What is CAV?

CAV is very useful 6HP eurorack utility module. It's made of 2 units which can each: crossfade, attenuvert, attenuate, or be a voltage source. These units are chained together and have a 3rd output which sums them together. This setup allows a single module to perform most utility tasks in one package!

• Crossfade
• Attenuvert
• Attenuate
• Voltage source
• DC offset
• Subtract signals
• Mix 2 signals
• cross-mix 3 signals
• Amplify a signal 2x
• Buffer and mult signal in a pinch
• A mono to stereo with panning and "out of phase" capabilities

And more...

It uses big 45mm LED sliders for maximum fun and blinkenlights.

The module is 6HP and Front panel made of aluminium.

If this is all familiar to you then you should know I had a little rebrand from 49_chakras and made some much needed improvements to the original circuit.

Versions

This first batch of modules (V3.3) voltage source maximum is +- 2.5V, Future revisions will provide +-5V for more modulation control.

And the ink on the front panel of V3.3 is no where near as clean as I'd like. I've reflected that in the price until I produce some cleaner versions!

Build it

This run of modules comes entirely SMD pre-soldered. to finish the build you need 7 Thonkiconn Jacks, 2 LED 45mm sliders, a couple ferrite beads/lengths of wire, some headers, jumpers, and screws. Build Guide
