Using two power amplifiers to drive one loudspeaker. One amplifier typically drives the woofer, while the second drives the midrange and tweeter.
In loudspeakers that have the appropriate connections, bi-amping is the practice of using two power amplifiers to drive a single loudspeaker, one for the woofer and one for the mid/high frequency section. Normally, the internal passive crossovers are used so that the manufacturer's system design is left intact (assuming that the amplifiers gains are identical, and they are in phase). In large professional systems an external electronic crossover is often used, in which case it is essential to equalize the system afterwards, since the user is really designing the loudspeaker system from the ground up. See: Bi-Wiring.
In bi-amping, the woofer and tweeter of a speaker are driven by signals from separate amplifiers (or amp channels). This way, both low-frequency drivers (woofers) and high-frequency drivers (tweeters) receive dedicated amplification.
A process where two separate amplifiers are used to power separate drivers within the same speaker.
A separate amplification source is used to drive each speaker unit. A pair of speakers would require two separate stereo amplifiers with two lots of cable to each speaker.
Using one channel of an amplifier to drive each Ribbon and midbass so that a stereo pair of speakers requires 4 channels of amplification. Means that instead of driving a speaker full-range with a single channel of amplification, through a single set of speaker cables, you actually connect two sets of cables, with each set driven by a separate amplifier, or separate channels of a multi-channel amplifier. This way, low frequencies and high frequencies each receive dedicated amplifiers.
Bi-amping refers to the use of two separate amplifier channels connected directly to individual loudspeaker drivers optimized to reproduce a particular frequency range. For example, one amplifier channel would be connected directly to a tweeter for high frequency reproduction, another to a woofer for bass reproduction. Bi-amping requires an electronic crossover to divide the wide range audio signal from a preamplifier before that signal ever gets to the amplifiers. The advantages of traditional bi-amping are significant. Damping factor (a measure of the amplifier's ability to control the back-and-forth motion of the driver) increases, intermodulation distortion goes down, and effective amplifier power is increased dramatically.
Bi-amping refers to the use of two separate amplifier channels connected directly to individual loudspeaker drivers. Bi- amping requires (usually) an external active crossover to separate the frequencies before sending them to the respective amps.
Instead of driving a speaker full-range with a single channel of amplification through a single set of speaker cables, you actually connect two sets of cables, with each set carrying the signal from a separate amplifier (or amp channel). This way, both low-frequency drivers (woofers) and high-frequency drivers (tweeters) receive dedicated amplification.
In bi-amping, separate amplifiers (or amp channels) drive the woofer and tweeter of a speaker. This way, both low-frequency drivers (woofers) and high-frequency drivers (tweeters) receive dedicated amplification.
Bi-amping is the practice of connecting two audio amplifiers to a loudspeaker unit: one to power the bass driver (woofer) and the other to power the treble driver (tweeter). A single amplifier can usually power a woofer and a tweeter only through a crossover filter, which protects each driver from signals outside its frequency range. However, the crossover itself wastes power, so bi-amping is a way to avoid this problem.
