HEDD CTRL is a dedicated software that unifies the MK2 and BASS series of monitors and subwoofers into a transparent, reliable, and fully controllable monitoring ecosystem. It moves beyond back-panel adjustments, limited hardware controllers, and unreliable “black-box automation” to allow you to explore what your monitors can achieve in much more detail.

Experience complete system management from the monitoring position. Precision and flexibility scale seamlessly from simple stereo setups to immersive environments of up to 250 speakers.

CTRL is free for all MK2 users and available for both macOS and Windows.

Take Full Control of Your Sound

CTRL promotes clarity over automated processing and returns knowledge and decision-making to you.

Interact directly with EQ, delay, phase, and CoP (Closed or Ported) controls to fine-tune every element of your system in real time from the listening position.

  • Transparent manual calibration: Adapt each monitor precisely to your room with a 10-band parametric EQ available per speaker and per group.
  • Two monitor sets in one: Switch between Closed or Ported modes for two distinct acoustic characters within a single device.
  • Workflow presets: Prepare, store, and instantly recall complete profiles for different sessions, formats, or listening positions, making speaker management a natural part of your creative process.
  • Scalable control: Manage up to 250 speakers and create stereo, Sub/Sat (2.1), or immersive groups all within one place.

Absolute Precision and Trust with the HEDD Lineariser®

At HEDD Audio, phase fidelity is the foundation of sonic truth. Thanks to the Lineariser, engineers using MK2 monitors can achieve perfectly aligned phase response and make mix decisions with absolute confidence.

Until now, Lineariser functionality was only accessible via back panel controls. CTRL changes all this and makes it much easier for you to see and control what the Lineariser is doing and where, whether on individual monitors or groups.

  • Perfect phase alignment: When activated, the Lineariser refines the performance of MK2 monitors, providing a more coherent direct sound and perfectly aligned phase response.
  • Consistent time alignment: CTRL manages system-wide phase linearisation between satellites and subwoofers, ensuring consistent timing across the entire setup.
  • Workflow flexibility: Easily switch between linear-phase mode for critical listening and low-latency mode for recording.
