With only Gain and Peak Reduction knobs, the Opto-2A is extremely easy to operate. With a twist of its switch, the compressor becomes a limiter. The key to its unique character is the T4 optical attenuator, a technology derived from optical sensors originally developed for the US military.
The Opto-2A’s sonic signature is its two-stage release, which greatly contributes to its smooth and musical compression, or a warm analogue drive when pushed harder. Despite its simple controls, the Opto-2A is endlessly versatile, but as it is designed for broadcast, it especially shines when used on vocals thanks to its incredibly musical response to the human voice. Put this compressor on a singer’s monitor chain or a voice-over artist’s chain, and you will hear its immediate impact on their performance.
Capable of handling and controlling a wide range of dynamics, the Opto-2A is also an excellent choice for compressing or limiting bass lines.
