Warm Audio
WAU WA47

Product Details

The Warm Audio WA-47 is an all vacuum tube, large diaphragm, transformer balanced, multi-pattern (9), large condenser microphone, based on the classic '47 that has been used on countless hit records for the last 50+ years. The WA-47 is designed for pro studio, home studio, live, and broadcast applications and sounds great on vocals, acoustic/electric guitars, acoustic/electric bass, drums, piano, strings, brass/woodwind instruments, and an array of other sources. The classic '47 became extremely popular in the 1960's and is now considered one of the greatest microphones ever made. The classic '47 is still widely used today in professional recording studios but have become extremely rare and expensive to acquire.As with all Warm Audio products, a focus on quality components ensures the best sounding product possible. The WA-47 is packed with top end components that are carefully sourced from many of the top pro audio component suppliers in the world.

True '47 Style Capsule

The WA-47 utilizes a custom reproduction of the vintage k47 style capsule that was used in the classic '47 microphone
- designed with the same hole pattern and frequency response. Every Warm Audio capsule is made in the same small assembly house in a clean-room environment, and packaged in its own protective jewel case until the moment it is loaded into the microphone. Each capsule is visually inspected and electrically tested for imperfections.A large part of any microphone's tone comes from its capsule, and the true k47 style capsule used in the WA-47 is not easily manufactured or typically found in affordable condenser microphones.

The Capsule

The WA-47 utilizes a custom reproduction of the vintage k47 style capsule that was used in the classic '47 microphone
- designed with the same hole pattern and frequency response. The Warm Audio version of this capsule (model# WA-47-B-80v) is carefully manufactured by an Australian capsule manufacturer whose precision and repeatability allows Warm Audio to nail the vintage sonics of the most important sonic piece of this classic style of microphone.

The Tube

A Slovak Republic JJ 5751 vacuum tube is a lower gain, low noise tube that forces much of the sonics of the capsule and transformer to be heard more significantly than some higher gain tubes might allow. The frequency response of the JJ 5751 and the way it contributes to the circuit is tonally smooth and vintage in nature.

The Transformer

The WA-47 utilizes an American made TAB-Funkenwerk (AMI) USA transformer with large core imported German laminations. This transformer helps provide the creamy smooth top end, and the LARGER THAN LIFE bottom end one would expect from a '47 style condenser microphone.

The Cable

One component of a tube microphone often overlooked is the 7 pin cable that connects the microphone to its power supply. When auditioning the WA-47 and other tube microphones Warm Audio learned quite a bit about 7 pin cables and how the shielding and wire gauge size can drastically change the sonics of a tube microphone. Warm Audio has partnered with Gotham Audio in Switzerland to use their very carefully built top-end 7 pin GAC-7 cable. Using this cable increases top end presence and the overall size of the recorded image in the stereo field, by reducing phase shift and the parasitic effect often found in poorly built cables. Gotham Audio is very expensive and boutique in nature and should not be considered a small addition to the WA-47 package.

The Capacitors

The WA-47 uses a polystyrene coupling capacitor for uncompressed top-end response from the capsule, wima film capacitors throughout, and an imported Solen French capacitor on its output driving the TAB-Funkenwerk (AMI) USA output transformer.

Delivery estimates for expedited shipping options are listed on the product page for the item in question. All expedited shipments are delivered Monday-Friday.

For APO/FPO customers, all orders ship via USPS. Expedited shipping is not available. Tracking for these orders is not available.

For customers shipping to a PO Box, the order may need to be shipped via USPS. For this reason, expected delivery dates cannot be guaranteed.

Do you ship to my location?

For most products shipping to the continental United States, customers may choose Ground, 2-Day Air, or 1-Day Air delivery. We also ship to Alaska and Hawaii; however, due to carrier restrictions, we cannot ground-ship to those states.

In addition, we ships to the following destinations, though some restrictions apply:

  • Canada

  • APO/FPO
  • U.S. Territories

See instructions below for how to search the site by our eligible shipping destinations.

Note: We cannot change a shipping address on an order after it has shipped. If an order is returned because it couldn't be received at the listed shipping address, we will accept the return but will not refund the shipping charges.

Canadian orders are charged in U.S. dollars. Actual charges are dependent on your bank's conversion rate. Your bank may assess additional fees for international orders.

Although items shipped to Canada receive their full factory warranty, they must be returned to a United States service center for repairs. We're not responsible for any shipping or customs fees incurred in such a case.

What about customs fees?

Please be aware of customs fees such as taxes and duties, which are not included in our shipping charges. Customs fees vary from location to location. Please check with your local customs office for more information on the fees in your area. If you refuse to pay these fees, your order will not be delivered. We cannot refund shipping charges if an item is returned due to refusal to pay fees, and a restocking fee may be applied to cover the cost of return shipping. Customs fees are non-refundable.

Immediate shipment is available Monday-Friday. A valid order placed before 5 p.m. EST will ship the same day when using Ground or Free 2-Day shipping. Ground and Free 2-Day shipping orders placed after 5 p.m. EST will ship the next business day. Many orders using an expedited shipping method (2 Day Air or Next Day Air), and placed before 10 p.m. EST, will ship the same day.

Shipment and availability information updates from our warehouse to our website almost in real time. We are highly confident of the status of each item when you view a page. However, we do not reserve inventory being viewed or even placed in shopping carts, so we cannot guarantee an item's availability until you have placed your order. In particular, if you have been in the checkout area for more than about 10 minutes, we do recommend that you refresh the page to get the most current inventory prior to checking out.

What is a valid order?

A valid order is for a valid item at a valid price, placed with a credit card with complete and verifiable address and other information. Details.

Does immediate shipment mean immediate delivery?

Once an order is shipped, our carriers (Federal Express and UPS) typically guarantee a service time for when the order will be delivered to you. Our carriers have a very good record of delivering at their promised service time. We will ship immediately, and on all items, we will refund expedited shipping charges if the carrier's service levels for your chosen shipping method are not met.

If a product is in stock, is there any reason it will not ship immediately?

Exceptions are very unusual, but here are some examples of reasons that might prevent us from shipping immediately:

  • Warehouse, call center, or web operations lose power or telecom connectivity.
  • Warehouse, call center, or web operations lose capability due to adverse weather (blizzard), safety threat, or other factors.

What can I do if I don't feel you've lived up to your guarantees?

If you ever feel we have not lived up to any of our guarantees, we want to know about it -- and we want a chance to do right if we agree. Contact Us.
