OVERVIEW

Accurate recreation of a world-class Scandinavian compressor, combining smooth tube-optical warmth with precision controls.

The Warm Audio WA-1B Optical Compressor is an accurate recreation of a world-class Scandinavian compressor combining smooth tube-optical warmth with precision controls. Like the original favored by producers and engineers from Chris Lord-Alge to Rick Rubin, the WA-1B delivers that revered “forgiving” musical compression of tube-optical circuitry with speed and control more closely associated with modern dynamics processing. Hand-wired to authentically recreate the original true-to-spec circuit, the WA-1B combines custom large-core transformers from Lundahl Sweden, select tubes from JJ and Tung-Sol, and a premium high-precision optical element for ultra-fast and accurate operation without sacrificing authentic analog warmth.

To deliver extended dynamics processing, the WA-1B features all the classic controls of the original. The WA-1B supports a variable threshold giving maximum control to the user regarding how much compression is applied to any signal at various input levels. The WA-1B ratio is variable and has infinite controls between 2:1 and 10:1. From soft musical dynamic control all the way to hard-smashing compression.

The WA-1B is a 270v circuit with handwired through-hole circuitry, and 100% discrete analog signal path. The custom large-core transformers from Lundahl Sweden bring the full Scandinavian-style analog tone of the WA-1B circuit to life. Paired with select tubes from JJ and Tung-Sol, the high-precision optical element applies sweet analog warmth to audio signals with unrivaled accuracy.

Like all Warm Audio gear, the WA-1B is meticulously hand-tested and inspected by trained technicians with a passion for making music in Austin, Texas.
