Subwoofer Frequency Response

The low pass filter attenuates high frequencies at 24dB per octave. The values given are for the 6dB point.

Subwoofer Output

Use of the subwoofer output is specified here. Selecting YES, then pressing SELECT allows you to display and adjust the crossover frequency for the subwoofer output. All summing and filtering is per- formed in the digital domain. You can select three different crossover points (40, 80 or 120Hz) for the subwoofer. Although you can bypass the crossover (OFF) and run a full range output if your subwoofer has an internal crossover, it is generally best to use the crossover in the MC-1.

NO mutes the subwoofer output and disables the Subwoofer Level parameter. For any 5.1 channel input, selecting NO routes the LFE (.1 channel) to any front, side or rear speakers set to LARGE.
