Front End Audio has a fantastic deal on this factory direct B-Stock compressor! This WA-1B arrived to us directly from Warm Audio quality control where they deemed it as "B-Stock" for whatever reason. They have fully inspected this compressor and you will be hard pressed to find a flaw! However, in the nature of being B-Stock, do expect a minor cosmetic issue but rest assured that it will have absolutely no impact on the functionality or performance of this compressor. Otherwise, this compressor is brand new and carries a full manufacturers warranty. This is your opportunity to grab a deal on a "just like new" WA-1B from Warm Audio!

The Warm Audio WA-1B Optical Compressor accurately recreates world-class Scandinavian compression combining smooth tube-optical warmth with precision controls. The Warm Audio WA-1B accurately recreates world-class Scandinavian compression, combining smooth tube-optical warmth with precision controls. Like its original inspiration, 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 sound of a renowned 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.

True-To-Original Controls
To deliver extended dynamics processing, the WA-1B features all of the classic controls of its modern-classic inspiration.

  • Threshold: 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.
  • Ratio: 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!
  • Attack & Release: The Attack/Release controls on the WA-1B are unique in that the attack/release operations can be switched from a fixed setting, manual (variable) setting, or a combined setting. In the “fixed” mode, the WA-1B delivers the natural attack & release time of the optical element. The combined setting in particular creates the opportunity for a more nuanced release-time curve. This dueling time-constant circuit operation is a special feature of the WA-1B and its original inspiration.  
  • Meter Switch: The WA-1B meter switch has three settings: input, compression, and output levels. Set to “input”, the VU meter is reading the level at the input connector. Set to “compression”, the VU meter is reading gain reduction. The steady-state is "0", and the amount of compression is shown as the needle moving right-to-left away from 0dB. Set to “output”, the VU meter is reading the level at the output connector.
  • On/Bypass: The on/bypass switch on the WA-1B activates or bypasses the compressor. This is a hard bypass, meaning no signal passes through the circuitry in bypass mode.

Premium Components
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.

Hand-Tested In Austin, TX
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, TX USA.
