Opto 6 Optical Compressor: A Celebration of Legacy and Innovation

To honor 20 remarkable years, Drip proudly reintroduces one of its most cherished designs: the Opto 6 optical compressor. This masterfully crafted single-channel compressor is a modern homage to the revered 1968 LA-2A compressor, renowned for its warm, lush sound and unparalleled performance in recording studios worldwide.

The Opto 6 is a meticulous reproduction of the classic audio and gain reduction circuit, powered by a thoughtfully selected tube complement. With one 12AX7 and one 12BH7A serving as the signal amplifier, alongside another 12AX7 and 6AQ5A dedicated to the reduction circuit, this design ensures that your audio retains its integrity while delivering that sought-after tube warmth. For those who wish to elevate their experience even further, the option to integrate a 6X4 rectifier tube offers an elegant alternative to conventional 1N4007 diodes.

What distinguishes the Opto 6 is not just its heritage but its innovative features. The incorporation of dual T4B optical attenuators presents an exceptional versatility through selectable release speeds—fast and slow—allowing for precise control of your sound dynamics. This is craftsmanship that resonates with both nostalgia and modernity.

Designed with a spacious 16x7-inch PCB, this exceptional unit guarantees expansive track spacing and isolation, translating to an extraordinarily quiet operation. The 2024 updates enhance its functionality; optional SMA connections replace traditional RCA cables, and provisions for external power supplies can now be integrated effortlessly, providing additional filtering and DC heater support through the Drip universal PSU board.

Further attention to detail is evident in the enriched capacitor footprint options, accommodating higher-end components. The PCB is designed for substantial ATOM capacitors, while remaining compatible with contemporary axial 500V capacitors as ATOM capacitors reach the end of their lifecycle. Additionally, the output capacitor footprint is optimized for premium capacitors like the Mundorf Supreme series, ensuring every note resonates with clarity and richness.

The Opto 6 stands as a testament to Drip’s commitment to quality and innovation, celebrated and revered by a global community of users. Step into a world where classic artistry meets modern technology and experience the magic of the Opto 6 optical compressor—an essential instrument for any discerning audio engineer. Embrace the beauty of sound with Drip, and let this extraordinary design elevate your recordings to new heights.
