Warm Audio WA-67 Tube Condenser Microphone

Continuing their mission to bring quality recreations of classic microphones to the masses, Warm Audio have engineered the WA-67 to look, sound, and feel like an original ’67 microphone. That means the WA-67 is a tube-powered mic, complete with its own power supply and high-quality 7-pin cable, giving the user the ability to dial in cardioid, omnidirectional, and figure-8 polar patterns with heaps of vintage color.

Warm have taken great care in refashioning this classic microphone, using the proper EF86 tube and capsule, and fashioning it out of brass, just like the original. Top-shelf componentry was used throughout the design, from the caps to the transformer to the cable itself. The result is a smooth, buttery microphone that flatters most audio sources.

Whether you’re recording vocals, guitars, string instruments, or anything else, so long as you keep the audio under 138 dB of SPL (which is pretty loud) and restrict it to the human hearing range hearing (20 Hz to 20 kHz), you’ll enjoy a true-to-the-original vintage sound out of this microphone. The mic offers a 10 dB pad for loud sources and a switchable high-pass filter to mitigate some low-end rumble if need be. The WA-67 ships with a power supply, a 7-pin cable, a hardmount, and a shockmount. It also includes a wooden case.

A Legendary Capsule Recreated
Warm went to great lengths to recreate the capsule from the original ’67, making sure that their mic performs the same way, exhibits the same frequency response, and provides the same character as the original. This meant ensuring the hole pattern was identical, and crafting the entire assembly out of brass, down to the mounting rings.
Faithfully Use of EF-86 Tube
The EF-86 tube is well-known in the industry for having characteristics that are consistently flattering to audio sources, and it’s one of the reasons why the original ’67 microphone remains sought after (and why some modern audio manufacturers use it in their own hyper-expensive microphones and preamps). Warm knew that it was critical to implement it in the WA-67.
Top-Shelf Components
In order to accentuate and complement the custom capsule and EF86 tube, Warm used top-shelf components to complete their version of the original circuit, including high-bandwidth polystyrene capacitors as well as boutique polypropylene caps from Wima and a large output capacitor from Solen. They also used a custom large-core transformer from Lundahl in Sweden, which plays a significant role in the buttery smooth, high-frequency response and huge three-dimensional sound of the WA-67. The microphone is also encased in a beautiful nickel-plated brass body and headbasket, which provides strength and additional shielding from extraneous handling noise.
Attention to Details—Even the Cable
The quality of the 7-pin cable that connects a tube mic to its power supply is also of paramount importance. It carries both audio signals and voltage for the tube on different pins, which means it plays an integral role in the mic’s performance. That’s why Warm partnered with high-end manufacturer Gotham Audio of Switzerland, using their high-end GAC-7 cable with the WA-67. This special cable is integral to the sound and performance of the microphone, and adds the finishing touch to the WA-67 system.
