LA-2A Leveling Amplifier

LA-2A Leveling Amplifier

The LA-2A Leveling Amplifier is an audio compressor originally produced by Teletronix in the early 1960s. Three versions of the LA-2A were made until 1969. [http://www.uaudio.com/_works/pdf/manuals/LA-2A_manual.pdf] The LA-2A was inducted into the TECnology Hall of Fame in 2004. [http://www.mixfoundation.org/hof/04techof.html#13]

The LA-2A is a hand-wired, tube-based, compressor that uses a electro-luminescent panel together with a cadmium-sulfide light dependent resistor to provide gain reduction.

The LA-2A has simple controls: a Peak-Reduction knob controls the gain of the side-chain circuit, and therefore, the gain reduction; a Gain Control for make-up gain; and a Limit/Compress switch which alter the compression ratio. The VU meter, may also be switch to show gain reduction or output level.

The LA-2A has a sonic character make it sought after by many recording engineers.
