The displayed frequency response curve and polar pattern correspond to a typical production sample for this micro- phone. Each microphone comes with an individual 0° frequency response. The individual compensation curves for 0° and 90° free-field measurement can be requeed via the following link: www.beyerdynamic.com/mm1-regier Frequency response curve ± 1.5 dB MM 1 0 dB = 15 mV/Pa APPLICATION The MM 1 has been developed for the calibration of udio rooms, PA and ELA syems. In conjunction with a spectrum analyser, the sound pressure levels of loud

speakers can be checked in addition to frequency response measurements. Due to the slim housing with the protruding microphone capsule, the influence on the sound field is very low, so that a pressure build-up at high frequencies is moly avoided. The transmission pattern is selected so that an exactly linear frequency response is achieved with diuse sound input. This makes the calibration of several loudspeakers in the udio paicularly easy and fa. The MM 1 also provides valuable services when inveigating sound signals in research, development and indury.MM 1 — Condenser Measurement Microphone 5

Connection The MM 1 is equipped with a 3-pin XLR connector. You can connect it to any microphone input with phantom power (12 - 48 V) with a suitable microphone cable. Activate phantom power for this purpose. Caution: Carelessly laid cables are a trip hazard. People can be injured and the microphone can be damaged. Operation When setting up the MM 1, make sure that there are no large objects close to the microphone, which could influence the sound field and place the microphone clamp as far down as possible. Note on the calibration of loudspeakers in udio rooms: When measuring loudspeakers and other sound sources with a high direct sound level, you should set up the MM 1 so that the microphone axis is at 90° to the sound source (see illuration below). This ensures a linear recording with all frequencies. With direct sound input from the front, a slight pressure build-up becomes evident at frequencies above 10 kHz. This leads to a boo at high frequencies (refer to the frequency response curve at 0°). With lower frequencies, there is no pressure build-up and the polar pattern is exactly omnidirectional. Depending on the alignment of the microphone to the sound source, you should use the appropriate calibration file.

For tripods with a 5/8" thread, you can unscrew the threaded inse. Caution: A tripod with an insecure and can fall over and damage a microphone mounted on it. Make sure the tripod ands able. MAINTENANCE Use a so cloth moiened with water to clean the microphone sha. Make sure that no water enters the microphone. Do not use cleaning agents containing solvents.
