The VOLUME pushbutton activates the various volume control functions Press the SYS CAL, (System Calibration) push-button to activate the internal test signal generator for surround channel level calibration The Re-EQ+TM pushbutton activates the REEQualization filter and Timbre Match, which compensates for the differences in room acoustics between the movie theater and a home theater room Press the SURR (SURROUND) push-button to temporarily activate the surround channel time delay adjusting process The LATE NIGHT push-button turns the volume compression circuit ON and OFF Press the CNTR (Center) DELAY push-button to temporarily activate the center channel time delay adjusting process 10 Delay Calibration for Center and Surround Channels Delay Calibration for Center and Surround Channels Delay and Level calibration procedures are made relative to the listening area. The ideal listening area is defined as facing directly toward and centered between the front speakers, and in line with the left and right surround speakers. NOTE: Refer to the Front Panel Drawing on the opposite page and Figures 1 & 2 on this page for the following steps. Center Speaker Delay If the center speaker is located closer to the listening area than the left and right front speakers, its sound will reach the listener before the sound from the left and right front speakers. This difference in sound arrival times can degrade the listening perception of some sound tracks. The MSD4 allows you to adjust the center speaker time delay to correct for this difference so the sound from the center speaker reaches the listening area at the same time as sound from the front left and right speakers. NOTE: The MSD4 center delay can be adjusted from 0 to 5ms. Each millisecond delay corresponds approximately to 1 foot in distance. LEFT FRONT CENTER FRONT RIGHT FRONT lay to correspond to the difference in feet. Measure the distance from the listening area to the center speaker and then the front left and right speakers. If the center speaker is the same distance as the front speakers, no calibration is necessary since the default factory setting is 0ms. 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 corresponds to a listening room where the center speaker is the same distance from the listening area as the front left and right speakers.

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. [. . . ] If the signal source contains only a Dolby Pro Logic 16 How to Operate in a Stand Alone System cont Subwoofer Speaker (Off-On) Set the SUBWOOF switch to ON whenever a subwoofer is used in the system. In this mode, the LFE (Low Frequency Effects) are always sent to the subwoofer. The subwoofer also receives from any channel(s), that have their SPEAKER switches set to SMALL, low frequencies of 80Hz and lower. Set SUBWOOF switch to OFF when all SPEAKER switches are set to LARGE and no subwoofer is being used in the system. [. . . ]
