Low-Pass Filter for the LFE Channel

This setting is not set automatically by the Automatic Speaker Setup function (see page 40).

With this setting, you can specify the cutoff frequency of the LFE channel’s low-pass filter (LPF), which can be used to filter out unwanted hum. The LPF only applies to sources that use the LFE channel.

*If you are using THX-certified speakers, select 80 Hz (THX).
