The Gold Standard of Optical Compression
Vintage Optical Compressors with Tube Saturation & Zero-Latency Tracking

Teletronix LA-2A Collection perfectly models two legendary revisions of the most sought-after optical compressor in recording history. UA's circuit-accurate emulation captures every nuance of the original hardware, including the T4 electro-optical cell's smooth response and the tube gain stage's musical saturation. The collection includes both the Silver-face LA-2A (earlier, more aggressive character) and Gray-face LA-2A (later, smoother response), complete with authentic VU metering and Peak Reduction modes. Whether tracking vocals through UAD DSP or adding glue to mixes, these plugins deliver the signature tone heard on countless classic records.
