What Is a Condenser Microphone?
The heart of the best condenser microphones (the capsule) is essentially a capacitor, “condenser” being the original term. It comprises two parallel plates spaced closely together. A stationary solid backplate is made of brass or other metal. The diaphragm is the movable front plate, ideally gold-sputtered Mylar or thin aluminum foil.
In microphone manufacturing, “sputtering” is the process of vaporizing metal to coat the diaphragm with an extremely thin film. Gold is preferred because it’s an ideal electrical conductor.
An electric charge is applied between the diaphragm and backplate to form a capacitor. The diaphragm moves in reaction to sound pressure variations, changing the capacitance. A preamp converts the capacitance to a varying voltage.
Sensitive & Quiet
Condenser microphones have an excellent high-frequency response, typically flat from 20 Hz to 20 kHz. They’re also very sensitive to pressure variations, ideal for vocals and instruments but not for extreme close-miking. And they’re quiet because they don’t have electromagnetic coils to pick up hum.
Unlike dynamic mics, all condenser models require external power. Some include an external power supply, while others can be “phantom powered” through the cable from the mixing console or audio interface.
But They’re Not Perfect
Condenser mics are relatively fragile. Although they can handle high sound levels, dynamic mics are preferred onstage, where accidents can happen.
They’re also significantly more expensive. The best condenser mics once cost the equivalent of thousands of dollars. Fortunately, many leading manufacturers have re-engineered their classic designs to put them within the reach of project studios.
Let’s now examine some features of condenser mics more closely.
Large versus Small Diaphragm
Small condenser diaphragms are typically less than about 1 inch (25 mm) in diameter. The mic case usually has a pencil shape, and it’s “top-address” (primary sound pickup is on top). A smaller diaphragm has lower mass, producing cleaner transients and better high-frequency response. However, they’re less sensitive, so they have a lower signal-to-noise (S/N) ratio.
These mics can be hand-held or mounted on a stand. They’re typically used for piano, acoustic guitar, strings, drums, and cymbals. In matched pairs, they’re ideal for overhead or room miking of drums, orchestras or choirs.
Larger & Heavier
Large condenser diaphragms are generally 1 inch or more. Mics with large diaphragms are physically larger and heavier, and are almost always “side-address.” The higher diaphragm mass equals a lower resonant frequency, typically adding some bass boost but reducing high frequency and transient response.
It also moves further in response to sound waves, creating a stronger audio signal. This makes them more sensitive, with a higher S/N ratio.
A disadvantage of large-diaphragm, side-address microphones is that their larger grilles allow short wavelengths to bounce around inside the casing. If not properly damped, this can cause erratic high-frequency response. And because they’re heavier, they’re usually either suspended in a shock mount on a sturdy mic stand, or in a desktop stand. They’re the preferred choice for vocals and solo acoustic instruments.
Analog vs. Digital
All microphones are essentially analog devices, converting sound waves into electrical signals. However, some microphones have built-in analog-to-digital converters (ADCs) to output a digital signal, usually through a USB interface. In theory, any microphone can become “digital” by adding an ADC before the output.
Digital mics are easy to use with computers, often plug-and-play with no driver software required. No external ADC is needed. They usually include zero-latency headphone monitoring. And digitizing the signal close to the mic can reduce electromagnetic interference. They’re an effective solution for podcasting or other solo mic applications.
A digital microphone can usually be used only by itself, because the computer sees it as an audio interface. And they can’t easily be connected to analog gear. For these reasons, analog microphones are still the norm, even for digital recording.
Most microphones pick up sounds coming from different directions unequally. Mic specification sheets usually include a “polar graph,” illustrating sensitivity to sounds coming from all around. This response varies somewhat by frequency.
By far, the most common polar pattern for vocal and instrument mics is the “cardioid” pattern, so-called because it resembles a heart shape. Cardioid mics are much more sensitive to sounds at the front than at the sides and back. Small-diaphragm mics are almost always cardioid.
Some large-diaphragm mics have multiple capsules to provide additional pickup patterns. Variations of the cardioid pattern design include half-cardioid, super-cardioid, and hyper-cardioid, with greater rejection of sounds from the side. Other common patterns include omnidirectional and figure-8.
Frequency response is the range of frequencies, in hertz (Hz) or kilohertz (kHz), to which a microphone is sensitive. To be useful, this has to be qualified by a variation in decibels (dB), for example: 20 Hz – 20 kHz +/- 3 dB. In reality, many mic manufacturers provide only the overall range, so a frequency response graph can be valuable.
Professional condenser microphones generally claim a response of 20 Hz – 20 kHz, unless specifically noted otherwise. Some have dips or peaks within that range that give them a unique sonic signature.
Maximum Sound Pressure Level
Maximum Sound Pressure Level (SPL) is the loudest sound a microphone can handle without severe distortion or damage. This value is expressed in dB. Condenser mics have maximum SPL values of about 120 – 150 dB.
A microphone’s sensitivity is a measure of its output relative to a standard sound pressure level (SPL). It’s usually specified in decibels relative to 1 volt output (dBV). It’s calculated with a 1 kHz sine tone at an SPL of 94 dB or 1 pascal (Pa). The result is always a negative number, so the closer it is to zero, the more sensitive the mic is. Sometimes this value is expressed as millivolts per pascal (mV/Pa), but we’ve made conversion here.
A mic with higher sensitivity can pick up quieter sounds. This might or might not be a good thing, depending on the situation.
Signal & Noise
There are two standard measurements for microphone noise. The first is referred to as “self-noise,” “equivalent noise level,” or simply “noise”. This is the amount of hiss and other random sound created by the microphone circuit itself, and it ultimately determines the quietest sound that can be cleanly recorded.
It’s measured in decibels with an “A weighting” to correspond to the ear’s sensitivity, abbreviated dBA. Most condenser mics have very low noise, 5 – 20 dBA, so you can capture the softest nuances of a sound.
The other specification commonly encountered is the signal-to-noise ratio (S/N). This is simply the ratio of an SPL of 94 dB (1 Pascal, remember?) to the self-noise level. S/N is not the same as dynamic range, which is always much higher.
Next, we have a few other details you should consider when purchasing:
Pads & Switches
Many microphones have switches on the body to modify their behavior. An attenuator or pad reduces the sensitivity by 10 or 20 dB so you can record a higher-SPL source. A bass (high-pass) filter cuts the bass response to reduce rumble or the “tubby” sound of someone too close to the mic.
Bass filters usually have a slope of 6 or 18 dB octave at around 80 to 150 Hz. Some mics provide multiple filter options.
What’s In The Box?
To use and protect your condenser microphone, you need a few extras. Obviously, you’ll need a cable with XLR or USB connectors, and a case or pouch to store and transport it.
Other accessories you’ll probably need if they’re not included are a mic stand swivel mount, a windscreen, and a pop filter. For a large diaphragm mic, you’ll also need a high-quality shock mount. And a separate power supply is necessary if your mixer doesn’t provide phantom power.
And last, but definitely not least…
Price: Value Versus Prestige
Classic name-brand microphones enjoy a special status in studios. Musicians who know their way around a studio appreciate being recorded with your most celebrated and expensive mic. Fortunately, many of the leading brands have re-engineered their best models, producing mics with nearly the same performance for less cost.
Depending on your specific involvement in the recording business, you might consider owning at least a few premium microphones for special occasions. Then round out your collection with condenser mics from manufacturers that offer high performance without destroying your equipment budget.
So here’s our selection of condenser mics for you to consider…
