The LA-4 is one of the UREI legends. Unlike the FET-based 1176, it’s an opto compressor with a relatively slow attack & release. Overlooked for years, the LA-4 is now achieving collectible status

The LA-4 has an unbalanced input and a transformer-balanced output. Gain reduction is via a Light Dependent Resistor (LDR) which is paired with an LED driven by the sidechain. The result is very linear, distortion-free compression with dynamics typical of an opto device – relatively slow time constants and correspondingly warm & likeable compression. It has a character very different to the 1176 but, like other models in the UREI range, it’s infinitely useable and appealing



Standard 2U rackmount compressor. Switchable 110 / 220 Volts. Power input via captive power cable & new UK power plug. Input & output on barrier strip. Pigtail loom with Neutrik XLRs and Mogami cable included
