Chapter Two : Setting Up PowerTouch

SP Level

In this step you will use your ears to balance the volume level of all the system’s speakers except the subwoofer for your room and listening position. (To set the subwoofer level, see “Setting the Subwoofer Level” on this page.) When all the speakers are set at the same volume level, your system will create a more realistic, spacious surround sound environment.

It is recommended to use a SPL meter to adjust the speaker levels accurately. (See “To obtain accurate output levels” on this page)

When setting the speaker levels, be careful against the high-level test tone that is produced.

1.Eliminate as many external noise sources as possible.

2.Sit in the place where you and your guests are most likely to sit while watching movies or listening to music.

3.If you are not already there, touch on the Setup Surround menu to open the Speaker Level menu:

4.Touch until the Test Tone display reads “Manu”.

5.Test noise will play from the front left speaker. Care- fully listen to the volume level of the noise.

6.Touch or to select the next speaker.

7.Carefully listen to the volume level of the test noise. If the noise is a different volume than the noise from the

front left speaker, use or to adjust the vol- ume so that the volume matches the volume from the front left speaker.

(Do not be concerned with the volume number readout on the Level display—this is for reference purposes only. Use your ears to determine if the two speakers are playing at the same volume).

8.Repeat steps 6 and 7 until all the system’s speakers (except the subwoofer) play at the same volume.

9.To confirm the volume levels, touch until the Test Tone display reads “Auto”. The test noise will automati- cally cycle between all of the speakers. Fine-tune the chan- nel levels as necessary.

10.When all the channels sound like they’re the same vol- ume, you’ve balanced your system.

11.To turn off the test noise, touch until the Test Tone display reads “Off”.

Setting the Subwoofer Level: Because of the way hu- mans hear, the test noise the Speaker Level menu sends through the subwoofer will not sound as loud as it re- ally is. (The Speaker Level menu subwoofer test noise is designed to be used with a sound pressure level meter for balancing.)

Because of this, you cannot use that test noise to prop- erly calibrate the level of your subwoofer by ear. To set the subwoofer level, listen to familiar music or films that have strong bass content and adjust the subwoofer level until it sounds balanced with the rest of the speak- ers.

12.Touch to move to the next speaker setting or touch

to return to the Setup Surround menu.

To obtain accurate output levels

To obtain accurate output levels, it is recommended to use a handheld Sound Pressure Level (SPL) meter. Readings should be taken from your actual listening position and adjust the level of each speaker to 75 dB SPL (C-weighted/ slow meter mode).

Bass Peak Level

In this step, you set the maximum volume of the bass sound

 

so that the speaker sounds are not distorted even when

 

 

excessively-large bass signal is input. When playback is

 

performed hereafter, the bass sound is regulated automatically
