Yes, schematics are included in the documentation.

Per brief recent discussion on Analogue Heaven, the user will need to supply a connector for the desired power supply. For example, to connect to a Blacet PS500/505/PSCONN, you will need a compatible 4 pin female connector for each kit you build.

I just got my Paia modules preassembled (since work keeps me almost exclusively busy), and the power cable was pre-assembled with a Paia-end mini female 4 pin connector (same voltage order as Blacet) with 4 unstripped lead wires. The wires were about 22" long--good length for those used to the standard Blacet power cables in their racks.

I can join the chorus about outstanding price and quality, and these do represent a change from the multifunctional modules in the base 9700 kits. To be fair, the pre-amp and the envelope modules together have less functionality than a Blacet 2225 I/O, but as someone who hacked a Blacet I/0 kit for a 1U module to preamplify external inputs, the Paia 9754 Preamplifier is a much simpler solution.

Not BTW, the preassembled modules come with an updated version of the familiar Paia assembly instructions. For someone who spent many wondeful hours absorbed in assembling 9700 system kits, the "Assembly and Using Manual" brought a little mistiness to aging eyes (without the solder fumes). Fitting tribute to John Simonton and his legacy!

So these will run fine off of a PS500 correct, as long as they have the right headers???

Just got mine today. I'm not a DIY guy, and this is going to sound remarkably stupid, but where can I get the right headers, and what is the technical name for them? Can they be purchased at say, radio shack? I'd like to get these up and running as soon as humanly possible, so that I can contemplate ordering more, because quite honestly, these prices kick ass.

Do you mean the headers for the unstripped ends of the power wires to connect to a Blacet type distro board? If so, you need to look for MTA-156 type housings like this:

http://uk.farnell.com/tyco-electronics-amp/3-640429-4/housing-24awg-4w ay/dp/1098736?in_merch=true&MER=i-9b10-00001460

But bear in mind you may need a special tool to get the wires in the housing - I'm not too sure as I've never made my own.

Personally, I would think the easier way would be to not bother fitting the Paia header on the PCB, get a normal Blacet power lead, and cut off one end - then you can solder the unstripped wires into the PCB rather than having to make up a housing to connect to the pwr supply.

That's exactly what I mean. If anyone could shed more light onto this, i'd appreciate it. I'm not a DIY type, and I have no solder skills. I'd also rather not solder anything onto the boards.

I'm curious as to how you crimp a wire in those housings as well. I've got a bunch I'd like to use... very frustrating

Scott Lee @ Paia has kindly provided front panel graphic images of the new modules for use with Rackplanner. applause

I've uploaded them so they are in the Module Maker queue now.

Ahh fuck... I am pissed that these came unstriped without headers on the distro end... I ordered a AI bus board when I could have just got Blacet style headers & plugged them into a Blacet PSU...

Where can I get some small PAiA style headers???

Not sure who your local supplier is, but you need to look for 0.1" MTA/Molex headers.

Yeah I don't have a crimper... So I think I am fucked. I basicaly have to unsolder my male headers off the boards and hard wire the cable to the modules.

You don't need a crimper for the Blacet stuff. I've just strip the ends, tin them, and insert. I've never seen the PAiA joints so seriously, i just don't get it

Can anyone comment on the sound of these new Paia modules?
particularly the preamp and mixer...

When the gain starts to clip, does it sound soft or nasty (in a bad way)?

I asked ai a while ago for suggestions about this, and this is what he sent me(they're mouser part numbers):

"For instance, for the crimp-on end you could use part number 538-08-65-0816 and for the housing, you could use 538-22-01-3047, which will mate with the header on the PDB-1."

I think I used a slightly cheaper crimp pin than the one he suggested(538-08-52-0123, IIRC). You'll also need the crimp tool. If I can figure out the part number of the one I have I'll post it here.

I've thus far only powered up one of my PAiA's from the .100 headers on the PDB-1 (I was impatient and used .156 pins/housings I already had on the others), but I think the polarities on the PDB-1 are reversed from the PAiA headers(either that or I soldered the PAiA header on backwards?).

Just be careful - I did it wrong at first, but it didn't have any adverse effects on the module except not working and causing the LEDs on the PDB-1 to blink funny (how I knew it was wrong). I reversed the +/-15 on the cable and it was fine.

I don't have A crimping tool, so I think I will just unsolder the headers off the board and solder the power cables right to the units.

Crap, I may end up doing that too. Just bought a mixer and the lin/exp unit...didn't realize these weren't plug-and-play on the Blacet rack.

You could probably also tin the ends, then use heatshrink to maintain contact with the PSU distro.

One of my friends suggested that I "solder the wires right into the power supply", but that is just a bit beyond my comfort level. So here's what I did and what I got.

I got the plastic headers and the little things that go inside them from mouser, they were pretty cheap. It was mouser part number
538-09-50-3041 for the plastic header.
it's mouser part number 538-08-52-0125 for the little metal things that go inside the plastic thing. You'll need 4 metal things per plastic thing. I'm sure that there's some sort of cap piece too, like on motm or blacet modules, but I don't know WTF it is called. I stripped the wires, shoved em into the metal real good, and put them in the plastic real good. Modules work fine, but it looks like it may be a bitch to remove them from the power supply without the little cap thing that goes on top of the connector (that is, you may end up pulling the wires out by mistake if you're too forceful). This is thoroughly unscientific, i'm not a DIY guy at all, and really, I don't know what the fuck i'm doing, or if those are even the right parts for the job, but it worked out fine for me.



Have I ever told you about the time I performed an apendectomy with a rusty sardine can?

if you need some .100 MTA 4 pin female connectors I should actually have some extras, and I have the crimper as well. I could probably make some up for people if they want for a very reasonable cost. I just need to know if the Paia pinout is different and what it needs to run to.
