Antelope A4-1B Opto Valve Compressor

Antelope A4-1B:Opto Valve Compressor Overview

The A4-1B Tube-Optical Compressor blends the warmth of traditional tube compression with the accuracy and versatility of contemporary technology. The A4-1B faithfully recreates the unique Scandinavian sound, with a completely analog audio signal circuit designed with high-quality components to provide accurate and transparent compression. Its sophisticated features, such as DAW connection for remote control and automation and filtering for focused compression, give audio pros a seamless experience that balances authenticity with innovation.

1.  The all-analog architecture preserves the authentic sound of vintage opto-valve compression.
2.  Custom transformers and high-end tubes provide precise low-end and high-fidelity sounds.
3.  Remote control with automation and preset recall.
4.  Proprietary motorized potentiometers provide instant remote response.
5.  Customizable high-pass, band-pass, and de-using filters.

As authentic as it gets.

The A4-1B embodies the spirit of legendary compression. A meticulously precise signal route, quality tubes, and bespoke transformers combine to provide unrivaled authenticity and low-end richness. The accurate opto-cell detection technique ensures that compression features reflect the real behavior of the original. The A4-1B, built with superior analog components, is more than simply a compressor; it exemplifies the eternal quality of pure analog engineering.

Classic sound, modern engineering.

The A4-1B mixes analog warmth with cutting-edge engineering to deliver exceptional performance. Its efficient power supply assures stability and dependability through automated voltage adaption, while DC heating for the tubes reduces noise and increases tone warmth. Digital control technology simplifies compression changes, resulting in quicker and more precise operation. These enhancements not only increase the device’s efficiency but also improve the whole user experience, giving the A4-1B the ideal combination of traditional sound and current accuracy for professional audio operations.

Bringing analog to the digital age.

The A4-1B also has access to the optional A4 software package, which allows for remote control via VST3, AAX, or AU plugins, as well as a standalone app, enabling complete integration into your DAW system. Proprietary motorized knobs enable adjustments to be applied to the hardware instantaneously, while the preset system assures simple recall for consistency across sessions and A/B testing. Attack, Release, Gain, Threshold, and Ratio may all be automated from within the DAW plugin, just like any native tool. The expanded filter section comprises low pass, high pass, and band pass filters for sidechain applications, while the de-es mode, which includes a narrow band pass filter, cleans voices and instruments precisely.

The A4 software package is available as an optional add-on for monthly or annual membership plans. The A4-1B includes a free one-year Antelope Membership, which includes the whole suite of Synergy Core Native plugins, as well as all new releases and upgrades.
