder functions fine in default mode, but that won't do me any good to have 4 functions if I cannot program them. Sorry, On hold for further testing...
Hello Robert, It's not so easy with the sound decoders, they are diva's in programming. I use for myself a modified Roco Central with ack-detector, together with the Prolok programm on PC. Without this job I had no tool to programm 3 positions CV's. Also the Esu is sensitive, he need the correct access-timing and better also a resistor of 47Ohm in the powerline. The problem with the boomboxes is that they drag a lot of current for the amplifier and like this disturb the programming signal. Perhaps you can try one time with a resistor, this drop the current and in general give better programming result. Before I forget, I will meet Oliver tomorrow
Yeah, I was really frustrated last night. That is the only one of those decoders I had on hand, so having it go flakey really concerned me. I never got far enough with it to test light functions, but it is in an AZL SD45, and I want to have a flashing beacon on top, as well as headlights and class lights. Perfect use for a 4 function decoder. I have 5 more on the way from Germany, but there's no telling how long that will take at this time of year. Tonight I am bring out my other DCC system, which is set to 10 volts. The other one is set to 9 volts, so that might be some of the problem. I will also try a dropping resistor like you suggest on my programming track, I think I read a 470 ohm 1/4 watt? Thanks, Robert
Hello Robert, It shoud read 47 Ohm, excuse me for no space. 470 Ohm would be to much, and 1/4 W is largely enough, in programming mode they just consum during information transfer. Other thing is the voltage. Even 10 Volt could be to low. Basicly the decoders were made for N scale use. So there is no problem to use for programming 14Volt, like the motor is not sollicitated. Only problem is the lights, but anyway it is mostely necessary to modify this part for digital use.
Robert, since you have problems with decoder, I desided to back out of the CT decoder. Instead, I order the Uhlebrock decoders Euro Rail Hobbies . Fortunaltly, it was in stock.
I have been corrisponding with Oliver, and he just got the order from CT for the 5 decoders I bought a couple weeks ago. At this time of year manufacturers tend to get backlogged, so things can be slow. The Uhlenbrock decoders work great, however only have 2 functions and are much larger than the CT Elektronik decoders, but the Uhlenbrock is much smaller than the Lenz Gold Mini too!
Rob, any more updates on the CT decoder you had a problem with? I continue testing mine and so far 100% OK btw mine is version 037 Chris
The one I have is certianly bad. I can get it to function by using the reset of 0 > CV 109, but I cannot get it to take a long address and keep. I have not tried to test the other 2 functions yet, but I did solder wires on the chip in preparation.
Hello Robert, Before the DX74zD was out, I planed to put the Uhlenbrock 73400 in a GP-35, but as you know this decoder is limited to 2 functions light output. On the other side it is a wonderful working decoder so I planed to put on the opposite side in the GP-35 a second decoder Uhlenbrock 73900 with four functions for marslight and so on. It is no problem to put 2 decoders when they speak the same language. (protocol+address) Just like I didn't yet try it out, so I dont know if there is place enough. For the moment I concentrate on another German sound steam loc (Jawohl :beer
I really like the Uhlenbrock decoders because they are small, and they work great. I have installed 4 of them already, and am happy with all of them. Is the Uhlenbrock 73900 a function only decoder or motor and functions?
Hello Robert, Exactly it is a standalone function decoder with 4 outputs at up to 0,6 Amp. It was put on the market at the same time than the 73400 and has also the same size. You can change some functions to blinking and also change the blinking delays. Unfortunatly they have not yet the english description on both decoders on their website, but if you find an english description of the 73400, the 73900 may not be far away. The 73900 is a lot cheaper than the 73400, here the low price is from 18$ on. Armand
