Bass Management Configuration 1
Configuration 1, shown in Figure 14, assumes that all five speakers are not full range and that all of
the bass information will be redirected to and reproduced by a single subwoofer. This configuration
is intended for use with 5 satellite speakers.
To prevent signal overload, the five main channels are attenuated by 15 dB, while the LFE channel
is attenuated by 5dB to maintain the proper mixing ratio.
