Audio Adjustment <Network>

Adjusting the Filter

First, determine the approximate band to be used, taking into consideration the reproduced frequency band and the characteristics of the connected speaker.

1.Open the cover of the remote controller in the Network Menu (refer to page 5).

This switches to Network Menu Setting Screen.

2.Press the FUNCTION button 1.

The display switches to Filter Adjustment Screen, allowing filter adjustments.

3.Press FUNCTION button 6 and select left (Left) or right (Right) channel (only for LR/IND mode).

Each press the FUNCTION button 6 switches left and right channel.

4.Press FUNCTION buttons 1 or 2 and select the filter to be adjusted.

Press the button to switch the band to be adjusted and high pass filter/low pass filter.

5.Press the 2/3 buttons to set up

the cut-off frequency of the selected filter (crossover frequency).

Holding down these buttons continues their operations.

6.Set up the cut-off frequencies of each filter for all the bands.

Repeat steps 4 and 5 to adjust each filter so that the band used and crossover frequency are appropriately located.

Important points in adjusting cut-off frequencies

•If the subwoofer is installed in the rear tray, setting a high cut-off frequency of L.P.F. of the subwoofer separates the bass and gives the listener the feeling that the bass is coming from behind. The L.P.F. of the subwoofer is recommended to be set at 100 Hz or below.

•Speakers used for mid and high-ranges are generally constructed to handle a limited level of input compared to low range speakers. If the cut-off frequency of H.P.F. is set lower than necessary, strong bass signals can reach the speaker and may damage it.

Important points in adjusting the level

•The low band, because of its sound frequency characteristics, incorporates the basic frequencies of many musical instruments. It is recommended that the level adjustment of the low band be made first, and then the level adjustment of the mid, high, and subwoofer be made in that order.
