NCL Phase EQ — Tips, Tricks, and PresetsNCL Phase EQ is a surgical, phase-aware equalizer designed for mixing and mastering engineers who need transparency and precision. It combines linear-phase and minimum-phase processing with flexible filter types, useful visual feedback, and workflow-friendly features that help you sculpt tone without introducing unwanted phase artifacts. This article collects practical tips, creative tricks, and ready-to-use preset ideas to get the most from NCL Phase EQ whether you’re cleaning up tracks, shaping tone, or adding character.
1. Understand the core modes: Linear vs Minimum phase
- Linear-phase mode preserves phase relationships across frequencies, preventing pre-ringing or phase shifts that can smear transient clarity. Use it when transparency is paramount — mastering, buses with many layered sources, or when aligning perfectly with other tracks.
- Minimum-phase mode introduces traditional phase shifts but often sounds more natural and slightly punchier. Use it on individual instruments (drums, bass, vocals) where character and transient weight are desirable.
Tip: Switch modes mid-session to compare; subtle differences can change focus and perceived depth.
2. Use gentle Q values for broad tonal shaping
Broad boosts/cuts with low-to-moderate Q (wider filters) create musical adjustments without ringing or unnatural resonances. For overall tonal balance:
- Low shelf (40–120 Hz) with gentle cut to control boom.
- High shelf (8–16 kHz) with gentle boost to add air.
- Wide mid cuts around 200–600 Hz to reduce boxiness.
Practical numbers: try Q ≈ 0.7–1.4 for broad moves; keep gain changes ±1–3 dB unless surgical intervention is needed.
3. Surgical cuts with narrow Q and spectrum scanning
For resonances, use narrow Q values and sweep to find offending frequencies:
- Set a narrow band (Q 6–12), boost a few dB, sweep slowly to locate the worst spot, then cut by 3–8 dB and return the band to neutral gain.
- Solo the band if NCL Phase EQ allows band soloing, or use spectrum analyzer/FFT to visually confirm.
Tip: After cutting, reduce Q slightly to avoid creating a hole; very narrow cuts risk sounding unnatural on polyphonic sources.
4. Preserve transients: high-pass thoughtfully
Apply high-pass filtering to remove subsonic rumble, but set the slope and cutoff carefully:
- Vocals: 60–120 Hz (gentle slope) to remove mic proximity noise without thinning.
- Guitars/pianos: 80–120 Hz depending on instrument.
- Mix bus: 25–40 Hz to keep low-end weight intact.
Use linear-phase HPF for mastering; minimum-phase for single tracks when punch matters.
5. Phase alignment and stereo coherency
NCL Phase EQ’s phase-aware design helps retain stereo image. When adjusting left/right channels or mid/side:
- Use identical EQ settings on L and R when preserving stereo balance is critical.
- For mid/side processing: apply wider boosts/cuts in the side channel to enhance width or reduce harshness without affecting center elements (vocals, kick, bass).
If you need to correct phase between close-mic’d sources, linear-phase mode minimizes smear; consider tiny timing adjustments in addition to EQ.
6. Use dynamic EQ features (if available)
If NCL Phase EQ includes dynamic or band-dependent dynamics:
- Use dynamic cuts to tame resonances only when they become problematic (e.g., sibilance or booming notes).
- Set attack/release so processing is transparent — fast enough to catch transients but not so fast that it becomes choppy.
Dynamic shelving can subtly control buildup in the mix bus without constant overtreatment.
7. Creative tricks for mixing
- Parallel processing: duplicate a track, apply stronger EQ on the duplicate (e.g., aggressive low-mid cut and high-shelf boost), then blend to taste for clarity + presence.
- Mid/Side air boost: gently boost highs in the side channel to add perceived openness without making the center harsh.
- “Frequency slotting”: carve small cuts in supporting instruments around the lead instrument’s key frequencies so the lead sits forward.
8. Mastering chain placement and gain staging
- Use NCL Phase EQ early in the master bus chain for corrective work (removing subsonics, taming resonance), and again later for tonal shaping if needed.
- Keep gain changes modest on the master bus (±0.5–1.5 dB typical). Large boosts often require downstream limiting/level compensation.
- Check gain staging: match input/output loudness when comparing settings to avoid bias from perceived loudness differences.
9. Monitoring and verification
- Always A/B with bypass and level-matched comparisons. Perceived improvements can come from loudness changes rather than better tone.
- Check in mono and multiple speaker setups (headphones, monitors, small speakers) to ensure your EQ choices translate.
- Use a spectrum analyzer and phase correlation meter to verify you haven’t introduced harmful phase cancellation or excessive frequency holes.
10. Presets: starting points to adapt
Below are practical preset concepts. Treat them as templates — adjust frequencies, Q, and gain per track and source.
-
Vocal Clean-Up (minimum-phase)
- HPF: 80–120 Hz, gentle slope
- Low-mid cut: 200–350 Hz, Q 1.5, −2 to −4 dB
- Presence boost: 3–6 kHz, Q 1, +1.5 to +3 dB
- Air shelf: 10–14 kHz, gentle +1 to +2 dB
-

- Snap boost: 3–6 kHz, Q 1.2, +1–2 dB
-
Mix Bus Gentle Sculpt (linear-phase)
- HPF: 25–30 Hz
- Low shelf: 40–80 Hz, Q 0.7, +0.5–1 dB
- Low-mid cut: 250–500 Hz, Q 0.8–1.2, −1 to −2 dB

-
Bass Focus (minimum-phase)
- HPF: 30–40 Hz (or none for sub-heavy material)
- Low boost: 40–80 Hz, Q 0.9, +1–3 dB
- Low-mid scoop: 200–400 Hz, Q 1–1.5, −2 to −4 dB
- Presence: 700–1.2 kHz slight +1 dB for articulation
11. Troubleshooting common issues
- Harshness after boosting highs: try switching to linear-phase for a smoother top end or use a gentler Q and smaller gain.
- Loss of punch after linear-phase processing: consider minimum-phase on rhythmic instruments or add transient shaping.
- Phase correlation dips after mid/side boosts: reduce side boost amount or widen Q to avoid cancellation in mono.
12. Final workflow checklist
- Choose phase mode appropriate to the task.
- High-pass to remove unnecessary subs.
- Use broad moves for tone, narrow for resonance removal.
- Level-match when A/Bing.
- Check mono compatibility and phase correlation.
- Save custom presets for repeatable results.
NCL Phase EQ is most powerful when used with intent: pick the right phase mode, make measurable adjustments, and verify across systems. With the tips, tricks, and presets above you should be able to move quickly from corrective work to subtle coloring while keeping mixes coherent and professional.
