T-420 Ultra High Grade

Glitch Video Processor

The T-420 Ultra High Grade is the latest addition to the T-420 family. It features the same core functionality as the original T-420 with some massive improvements.

It is a 12HP euro rack format module but can be used as a standalone module that takes a standard 12V input with the use of an optional baseplate.

The most notable improvement is the addition of 3 new effects. They can be switched on or off via the slide switch and the intensity can be altered with the corresponding knob. Each effect can also be externally switched with a gate source, it can do this all the way up to video rate frequencies.

FX1 - Chroma Bloom (creates washes of banding colours and high saturation)
FX2 - Horizontal displace (a feedback path that created jagged horizontal lines)
FX3 - Edge Trace (creates ringing feedback effects that trace the bright parts of an image)

There is also a bipolar CV input with a trim control, this controls the overall behaviour of the video processor and thus influences the FX listed above.

A "soft bypass" switch allows you to mix some unaffected video signal with the effected video signal to help stabilise the signal and change the flavour of FX altogether.

A wonderful addition to any modular video synth setup or a great way to introduce some synced CRT visuals to your audio modular.
