{"product_id":"warm-audio-wa-1b-all-tube-optical-compressor","title":"Warm Audio WA-1B All-Tube Optical Compressor","description":"\u003cp\u003eThe Warm Audio WA-1B is a precision recreation of the iconic Scandinavian tube-optical compressor, designed to deliver the famously smooth and “forgiving” analog compression that has shaped countless professional recordings. Known for its musical character and natural dynamic control, the WA-1B blends vintage optical warmth with modern precision, making it ideal for highly dynamic sources such as vocals, bass, drums, and instruments that require both transparency and character.\u003c\/p\u003e\u003cvideo controls width=\"100%\"\u003e\n  \u003csource src=\"https:\/\/cdn.shopify.com\/videos\/c\/o\/v\/7b68b308003d4122919391fae8c9c8d8.mp4\"\u003e\u003c\/video\u003e\n\n\u003cp\u003eBuilt for complete control over dynamics, the WA-1B features a fully variable threshold and an infinitely adjustable ratio from 2:1 to 10:1, allowing everything from subtle leveling to aggressive compression. Its advanced attack and release system offers fixed, manual, and combined modes, enabling users to shape both natural optical response and more complex time-constant curves. A versatile VU meter provides input, gain reduction, and output monitoring, while a true hard-bypass switch ensures complete signal integrity when disengaged.\u003c\/p\u003e\n\u003cp\u003eAt its core, the WA-1B is built around a 270V fully discrete, handwired analog circuit using premium components including Lundahl large-core Swedish transformers, carefully selected JJ and Tung-Sol tubes, and a high-precision optical element. This combination delivers deep analog warmth, smooth response, and exceptional accuracy. Hand-tested in Austin, Texas, the WA-1B brings world-class tube-optical compression into a modern, reliable studio tool for professional engineers and producers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign: \u003c\/strong\u003eFully Discrete, Handwired Analog Signal Path\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperating Voltage: \u003c\/strong\u003e270V True-to-Spec Analog Circuit\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChannels: \u003c\/strong\u003eStereo \/ Dual-Channel\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompression Ratio: \u003c\/strong\u003e2:1 to 10:1\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreshold Range: \u003c\/strong\u003eOff to -40 dBU\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAttack Time: \u003c\/strong\u003eFixed 1 ms \/ Manual 0.5–300 ms\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRelease Time: \u003c\/strong\u003eFixed 50 ms \/ Manual 0.05–10 s\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAttack\/Release Mode: \u003c\/strong\u003eFixed, Manual, Fixed\/Manual Blend\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Gain: \u003c\/strong\u003eOff to +30 dBU\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance: \u003c\/strong\u003e600Ω\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTransformers: \u003c\/strong\u003eCustom-Core Lundahl (Sweden), Fully Transformer-Balanced I\/O\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSignal Path: \u003c\/strong\u003e100% Discrete, Through-Hole Handwired\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTubes: \u003c\/strong\u003e12AX7 Tung-Sol \u0026amp; JJ 12AU7\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response: \u003c\/strong\u003e5 Hz – 25 kHz (-3 dB)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSelf-Noise: \u003c\/strong\u003e\u0026lt; -75 dBU @ 30 dB Gain\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCMRR: \u003c\/strong\u003e\u0026gt; 60 dB @ 10 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMetering: \u003c\/strong\u003eVU Input \/ Output \/ Gain Reduction\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSidechain: \u003c\/strong\u003eDual Bus Connectors for Linking Multiple Units\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Supply: \u003c\/strong\u003eLinear Low-Noise with Toroidal Transformer\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Weight: \u003c\/strong\u003e9.5 lbs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Dimensions (L x W x H): \u003c\/strong\u003e19 x 9 x 3.5 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Weight: \u003c\/strong\u003e11.5 lbs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Dimensions (L x W x H): \u003c\/strong\u003e23 x 12.5 x 5.5 in\u003c\/p\u003e","brand":"Warm Audio","offers":[{"title":"Default Title","offer_id":47366975815933,"sku":"H-WARM-1B","price":1299.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/2308\/3005\/files\/2106635.jpg?v=1775841993","url":"https:\/\/hollywooddj.com\/products\/warm-audio-wa-1b-all-tube-optical-compressor","provider":"Hollywood DJ","version":"1.0","type":"link"}
