The 266xs puts pleasing compression and smooth gating within reach of everyone. The classic dbx® compression delivers everything from mellow “leveling,” to aggressive peak limiting. In addition, the 266xs’s AutoDynamic™ circuitry continuously adjusts attack and release settings in real time in order to optimally match program material. The advanced gating circuitry in the 266xs uses a program-dependent timing algorithm to produce ultra-smooth release characteristics—even with complex signals. Thanks to the dynamic range of the dbx® VCA, the 266xs can provide reliable gating for any circumstance. The 266xs also includes separate LED ladders measuring gain reduction, compression threshold, and gate threshold, making the 266xs intuitive and easy to use.
