Acme Audio Opticom XLA-500

The Acme Audio Opticom XLA-500 is a dual slot single channel valve limiter for the popular 500 series format based on the Opticom XLA-3 MkII 
The Acme Audio Opticom XLA-500 has been scaled down to accommodate tube in its makeup gain circuit to retain the essential character of its bigger sibling. At its core it retains the triple opto-electronic circuit of its predecessor augmented by cinemag input and output transformers providing the same functionality as the original with a more focused and fat sound.
Inspired by the LA-2A the Opticom XLA-500 adds three speeds which recall other similar compressors with the the slow setting hinting towards a popular broadcast limiter designed to hold a mix together. The normal speed closely resembles the behaviour of the original LA-2A while in fast mode and the Opticom will behave similarly to the All-Button mode of the 1176 for a truly crunchy sound.
