Universal Audio LA-2A

Classic Studio Levelling Amplifier

Order Code: LA2A
RRP: $8,699.00

A serious bit of kit for the studio. Not everyone gets to have a go at putting an LA-2A in the chain, but those who do never go back to doing without one.

Based on the original Teletronix® LA-2, the LA-2A has become a classic in its own right.

A unique tube-driven electro-optical attenuator system allows instantaneous gain reduction with no increase in harmonic distortion. If you want a serious vocal compresser, this is absolutel gold for your signal chain.
