Edit description

Unlock the vintage charm and sonic excellence of two legendary compressors with the Stam Audio Engineering 3A-5 Optical Compressor. This meticulously crafted device is a 1:1 replica of both the UREI LA-3A and LA-4, seamlessly integrating the best of both worlds into a single, versatile unit. Whether you're aiming to capture the electric energy of a guitar solo or the delicate nuances of an acoustic session, the 3A-5 has you covered.

Hand-built with precision in Chile, the 3A-5 boasts custom-wound US-made transformers and the finest T4B optical attenuator available, crafted by Kenetek Pro Audio. At the heart of its operation, these components ensure an authentic vintage sound that can rival the originals. With the flick of a switch, transition effortlessly between the warm, rich compression of the LA-3A and the transparent, detailed dynamics of the LA-4.

This compressor is not just about nostalgia; it's about delivering exceptional sound quality that meets modern production standards. With a stereo link option, pair two units for a wider soundstage, perfect for stereo recording applications. Whether you're a seasoned engineer or a passionate musician, the Stam Audio 3A-5 Optical Compressor is your ticket to timeless sound.

Key Features:

Dual-mode operation: LA-3A and LA-4 compressor circuits in one unit
Hand-built in Chile with high-quality components
Custom-wound US-made transformers for authentic sound replication
Kenetek Pro Audio T4B optical attenuator for vintage accuracy
Stereo link capability for broader sound application
