3)The PT-7010A automatically sets the appropriate delays for each speaker so the sounds arrive at the primary listening position at the correct time.

4)Use the table at the right to record your speaker distance measurements.

Speaker Placement Tip - There is no substitute for well placed speakers, especially in pairs and especially in the main front (L, C, R) positions. If you can place the main speakers equidistant (at similar distances) from the primary listening position, you will enjoy the most balanced sound levels from most points in the room. The farther away or closer the left speaker is from the listener (when compared to the right speaker), the more delay one will have over the other. Sitting nearest the speaker with a high degree of delay does not sound natural. Read more about speaker placement tips in the “Speaker Placement Tips” section.

SPEAKERS Menu - CALIBRATION

The calibration procedure allows you to adjust the volume level of each speaker in turn until they are all equal. This will give you the best Home Theater performance. You should only do this calibration when you are sitting in your usual listening/viewing position.

Preliminary: Play a movie and adjust the volume for a comfortable listening level. The volume of the calibration test noise is linked to the setting of the main volume control, so if the test noise is too quiet, turn the main volume up a little and retry.

1)Use the OSD to navigate to the SPEAKER CALIBRATION menu.

2)Press the remote’s joystick down to turn on the noise generator. While the test signal is playing in each speaker,

its level can be adjusted using the joystick left/right buttons. Adjust each speaker in turn until they are all equal in volume.

The best results are obtained if you use a Sound Pressure Level (SPL) Meter. This is a hand held meter which will accurately measure and display the sound level. Adjust all of the speakers until they are playing within 1 dB of each other. Without a meter, you can still obtain good results with careful listening.

3)Repeat the procedure several times for each speaker until you are satisfied they are playing at the same level.

4)Press the joystick UP to return to the top of the menu, and then press joystick LEFT to exit. The calibration noise generator will turn off.
