MRC Steam Sounder
Posted by SpaceMouse on Monday, February 12, 2018 10:58 AM

I'm pretty sure this description was written by engineers, because it took me a while to decipher.

The exclusive "Sounder" is a sound-only decoder and speaker that's easily added to any HO locomotive equipped with a standard, non-sound decoder or even any piece of rolling stock being pulled by the locomotive equipped with wheel pickups.

The railroader simply "hooks-up" two wires to the track power pickup points in the loco and suddenly can enjoy MRC's rich, Brilliance sound and the world's most extensive feature set.

The Steam Sounder reproduces eight, genuine articulated and eight, non-articulated steam locomotive sounds and you can select 33 whisles as well.

Features:

  • Use with any HO non-sound decoder from MRC or any other brand
  • Full 28 NMRA function capability
  • Select desired sounds and functions in "seconds"
  • No time consuming downloading or expensive purchases ... all the features are in the decoder
  • Use with any NMRA compatible DCC system to add sound "on the rails" or "below the rails"
  • Simple 2-wire hookup
  • Superb Brilliance sound quailty with multiple sounds and volume selectability
  • Capable of providing six dynamic lighting effects
  • 18V maximum input

So I get that there are 16 engine sounds and they are called forth on the programming track, but I have no idea if there is anything close to a 1900's 2-6-0 in the programming--although it might be cool to have an 0-6-0 that shounds like a Russsian. 

And the size of the speaker looks like it's better suited to the door panel in my wife's van than the tender of a 2-6-0, although the last one I got has a depression with pre-drilled holes that has to come pretty close. 

So, I guess my questions are has anyone tried one of these and what kinds of sounds does it make?

There no reason you cant replace that speaker with a smaller one.  That said, I would seriously boost that power supply cap.

MRC makes a sound decoder for light steam that comes without a speaker. If I forgo the speaker, I might as well get that. Hmmm.

On a different note, where would one go to get elecronic components if they live withing an hour and a half of a Radio Shack--and not have to pay more than it's worth for shipping?

Chip, Lionel placed large speakers inside of the tender on my Challenger.  They did it by cutting the plastic tube-like housing on an angle instead of at right angles the way you'd cut a PVC pipe normally.  The effect is that it canted the speaker's cone and body at an angle inside the tender when it was glued to the open face of the tube.

If you’re looking for great sounding speakers take a look at these
 
 
After installing a couple of these in my Cab Forward tenders I’ve replaced most of the speakers in my locomotives with them, they sound better than great.  One thing to make note of is they are 4Ω.
 
This is a link to my blog and the installation of a pair of the eBay 1” speakers in one of my Cab Forward oil tenders.
 
 
Most small high powered (1 watt) speakers have Neodymium magnets that are super strong so if they are placed close the track you need to protect them from getting clogged with metal filings.

I'm not sure of the signifcance. I know my car speakers are 8 ohm.

The question I have is can you fit one of those suckers in your 0-6-0 tender?

 


Crandell, that is a good idea. I'm filing that one away in my brain.

Chip,

I wouldn't use a 4 ohm as it doubles the power through the speaker which is hard on an amp.  I would at the very least cut the CV volume in half or run 2 of them in series.

So what would be a good resistance for a decoder speaker?

MRC's are usually 8 ohm, which is different than other manufacturers. I blew an MRC decoder when I tried connecting to another 8 ohm speaker that was not an MRC... You can get an MRC speaker only pretty cheap anyway (they are sold separately). And will they fit in a small tender? I installed one in a small MDC tender, but it required a little bit of grinding to remove some of the metal that serves as weight. I doubt it would fit in a sloped-tender. Personally, I would buy a new sound integrated decoder to save space. The MRC's are pretty inexpensive (although you get what you pay for).

Slope back No, Vandy Yes.
 
The MRC 1700 series dcc decoders are 8 to 32Ω, I use a 3.3Ω resistor in series when using one speaker.  I can’t tell the difference by ear using the resistor.
 
There are 8Ω speakers available in the same frame but very pricy, the 4Ω speakers are cheap.

I'm thinking the same thing. I'll get exactly what I want. Although it will cost $12 more per unit. I don't think my hearing is good enough to tell the difference between an MRC and a Tsunami. 

On the plus side, I'll have 5 more soundless decoders to add to the 11 I already have.

