The precise opto-cell detection system guarantees precise compression characteristics, matching the authentic behavior of the original. Crafted with premium analog components, the A4-1B is not just a compressor—it’s a testament to the timeless quality of true analog engineering.

Classic Sound, Modern Engineering.

The A4-1B combines analog warmth with modern engineering for unparalleled performance. Its efficient power supply ensures stability and reliability with automatic voltage adaptation, while DC heating for the tubes minimizes noise and enhances tonal warmth. Digital control technology streamlines compression adjustments, offering faster and more precise operation. These innovations not only improve the device's efficiency but also enhance the overall user experience, making the A4-1B a perfect blend of classic sound and modern precision for professional audio workflows.

Bringing Analog into the Digital Age.

The A4-1B also has access to the optional A4 software suite, allowing for remote control via VST3, AAX, or AU plugin, or standalone app, offering full integration into your DAW setup. Proprietary motorized knobs allow settings to be applied instantly to the hardware, while the preset system ensures easy recall for consistency across sessions and A/B testing. Attack, Release, Gain, Threshold, and Ratio can be automated directly in the DAW plugin, just like with any native tool. The extended filter section includes low pass, high pass, and band pass filters for sidechain applications, and the de-es mode with a narrow band pass filter helps clean up vocals and instruments with precision.

*The A4 software suite is available as an optional addon, as part of a monthly or annual membership plan. The A4-1B comes with 1 year of Antelope Membership for free, including the full suite of Synergy Core Native plugins, as well as all new releases and updates.
