HEDD Audio announces HEDD CTRL, a software platform designed to provide complete control and transparent calibration of its MK2 monitors and BASS subwoofers.
The MK2 series combines meticulous acoustic engineering and advanced digital signal processing to deliver sonic truth — a reliable monitoring foundation for engineers across projects and environments. CTRL builds on this concept, transforming the MK2 range into a fully integrated monitoring system.
Your monitoring. Your rules.
CTRL makes HEDD's slogan "Your monitoring, your rules" a practical reality. It unifies every MK2 function within an intuitive interface, enabling engineers to prepare, fine-tune, and control their entire monitoring system from the listening position. Every adjustment, from EQ and bass extension to shelving, desktop filters, and CoP (Closed or Ported) modes, can be made in real time with full visibility, without relying on automated processing. Profiles can be saved and recalled for different sessions, formats, or listening positions to ensure consistent results across all setups. CTRL provides direct, manual access to every parameter, returning knowledge and control to engineers and encouraging clarity and understanding instead of black-box automation.
Scalable Precision
In modern production, flexible system tuning is a necessity. CTRL can scale from a two-channel setup to an immersive environment with up to 250 speakers, giving engineers precise control over every element of their monitoring chain. Each speaker or group can be calibrated using a 10-band parametric equalizer (EQ) and per-speaker delay control to maintain accurate time alignment. System-wide phase linearization between satellites and subwoofers ensures coherent behavior across 2.1, surround, and immersive configurations. This transparent calibration approach gives professionals confidence that what they hear is accurate in every format and room.
Phase Fidelity as a Foundation of Truth
For HEDD, phase fidelity is not just a detail, but rather the foundation of sonic truth.Even without the Lineariser® engaged, the MK2 monitors deliver a neutral and reliable reference for critical listening. When the Lineariser® is activated — now switchable directly within CTRL — the already accurate performance is refined further, producing a perfectly aligned phase response and coherent direct sound before room reflections take over. CTRL also allows for the seamless switching between linear-phase mode for mixing and low-latency mode for tracking, thus maintaining consistent precision across workflows.
Built for the Way You Work
The CTRL is more than just an interface between engineers and monitors; it's an extension of the MK2 system, designed for modern studios that require flexibility and long-term reliability. Thanks to CoP technology, each speaker offers two distinct acoustic characters, providing the benefit of two monitor sets in one. Because CTRL is software-based, it can evolve over time, ensuring compatibility with new formats and workflows through future updates. Whether you're mixing in stereo or designing full immersive systems, CTRL preserves a consistent sonic identity across rooms, projects, and environments.
