The IGS ONE LA is a photo-optical compressor, referring to the legendary solution of United Recording Electronics Industries.
Inside the device are 4 tubes with 245V anode voltage. The system is mounted on a PCB, which results in short connections inside the device, improves the bandwidth and stability. On the rear panel XLR connectors have been installed. The whole device is designed to work with a symmetrical 4dBu signal.
It is known that in the case of ONE LA the nature of the device depends on the T4B photo-cell. The original solution used the TELETRONIX electroluminescent panel, which illuminated the photo resistors. The idea of photocompression originating then is still cultivated today. IGS Audio has developed its own photocell equivalent to T4B called T4BX. The use of carefully selected components in the production of photocell, and their individual measurement and matching, result in completely repetitive sound qualities of each device.
