ADJUSTMENTS BEFORE OPERATION
MAIN/CENTER/EFFECT SPEAKER LEVEL BALANCE ADJUSTMENT
This operation uses an internal test-tone generator for balancing the levels of the main, center and effect speakers.
1.Depress the TEST switch on the remote control so that “TEST DOLBY SUR.” appears on the display panel to enter test mode. A hiss-like calibration signal should be heard from the left main speaker, center speaker(s), right main speaker, right rear effect speaker and left rear effect speaker in turn (see diagram). Adjust the master VOLUME to a normal listening level.
* The state of test-tone output is shown by the display panel and the monitor screen. (On the monitor screen, it is shown by an image of audio listening room.) This is convenient for adjusting each speaker level.
| Left main | | Center | | | | | Right main |
| LEFT | | | | | | CENTER | | | | | RIGHT | |
| | | Left rear | | | | | | | | |
| | | | | | Right rear |
| | | | | | | | |
| | | LEFT | | | | | | RIGHT | |
| | | SURROUND | | | | | | SURROUND | | | |
2.Adjust the center and rear level by using the CENTER and REAR LEVEL +/– keys on the remote control so that the sound coming from the corresponding speaker seems to be at the same level as that from the main speakers when you are at a normal listening position. The REAR LEVEL +/– keys adjust the right rear level if pressed while the test-tone is output from the right rear effect speaker, and adjust the left rear level if pressed while the test-tone is output from the left rear effect speaker. If the REAR LEVEL + or – key is pressed while the test-tone is output from other than the right or left rear effect speaker, the key adjusts either the right or left rear level that has been adjusted last time.
*If there is insufficient volume from the effect speakers, you may decrease the main speaker volume level by setting the MAIN LEVEL switch on the rear panel to “–10 dB”, and adjust the center and rear level again. Volume controls on external power amplifiers may also be adjusted if necessary to achieve proper balance.
*Pressing the Parameter + or – key (only when the PARAMETER/SET MENU switch is set to the PARAMETER position) transfers the test-tone from the speaker that is currently outputting the test-tone to the right or left rear effect speaker. Pressing “+” transfers the test-tone to the right rear effect speaker, and “–” to the left rear effect speaker.
*Pressing and holding the Parameter Select ▼ or ▲ key (only when the PARAMETER/SET MENU switch is set to the PARAMETER position) fixes the test-tone on the speaker that is currently outputting the test-tone.
NOTE: If not using a center speaker, be sure to set the CENTER SP mode to the PHNTM (phantom) position. You will then hear the center channel test tone from the left and right main speakers.
