First post on Speaker Plans >.<

Anybody still own one of the original NJD SE-1 dub sirens, and or has a schematic they'd be willing to upload?? or very detailed shots of interior and circuitry so I could work out what they run on?? I build my own dub sirens and would very much like to build one for myself, maybe resulting in a few for sale later if it turns out well. Really like the sound of these units and want to give it a try.

thanks,

Dan.

Sorry but maybee a stupid question. Is there a mic pre amp ind de njd siren? Because of the jack input..

Date Posted: 10 February 2015 at 5:08am
There is no mic pre in the siren. Siren only. The mic input is I believe just that, a mic input.

To be fair the schematic is useless anyway as doesn't show if they are joins or if the wire is just passing underneath another wire etc. Gutted as was right about ready to start soldering a prototype and then thought ahh bugger lol. Yasuhiro please upload a better schematic!

i have a siren that will sound alittle bit different than yours and yours and yours and yours. stop copying and build something original! (no offence)..... its getting boring hearing the same siren again and again, especially when not used musically.

It had to be a man in japan who would go mess it all up. Next every man and there dog will be selling them, probably loads of really bad ones that brake quickly on strip card.

If anyone wants a decent one fully tested, in engraved metal box email info@rigsmith.co.uk

Heres a video and clip of my verson. this metal box one is not on the website yet! but others are on www.rigsmith.co.uk

I can also retune them and make random items for a little more.

I don't see the big deal, you copied a circuit, they copied a circuit. Unless youown IP relating to it then no-one is more right or wrong here.

If I was in your shoes I would just market mine as the premium alternative to cheaper units and not be concerned with the competition. Mind you I'd also probably do it as a sideline to a proper job also which makes life a little easier on the soul.

Rig smith, I like your builds. I have used a lot of them and I can't fault them. As the person who started this thread, I get the impression the whole "people like you" thing is aimed at me. Truth is I've contemplated buying yours before, however I enow building stuff as much as anybody else. All my other sirens are handbu it by me and I'm proud of them. I wanted to build the se1 as it's the only one I haven't got, and as much as I could easily go out and buy one of yours, I wanted to build my own just like the rest of them. Kind of a personal thing really, yeah I understand your a manufacturer who's making to sell, but all I'm doing is putting the feelers out there for a schematic. I'm just some lad with a soldering iron, like you put it, I'm no competition to you.

I've built my own amps, does that mean every amp manufacturer is now getting the hump with me for not buying their product??? The comment I read earluer was spot on. Market yours as the premium option for the professional market. "Don't be fooled by cheaper copies" etc and people will make their own choice. At least youd've done whatever you could

Just saying!

I am not aiming anything at anyone other than the guy in Japan who posted this. Next the Chinese will be knocking them out in their sweatshops. 

If you want, Send a message to the website. I will sell you one not in a expensive metal box and give you support to re home it in your own style unit. I have done it before its no problem. I just don't want to give out my drawing which was a pain in the ass to get. My one is in fact double checked against Alpha Omega siren with the help of my pal Ben Alpha because the clones I was given had mistakes, it took me like 1 year to get a working copy and many favors from friends. 

my board is a tidy module you can lift it out easy. Its very simple to do, last guy I even offered him to send the unit to me if he had any problems and I would fix it (he though he has his working no support required because of the minimal wiring inside my units)

I am also building them in biscuit tins and other random boxes for people who have no electronics knowledge when they ask.

Just saying!

I'm always amazed when people come on here bragging that they are an electronics designer with a good reputation and don't need to do this for a living as they are better than this etc. No offence but it's only a mickey mouse siren that was originally meant for installing in public address systems to warn people people about emergency alerts and when to go home!! OK mickey mouse is a bit strong but it's is not like trying to copy a TB303 or a Moog. Why would a designer of any repute try to 'hide' his design of a 'cloned' njd siren?!Wacko 

Just like when people where trying to make the perfect clone of a 303 in the mid 90s the general result is that you get a lot of people producing a load of farting noises all over their productions with these cloned boxes - and not even in any musical form of timing!LOL
I don't understand why you would get a noise box that sounds like a next man because the whole point of noise/siren box (IMHO) is to be signature for your sound - not a next mans but hey - each one to their own.....

