The QTC Series (Quiet Time Coherent) is designed for recording quieter sources such as vocals, strings and distant miked orchestras or choirs. These low-noise omnis are also an excellent choice for drum overheads, close-miked wind and percussion instruments. Earthworks’ reputation for realism is based on these distinctive omnis. Time Coherent Response means these models do not smear the time domain as most microphones do.With a frequency response to 40kHz and excellent impulse response, it will reproduce sounds with incredible detail that are true and life-like, making it an ideal and affordable choice for recording applicationsPerfect for recording the accuracy and full detail of instruments in the studio yet robust and subtle enough to record bird sounds in the jungleIntended for detailed sourcesOmnidirectional polar patternFlat frequency response, fast impulse response and exceptional polar characteristicsAccurate and uncoloredHandles sound levels up to 142dB with no proximity effect or handling noiseRequires 48V Phantom Power

The Quiet Time Coherent QTC50 is an exciting new addition to the Earthworks microphone line. It has all of the exceptional attributes of our popular QTC40 (same as QTC1). The QTC50 has an extended high frequency response to 50kHz and better impulse response. This microphone is for the sterling purist who demands the very highest quality. The QTC50 is it!

The MM 1 is a measurement microphone which has been designed specifically for measuring sound reinforcement and PA-systems. It is designed to work with spectrum analysers for measuring frequency response and sound pressure levels of loud speaker systems. The MM 1 is the ideal microphone for the measurement of audio signals in the research, development, for reverberation testings and other applications. The narrow tubular construction ensures that the microphone has negligable influence on the sound field so that an increase in sound pressure is avoided with high frequencies. A natural reproduction is achieved due to the linear frequency response. Features:Linear frequency response in the diffuse field / under 90°Omnidirectional polar patternCalibrated open circuit voltageNarrow tubular constructionSpecifications:Frequency response : 20 - 20,000 Hz(50 - 16,000 Hz ± 1.5 dB)Polar pattern : Omnidirectional,diffuse field calibratedOpen circuit voltage at 1 kHz:  15 mV/Pa (= -36.5 dBV) ± 1 dBNominal impedance : 330 ΩNominal load impedance : ≥ 2.2 kΩMax.

4090 Omni Mic, Hi-Sens, P48  natural and open sound suitable for instrument miking applications in the studio or on the stage lends itself to acoustic guitar, strings, piano and wind instruments The DPA 4090 is a high quality omnidirectional condenser microphone. Due to its uniquely natural and open sound, the 4090 is suitable for instrument miking applications in the studio or on the stage. The 134 dB SPL handling means it can be used with essentially any instrument from acoustic guitar and strings to piano and wind instruments. Due to their remarkably linear frequency response in the 20 Hz to 20 kHz range, sound system engineers can also use these mics for sound system alignment, testing and tuning. The rugged and compact design features a 5.4 mm diameter pre-polarized condenser capsule in a tapered body measuring just 12 cm (4.75 in).

The M30 is the standard for field and laboratory acoustic measurements. It features a very uniform frequency response and excellent impulse response.

Earthworks has become the accepted standard for affordable, reliable reference and measurement microphones. These microphones are accurate in the time domain and frequency response. Earthworks measurement microphones are optimized for clean, very fast impulse performance to provide accurate wideband response. They have virtually no handling noise and are remarkably stable with respect to temperature and atmospheric conditions. Our M Series measurement microphones are used by SMAART™, MLSSA™, Spectrafoo™, TEF™ and RTA in addition to acoustic measurement systems manufactured by dbx, DEQX and others. All models are available in matched pairs. The Earthworks M30 is a very cost effective reference microphone for SMAART™, MLSSA™, Spectrafoo™, TEF™ & RTA and all “audio band” measurements. It has a flat frequency response, fast impulse response and exceptional polar characteristics. Requires 48V phantom power.  Designed to work with laptop computers, this battery operated version of the M30 has a built-in preamp with a +14dB gain switch. The Earthworks M30BX Specifications:Frequency response: +-1dB 9Hz to 27kHz, +1/-3dB 5Hz to 30kHz Polar Pattern: Omnidirectional Sensitivity: 8mV/Pa (-42 dBV/Pa) Power requirements: 48V phantom, 10mA Max acoustic input: 150dB SPL Peak output voltage: 10V Output: XLR intended to drive a balanced transformerless input (pin 2+) Min output load: 600ohms between pin2 and 3 Noise: 27dB SPL equivalent (A weighted) Dimensions (LxD): 229mm x 22mm (9 x .860 inches) Influence of magnetic field: 80A/M induces less than 52dB SPL equivalent

The quality of a job ultimately depends on the quality of the used tools. For such a critical task as the measurement of the frequency response, only absolutely reliable tools can be used. With Behringer's ECM8000 they give you the possibility to achieve this.The ECM8000 can be used with nearly any Real-Time Analyzer that provides a phantom power within +15 V to +48 V. Due to the ultra-linear frequency response of the microphone, the analyzer only gets the signal that is in the room.Rely on your ears and on the ECM8000.FeaturesSophisticated electret condenser measurement microphoneUltra-linear frequency response for absolute measurement-precisionEvenly weighted, true omnidirectional patternPhantom powered +15V to +48VRugged construction and sleek, modern designLow Noise XLR output with gold-plated contactsPerfect in combination with our Ultra-Curve DSP8000ApplicationsFor checking the frequency response characteristics of studio control monitors, PAs, and similarAutomated room measurements in combination with the Ultra-Curve DSP8000As a or room-microphone for recordingTechnical InfoType: electret condenser, omni-directionalImpedance: 600 OhmsSensitivity: - 60 dBBandwidth: 15 Hz to 20 kHzConnector: gold-plated XLRPhantom power: +15 V to +48 VWeight: 120 g, approximately

The PRM1 Precision Reference Microphone is a special type of condenser microphone that provides an accurate reproduction of a room's sound characteristics for use with audio-analysis tools such as real-time analyzers (RTAs) and spectrographs.A reference, or “measurement,” microphone is condenser microphone that is designed to provide an accurate reproduction of a room's sound characteristics for use with audio-analysis tools, such as real-time analyzers (RTAs) and spectrographs. While measurement microphones can be quite expensive, the affordable PreSonus®PRM1 delivers high-quality results.The PRM1 employs a ¼” pre-polarized electret-condenser capsule and requires phantom power. It has an omnidirectional polar pattern, meaning it is equally sensitive in all directions. This allows the microphone to measure reflections, as well as direct signals, providing an accurate depiction of the room. This mic can handle up to 132 dB SPL and exhibits linear (“flat”) frequency response between 20 Hz and 20 kHz, so it won’t color the sound.Specifications:Type: CondenserPick Up Pattern: Omnidirectional Frequency response: 20 Hz to 20 kHz Sensitivity: -37 dB/Pa (14 mV/Pa) 1 Pa=94 dB SPLΙmpedance: 200ΩDimensions: W21 mm x L192mm Weight: 150g
