Delay between speakers
Volume setting amongst speakers
Delay settings allow you to adjust the virtual space between front and rear speakers. This means
you can reproduce the sound space of a movie in your home.
If the surround speakers or the central speaker cannot be installed at the same distance from the
listening position as the front speakers, change the delay to obtain a better surround effect.
• If the distance (D2) from the listening position to the central speaker or the distance (D3) from the
listening position to the surround speakers is greater than or equal to the distance (D1) from the
listening position to the front speakers, no adjustments are required. Otherwise, adjust the settings
according to the chart below:
When listening to the test signal, adjust the volume of the central, surround (LH), surround (RH)
speakers and the sub-woofer so that their volume is equal to that of the front speakers.
