Great idea, anyone know of NL8 equivalent?

Why would you not just solder them? The less connections in a van to go wrong the better.

Have to agree, connections like this are ok if you are regularly taking things apart but surely a soldered joint is better in every way.

I have similar from NJD cabs. Has the board but then you solder on wires.

The speakons are soldered in - the idea of the links on the PCB is to save the 'hassle' of soldering in 4 short links and trying to solder two wires onto one speakon pin.

If you're good at soldering, I guess its not so bad, but I have seen some proper messy soldering jobs with people trying to do this, and failing, with straggly strands of copper shorting across pins and the insulation creeping back from too much heat exposing excess copper.

The idea was just a quick, easy way of linking across all 4 pins of the speakon without the mess and hassle.

The APEM connectors are rated at 24A, and they are the clamp up type, so the U clamp is pulled up to tightly clamp the wire in a similar fashion to many mains connections. This connector was selected as it has proven to be reliable. There is also a notch on the PCB so you can attach a cable tie for strain relief.

The screw terminals are optional - if you dont used the terminals, there are 4 large solder pads that will accept 2.5mm wire (possibly just 4mm if you're clever) and you can just solder on the wires you need. I agree, unless you are changing regularly you dont need screw terminals - this is why these are also available as separate parts and you can just make them without screw terminals if you want. 

Let's suppose you have a sub on pins 1+/1- and you want pass through on pins 2+/2- you can solder 2 speakons on to the board to make your links, and then just solder 2 wires in for pins 1+/1- to go to your bass driver.

It makes the soldering much, much easier, and gets the whole job done quicker.  If you're a pro solderer, this may not benefit you much - it's aimed more at the amateur who has trouble with soldering speakons and wants an easy option.

If I was knocking our a production run of say 20 boxes, I would also welcome being able to get the tedious task of soldering speakon dishes done quickly without losing too much time on it. Time = Money

I estimate you could solder the speakons on in about 30 seconds once you have a hot iron - you'll probably spend longer waiting for the iron to heat up.

These only arrived Friday - we'll get some soldering speed tests done and see how quick they can be assembled.

how much power would you draw through the circuit board?

We calculated the tracks can safely take 25A - we used a standard online calculator which takes into consideration copper CSA and surface area. Where the tracks are wide (12mm) the surface area is large which keeps temperature rise down.

The tracks are only 55mm long, and at 12mm wide, probably wider than the tracks on many amplifier PCBs.

Calculated resistance pin to pin through the copper is 0.001 ohms, and at full 25A,  power dissipation through the tracks would max out at a whopping 0.5W.

Time wise realistically to terminate 2 x speakons in to a cab linked with all 4 pins heatshrinked done in a way its going to be the same in 10 years is easily 15-20 mins. By the time you have prepped the cable Tinned it, cut heat shrink to fit etc.

So if speed is what your after these would be great. But in terms of Longevity soldering is key.

Also as Andy says if your a Billy Crack hands with a soldering iron these would suit ;)

If you want solder, you can have solder all the way:

Feck, and there's me with a box of speakon sockets and another box of dishes... Any chance of selling the PCBs on their own?

I've used identical connections in Vieta (Spanish) boxes, except the sockets weren't Neutrik and soon lost their ability to lock. Dead easy to set up though.

The PCBs are a fixed spacing for a specific dish - if your dishes have the holes at 55mm spacing, then you're fine - otherwise, you need a custom PCB.

Hmm, I'm measuring 54mm on some dishes from your good selves, but that's with powdercoating. Pins'll probably flex enough. One way to see for sure...

54/55 within 1mm should be fine.

There is a little play on the PCB of approx 0.5-1mm

fastons will still have a place, there are people who like to use the NL4MPR and rebate them directly into the back of the cabinet.

This is just ONE solution, so many different ways to do this, and loads of different dishes - this fits ONE type of standard dish.
