4.6.1

Bass Management Configuration 0

In some cases, the bass management filters are available in the decoder itself, so there is no need

to reproduce these filters. The output configuration shown in Figure 13 offers this possibility.

4.6.2

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.
