JLM LA 500A Opto compressor

Design by Joe Malone of JLM this LA500A is the high-end compressor. It’s a fantastic optical compressor based on the LA3A/LA2A, this is a full ground up redesign with more features including side chain high pass filters, three selectable compression ratios, and also the new ‘Slow Attack Mode’ which is allows you to pull the threshold knob to engage a slower attack time.

The audio path has been fully redesigned for better signal to noise and headroom while still having a clarity and warmth so that it is at home tracking anything or paired on stereo buss duty. The LA500A is made so even at extreme settings is it hard to make the comp sound anything but fantastic.

These are extremely versatile compressors, and they work great on almost any source…. vocals, guitars, bass, etc. It’s a very smooth and warm sounding compressor that adds some definite heft to the low end. But given the variety of settings, it can also be very transparent, and not overly colored, even at high levels of gain reduction.