Dubs just do ya ting my yoot! I will always encourage anyone who wants to build their own equipment. So long as you follow general health and safety (for your own benefit) then it's cool as far as I'm concerned.

Let's not get this thread all scoop-ish. This is the ROOOTS n CULTURE area after all.....

Guidance n protection

p.s Just seen the re-post by Rigsmith. Nice one!ClapThumbs Up As Jacob Miller once sang it's all about each one teach oneSmile

ps, sorry if I sound like a grumpy git sometimes. reggae is and has always been my passion. Its a creative playground for me. it got me into building an amp, siren, speaker cabs and riddim to bust on it!
 
I love hearing/seeing the creative input by other people. It inspires me.
 
Keep it up
 
Love

In facts its not even a 100% copy.
If you check the schematic, and also the siren from the Japan guy, you`ll see that he has more switches/buttons the the NJD.

Also the transistors are not the original ones, even if that is not affecting the sound.



just my two cents, this happend long time ago in the soundsystem buisness, JTS is a clone of the NJD with a Sirene generator IC added.

Lincoln has cloned the Links SEG 1, and so on.

Hi,
the transistors does affect the sound...i've tried a lot of diferent combinations, from old germaniums to classic BC's...  depending of the transistors, the overall style is still an njd but...with a particular colour and  response in the shapes...
also there is some easy improvements and bendings to do that offers new sounds to have an "unique" siren...pots instead of selectors...etc etc....
like Rigsmith it tooks me lot of time to draw my own schematics, i opened and cloned a tubby's and a dubsonic and make my own mix from both...  i started to experiment with transistors because values were erased on some "commercial "pieces i opened...
for me an "online" shematic is a good thing bacause now we'll see some new improvments of this classic killer siren... even if the Japanese schematic is not the same than mine in some points ,i'll build one to see the diference...
last point, i build those for my personal pleasure and sometimes for very closed friends...
here is a link on one of mines:  https://www.youtube.com/watch?v=lvAB_gq7inw

rigsmith, you're simply ridiculous.
You act like you own NJD siren secrets and things but this is not.
Be respectful even with China. Yes if China will copy will not be a tragedy.
You think you are the best and this is fair. But be respectful with others.
You clone, We clone, They clone.

Just like yourself Rastan I decided to sign up for this forum and comment only on this thread because I was a bit emotional. Someone was telling me this on Facebook winding me up while lots of other stuff was going on in our lifes. Sorry. 

We wish to Remove all our comments but its not possible. 

This thread is from 2015 and people want to keep bringing it back to attention. 

As Professional engineers we rarely get personally involved, Sorry for coming here and airing views. Big mistake.

Copy copying copied. Copy my bins. Copy my amp. Copy my pre. Copy my tops.

Where the hell is an original sound system now??????

Copy me flippin valve amp.

Listen to my riddim. Copy that too. Lots of people with no imagination. Go to a dance and feel ire. Don't have any respect for someone elses originality, just copy up dem style.

And then feel empty. Buddhists call it "hungry ghost realm"

Hi, this his my first post on this forum but i'm a long time reader. I'm rench also so excuse my bad english.

Just to say, I build my own sirens, delays, spring reverb and pre-amp (not finished yet), can't wait to start looking at amps and bins, so there is still some originality, at least an attempt. And not a single clone, of course certain things can't be reinvented but anyway I prefer figure it out myself and learn things than just copy.
And I can't understand why a so called "dub siren specialist" can't make a siren without the schematics from another guy... 
And all the difficulties about making a copy, that's a joke right?

red eye,vibesmaster,russ d  were the best copys  

recent probaly dubsonic 

i think rigsmith and mr law are ok attempts but the tone is missing in my opinion

but good work same way

The rigsmith I used was slightly off key, which might seem picky, but actually makes a big difference when playing with music.
Best siren I ever used was a Red-eye (although my current one is absolutely bang on, Thanks Ben Reverence sound😁)
