Waveform Magazine Catwalk Cattenuator - DIY Build
As we tackled the Waveform Magazine Cattenuator, it was now time to tackle the new LPG/VCA. Like the previous build and the Mini Mult Catwalk, these modules take up about 12HP of space in your rack. Their footprint is small and their impact is huge. As previously stated, Waveform Magazine is on point with their Catwalk series. In case you have missed any of the previous builds or reviews, check out the quick links below to learn more.
Let’s get onto the builds shall we? Building the Catwalk VCA or the Catwalk LPG is relatively easy. The most difficult part of this build is assembling the vactrol or optocoupler as its sometimes called. An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light.
You will be putting together 2 of the optocouplers for this set of Catwalks, so turn on your iron and get ready to dive right in.
