The Anthony DeMaria Labs Opus-3 is a solid-state optical compressor inspired by the LA3A. It shares the smooth levelling and ease of use that made the original so legendary. 

The Anthony DeMaria Labs Opus-3 includes the same  optical cells found in the SCL1000. These optical cells are hand matched to create unique soft knee compression characteristics. It also ensures  a level of consistency and reliability required by professionals.

The ADL Opus-3 is a "set-and-forget" compressor thanks to its program dependent controls. It is as a result ideal for tracking or mixing vocals or bass guitars but also in live use or broadcast. Small sets of controls are provided with the main controls Gain and Peak reduction doing most of the work. A Compress/Limit switch offers a choice between a gentle 3:1 ratio or heavier setting of 8:1. The VU meter can display the output level or gain reduction amount by switch the GR/Output switch.

Additional controls not found in the original LA3A include a Normal/Pad switch. It attenuates the XLR input gain to the audio transformer by 14dB to avoid distortion or clipping. A Stereo/Mono switch lets you set the unit as a stereo or dual mono (when connecting two units together). For true stereo operation settings on both units must have their settings matched.
