  In audio, a device to convert sound to electrical energy or vice versa. Microphones and loudspeakers are two type of transducers. Also refers to the portion of a microphone that is directly involved with conversion of sound energy to electrical energy. A phono cartridge also is a transducer, one that converts mechanical energy (vibration of the stylus) into electrical energy.

Specifications

• Definition of Frequency Range:] body=[
  

  The actual range or span of frequencies from low to high that a unit can pass or reproduce. In terms of audio recording studios, this is usually limited to the range of 20 Hz to 20,000 Hz, which represents the full range of human hearing.

  ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>Definition of Frequency:] body=[

  The number of times a periodic waveform cycles, or repeats, over a period of time.

  ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>Frequency Range (-10 Definition of dB:] body=[

  The decibel (dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity (usually power or intensity) relative to a specified or implied reference level. Since it expresses a ratio of two (same unit) quantities, it is a dimensionless unit. A decibel is one tenth of a bel (B).We perceive loudness of sound as the logarithm of the actual sound intensity, and dB (decibels) are a logarithmic scale.

  ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>dB) : 80 Definition of Hz:] body=[

  A unit of measure of the frequency of a vibrating object, such as a guitar string, speaker cone or electrical signal. Equivalent to cycles per second, it is named for Heinrich Hertz and abbreviated ” hz.>] cssheader=[boxoverheader] cssbody=[boxoverbody]”>Hz -20 Definition of kHz:] body=[ Kilohertz, 1,000 Hertz, or one thousand cycles per second. ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>kHz Definition of Frequency Response:] body=[ (Example, 30-20,000 Hz) Describes the audible range of frequencies that an audio system will reproduce. (Note: All else being equal, the lower the low number, the better the bass response and the higher the high number, the better the treble response.) ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>Definition of Frequency Response:] body=[ The actual range or span of frequencies from low to high that a unit can pass or reproduce.

Definition of Pink Noise:] body=[ A test signal comprising random noise that has been shaped to provide equal intensities of sound in each octave band. Pink noise is used for test signals because its spectral balance closely compensates for the frequency sensitivity of the human ear. ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>Pink Definition of Noise:] body=[ In sound production, noise can be classified as hum, buzz or hiss, crosstalk or digital hash. ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>Noise, 300W Program, 600W Definition of Peak:] body=[ The opposite of dipping. A peak is an EQ curve that looks like a hill, or a peak. Peaking with an equalizer amplifies a band of frequencies. Peaking also can refer to a very strong signal in an audio path that is overloading or clipping. ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>Peak Definition of Impedance:] body=[ Electrical impedance, or simply impedance, describes a measure of opposition to alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. When the circuit is driven with direct current (DC) there is no distinction between impedance and resistance; the latter can be thought of as impedance with zero phase angle. ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>Impedance : 16 Definition of Ohms:] body=[ The unit by which resistance to electrical current is measured. From Ohm’s Law (Current=Voltage/Resistance, or in other words, Current=Voltage/Ohms), a mathematical expression of the relationship between these three elements. It is also symbolized by the Greek capital letter omega (Ω). ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>ohms Coverage Pattern : 90 x 90 Dimensions (H X W X D) : 241.3 x 150.3 x 177.8mm (9.5 x 5.9 x 7.0in) Weight : 4.7 kg (Definition of 10.5:] body=[ ] cssheader=[boxoverheader] cssbody=[boxoverbody]”>10.5 lb) Related products Sale!
