INTRODUCTION
The WA-84 is a small diaphragm condenser microphone based on classic microphone circuitry. The WA-84 is a fully discrete Class A design that utilizes a CineMag USA transformer, polystyrene and Wima capacitors and a Fairchild FET. The WA-84 is designed for pro studio, home studio, live, and broadcast applications and sounds great on a variety of instruments and sources, such as; acoustic/ electric guitars, acoustic/ electric bass, drums, piano, strings, brass & woodwind instruments, and an array of other sources. The WA-84 has a very LARGE sound for it’s small size and uniquely uses a heavy Nickel CineMag transformer in it’s signal path to warm up and ENLARGE sound sources. Small diaphragm condenser microphones have widely moved to transformer-less technology in recent years for ease of design and a lower-cost manufacturing process. When designing the WA-84 we chose to go the extra mile and tackle a more boutique design known for it’s it’s crystal clear, yet smooth, LARGE sound. We are proud to offer something special to the market-place by using large core transformer technology (CineMag USA) in a small diaphragm condenser microphone package. The result is a circuit that we feel sounds absolutely gorgeous and goes the extra mile in terms of signal integrity and smooth boutique tone.
A LOOK INSIDE THE WA-84
The CapsuleThe WA-84 utilizes a custom vintage-style capsule designed to emulate classic componentry and design techniques. The WA-84’s capsule is carefully manufactured by an Australian capsule supplier and is precisely reproduced to vintage specs. We are pleased to offer such a high quality capsule in this microphone which allows us to nail the sonics of the most important component of any microphone.
The CircuitThe WA-84 1s a fully discrete Class A design that utilizes a CineMag USA transformer, polystyrene and Wima capacitors and a Fairchild FfT.
The TransformerThe WA-84 utilizes an American made CineMag USA transformer that contributes to the legendary creamy smooth top-end and the BEEFY mid to bottom-end one would hope to get from an 84-style small diaphragm condenser microphone.
The CapacitorsThe WA-84 proudly utilizes Wima, polystyrene and tantalum through-hole capacitors throughout.
FEATURES
- ContentsThe WA-84 package includes the WA-84 Microphone, Cardioid Capsule, Shock-mount, Mic Clip, Windscreen and Carrying Case.
- Cardioid CapsuleThe included cardioid capsule comes mounted to the microphone. It is replaceable and can be screwed and unscrewed from the microphone.
- -10dB Pad SwitchThe -10db pad switch attenuates the incoming signal right after the capsule, but before it reaches the rest of the microphone circuit. The pad switch has a 0dB and -10dB position.
- XLR OutputA Gold-Plated 3 pm XLR male connector is located at the base of the WA-84 microphone. The microphone’s signal will exit this connector. Connect this connector to a preamp via a standard 3 pin XLR microphone cable.

TIPS AND INSTRUCTIONS
MICROPHONE PLACEMENT & SPACING
When it comes to distancing a microphone from its sound source, one may think of this process, among other things, as choosing a desired ratio of original sound source to reflections and acoustic space. The closer to the source, the less space and ambience will be captured. In some cases, this is fully desirable; and ambience will be added in later via the magic of digital delay and reverb. In other cases, natural acoustics are critical. A great illustration of this is the recording of a gunshot or cannon fire: at very close range, the sound is surprisingly thin; however, at a distance, the sound becomes more full and explosive. This is a great reference to keep in mind; because to some degree, this phenomenon holds true with anything where natural acoustics is an important part of the sound, most notably with percussion. Beware that all processes do have boundaries and microphones do have a maximum SPL level they can be subjected to without distortion. Both microphones and preamps have a signal to noise ratio that tends to get poor in cases where more gain is required to make up for a distant signal. It’s generally good advice to place a microphone about 12 inches from a source, and to fine-tune it from there until you have exactly what you are looking for.
A BRIEF WORD ON ROOM TREATMENT
Room acoustics can be just as important as the microphone you choose. Even the best microphone won’t sound great if you are picking up unwanted reflections that can smear or comb filter the sound you are recording. Just because a microphone is set to cardioid pattern, does not mean that it is not picking up unwanted room reflections or outside noises such as street traffic, footsteps, or air conditioning vents.Though a walk-in vocal booth is hardly necessary for most situations; a good quality ‘vocal shield’ type product can make an enormous difference, often making the difference between a demo quality and a professional quality recording. Likewise, when recording combo amps and other instruments, using gobos or other acoustic isolation products can be hugely beneficial. Getting proper isolation, and just the right amount, but not too much room ambience is one thing that really cannot be effectively corrected later in the process. It is of the utmost importance to put in the extra time to set things up well in the beginning.
SIGNAL INTEGRITY
In professional audio a chain is only as strong as its weakest link. When it comes to microphone cabling, a quality cable can make a big difference. Though not as critical as with instruments or dynamic microphones, a thin, poor quality, or worn XLR cable can affect the sound of a microphone.With extreme age or wear, gaps can form in the foil or spiral shield of a microphone cable, allowing RFI and EMI to leak through, or shield wiring can begin to make intermittent contact with the signal wire. XLR pins can corrode after many years of exposure, or solder joints break at the stress points inside an XLR barrel. Occasional cable testing and maintenance is good practice, and worn XLR pins can often be given new life (if not past the point of no return) by spraying liberally with a contact cleaner such as DeOxit and worked through several insertions. It is good practice to not use a cable much longer than what is needed for the job at hand; if a 20 ft. cable will work, little good can come from using a 35 ft. cable. Though condenser microphones are far better equipped to survive longer or lesser quality cable runs than dynamic and ribbon mics, audio can begin to attenuate or become contaminated beyond a certain threshold.
When recording vocals, it’s a good idea to use the nicest pop filter you can afford. This not only protects the microphone; it protects the recorded tracks by keeping plosives {a clipping that occurs from sudden air pressure on the capsule) to a minimum. Pop filters can also be creatively used in other situations where sudden air pressure changes can occur, which include large loudspeaker movement, the sound hole of a kick drum, or the gap between the two brass pieces of a hi hat cymbal. As a general rule, a higher quality pop filter will have less audible impact on the sounds passing through them; while less expensive, improvised, or foam windscreen type filters can sometimes have a muffling effect on high frequencies.
Microphone placement is as much an art as it is a science, and takes a great deal of patience, attentive listening, and trial and error. The more music you record the greater instinct you will have for knowing which microphones to first try for given situations, and how to place them.
One thing to keep in mind is that what a microphone hears will often be radically different from what a casual observer hears when standing several feet back from where a microphone is. It’s good practice to get down and put one’s ear close to a speaker cabinet or right in front of a bass drum’s resonator head, and hear what that microphone is hearing from its position. Get a sense for how different your source sounds close up, farther back, and from different angles. Begin to move a microphone around very slowly and listen for the changes in sound that you get. Notice how a small change in mic position can make an under-snare microphone go from bad to good.
Notice how moving a guitar cabinet mic further to the side of the center cone, or further off axis will affect the sound.
