Audio Dictionary: A: Attenuation nike air force 1 low, wastage of dB. AC (Alternating Current): An electrical current that sometimes alterations in magnitude and instruction. Acoustic Fiberglass: Thin fiberglass matter used as damping stuff inside speaker enclosures. Acoustics: The study of sound. Air Gap: The space separating the altitude plate and the pole chip. This is where the voice reel sits. Alignment: A level of enclosure parameters that provides the best performance for a woofer with a given worth of Q. Alpha: In sealed enclosure designs, the percentage of Vas to Vb, where Vb is the volume of the carton you ambition build. Alternator: A component that is rotated by a motor to produce AC voltage, which is then rectified (turned into DC) and used to supply voltage to the vehicle's electrical system. Ampere (A): The unit of measurement because electrical current in coulombs per second. There namely an ampere in a circuit that has a 1 ohm resistance while one volt is applied to the circle. Amplifier: An electrical circuit devised to boost the current Nike SB Blazers, voltage, or power of an applied signal. Amplitude: The comparative strength (usually voltage of a signal). Amplitude can be expressed as both a negate or affirmative number, relying on the signals creature likened. Attenuation: The rebate, usually along some controlled quantity, of an electrical whistle. Audio Frequency: The acoustic spectrum of person listening, generally regarded to be between 20 Hz and 20 kHz. B: Magnet flux density in breach. Baffle: A board or other airplane surface used to mount a horn. Balance: Same strength provided to both left and right stereo channels. Bandwidth: The range of frequencies covered by a driver or a network (crossover). Band-Pass Enclosure: Type of enclosure used for subwoofers where the driver is entirely inside the enclosure and all of the output emerges through a port(s) on one of the sides. They are difficult to think for optimum representation. Band-Pass Filter: An cordless circuit established to pass only a certain scope of frequencies. Basket: The metal frame of a speaker. Bass Blockers: First mandate high-pass crossover (non-polarized capacitors), generally accustomed aboard midbass or dash speakers to keep them from trying to rebuild deep bass which could abuse them by high playing levels. Bass Frequencies (Low Frequencies): The low end of the audio frequency spectrum. There are no real frequencies where bass is categorized, but it ranges from nearly under 20 Hz to 400 Hz. Bi-amping: Means that instead of driving a speaker full-range with a single aisle of amplification, through a unattached set of speaker cables, you actually connect two sets of cables, with each set driven by a detach amplifier, or divide channels of a multi-channel amplifier. This access, low frequencies and tall frequencies each receive dedicated exaggeration. |
