Used UREI LA-4 Compressor

The Urei LA-4 Compressor is a vintage solid-state optical compressor/limiter known for its smooth, musical compression and studio-grade reliability. This unit features straightforward controls for threshold/ratio and output level, along with a classic VU meter for monitoring gain reduction. This example shows visible cosmetic wear consistent with age, including surface scratches and patina on the faceplate, and has been modified with hardwired connections on the rear instead of standard XLR I/O. It is fully functional and ready for studio use.

The LA-4 is prized for its fast, clean response compared to tube-based optical compressors, making it a great choice for vocals, bass, and instruments where you want controlled dynamics without sacrificing clarity. Its simple interface makes it easy to dial in everything from gentle leveling to more assertive compression, and it sits well in both tracking and mixing environments. A true studio classic that delivers vintage tone and performance.
