★The "A4-1B Plugin Control Function (Perpetual License)" is bundled and included in card format. ■From reproduction to evolution. The A4-1B Tube-Optical Compressor is the first optical compressor to feature digital control and automation capabilities, bringing the renowned OptoTube design and sound to the modern era. Using carefully selected, top-quality components and featuring innovative optocell automatic calibration, it ensures 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 Scandinavian sound and employs a completely analog circuit. Constructed with high-quality components, it delivers precise and transparent compression. Furthermore, it offers the professionalism and innovation demanded by music production professionals, including remote control and automation from DAW plugins, and filtering that enables targeted compression. - All-analog design revives the sound of a genuine classic tube opto-compressor - Tight bass and high-fidelity audio sound produced by custom transformers and high-quality vacuum tubes - Remote control, automation, and preset recall functions via DAW plugin (VST3, AU, AAX) - Proprietary motorized potentiometer for instant remote response - User-configurable High-Pass, Band-Pass, and De-essing filter functions ■It is constructed with genuine, premium analog components, going beyond being just a compressor to achieve the true quality of timeless analog engineering. The combination of a meticulously designed signal path, high-quality vacuum tubes, and custom-made British transformers produces unparalleled musicality and rich bass, accurately reproducing the original compression characteristics. Even when applied to its maximum potential, it breathes new life into vocals, bass, keyboards, and percussion without losing their clarity. ■Classic sound, cutting-edge technology: Combining the warmth of analog with modern engineering, it delivers unparalleled sound quality and performance. Utilizing advanced technology, this power supply design ensures stability and reliability, and features an automatic voltage regulation function. Furthermore, DC ignition of the vacuum tubes minimizes noise and enhances the warmth of the tone. Digital control technology simplifies compression adjustment, allowing for faster and more precise operation. The automatic opto-cell calibration system ensures that the compression characteristics are perfectly matched in stereo, and its performance remains unchanged even after decades of use. ■Analog and Digital Fusion: We offer A4 DAW plugins that support VST3, AU, and AAX formats with remote control capabilities, enabling complete integration with your DAW environment. Our proprietary motor-driven knobs instantly reflect settings to the hardware, allowing you to maintain consistency between sessions by utilizing presets and easily perform A/B testing. Attack, Release, Gain, Threshold, and Ratio can be automated directly within the DAW plugin, just like with native tools. Additionally, the extended filter section includes Low-Pass, High-Pass, and Band-Pass filters, making it ideal for sidechain applications. Furthermore, in De-ess mode, you can use a Narrow Band-Pass Filter to pinpoint and remove unwanted components from vocals and instruments. ■Features: True analog sound: • 100% pure analog circuitry • High-quality components for superior sonic performance • Custom-designed UK-made transformers and premium vacuum tubes • Pre-sorted opto-cells to ensure optimal compression accuracy • Push-pull all-tube amplifier • Continuously variable attack/release time • Fixed, manual, and hybrid timing modes Automatic calibration system: • Guaranteed compression accuracy over time • Advanced power supply for extended vacuum tube life and reduced hum • Stable stereo link performance through calibration system • VU meters for monitoring input, compression, and output • Multiple reference levels for meters Analog automation: - Remote control via VST3, AAX, and AU plugins - Custom-designed motor-driven knobs allow for instant application of settings to the hardware - Comprehensive preset system and options for rapid A/B testing - Automation of Attack, Release, Gain, Threshold, and Ratio using DAW plugins - Extended filtering section with Low-Pass, High-Pass, and Band-Pass filters for sidechaining - De-essing mode using a Narrow Band-Pass filter ■Included items: A4-1B analog compressor unit, Power cable USB-C to USB-C cable • Quick Start Guide • A4-1B Plugin Perpetual License Leaflet *Please check the manufacturer's website for detailed product specifications. *Please check your operating environment and requirements before purchasing. *Product specifications, prices, and accessories are subject to change without notice.
