Front L/R

Select LARGE for full-range front speakers to deliver full frequency response to the front left and right outputs. Selecting SMALL activates a 12dB per octave highpass filter and automatically routes low fre- quency information to the subwoofer output. Choices of 40, 80 and 120 Hz are available for the -3dB point. The SMALL setting is recom- mended unless your speakers are capable of handling full audio signals, or are equipped with their own crossovers.
