Warm Audio WA-67 Tube Large-Diaphragm 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.

Warm Audio WA12 MKII Single-Channel Preamplifier (Black)

Handle all of your single-channel audio recording needs with the black Warm Audio WA12 MkII, a preampliflier for professionals on a budget. This is a discrete, dual-transformer, high voltage mic pre that offers high headroom, a low noise floor, and sonics designed to impart a larger-than-life quality.

Based around an X731 opamp derived from the Melcor 1731, the pre offers a sound that can be warm or clean, saturated or transparent, depending on how hard you drive it. Drive it softly or hard, it won't change the essential sonorous quality of the unit.

It's also customizable for the DIY crowd: Because the unit was designed around the X731 opamp, the pre can accept any discrete opamp on the market that conforms to the 16V, 2520 pinout standard. In addition to the opamps, the WA12 MkII employs CineMag USA transformers, as well as other components that allow it to compete with units far more costly.

This preamp offers XLR and 1/4" connections for mic level, line level, or Hi-Z instruments. You'll also have your choice of XLR or 1/4" TRS outputs. A pad switch is on hand, as are a polarity switch and a button to supply 48V phantom power to condenser mics. A tone control lets you change the impedance from 600 to 150 ohms, which will have an effect on the sound.

Key Features at a Glance
  • Utilizes premium grade input and output USA CineMag transformers
  • 71 dB of gain, fully discrete signal path
  • Can be replaced with other 6-pin 2520-foot print opamps for varying tone/flavor
  • Tone button switches the input impedance from 600 ohms to 150 ohms, changing the tone of both the microphone and Hi-Z inputs
  • 2-megohm Hi-Z input on front panel, sends instrument signal through entire circuit including both Cinemag transformers and the discrete opamp
  • Suitable for guitars, bass, keyboards, and other instruments that have a 1/4" output jack
  • Output attenuation control (after the CineMag output transformer) allows for driving the preamp and transformers into saturation
  • LED meter gain indication
  • External power plug

Warm Audio Premier Series Balanced XLR Cable (15')

Presented here with a cable length of 15'', this Warm Audio Premier Series XLR Cable is designed to provide a high-end connection between balanced gear with XLR jacks, such as microphones, outboard equipment, and interface-to-monitoring connections. If you care about the details of your sound onstage and in the studio, use this cable to preserve your signal.

This XLR cable is chock-full of features that enable a top-of-the-line performance, such as gold-plated connectors and a star-quad wiring scheme for superior RFI rejection in the balancing process. Double-Ruessen shielding helps protect against EMI, and a braided outer wrap fights against tangling. To guarantee an optimal performance, Warm Audio partnered with Gotham AG, one of Switzerland's best producers of premium cable.

The Premier Touch
Warm's Premier cables go above and beyond, adding features like gold-plated connectors, a braided outer wrap, four-conductor star-quad construction (helping aid in giving you powerful rejection of RFI), and double-Ruessen shielding (also for increased rejection of EMI).
Braided Premier Wrap
This braided wrap removes the friction that occurs when rubber or PVC rub together, so it's much easier to handle and wrap the cable. No more fighting with a rat's nest of cable spaghetti. The braided wrap also adds an element of strength and reliability, as it helps to protect the cable's PVC jacket from damage due to pinching or binding.
Star Quad Explained
A traditional balanced cable uses three cores of wire to carry audio signals—one shielded core for the positive leg, one shielded core for the negative leg, and a plain outer wrap that functions as the ground. The idea is this: a fully balanced system flips the phase of the signal, merges the positive and negative signals together, and effectively cancels out interference encountered along the cable's length by throwing it out of phase with the audio.

Star-quad construction takes that concept even further by using five cores instead of three. Two cores are provided each for the positive and negative legs, as well as a single ground. This helps to further shield the audio from RFI (radio frequency interference), ensuring an even better performance.

Double-Ruessen Shielding Explained
Double-Ruessen shielding goes further than more traditional techniques in two ways: First, the cable is wrapped with two separate shields. Second, the outer shield is wrapped in a contrary direction to the inner shield, creating a stronger and more complete barrier from EMI for the internal cores.
Gold-Plated Connectors
Gold connectors have characteristics that are advantageous for signal transfer and provide more resistance to corrosion than other metals, making it well-suited for cable connectors.

So far so good. I haven't started serious recordings yet. I'm yet to see the magic of this mic. Will be back.

Great Microphone!

I love the microphone. It has the heavy feel of quality, it comes with a beautiful black velvet lined wooden box, and the sound is great. It has a warm sound quality with a well controlled high end response - not at all harsh or overly sibilant - very silky smooth on the high end and a warm low end response, even from a couple of feet away in cardioid pattern. However, there were a couple of minor quality control issues with the microphone. When I got it, the pattern select switch would not go into the Omni pattern, because the mic electronics cover was rotated, and tightened down, so that the switch would bump into the pattern switch cutout before it would go all the way into the omni - directional pattern. This was an easy and obvious fix, however, it should not have come from the factory like this. Also, the screw that locks the shock mount from rotating up and down, would not lock it. The reason was that there was some plastic flashing from the screw knob, molded into some of the threads of the locking screw, preventing it from tightening all the way. The fix required carefully removing the plastic from the threads. This, again, should not have come from the factory like this. But, when you consider the general quality and price of the microphone, these are. really, minor issues.
