Adjustable parameters

C. SP : Adjusts the center speaker delay time. Delay time can be set between 0 ms and 5 ms.

When the distance between the listening point and the center speaker is close to the distance to the front speakers, set the delay time to 0 ms. Increase the delay time when the distance to the center speaker is shorter.

A 1ms increase/decrease of delay time is equivalent to a 30 cm change in distance.

R.SP : Adjusts the rear speaker delay time.

Delay time can be set between 0 ms and 15 ms. When the distance between the listening point and the rear speakers is close to the distance to the front speakers, set the delay time to 0 ms. Increase the delay time when the distance to the rear speakers is shorter.

A 1ms increase/decrease of delay time is equivalent to a 30 cm change in distance.

Speakers marked with a “ – – ” cannot be adjusted.

“CROSS OVER” has the same effect as setting with “SPEAKER SIZE”.
