OPERATION Power On Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver. Initially set the subwoofer’s Level Control M to the “O” position. Turn on your sub by pressing the power button 8 on the rear panel. Turn on your entire audio system and start a CD or movie soundtrack at a moderate level. Adjust Gain Turn your subwoofer’s Level Control M up to the “5” position (half way). If no sound emanates from the subwoofer, check the AC-line cord and input cables.
BASS OPTIMIZATION SYSTEM™ Infinity’s Bass Optimization System is a simple-to-use, yet sophisticated, low-frequency calibration system. Each Interlude subwoofer contains a parametric equalizer that you can adjust following the directions below. By following these instructions, you can improve the sound of your system. The Bass Optimization System Goal It is a fact of audio that what we hear at low frequencies is determined as much or more by the listening room than by the loudspeaker itself.
MAINTENANCE AND SERVICE plays the tones from the test CD and records the relative output level of each test tone, using the sound-level meter, on the provided measurement template. After all the tones are complete, the template contains a response curve for the frequencies below 100Hz.The user simply notes the frequency of the largest bass peak, calculates the correct amount of attenuation, and uses the “Q-Finder”to determine the width of the curve.
