[. . . ] If the center speaker is closer than the front speakers you should adjust the delay to correspond to the difference in feet. Press the CNTR/DELAY push-button to start delay calibration procedure. Adjust the VOLUME control until the DELAY/VOLUME display reads a number equivalent to how many feet closer the center speaker is to the listening area. Press the CNTR/DELAY push-button a second time to exit the delay procedure. Surround Speaker Delay If the surround speakers are located closer to the listening area than the front speakers, their sound will reach the listener before the sound from the front speakers. This difference in sound arrival times can degrade the listening perception of some sound tracks. The MSD4 allows you to adjust the surround speaker time delay to correct for this difference so the sound from the surround speakers reaches the listening area at the same time as sound from the front left and right speakers. NOTE: The MSD4 surround delay can be adjusted from 0 to 15ms. Each millisecond delay corresponds approximately to 1 foot in distance.

This would correspond to a typical listening room where the surround speakers are 5 feet closer to the listening area than the front speakers. If your surround speakers are in a different location, adjust the delay to correspond to their distances from the listening area relative to the front speakers. Measure the distance from the listening area to the surround speakers, and then to the front left and right speakers. If the surround speakers are the same distance as the front speakers, the calibration delay should be set to 0ms. If the surround speakers are closer than the front speakers you should adjust the delay to correspond to the difference in feet. Press the SURR/DELAY push-button to start delay calibration procedure. Adjust the VOLUME control until the DELAY/VOLUME display reads a number that is the same as the number of feet measured in Step 1. Press the SURR/DELAY push-button a second time to exit the delay procedure. EXAMPLE: If your center speaker is 2 feet closer to the listening area than the front speakers, set the center delay to 2. If your surround speakers are 4 feet closer to the listening area than the front speakers, set the surround delay to 4. NOTE: The following table may be used to record your Delay Calibration Settings. Delay Calibration Center Channel Surround Channels Default Setting 0 5 New Setting Selecting inputs with the Remote Control results in the MSD4 input selection automatically tracking with the Control Center input.
