• If you have small Center and Surround speakers, direct the low frequencies from
those channels to the Left, Right, or Subwoofer outputs.
• If no subwoofer is available, redirect the LFE channel to the Left and Right channel
decoder outputs.
Bass Management
This option determines how low frequencies are directed in the monitor system. The
choices are listed in Table A‐1
Subwoofer Crossover
The setting for the Subwoofer Crossover frequency depends on the capability of the
speakers from which you are diverting low frequencies: 80 Hz, 100 Hz, or 120 Hz. If those
speakers are particularly small, choose the highest frequency, 120 Hz. This not only
produces better response from your system, but also protects small speakers from damage.
Recommonded crossover points are also commonly provided in the documentation from
speaker manufacturers.
LFE Monitor Mode
This system determines whether the unit monitors an LFE channel. The default is Auto;
this means that the unit handles the LFE exactly like a consumer decoder does. Other
options are: On, the system always plays back any existing LFE from the LFE output;
and
Off, the system never does.
