Veils 2020 PCB, Version 11



Vibrance and variety in a new compact form factor

An amazing evolution of the classic quad VCA mixer, now available to DIY.

The new Veils has shrunk, 10HP this time, and it has sliders, and new offsets on every CV input which work together with the CV attenuators and exponential/linear response control to allow immense and subtle control over your VCA's modulation levels.

New opamps shave a bit off the signal to noise ratio and slightly lower the build cost, we're planning to carry both versions of Veils, some people like knobs, some like sliders, some will want both.

These super high quality PCB's are the Latest version 11 and made at a high end European factory! This version uses a high tech 4 layer pcb for improved grounding, cleaner power distribution and lower noise. Along with a full electrical test, our manufacturing partner uses an automatic optical inspection system to ensure all layers are completely true to the design files and beautifully aligned for trouble free operation, all in all, quite a substantial upgrade!


Building Veils

This version of Veils uses 0402 passives, so is not beginner friendly, more experienced builders will have an easy time, if they've built any 0402 modules already.

This module is easiest is to build using a stencil and solder paste, and reflowing with hot air or on a hot plate instead of hand soldering.

Strong magnification is almost essential when using 0402 parts, a digital microscope with a screen or usb model would be fine for placing parts on paste with tweezers, not such a good idea for soldering, the lag when the display updates can make a soldering iron dangerous, if the screen shows it in the wrong place. An optical microscope is better for hand soldering but not without it's hazards.

using 0603 on 0402 pads is also easier with stencilled paste than hand soldering, the gap between 0402 pads is very small so it's easier to bridge with excess solder or solder paste (stencils control the amount of paste deposited very well)

All that said, this is a very spaced out layout which should be easy for someone with experience to build.

Here's a Mouser Cart BOM for easy ordering of most parts and for costing your builds. Try ordering several projects at once for lowest prices.

Veils 2020 BOM

At the moment most Texas Instruments parts are showing very long lead times at Mouser, but they are coming in and out of stock all the time very quickly, if you order as normal they will be sent separately as soon as they come in, this is much easier than waiting for them to come into stock.

Veils 2020 was designed to use the V2164 quad VCA, it's possible the the new improved SSI2164 instead, which we stock, but you will need to use different part values here and there if you do this due to the SSI2164's higher input impedance, this is detailed in the SSI2164 datasheet, at the moment using a V2164 is a much easier option, if you figure out which values need changing in the circuit, please let us know, as just changing input RC doesn't seem to fully solve the issue (more saturated sound on channels 1 & 3) All the other modules we sell work fine with the SSI2164 and default part values, apart from Blinds, which needs a small number of values changing ideally (details on the Blinds page)

This Module pairs well with:

Tides 2, Shades, and Ripples 2020.
