The Audio Technica 4033/CL:

This impressive side-address Cardioid condenser microphone broke the barrier in its class when it was released. This new version of the critically-acclaimed AT4033, the AT4033/CL, is a studio classic and favorite that boasts low-noise, symmetrical, transformerless circuitry that results in exceptional transient response and clean output signals. From drum overheads to vocals, from guitar cabinets, broadcasting, and woodwind sections, the AT4033/CL is certainly a versatile microphone. A solid presence defines the sonic signature of this 40 Series pro-audio microphone. The AT4033/CL’s 80Hz high-pass filter seamlessly switches between flat frequency response and a low-end roll-off that virtually eliminates ambient noise and popping (aka "plosives") normally present in close-proximity vocals and dialogue.

  1. The 2-micron-thick, vapor-deposited gold diaphragm undergoes a five-step aging process so the optimum characteristics achieved remain constant over years of use.
  2. Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity.
  3. Floating-construction capsule assembly provides isolation from noise and vibration.
  4. Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections.
  5. Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of highspeed transients.
  6. State-of-the art surface-mount electronics ensure compliance with A-T’s stringent consistency and reliability standards.

Microphone Specifications

Microphone Type
This is the type of microphone included with the purchase of the item.

Wireless:All of these microphones can be used without the necessity of wires or cables to connect them. They usually come with a receiver that connects to the input device where the audio signal is being sent.

Shotgun: These microphones are suspended on a boom and are used primarily in video production and broadcasting.

Lavaliere: These microphones are clipped on to the lapel or tie of the talent for broadcast and video production audio.

Table Top: These microphones are designed with a built in stand or to be placed on a table top stand to be used for broadcasting and podcasting applications.

Headset: These microphones are to be worn on the head typically for live performance and theater production.

Handheld: These microphones are held in the hand and are used in a wide range of applications primarily vocals and public address.

Clamp On: These microphones attach directly on to an instrument.

Drum Package: These microphones are an all in one package for drums typically made of dynamic Kick, Snare, Tom, and a stereo condenser pair of overhead mics for Cymbals.

Designed Applications
The intended application the microphone is designed for.
Number of Microphones
This is the number of microphones that are included in the package.
Polar Patterns
The polar pattern of a microphone determines how sensitive it is to receiving sounds as they arrive at different angles.
Transducer Type
The transducer type is the manner in which the audio signal is converted into an electrical signal.
The configuration of the capsule determining on which side the microphone is sung or spoken into.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
Maximum Sound Pressure Level
This is the maximum sound pressure level that the microphone is capable of accepting and transferring into an electrical signal.
Output Impedance
This is the amount of impedance that the microphone allows.
A pad is a term used for built in attenuation in a microphone or pro audio channel strip.
Roll Off Filter
A low frequency filter found on microphones commonly expressed with a threshold in Hz and a slope in -dB/Octave.
Power Requirement
Condenser microphones require an external power source to operate. Typically a +48v DC charge commonly refereed to as Phantom Power.
Connection Type
This is the manner in which the microphone connects to the source unit. For wired microphones, this is the connector that directly connects the microphone to the mixer (or other input source unit). For wireless microphones, this is the connection that connects the microphones receiver to the mixer (or other input source unit).
The overall length of the microphone.
Diameter (inches)
A straight line running from one side of a circle or other rounded geometric figure through the center to the other side, or the length of this line

Wireless Specifications

Carrier Frequency Range
The frequencies of radio waves used by wireless communication transmitters and receivers. VHF 30 to 300 MHz, wave length 1 to 10 m UHF 300 to 3000 MHz, wave length 10 to 100 cm
Operating Range
The maximum span of distance between The Transmitter and Receiver.
Number of Channels
The number of different frequency Channels that a wireless microphone system is capable of using.
Transmitter Type
The type of transmitter in a wireless microphone system.
Receiver Type
The type of receiver used in a wireless microphone system.
True Diversity receivers have two radio modules and two antennas. Diversity receivers have one radio module and two antennas, although some times the second antenna may not be obviously visible. Non-diversity receivers have only one antenna.
