The Bijou is the first THX room equalizer to offer a full five channels of control (enough for any surround system) along with a one-sixth octave precision subwoofer equalizer. This level of control means your home theater will sound the best it possibly can; from the subtle clink of champagne glasses to the thunderous blast of a train crash. This is what a home theater is all about. With five channels of equalization, the Bijou allows every speaker in the home theater to be independently “voiced”. Even the often overlooked surround channels have 8 bands of their own stereo equalization control.
