The Heritage Audio 2264E compressor limiter is a diode bridge based dynamics module, engineered to be used in vintage 80 Series consoles. It can also be installed in the Heritage Audio Frame 8 and Rack 2, where there is provision for linking up to 8 units in 2 different buses. It is fully Class A, including the same output stage found in the HA1073, which reacts in a much nicer way to compression than class A/B amplifiers. It is completely handmade and wired in the same fashion as the rest of the Heritage Audio 80 Series modules.
