The FC Pro Mixthesizer SUMPRESSOR is an analogue master compressor and summing unit that integrates four stereo inputs, transformer-based DI output, sidechain filtering, and precision metering to deliver final-stage dynamic control, tonal shaping, and signal consolidation for professional live and studio environments. The unit combines the character of classic analog compression with modern workflow enhancements, offering a streamlined yet powerful solution for final-stage signal management. It operates as both a mastering compressor and a compact performance hub, allowing engineers and performers to shape dynamics, control levels, and manage multiple sources from a single device placed directly before the sound system. Its architecture supports intuitive operation while maintaining the sonic integrity expected from high-end analog circuitry. Dynamic Control and Compression Architecture The SUMPRESSOR centres around a responsive compression engine controlled via input, Action, and output parameters, each supported by a detailed 10-LED metering system. This layout ensures immediate visual feedback and precise gain staging at all times. The Action control governs the compression behaviour, enabling users to quickly dial in anything from subtle glue to more assertive dynamic shaping. The inclusion of preset modes alongside a fully adjustable user mode allows both rapid deployment and detailed customisation of attack, ratio, and release characteristics. Integrated Analog Summing The unit features four stereo inputs, including three accessible from the front panel and an additional rear XLR input, all summed through the compressor stage. This configuration allows multiple sources to merge into a cohesive stereo signal while benefiting from unified dynamic processing. The summing stage enhances workflow efficiency in both live and studio contexts, removing the need for additional routing equipment while preserving clarity and balance. Sidechain Filtering and Low-End Management A selectable high-pass sidechain filter provides targeted control over how low frequencies interact with the compression circuit. With frequency options at 200, 120, 90, and 60 Hz, the SUMPRESSOR prevents excessive low-end energy from triggering unwanted compression, ensuring a tighter and more controlled mix without sacrificing bass presence. Output Versatility and Signal Routing The main output stage incorporates a custom transformer-based DI, switchable as required, delivering a robust and harmonically rich balanced signal suitable for direct connection to professional sound systems. Alongside this, a dedicated Utility Output on TRS with independent level control offers additional routing flexibility, making it suitable for monitoring, parallel processing, or secondary signal distribution. Mixer Mode Functionality When compression is bypassed, the SUMPRESSOR operates as a transparent stereo summing mixer with balanced output. This mode allows the unit to function purely as a signal hub, maintaining flexibility in scenarios where dynamic processing is not required while still benefiting from its high-quality analog summing path. Performance-Focused Design The design prioritises immediacy and reliability, ensuring that users can make rapid adjustments in high-pressure environments such as live performances or recording sessions. The clear metering, logical control layout, and robust analog signal path support confident operation while maintaining consistent sonic results. Why Choose SUMPRESSOR Delivers confident control at the final stage, ensuring mixes translate cleanly to any sound system Simplifies complex setups by combining compression, summing, DI, and mixing in one unit Enables fast decision-making with clear metering and intuitive controls Adapts easily to both live and studio workflows without additional equipment Preserves sonic integrity while adding cohesion, punch, and clarity to the overall mix
