Back Light:-In receivers, a display may be lit from the rear to create better visibility under a wide range of ambient light conditions. 2. Back Plate-The part of the woofers metal Basket or frame on which the Magnet structure is mounted. 3. Baffle:-A flat panel that divides the front and rear sound waves produced by a woofer. Sometimes baffle is used to mean an enclosure or the front panel on which the speaker is mounted . 4. Baffle:A surface used to mount a loudspeaker. 5. Balance: 6. Balance 7. Balanced 8. Balanced Transmission System-A circuit topology that maintains an equal impedance between both conductors and ground. A balanced transmission must have three basic elements 9. Balanced Transmission System: 10. Balanced wiring:-Audio line signals require two conductors. In an unbalanced line, the shield is one of those. In a balanced line, there are two internal wires plus the shield. For the system to be balanced requires output transformers and usually employs XLR connectors. Balanced lines are less apt to pick up external noise. This is usually not a factor in home or car audio, but is a factor in professional audio requiring hundreds or even thousands of feet of cabling. 11. Banana Jacks & Plugs-A set of connectors in which 4 spring contacts are wrapped vertically around a central pin like a banana peel. When inserted into the receptacle jack it maintains a strong and consistent contact. This type of connector is highly regarded as an excellent and reliable interconnector for cables between amplifiers and speakers. 12. Band-limiting filters: 13. Bandpass:A filter that transmits a certain frequency band and attenuates frequencies that lie on both sides of that band. (e.g., My friend's installer used a bandpass filter to send just the mid range frequencies to his 6-inch speakers.) 14. Bandpass-A filter that transmits a certain frequency band and attenuates frequencies that lie on both sides of that band. (e.g., My friend's installer used a bandpass filter to send just the mid range frequencies to his 6-inch speakers.) 15. Bandpass (box or enclosure) 16. Band-pass Enclosure 17. Bandpass filter: 18. Band-pass filter 19. Bandpass Gain:-The increase (or decrease) in efficiency of loudspeakers, due to the enclosure size and tuning. This is measured by the midband sensitivity of the speaker as a whole. 20. Bandwidth:Abbr. BW The numerical difference between the upper and lower -3 dB points of a band of audio frequencies. Used to figure the Q, or quality factor, for a filter. 21. Bandwidth: 22. Barium Ferrite 23. Basket 24. Bass-The portion of the audible sound spectrum that contains the lowest frequencies. These frequencies have the longest wavelength and require considerably greater electrical power to render them at their original strength. In a good modern speaker system, the bass portion of the response curve extends from as high as 500 hertz, down to 20 Hz. 25. Bass Blockers-Commercial name for auto-sound first order high pass crossovers (non-polarized capacitors), generally used on midbass or dash speakers to keep them from trying to reproduce deep bass. 26. Bass Boost/Enhancer Circuit: 27. Bass Reflex: 28. Bass Reflex (box or enclosure):-A speaker box design that makes use of a port or Passive Radiator which allows the energy derived from the motion of the back of speaker cone to be redirected in such a way as to reinforce the front radiation. This smooths and extends the low frequency response, but the effect is sharply Rolled Off on the low end, as the port signal goes back out of phase with the front. The overall effect of this is to tune the bass response to a particular point on the lower end of the spectrum, below which it rolls off sharply. 29. BBE 1 & 2 Processing-A signal processing circuit that provides improvements in imaging and spatial realism by altering the frequency and phase characteristics of portions of the input signal. 30. Beaming-A tendency of a loudspeaker to concentrate the sound in a narrow path instead of spreading it. 31. Bel 32. Bessel Alignment 33. Bessel crossover: 34. Bi-Amplification 35. Bi-amplify-The use of two amplifiers, one for the lows, one for the highs in a speaker system. Could be built into the speaker design or accomplished with the use of external amplifiers and electronic crossovers. 36. Bipolar Transistor 37. Bi-wiring:The use of two pairs of speaker wire from the same amplifier to separate bass and treble inputs on the speaker. 38. BL:-(measured in Tesla meters) The product of a speaker driver's gap flux density and the length of the voice coil conductor in the gap. 39. Blank Skip 40. BNC-A type of high precision connection often used in instrumentation and sometimes in digital audio. BNC connectors sometimes are used for digital connections such as from a CD Transport to the input of a DAC. 41. BNC-A type of connection often used in instrumentation and sometimes in digital audio. BNC connectors sometimes are used for digital connections such as from a CD Transport to the input of a DAC. 42. Boomy: 43. Boomy: 44. Boost-To raise the level of a signal. The opposite of cut. (e.g., We used my equalizer to boost the highs going to my tweeters.) 45. Boost:To raise the level of a signal. The opposite of cut. (e.g., We used my equalizer to boost the highs going to my tweeters.) 46. Box:Another, and common name for a standard speaker enclosure. There are many variations in type, which are basically compromises between size, power handling, cost, frequency response, and many other considerations. Bridge Mounted (2 & 3-way speakers) 47. Bridged 48. Bridged 49. Bridged Power:Bridging an amplifier, combines the power output of two channels into one channel. Bridging allows the amplifier to drive one speaker with more power than the amp could produce for two speakers. Because of this high power output, bridging is the best way to drive a single subwoofer. If the amp is bridgeable, the owner's manual will have directions that tell you how. Usually, an amp is bridged by connecting the speaker leads to the positive (+) terminal from one channel and the negative (-) terminal from the other channel. However, be sure to consult your owner's manual before attempting to bridge your amp!Also, keep in mind that most amplifiers need to see a 4-ohm load when bridged to mono operation. When bridging an amplifier, use one 4-ohm speaker or, if you prefer multiple woofers, connect two 8-ohm speakers in parallel. Again, consult your manual before operating your amp in bridged mode. 50. Bridging 51. Bright-Listening term. Usually refers to too much upper frequency energy. 52. BTL 53. BTM:Best Tuning Memory. A feature in which the tuner selects radio stations by signal strength, and assigns them to presets in numerical order, according to their frequency value. 54. Built-in Crossovers:-Frequently used to limit the high-frequencies reaching a subwoofer, a low-pass filter crossover allows only frequencies below the crossover point to be amplified. A high-pass crossover allows only frequencies above the crossover point to be amplified — used to keep destructive low bass away from small speakers, so they can played safely. Crossovers may be variable or selectable. Continuously Variable means the crossover circuit can be adjusted to any frequency between the listed end points. Selectable means that any of several preset crossover points can be chosen to accomodate variuous driver (speaker) designs. 55. Bullet Horn (tweeter) 56. Bumped 57. Bumped & Vented 58. Buss or Bus-A signal-carrying conductor or electrical pathway designed to carry multiple signals. A mixing console auxiliary bus may carry signals derived from several channels on that console. The term is sometimes used to refer to a power distribution circuit, or "mains". 59. Butterworth crossover:A type of crossover circuit utilizing low-pass filter design characterized by having a maximally flat magnitude response, i.e., no variation in the amplitude response in the domain of the passband. 60. Butterworth crossover-A type of crossover circuit design having a maximally flat magnitude response, i.e., no amplitude ripple in the passband. This circuit is based upon Butterworth functions, also know as Butterworth polynomials. 61. Butyl |
