Warm Audio's WA73-EQ is a top-quality mic preamp/EQ that's part of their WA73 lineup.The Venerable 1073If there is a single preamp-eq that professional engineers would all agree has defined the sound of pop/rock records over the last 50+ years, the venerable 1073 most definitely be it. Massively used in recording and live applications for decades, even today it's still considered to be the best of the best of preamp-EQs. Providing single- and dual-channel re-creations of this classic British preamp (with & without EQ) the members of the “WA73 Family” each pay careful and humble homage to the original circuit.It was imperative, when Warm Audio decided to develop and release the WA73-EQ, that it pay respectful homage to the legendary British console history, both in design as well as performance. The tone and sweet sound characteristics that the vintage models provide is so unique and familiar that the only desire was to release truly sonically-accurate replicas. Those years of R&D, careful reverse-engineering, and countless hours of auditioning have all brought about the WA73-EQ.Know as a “Desert Island” boutique preamp-EQ, the WA73-EQ can also be safely classified as a studio and live sound work-horse. The classic 1073 was known for being a flexible tool that could work with all kinds of microphones: Condenser to Dynamic to Ribbon. The WA73-EQ now equally shines when working with all kinds of mics and source types, including: vocals, acoustic/electric guitars, bass, drums, percussion, orchestras, keyboards, and even as a tool for tone shaping to run partial or even complete mixes through. Its 80dB of gain and fully-discrete Carnhill Transformer-balanced signal path all ensure that there's no recording, mixing, or engineering task that the WA73-EQ can’t handle.Hand-Wired, Hand-AssembledJust like the classic 1073, the WA73-EQ is hand-wired. Those in the know assert that part of the 1073's classic tone can be attributed to its hand-wired assembly. Likewise, the WA73-EQ is classically hand-wired and hand-built – including the PCB components – all populated by hand.Warm Audio WA73-EQ Features:Single Channel, Class A, 1073-style British Microphone Preamp with inductor-based 3 band EQUK-made Carnhill TransformersUK-made Blore Edwards EQ dual-concentric switch potentiometers4-position inductor-based hipass filterHand-Wired, hand-assembled19" rack-mountableOutput controlFully discreteWarm Audio WA73 Specifications:80dB of gain – resistor-stepped gain switchTONE button – Changes input transformer impedance for varying tonePolarity switch48v phantom powerBoost/Cut controls:Low Band: 35, 60, 110, 220 HzMid Band: 360, 700, 1600, 3200, 4800, 7200 HzHigh Band: 10, 12, 16 kHzAdditional high band frequency EQ points added (compared to vintage 1073)4-position inductor-based hipass filter: 50/80/160/300 HzXLR mic inputs (front & back)Line-level TRS inputTS Send/Receive insert jacksXLR & TRS line-level outputsDirect In, instrument input1RU 19" rack-mountableOutput level controlLED level indicationFrequency response: 20Hz - 20kHz +/-.5 dBInternal IEC 115v/230v power inlet Warm Audio WA73-EQ Single-Channel British Mic Preamplifier + EQ.
