\u0422he A4-1B Tube-Optical Compressor combines the warmth of classic tube compression with
\nthe precision and flexibility of modern technology. Faithfully recreating the iconic
\nScandinavian sound, the A4-1B boasts a fully analog circuit for the audio signal, built with
\nthe highest quality components to ensure precise and transparent compression. Its
\nadvanced features, including DAW integration for remote control and automation, and
\nfiltering for targeted compression, provide a seamless experience for audio professionals
\nseeking both authenticity and innovation.
\n\uf0b7 All-analog design preserving the true sound of classic opto-valve compression
\n\uf0b7 Custom transformers &amp; hi-end tubes for tight low-end and high-fidelity audio
\n\uf0b7 Remote control, with automation and preset recall
\n\uf0b7 Proprietary motorized potentiometers ensuring instant remote response
\n\uf0b7 User-configurable high-pass, band-pass and de-essing filters<\/p>\n

As Authentic as It Gets.
\nThe A4-1B captures the essence of legendary compression. A painstakingly accurate signal
\npath, premium tubes, and custom transformers combine for unparalleled authenticity and
\nlow-end richness. The precise opto-cell detection system guarantees precise compression
\ncharacteristics, matching the authentic behavior of the original. Crafted with premium
\nanalog components, the A4-1B is not just a compressor\u2014it\u2019s a testament to the timeless
\nquality of true analog engineering.<\/p>\n

Classic Sound, Modern Engineering.
\nThe A4-1B combines analog warmth with modern engineering for unparalleled
\nperformance. Its efficient power supply ensures stability and reliability with automatic
\nvoltage adaptation, while DC heating for the tubes minimizes noise and enhances tonal
\nwarmth. Digital control technology streamlines compression adjustments, offering faster
\nand more precise operation. These innovations not only improve the device&#39;s efficiency but
\nalso enhance the overall user experience, making the A4-1B a perfect blend of classic sound
\nand modern precision for professional audio workflows.
\nBringing Analog into the Digital Age.
\nThe A4-1B also has access to the optional A4 software suite, allowing for remote control via
\nVST3, AAX, or AU plugin, or standalone app, offering full integration into your DAW setup.
\nProprietary motorized knobs allow settings to be applied instantly to the hardware, while
\nthe preset system ensures easy recall for consistency across sessions and A\/B testing.
\nAttack, Release, Gain, Threshold, and Ratio can be automated directly in the DAW plugin,
\njust like with any native tool. The extended filter section includes low pass, high pass, and<\/p>\n

band pass filters for sidechain applications, and the de-es mode with a narrow band pass
\nfilter helps clean up vocals and instruments with precision.
\n*The A4 software suite is available as an optional addon, as part of a monthly or annual
\nmembership plan. The A4-1B comes with 1 year of Antelope Membership for free, including
\nthe full suite of Synergy Core Native plugins, as well as all new releases and updates.
