Re: VUPPM500 KIT Build Thread
Hello everybody, have built the kit within some hours yesterday.It was easy to do and complete up to last screw. A nice project for a rainy day.... Adjustment was super-easy.Please mount the trim pots in the right direction indicated by a little slotted screw sign on the pcb.This way levels for trim...

Re: VUPPM500 KIT Build Thread
Wonderfull,Joe!
Looking forward to see the AES/SPDIF options.
Is it possible to build it analogue and add digital input-cards(?) later?
Best regards from munich,
Udo.

Re: 8 Channel Relay Switch Build Thread
Aaaaaahhhhhaaaahhhh! :D That clears it up,thank you Joe. So if we use 24vdc relais we use 24vdc as supply voltsge and put in a 7812 for the ULN 2803,right? I think confusion came from the schematics.Because the dc feed to the relais is written as „V+“ which is after(!) the regulator. I will find out...

Re: 8 Channel Relay Switch Build Thread
Thank you for the fast reply Joe. But I‘m a bit confused now. When will we use the regulator (and corresponding caps)? I understood how the control port works and would have gone to feed my dc in Version 1 exactly there-because of four linked pads on each side.In version 2 it seems to be two pairs e...

Re: 8 Channel Relay Switch Build Thread
Hello Joe, I‘ve ordered one of these kits (12vdc version),it is on its‘ way to me now. I see there are two versions now and don‘t know which one I will receive.I‘m happy with either one. Just in case it is V2: 1.:The added regulator is to add more stabilty (I‘m a bit concerned about 78xx type regs,p...

Re: Talkback Comp Build Thread
Hi Joe, if I‘m right then first things first: HAPPY BIRTHDAY!!! :D (I‘m in the same „league“) Have built it today,looking good so far. Am I right that the output is quite hot? Can you tell us a rough gain range for Rgain (from ccw to cw) with the compressor disabeled? The compressor bias went well,a...

Re: Talkback Comp Build Thread
Hi Joe, thank you for the schematics! So D9 (Zener) can be omitted,yes? It‘s also not in the BOM. Shorting it out enables the compressor whether by closing/switching the threshold connector or directly by wire. If we don‘t need the comp. we just leave it open (meaning omit D9)? Can we bring the gain...

Re: Talkback Comp Build Thread
Thank you very much Joe,
ordered some stuff some minutes ago.
Will you send the schematics (watermarked as always) with the Talkback Compressor kit?
Have a nice day,
best regards,
Udo.

Re: Talkback Comp Build Thread
Hello Joe, hope you‘re fine and had a good time at the AES.Seems some beautifull things are coming (I loved the 500 series VUPPM and the FX processor announcements!). For the Talkback Comp: 1.:I‘d like to have full phantom power because I use condenser type microphones which need full +48vdc.Can I d...

Re: dINgO Pup kit BUILD THREAD
HI Udo The dingo 4 mounting holes are not connected to the 0v on the dingo pcb unless you fit the chassis/gnd link next to the input XLR. The 2 pads under the XLR positions are wired to the XLR chassis pins but this goes no where when no XLR's are fitted. If using a floating 48v smps on plastic iso...

Re: dINgO Pup kit BUILD THREAD
Hi Joe, hope you're fine. A quick question: Should the pcbs-when mounted using the pcb holes-better be isolated from chassis? I just wonder because when measuring between the holes' metal rings and 0v on pcb I have the 10 Ohms as expected. Which is the best way,using isolated or metal bolts/screws t...

Looks like an LA500A to me,not LA500.G-Sun wrote:Now, look here
Seems like we've found the course.
Remember when soldering that this spot seemed a little weak
Fixed. Working perfect again. Thank you!
Wrong thread......?

Hi! My meter-light died. How may I replace it? Hello G-sun, the squared and the round part can be detached.Take care when doing that,gently tear them apart.No brutal force please,or you might damage the meter or bend the needle. Then gently tear apart the white inlay. After that you can reach the l...

Re: STATTEN Build Thread
Thank you Joe, 1.) Looking at the first pic,does that mean the STATTEN pcb takes ALPS RK27xxxxx series pots? I have quite a few of them. 2.) So the "pan pcb" can be directly attached the "volume pcb",yes? 3.) Talking about pan,isn't this balance instead? 4.) When do we use u-pads,when h-pads ( havin...
