Adjusting the Speaker Levels (Test Tone)

The levels of the five satellite speakers have been preset at the factory at “0 db”. This means that if you were able to position all of the satellites the same distance from your normal listening position as recommended, the sound from all five satellites will sound equally loud at your normal listening position. This “equality” in the satellites will provide the most realistic surround sound experience. However if, because of the size or shape of your listening room, you are not able to position all of the satellites an equal distance from your listening position, the TEST TONE function will allow you to Increase or decrease the levels of the center and rear speakers to achieve the proper surround sound balance. Note: You cannot change the levels of the left front and right front speakers with the TEST TONE function.

After you have positioned the 5 satellite speakers in the listening room you can adjust the Center and Rear speaker levels with the Test Tone as follows:

Note that in order for the TEST TONE function to work, the system needs to be in stop mode AND the disc tray must be empty.

1.Turn on the system and your TV.

2.Sit in your normal listening position with the remote control. You will be using the following buttons on the remote control to make these adjustments:

3.Press the TEST TONE/MODE button on the remote. You will hear a “hissing” sound (pink noise) from the left front speaker for a few seconds. The hissing sound will move from speaker to speaker as follows: Left ￿ Center ￿ Right ￿ R Rear ￿ L Rear, etc. If necessary press the VOLUME ￿ button to increase the master volume level so you can hear the sound more clearly. Allow the sound to travel around the five satellites several times. If the sound level from all five satellites sounds approximately the same, no further adjustment is necessary. Press the TEST TONE/MODE button again to cancel the Test Tone function. It is not necessary for you to make any further adjustments.

4.If the sound level of the Center of Rear speakers is higher or lower than the Left front and Right front speakers you can increase of decrease the level of those speakers with the CH.LEVEL + or - buttons.

Wait until the “hissing” (pink noise) sound is coming from the speaker which needs to be adjusted, and then immediately press the CH.LEVEL + or - buttons to increase or decrease the level of that speaker. The range of adjustment is + or - 10 dB in 1 dB steps.

5.After you make the necessary adjustments allow the pink noise to circle the room a few more times to confirm that the level of all five satellites sounds the same at your normal listening position. Re-adjust if necessary.

6.When you are finished with the level adjustments press the TEST TONE/MODE button again to cancel the test tone function.
