03In depth

Sound Shaping With Nine Controls

The EQ section uses three controls. AIR adjusts the high frequencies, FOCUS adjusts the clarity of the mids, and BODY adjusts the low frequencies. BASS PUNCH controls low-end boost and tightness together, while ANALOG adds harmonic enhancement for color and dimension.

TRANSIENTS can enhance or soften attacks, which affects how much impact a mix has. Together, these controls cover the main tonal and dynamic adjustments needed when finishing a track.

Compression and Loudness Through Two Knobs

The PUSH knob is a single control for compression. It is designed to make compression adjustments simple while staying precise and natural. VOLUME is the second main control and is intended to raise perceived loudness on the output.

Because the two main controls are placed up front, One suits producers who want a fast, streamlined path to a finished master without building a full processing chain by hand.
