Product Description

The WA73 recreates the sound of the legendary 1073 British preamp. If there’s one preamp-EQ that professional engineers would unanimously agree has defined the tone of pop/rock records for the last 50+ years, it would most definitely be the venerable 1073. The 1073 has been massively used in recording and live applications for decades and is still considered to be the Holy Grail of preamps today.

When Warm Audio decided to release the WA73 Family it was imperative to them that the products pay respectful homage to the sacred British console history in both design and performance. The tone and sweet character that the vintage units impart is so unique and familiar, that Warm Audio had only the pure desire to release truly sonic accurate replicas. After years of R&D, careful reverse-engineering, and countless hours of auditioning, the WA73 Family has been born!

The WA73 Family of preamps are “Desert Island” boutique preamps but can also be classified as studio and live work-horses. The classic 1073 is known as a versatile tool that works with all kinds of microphones from Condenser, to Dynamic, to Ribbon. The WA73 Family 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’s no recording, mixing or engineering task the WA73 can’t handle.

Hand Wired, Hand Assembled:
The classic 1073 was hand-wired and so is the WA73 Family! Guru’s claim that a portion of the 1073’s classic tone can be attributed to the hand-wired nature of the build. The entirety of the WA73 Family of preamps is authentically hand-wired and hand assembled, including the PCB components that are all populated by hand.

UK Custom Carnhill Transformers:
1073 enthusiasts unequivocally get excited about the component history in these classic circuits. The signal transformers are a common topic of conversation. The classic vintage units used various versions of transformers throughout the years, and the most coveted were the very first versions made by Marinair Radar. Marinair Radar Transformers are regarded as the most desirable 1073 choice due to their fluid and forgiving nature. They saturate sweetly when pushed, and have been known to make engineers cry when they hear how beautiful their mixes sound through them! Warm Audio worked closely with Carnhill Transformers of Cambridgeshire, UK, to design faithful replicas of these most coveted, early version transformers. The entire WA73 Family proudly utilizes these fantastic Carnhill Transformers. We at Warm Audio have not yet heard a modern day 1073-style preamp sound as close to the early vintage 1073 design as do our WA73 Family units with these beautiful custom Transformers.

Capacitors & Signal Path:
An important part of these classic British circuits not often discussed is the different styles of capacitors and output transistor used. We found it important to maintain integrity to the original design 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 1073-style replicas.

Solid piece of gear.

Good piece of gear. Great sound for the price. Not as silky and smooth as I imagined but I also don’t have much experience using a true Neve 1073. I like it a lot on bass guitar. It’s great for vocals but I would say for more gritty use on hiphop vocals that are using more old school production.

Major Upgrade for my studio

Product Review

I've been using ua audio unison preamps which sound good but I knew I needed a outboard mic preamp, received it in the mail and got to work instantly!! I love the thing!! My vocal record sounds way thicker just like I needed it to be. My next piece of rack gear with be compressor and it will definitely be warm audio!!!

I Have An Apollo Twin And Use a Warm Audio Wa87 Now those two together sound amazing but adding this warm audio wa73 changed all my recording and mixes 10x better. I have a crisper cleaner sound. I couldnt tell you where my mixes would be with this new upgrade and I wouldn't have it without you great payment plan so thank you again for everything you guys do .

Almost got it right

Product Review

While this emulation gets close to the “warmth” of the original, the added/raised noise floor takes away from the usefulness of this pre.

Simply Amazing

Product Review

I paired this with my Neumann tlm49 to “UAD tubetech cl1b compressor” and vocals sound amazing. Warm Audio out did themselves on this one. Can a day sooner than expected too. I bought the UAD 1073 last year during the Black Friday sales. But this blows the plugin completely out of the water. And this is jus as good as the BAE 1073 units.
