CL-4 PC Tool’s 10-band EQ lets you craft studio-grade soundscapes with parametric filters and presets. Perfect for audiophiles. Sculpt frequencies for any genre or space.

- 10 Parametric Filters: Adjust frequency (20Hz-24kHz), gain (-12 to +12dB), and Q factor (0.707-10) for precise cuts/boosts.
- Filter Types: Choose Peaking (precision boosts), High Shelf (adjust treble), or Low Pass (cut subsonic rumble).
- Pre Gain Control: Fine-tune overall output (-10 to +3dB) to prevent clipping, especially when stacking EQ boosts.
- Live Venues: Cut 200-500Hz in the main stage zone to reduce mud, while boosting 10kHz in the balcony for clarity.
- Home Studios: Use Low Shelf at 50Hz (+3dB) for electronic music, and High Shelf at 8kHz (-2dB) to soften harsh treble in podcasts.
- Save/Load Presets: Store "Club Mode," "Vocal Boost," or "Acoustic Guitar" settings for instant recall.
- Sync Across Zones: Copy EQ settings from Zone 1 to Zones 2-4 with the "Sync" button, ideal for maintaining consistency in multi-room setups.