You can add in a resistor.  The resistence of a speaker is a function of it's frequency.  Most speaker manufacturers measure resistance at 1 kHz.  However it may go up or down dependings on what frequency it's playing.   Adding a fixed resistor throws that response off.  But for tiny speakers the difference is negligable as they sit around 8Ohms for the vast majority of their range.

I have one, but I'm away from home right now.  I can check it when I get home at the end of the week.

I put it in the tender of my daughter's Hogwarts Express, and she likes it. I have no idea what a 1900 2-6-0 sounds like, though.

 If it's like the MRC decoder I got, all MRC will be able to tell you is that there are 16 choices. They won;t be able to sya which engine you get for each of those 16 values in the CV that controls it. There's supposedly 32 horns on the one I have. There are 32 different sounds as I change the CV, so that part is true, but I asked them what horn each one was - P5, M3, A2, etc. Answer from MRC tech support: "We don't keep track of that"

 I'm no audiophile, but the difference between the MRC and some of the others is night and day. I'd rather half my locos have good sound then all of them have mediocre sound, so it may take a long time to get my whole fleet sound-equipped.

I tried to play the Tsunami but I think the mp3 file was corrupt. I tried to play it on the website and I downloaded it and still couldn't get it to play. I couldn't find an audio file for the MRC, so I'm going deaf and relying on the ears of others.

This seems more like sloppiness than anything. Sheesh.

 I'm no huge fan of Tsunamis, either. At least their diesel ones - the horns are incredibly weak sounding.

 I am now strictly Loksound, I have one Atlas Trainmaster with a QSI but that's the only sound loco I have that's not Loksound.

I'm afraid that Loksound is way out of my price range. Their programmer alone is unfathomable. 

So, what about the Sound Bug? With speakers it works out about the same as MRC and is programable with a PR3 or PR4. 

Will the interface you sent me work for this? I know the PRs will connect the computer for use with JMRI. 

Back when I was here before there was a link to the sounds avaible. Do you still have that link?

 You don't need the programmer to use Loksound decoders., you can get them already loaded with whatever sound you want.

 You need a PR3 or PR4 to load sounds in the Digitrax sound decoders. The original 8 bit ones are not so good, but the 16 bit ones are decent (the ones with the X in the model number). You have to use the right sound files - the 8 bit ones will load into the 16 bit decoders but sound extra horrible. 

Some people say they aren't very loud, but I don't know what they've done to their speakers - I tested an original Sound Bug just laying on the table, no enclosure on the included speaker, and it was easily audible in the next room.

I found the Digitrax Sound Project page and unfortunately, they have very few steam locomotives. It's possible that some of the British sounds might work, but the MRC seems to have workable sounds.

I have an old MRC decoder (0001656) in one of my 0-6-0s and it sounds right to me with the double chuff disabled, but I’m not a rivet counter either.  My only memory of a real 0-6-0 was from 1950 in the El Paso TX SP yard, I'm 80 without much stuff up there to remember with but it sounds good to me.

I'll be honest with you and tell you that no matter the manufacturer, getting a clean sounding chuff for production into a chip like this is a difficult task.  You need some expensive equipment and an ideal setting.

Given the expense, conditions, and complexity, most chips are likely just remixes of similar engines that have been tweeked though an EQ.  More bass and elongated chuffs & louder exhaust valves for super power.

I'm not saying they are all 1 engine.  But I'm willing to bet you are dealing with 2, maybe 3 engines at best remixed.  You aren't going to get dead on with operating steam being so somewhat rare.

I should say they are more prenounced which a sharper "Chuff" (stacato) cutoff which makes them sound louder.  Plus the preset sound track makes them louder compared to the other stock sounds.

Remember you are releasing more steam with a super power engine.

 I'm SURE you are dealing with a limited set of engines - there just aren't running examples of every loco listed on some decoder maker's sound lists. You can do a lot to clean up old recordings, but recordings made in the 50's on a "last chance" fan trip and sold as vinyl recordings weren't done the way they do now on still running locos, with multiple microphones to pull the exhaust from the accessories from the whistle from the turbine from the air pump. If you are lucky, it was a recording crew set up in a baggage car coupled behind the locow ith a shotgun mic. Yeah, modern signal proessing can do a lot with that but outside of distinct whistles, it's going to sound a lot the same for any remotely similar loco. And whistles are no big deal - plenty of collectors and those samples can be made seperately even if the loco it came from has long been turned into razor blades.
