London Acoustics - Brighton Opto Tube Comp is a custom-built, versatile compressor with strong character. It can be slow and smooth like a classic RMS Opto with normal settings or push it to extremes and it is very capable of some snappy ‘pumping’.
It is based on a classic Vactrol VTL5 optical photocell detector, a custom-built one, coupled on a breadboard with a new-concept, custom-circuit tube preamp designed by V. Realacci of Sound & Light (in Formia, Italy).


Brighton Opto Tube Comp, with its modern tube compressor concept, is well suited to a wide range of applications, especially for vocals (even with a high amount of gain reduction), lead lines, bass, and drums - short attack and recovery are very interesting.

Also using it in buss or master buss with moderate settings can be pleasantly surprising.
The attack and recovery times are, in this machine, quite fast compared to other similar compressors thanks to the use of a very fast type of LED source.

Brighton Opto Tube Comp is capable to retain a good amount of low-end even at a high level of reduction and 100% wet signal, but if this is not enough, it also features an internal sidechain to allow the user to set the low response at the preferred level.
