Using a Flex HT to Convert from 7.1 to a 3.1 System

This example illustrates how to take 7.1 Dolby or DTS channels and convert them into 3.1 without losing any rear or surround content. We attenuate the surround and rear channels by 3 dB, and then mix them into the front left and right main channels. For the bass management channel we extract the low frequencies from the left, right and center channels and the full bandwidth of the LFE channel, then mix it into the single subwoofer out.
