A little weight.
A little air.

Fixed bands for broad tonal balance, with a separate shelf for the top end.

Sub and 40 Hz

Shape the foundation with dedicated Sub and 40 Hz controls. Start with small moves and check how the low end sits against the kick and bass.

160 Hz and 650 Hz

Add body or reduce low-mid buildup. These broad bands help place vocals and instruments without searching through a continuous frequency range.

2.5 kHz

Adjust the upper-mid shelf to bring a part forward or soften its presence. Balance this band against Air when adding brightness.

Air frequency

Choose Off, 2.5, 5, 10, 15, 20 or 40 kHz. The higher positions create a broader lift toward the audible top end; they do not require an ultrasonic audio source.

Air gain

Raise Air from 0 to 10 to blend in the selected shelf. Start gently on a vocal, then check consonants and cymbals in the full mix.

Output and comparison

The parallel bands also affect overall level. Trim Output by up to 12 dB in either direction and use In to compare at a similar listening level.

Start with the track

Start with the five tone bands at their centre positions and Air at 0. Shape the body and presence first, then select an Air frequency and raise Air gradually. The tone dials use −5 to +5 panel positions rather than direct dB values. The bands interact in a parallel network, so match the output level when comparing.
