The following information gives detailed instructions on the installation and operation of the SMART SR 130 processor. [. . . ] DTS: The DTS digital decoder is supplied with a test disc titled "DTS 6-track Setup Disc. " This disc is a convenient item for setting the SR 130 threshold levels. The test disc has 50 tracks with different test signals for the various channels. One test is "Pink Noise @ Reference Level (85 dB SPL). " The Left, Center and Right channels have different tracks for this test: Track #37 -- Left Pink Noise @ Reference Level (85 dB SPL) Track #39 -- Center Pink Noise @ Reference Level (85 dB SPL) Track #41 -- Right Pink Noise @ Reference Level (85 dB SPL) Put the test disc in the DTS and adjust the rotary dials for track #37. This is the Left channel pink noise test. Make sure that the engage light on the front of the SR 130 is on, indicating that the SR 130 is "active. " If not, then press the Engage button to activate the SR 130 (the light on the Engage button will illuminate). With the Pink Noise playing, adjust the MAIN threshold control until the red LED just above the pot illuminates. Turn the rotary dials on the DTS for both Center and Right Pink Noise (see above). Make certain that the LED above the threshold pot illuminates while these channels are playing Pink Noise. Make any minor adjustment to the MAIN threshold pot so that all three tests illuminate the red LED Adjusting Subwoofer threshold level: Set the rotary dials on the DTS to track #42. This is Sub-Bass Pink Noise @ Reference Level (85 dB SPL). With the Pink Noise playing, adjust the SUB threshold control until the red LED just above the pot illuminates. Set the system so that 85 dB SPL is measured in the auditorium while the Afterburner is DISENGAGED. Engage the Afterburner, and adjust the MAIN threshold level so that the red LED just about the pot just comeson. Confirm that the LED stays on when pink noise is played through Center and Right channels also. Play the pink noise through the subwoofer channel at 85 dB SPL in the auditorium, again engage the Afterburner and set the SUB threshold level so that the red LED just above the pot just stays on. If no calibration sound material is available, then setting the threshold levels for other digital decoders will require playing a digital print and setting the threshold levels by ear. Wait for a sound passage that has some strong dialog. Set the MAIN threshold level so that the red LED just above the pot blinks during these passages. Verify that during loud action scenes the red LED illuminates. For the SUB threshold adjustment, wait for a sound passage with a strong amount of subwoofer material. Adjust the SUB threshold level so that the red LED above the pot just illuminates. Using the Afterburner Breakout board: When using the Afterburner AFTER a processor to compress optical and digital soundtracks, it is possible to set the thresholds using either a digital OR optical Pink Noise track, and then following the instructions in the Other Digital Decoders section above. [. . . ] Plug Afterburner power cord into rack power strip. Plug digital player's power cord into rack power strip. Follow the instructions in the Afterburner 660 section of this manual for calibrating the Afterburner system (SECTION 2: INSTALLATION). Important Note: When connected to the Plug 'N Play, the SIGNAL cable (JM-21) exits the connector upwards, and the CONTROL cable (BS-22) exits downward. (see photo on opposite page) DTS-6D: Use two DB25 cables. [. . . ]
