12 Audio Adjustments

Slope adjustment

!If you set a small absolute value for the slope (for a gentle slope), interference be- tween adjacent speaker units can easily re- sult in degraded frequency response.

!If you set a large absolute value for the slope (for a steep slope), continuity of sound between speaker units is degraded, and sounds appear to be separated.

!If you set the slope to 0 dB/oct. (Pass), the audio signal bypasses the filter, so the filter does not have an effect.

Phase adjustment

When the cross-over point value for filters on both sides is set to –12 dB/oct., the phase is reversed 180 degrees at the filter cut-off fre- quency. In this case, reversing the phase as- sures improved sound continuity.

Muting the speaker unit (filter)

You can mute each speaker unit (filter). When a speaker unit (filter) is muted, no sound is outputted from that speaker.

!If you mute the selected speaker unit (fil- ter), MUTE blinks and no adjustments are possible.

!Even if any speaker unit (filter) is muted, you can adjust the parameters for other speaker units (filters).

1Use MULTI-CONTROL to select NW 1. NW 1 appears in the display.

2Push MULTI-CONTROL left or right to select the speaker unit (filter) to be ad- justed.

Each time MULTI-CONTROL is pushed left or right, the speaker unit (filter) is selected in the following order:

Low LPF (low-range speaker LPF)—Mid HPF (middle-range speaker HPF)—Mid LPF (mid- dle-range speaker LPF)—HighHPF (high-range speaker HPF)

3Push and hold MULTI-CONTROL down to mute the selected speaker unit (filter).

MUTE blinks in the display.

# To cancel the muting, push MULTI-CONTROL up.

3Turn MULTI-CONTROL to select NW 2. NW 2 appears in the display.

4Push MULTI-CONTROL left or right to select the cut-off frequency (crossover fre- quency) of the selected speaker unit (fil- ter).

Each time MULTI-CONTROL is pushed left or right, cut-off frequencies (crossover frequen- cies) are selected in the following order:
