Tip

The volume level is adjustable from –10 dB to +10 dB. (Below –10 dB, “–∞dB” is displayed.)

Adjusting the cut-off frequency for the subwoofer(s)

To match the characteristics of the connected subwoofer(s), you can cut out the unwanted high and middle frequency signals entering the subwoofer(s). By setting the cut-off frequency (see the diagram below), the subwoofer(s) will output only low frequency signals so you can get a clearer sound image.
