Pittsburgh Dual Index (Dual VCA) Multiple luma and chroma keying

luma and chroma keying

allowing the pedal to produce a unique type of gated

The gain reduction is controlled by an extracted DC signal from the Envelope Follower

This makes it perfect for those self running

The RA-1 accommodates all Analogue Systems modules that have just one power socket at the module end
