The Retro Sta-Level is a single-channel compressor that has 40dB of available gain reduction. While the standard version ships with 6BJ6 tubes, there’s another option that comes with coveted 6386 tubes. Regardless, the Sta-Level comes with a 6386 socket in case you want to run a 6386 with the 6BJ6 tubes. There’s also an RCA connector so you can connect two or more Sta-Level compressors for stereo, surround sound or sidechain operation in tandem with the optional stereo link panel.
It’s possible to make internal and external adjustments to attack and release. There are three attack and release settings: Single, Double and Triple. Single creates slow attack and release and changes the operational feel of the release control. Double is program-controlled attack and release that builds density without any pumping. This is similar to how the original Gates Sta-Level compressor operated. Triple combines program-controlled release and fast attack. Triple quickly caps transients and is the least transparent out of the three modes. The front panel VU meter lets you monitor all three compression modes with a three-position toggle switch. The Recovery Knobs lets you set the recovery time of the compressor once the signal slips below the threshold. Other Retro Sta-Level features include XLR transformer-balanced I/O, an IEC power connector and an internal component safety cover.
