We can supply this Comp as a 51X version. If you want 51X version please mention this in the comments section when checking out.

• LA500A Opto compressor is our MAC comp in an API500 series format. It is a full ground-up redesign of the LA3A/LA2A type compressor with several extra features. We have kept all the audio oddities of the side chain to keep the compression signature and extreme compression depth but added extra ratio of 5:1 to 10:1 and side chain HPF switching FLAT, 100Hz & 200Hz so the low end can be fully compressed or removed from the side chain to let the low end breath and make it easy to balance the compressed sound.The audio path has been fully redesigned for better signal to noise and headroom while still having clarity and warmth so that it is at home tracking anything or paired on stereo buss duty. The LA500 is made so even at extreme settings is it hard to make the comp sound anything but fantastic.
