The 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. Keyfeatures: ● Accurately recreating world-class Scandinavian compression combining smooth tube-optical warmth with precision controls ● True-to-spec 270 volt, 100% discrete analog signal path - handwired with through-hole components ● Transformer-balanced fully floating input and output - Custom-core large transformers from Lundahl in Sweden ● 12AX7 Tung-Sol & JJ 12AU7 tubes ● Frequency response @ -3 dB: 5 Hz to 25 kHz ● Self-Noise: < -75 dBU @ 30 dB gain ● CMRR: > 60 dB @ 10 kHz ● Ratio from 2:1 to 10:1 ● Variable Threshold: Off to -40 dBU ● Continuously variable attack and release times: fast-slow ● Output gain: Off to +30 dBU ● Input impedance: 600Ω ● Two bus connectors to connect multiple sidechains ● Meter (VU) input, output, or compression amount ● Linear, low-noise power supply with toroidal power transformer
