Configuring a Monitor System Setting Delay Values
A.2.1 Calculating Delay Values
Center Delay
L minus C (L – C) equals the Center delay setting in milliseconds.
For example, if C is 2 feet less than L or R, set Center delay to 2 ms. If C is three feet more
than L or R, set Center delay to –3 ms. If C = L = R, set Center delay to 0 ms.
Surround Delay
C minus S (C – S), the shorter of the two surround speaker distances, equals the surround
delay setting in ms.
Calculating Pro Logic Delay
Pro Logic delay calculation includes an additional factor. C minus S plus 15 (C – S + 15)
equals the Pro Logic setting in ms.
A.2.2 Entering Delay Values
Entering Delays in DolbyRemote 570
Use the dials to enter the delay values into the Delay fields shown in Figure A‐6. You can
also type in the fields.
Figure A-6 Speaker Delay Values
Note: If you set a negative Center delay value, the DP570 actually sets Center delay to 0
ms and adds corresponding positive delay time to the Left, Right, and Surround
outputs.
