[. . . ] ON OFF Power Connection Connect the power cord to an AC outlet only after making all other connections to the subwoofer. Under such circumstances the subwoofer may work better away from the corner. Experiment to find the best position in your room. HELPFUL HINT: A particularly useful experiment is to place the subwoofer right at the prime listening position (move your couch or chair out of the way and put the sub in its place). Then play something with good bass content (preferably music), and walk around the room, listening to the subwoofer's response. When you locate an area that has an ample amount of well defined bass, you've found a good potential place to locate the sub. Figure 5 Typical arrangement for a single subwoofer in a home theater. 2. Move to corner for more bass On the 212 SB you can use the level control on the rear panel to make this adjustment. If you decide not to use an SPL meter try to set all the speaker levels the same using the Test Tones. Of course, this will be much more difficult without the meter, especially for the subwoofer. Figure 6 (422 SB only) Front Panel Variable Level Control located behind the removable grille Recess and indicator for level adjustment Fixed Position Indicator LED Subwoofer Tuning Without an SPL Meter or Test Tones Start your listening with the subwoofer Crossover control set at around 100Hz or in the Bypass position if you're using a THX Certified processor or unit with a built-in crossover. Set the phase switch to normal, and the front panel variable level control (Figure 6) to the Preset position. Play some music that you know has good bass content, and turn the level control up until you just start to hear the subwoofer working. Now, from your normal listening position, determine whether the subwoofer is playing loudly enough and filling in the bass frequencies of the music evenly. If adjustment is necessary, start by changing the setting in the processor or with the level control if your processor lacks a subwoofer level adjustment. If the bass seems too ponderous, boomy, or heavy, no matter how you set the level, try moving the subwoofer away from the wall/corner. If the bass seems too thin, try moving the subwoofer closer to the wall/ corner. Small differences in positioning can make big differences in bass response. When you find a position that seems to work well, try switching the phase switch between its two settings, listening particularly to the transition from the subwoofer to the satellites. 1. Move away from wall for less bass System Set Up When setting up a complete home theater we strongly recommend that you use a Sound Pressure Level meter. Radio Shack® has a good one that is very affordably priced (approximately $40-50). To use this meter, turn on your system, put the Processor/Receiver in the Test Mode and set its main volume control to 0dB. Sit in the prime listening position, set the SPL meter to the 70dB scale, Slow Response, and C Weighting. Now, holding the meter pointed up and in front of you, let the system cycle its test tone from speaker to speaker and set every speaker to 75dB using the individual level settings in the Processor/Receiver. As tempting as it may be to set the subwoofer and/or surround speakers higher than 75dB, listen again after calibration and see if you can acclimate to these levels.
