Description

The WA273 is a ‚ÄúDesert Island‚Äù boutique preamp, but it can also be classified as a studio and live work-horse. Classic ’73-style preamps are known for being versatile tools that work with all kinds of microphones from Condenser, to Dynamic, to Ribbon. The WA273 equally shines on all types of microphones and sources including; vocals, acoustic/electric guitars, bass, drums, percussion, orchestras, keyboards, and even as a tone shaping tool to run partial or complete mixes through. With 80dB of gain and a fully discrete Carnhill Transformer balanced signal path, there‚Äôs no recording, mixing or engineering task that the WA273 can‚Äôt handle.Features UK Custom Carnhill TransformersWarm Audio worked closely with Carnhill Transformers of Cambridgeshire, UK, to design faithful reproductions of these most coveted, early version transformers. We at Warm Audio have not yet heard a modern day ’73-style preamp sound as sweet and musical as does our WA273 with these beautiful custom Transformers. Capacitors & Signal PathAn important part of classic British tone not often discussed are the different styles of capacitors and output transistor used in ’73-style circuits. We found it important to maintain integrity to early British designs by using tantalum and polystyrene capacitors in the signal path and an output transistor choice that is much smoother in the high gain settings than what is typically found in modern ’73-style preamps. Hand Wired & Hand AssembledClassic ’73-style preamps were often hand-wired and so is the WA273! Guru‚Äôs claim that a portion of the sought after classic British tone can be attributed to the hand-wired nature of the build. The WA273 is hand-wired and hand assembled, including the pcb components that are all populated by hand.SpecificationsDUAL CHANNEL, CLASS A, ’73-STYLE BRITISH MICROPHONE PREAMP UK MADE CARNHILL TRANSFORMERS HAND WIRED, HAND ASSEMBLED 80DB OF GAIN – RESISTOR STEPPED GAIN SWITCH FULLY DISCRETE TONE BUTTON – CHANGES INPUT TRANSFORMER IMPEDANCE FOR VARYING TONE POLARITY SWITCH 48V PHANTOM POWER 4 POSITION INDUCTOR BASED HIPASS FILTER – 50, 80, 160, 300 HZ XLR MIC INPUT LINE LEVEL TRS INPUT TS SEND/RECEIVE INSERT JACKS XLR & TRS LINE LEVEL OUTPUTS DIRECT IN, INSTRUMENT INPUT FREQ RESPONSE 20HZ – 20KHZ +/-.5 DB 19 RACKMOUNTABLE INTERNAL IEC 115V/230V POWER INLETWatch: Warm Audio // WA73 Single Channel British Mic Pre Getting Started
