GLM4

GLM4 (Genelec Loudspeaker Manager 4) by Genelec Oy is a calibration and control software suite for Genelec Smart Active Monitors and subwoofers. Used together with the Genelec GLM kit and its calibrated measurement microphone, GLM4 measures your room and automatically optimizes your monitoring system for accurate, repeatable results.

Key capabilities:

• Automated in-room calibration: Runs measurements and applies precise adjustments for level, delay, frequency response, and subwoofer crossover to improve translation and imaging.
• Smart Active Monitoring control: Configures and manages compatible Genelec SAM monitors and subwoofers via the GLM network adapter and control cables.
• Stereo to immersive: Builds and manages systems from simple stereo to complex multichannel and immersive layouts.
• Groups, scenes, and presets: Creates multiple listening locations and profiles, with instant recall for different rooms, clients, or workflows.
• Volume and monitoring tools: Offers software-based system volume, mute/solo, bass management control, and safe operating levels.
• Store settings to speakers: Writes calibration data into each monitor and subwoofer so the system can run without a computer.
• Room insights: Provides detailed measurement visualizations and access to optional GRADE acoustic reporting to help interpret room behavior and guide improvements.
• Cross-platform: Available for macOS and Windows.

GLM4 streamlines setup, alignment, and daily control, helping you get the most accurate performance from Genelec SAM systems in music, post, broadcast, and installation environments.
