Standard Bass Management
1.
In Standard Bass Management mode, you can de ne how you want the bass to be managed for each
Speaker with three options: Small, Large and «Large and Sub». Small will cut the Bass and redirect them
to the Subwoofer channel. Large will keep the Bass in the Speaker. «Large and Sub» will keep the Bass
in the Speaker and also redirect them to the Subwoofer channel. Speaker characteristics should be
clearly known to ensure you don't overload them with frequencies that they are not capable to
reproduce, especially in the case of small speakers limited in the low frequencies extension.
2.
Cut-o frequency of the Bass Management is adjusted per Speaker, either by entering the required
value or using the - / + buttons. The crossover Slope can be either 12 dB or 24 dB per octave, with
Linkwitz-Riley type. Frequencies and Slopes are the same for both the Speaker and the redirected Bass lters.
3.
When Speakers are set to Large, it is possible to redirect the LFE channel (Low Frequency Enhancement)
to them. Change this setting from None to a level between 0 to -20 dB, 0 dB being the highest.
