■From reproduction to evolution.
The A4-1B Tube-Optical Compressor is the first optical compressor with digital control and automation capabilities, bringing the legendary optotube design and sound to a modern day world.
Crafted using only the highest quality components, it features an innovative, automatic optocell calibration to ensure consistent compression characteristics for decades to come.

The A4-1B Tube-Optical Compressor combines the warmth of classic tube compression with the precision and flexibility of modern technology.
It faithfully reproduces the iconic Nordic sound and uses a fully analog circuit.
Constructed with high-quality components, it delivers precise and transparent compression.
It also offers the authenticity and innovation that professional music producers demand, including remote control and automation from DAW plug-ins, and filtering that enables targeted compression.

All-analog design that recreates the sound of authentic, classic tube and opto-compressors. Custom transformers and high-quality vacuum tubes produce tight low frequencies and high-fidelity audio. Remote control, automation, and preset recall via DAW plug-ins (VST3, AU, AAX). Proprietary motorized potentiometer for instant remote response. User-configurable High-Pass, Band-Pass, and De-essing filters.

■Made up of the most authentic premium analog components, it is more than just a compressor; it achieves the timeless quality of true analog engineering.
A meticulously engineered signal path, high-quality tubes, and custom British-made transformers combine to produce unparalleled musicality, rich low end, and accurately reproduce the compression characteristics of the original.
Pushed to its limits, it breathes new life into vocals, bass, keyboards and percussion without losing clarity.

■Classic sound, cutting-edge technology Combining the warmth of analog with modern engineering, it delivers unparalleled sound quality and performance.
The highly efficient power supply design uses advanced technology to ensure stability and reliability, and is equipped with an automatic voltage regulation function.
Additionally, DC firing of the vacuum tubes minimizes noise and enhances the warmth of the tone.
Digital control technology simplifies compression adjustment for faster and more precise operation.
The automatic opto-cell calibration system ensures perfectly matched compression characteristics in stereo, ensuring performance that will last for decades.

■Analog and Digital come together to provide the A4 DAW plug-in, which supports VST3, AU, and AAX formats and can be remotely controlled, enabling full integration with DAW environments.
The proprietary motorized knobs ensure settings are instantly reflected in the hardware, and presets ensure consistency between sessions and make A/B testing easy.
Attack, Release, Gain, Threshold and Ratio can be automated directly within the DAW plug-in, just like native tools.
The extended filter section also includes Low-Pass, High-Pass and Band-Pass filters, making it ideal for sidechain applications.
Additionally, De-ess mode uses a Narrow Band-Pass Filter to pinpoint and remove unwanted components from vocals and instruments.
