Vocal Channel in Fairlight
A current-interface guide to Fairlight's compact Vocal Channel plug-in: High Pass, three-band Equalizer and Compressor in one insert, with response graphs and gain-reduction monitoring.
1. Interface anatomy
Three familiar jobs inside one fast channel strip
High Pass
The current UI exposes a Frequency control from 20 to 300 Hz. Its job is to remove low-frequency content below the useful range when that content is actually unwanted — not to thin every voice by default.
Equalizer
Three tonal bands — Low, Mid and Hi — each expose a frequency target and gain. The UI also shows selectable filter-shape buttons for the bands, so use the shape that matches the tonal task instead of forcing every move into the same curve.
Compressor
The compact compressor exposes Threshold, Ratio, Reaction and makeup Gain plus a Gain Reduction meter. It is designed for fast channel control; the dedicated Compressor page remains the better place for a deeper dynamics workflow.
2. Live parameter map
Current ranges visible in Resolve 21
These ranges come from the live plug-in screenshot. The displayed example values are not presets and should not be copied blindly.
High Pass
Frequency: 20–300 Hz. The section has its own enable switch.
Low EQ
Low Freq: 35–330 Hz. Low Gain: −18 to +18 dB. Selectable filter-shape buttons are visible above the control pair.
Mid EQ
Mid Freq: 250 Hz–8.2 kHz. Mid Gain: −16 to +16 dB. The current UI offers alternate mid-band shapes.
Hi EQ
Hi Freq: 5–17 kHz. Hi Gain: −18 to +18 dB. Selectable shape buttons mirror the compact channel-strip approach.
Compressor · Threshold
Threshold: −40 to 0 dB. This determines the level region where compression begins to act.
Compressor · Ratio
Ratio: 1.1–7.0. Higher values increase the amount of level control above the threshold region.
Reaction
Continuous Fast ↔ Slow reaction control. Use it by listening to word attacks, consonants and overall movement rather than chasing one universal value.
Gain + Reduction
Makeup Gain: 0–20 dB. A dedicated Gain Reduction meter shows how deeply the compressor is acting.
3. Graphs and meters
The UI tells you what the channel is doing
The left graph visualizes the combined tonal response of the Vocal Channel EQ section. The right graph compares the linear input/output relationship with the active compression transfer curve, making threshold and ratio easier to understand visually.
The Gain Reduction meter is the fastest reality check: if the compressor is reducing continuously or much harder than intended, solve the level problem before assuming more compression is the answer.
EQ graph
Use it to see the combined direction of your tonal moves, but judge the result by ear in context.
Compression graph
The bend away from the straight reference line shows how level growth is being reduced above the compression region.
Gain Reduction
Watch how much the compressor is actually working instead of relying only on the Threshold and Ratio numbers.
Output
Final output metering helps you catch level changes after the combined channel processing.
4. Practical workflow
Use Vocal Channel when speed and a compact chain matter
Start with the source
Choose the correct mic/channel and balance obvious clip-level mismatches before the plug-in.
High-pass only what is unwanted
Move the filter until rumble or unusable low end is controlled without thinning the voice.
Shape tone with a few moves
Use Low, Mid and Hi bands for clear tonal goals instead of creating a complicated curve inside a compact strip.
Compress only as needed
Set Threshold/Ratio/Reaction while watching Gain Reduction, then compare bypass at similar loudness.
5. Vocal Channel vs separate processors
Compact does not mean universally better
Vocal Channel is excellent when one insert can solve basic filtering, tonal shaping and dynamic control. Use the dedicated Equalizer or Compressor when you need deeper control, and use Dialogue Processor or restoration tools when the real problem is rumble, pops, sibilance or noise rather than tone and dynamics.
Vocal Channel
Fast all-in-one: High Pass + 3-band EQ + compact compressor.
Equalizer
Choose the dedicated six-band Equalizer when frequency shaping needs more bands, Q control and a larger response workflow.
Compressor
Use the dedicated compressor guide for a fuller dynamics strategy and relationship with clip gain, Leveler, expander and limiter.
Dialogue Processor
Choose it when the source needs focused dialogue repair modules before or instead of general tone shaping.
Blackmagic introduced Vocal Channel as one of its built-in cross-platform Fairlight FX and current Fairlight documentation confirms the broader insert, EQ and dynamics architecture. The exact Resolve 21 Vocal Channel controls, ranges, graphs and layout described here come from the supplied live interface screenshot, avoiding assumptions from older UI versions.
