In the EQP-WA, Warm Audio has, in essence, re-created one of the most renowned tube Equalizers in studio history—the "Pultec EQP-1A." The goal was to bring to market an affordable equalizer of this magnitude for the first time, with no compromise in the quality and design parameters that make this type of equalizer so desirable. Not only does its look and feel match the classic Pultec, but its sonic quality has also been carefully considered and reproduced with the implementation of top-end components like CineMag USA transformers and premium-quality tubes. This fully-discrete Tube EQ can pull out euphoric sonics from any track and bring a luster and brilliance to mixes that’s extremely difficult to achieve inside-the-box.FeaturesTube Equalizer based on the classic “Pultec” EQP-1ACineMag USA input and output transformersPremium high voltage 12AX7 and 12AU7 tubesCineMag USA inductor EQ sectionBypassable EQ section - although signal still passes through tubes and transformers for warming effectNo insertion loss - loss restored by tube amplifierXLR and TRS transformer balanced inputsXLR and TRS transformer balanced outputsBoost and Cut controls can be used simultaneously for phase effect(5) added frequency points for greater flexibilitySwitchable 115/230 Volt IEC power inletSpecificationsFrequency Response: 20 Hz - 50 kHz, +/- 1 dBSelf Noise:< -75 dBInput Impedance: 600 ΩOutput Impedance: Capable of driving a 600 Ω loadPower: Selectable 115 V 60 Hz/230 V 50 Hz via standard grounded 3 conductor IEC cableFuse Compliment: 1 amp, 250-voltInput: Transformer balanced, pin 2/tip=positive, pin 3/ring=negative, pin 1/sleeve=groundOutput: Transformer balanced, pin 2/tip=positive; pin 3/ring=negative, pin 1/sleeve=groundLow frequency boost: 20, 30, 60, 100, 200, 400, 800 Hz - 12 dbLow frequency cut: 20, 30, 60, 100, 200, 400, 800 Hz - 18 dbHigh frequency boost: 3, 4, 5, 8, 10, 12, 16 kHz - 18 dbHigh frequency cut: 3, 4, 5, 10, 20 kHz - 14 dbDimensions: 19" x 3.5" x 6" - 2U rack-mountable Warm Audio EQP-WA Classic Vintage - Style Tube EQ.
