What is Biamping?

What is Biamping?

Biamping is separating a signal into 2 bands, high frequency and low frequency, and sending each band to a separate amplifier. One amp is used for the high frequencies, which are sent to the horn, and the other amp is used for the low frequencies, which are sent to the woofer. Since low frequencies require more power to reach the same volume as high frequencies, biamping allows for a greater balance in the sound. Biamping also results in more efficient amp and speaker operation, as well as greater headroom.

Biamping is commonly used in bass amps, where the signal from the preamp section of the bass amp is split and sent to two power amps built into the amplifier. The highs are then sent to the horn, while the lows are sent to the woofer.

Biamping is also commonly used in live sound systems, where the main outputs of the mixer are sent to a crossover and split into 2 or 3 (called "triamping") frequency bands before being routed to power amps.
