Urei LA4A

Great pair of Urei LA-4 compressors! The metering is not perfectly matched between the two, as they were not original matched pairs and need to be recalibrated if you're looking for that. However, they sound great and no issues besides a scratchy pot once in a while! Working perfectly fine in my studio still to this day. Upon acceptance I will remove them from the rack mount and can take better photos if requested! 

"The Urei LA-4 is a single channel compressor / limiter in half-rack format with very simple controls for input/threshold and output gain. Ratio control and meter function are selectable on these same two knobs. Attack and release times are not controllable.

The LA-4 used op-amp electronics and saw a couple very minor circuit revisions through its production and cosmetic changes. Blackface and silverface versions are largely interchangeable when properly serviced. The LA-4 is a very popular platform for modifications to expand its bandwidth and speed up the slew-rate of the audio electronics.

The rear panel features a high/low sensitivity switch and terminals for input and output connections. Later versions (post 1980) featured rear connections for stereo coupling."
