7-Channel Multi-Amplifier System

To provide reinforcement for the ultra-low frequencies, inaddition to the Left/Right 2-channel amplifier used to reproduce mid-to-

high-range frequencies, this system incorporates a second L/R

2-channel amplifier just for reproduction of ultra-low frequencies

-- making the front speakers, in effect, a 4-channel amplifier system. Therefore, this has a total of 7-channel amplifiers inthe Multi Amplifire System (4-channel amplifiers in the front speakers + a L/R 2-channel amplifire in the surround speakers + a 1- channel amplifier in the center speaker). By utilizing discrete amplifiers for mid to-high-frequencies and low frequencies, high- quality sonic reproduction that is virtually free from distortion can

be realized. This Multi Amplifier System, which utilizes independent circuitry

for the different frequency ranges, enables superb sonic

reproduction free from distortion.

Built-in Subwoofer System
