The LA2A becomes a component of tube equipment where the differences in 12AX7 brands may be heard. Additionally, the quantity of noise between tubes is easily audible. The LA-2A can maintain the appearance of musical characteristics while executing extreme-level management—a sound feature that several audio engineers seek out, especially for vocals and bass guitar usage. The LA-2A is a tube-based compressor that was hand-wired. To gain control, it employs an electroluminescent screen in conjunction with a cadmium-sulfide light-dependent resistance (dubbed the T4 cell by the LA-2A). The T4 features provide the LA-2A with its distinct personality by giving it a completely program-dependent structure.
