The settings can affect one another, so it may take a bit of fiddling to get everything dialed in correctly. When you set the size to small, the internal crossover circuitry in the processor routes the low bass frequencies away from the main speakers and to the subwoofer. It's too broad, and, in most cases, it begins rising at a certain frequency, called a turnover frequency (usually about 100 Hz), and raises the whole spectrum below that point. They already include equalization to compensate for the variations in the RadioShack meter's response. After you set the size, you can set the level. During this procedure, your processor will play a test tone through each speaker. Copyright O’Reilly Media, Inc., 2005. Checking Auto Calibration results; Selecting the Auto Calibration type (CAL TYPE) Level Settings. In 99.97265 percent of cases, you won't be able to achieve the proper calibration by using just your receiver's bass adjustment, so don't try it. It's a low-tech analog meter, but it's been a calibration staple in many pros' toolboxes for years. This is especially important with midpriced receivers. ‘Speaker level calibration will begin’ Now, the ‘Calibration process of home theater speaker’ begins and the loud test tones will be the output. I suggest you run AccuEQ to calibrate your system. Save my name, email, and website in this browser for the next time I comment. This is a relatively simple process that you can perform with a sound-pressure-level (SPL) meter and a test tone played through each speaker, one at a time. This material has been adapted from Home Theater Hacks by Brett McLaughlin, published by O’Reilly Media, Inc. These are all very fine instruments. This is assuming you use the little YPAO cal mike that came with the AVR. Keep working at it, and be sure to leave the meter in the same place. Figure 8-3. The three basic elements of audio calibration in home theater setup are: Speaker and subwoofer levels; Speaker and subwoofer distances ; Subwoofer phase; Whilst many modern AVRs provide automated setup routines, such as those by Audyssey, the results can be variable and in many cases better sound quality can be achieved by manually setting up your system. This will help make sure you keep the meter in one spot. Speaker levels being modified. It also is a good idea to set all treble and bass controls to 0 as well. If you hire a pro, you'll get the benefit of his years of experience and specialized tools. If you're using a graphic equalizer, it should have at least one-third-octave resolution. If you're comfortable with its placement, you can start fiddling. The really cool thing about the Rives disc is that it has tones that are Shack compensated. If yours does, it probably came with a specially calibrated microphone. First, the extended bandwidth limits the amplifiers that power the main speakers. It is critical for accurate sound that none of the speakers is too loud or soft with respect to the others. There are other meters, such as the B&K Precision 732A, the Brüel & Kjaer 2250 Light, and the Gold Line SPL120. You'll also note a distance setting in the speaker-setup menu. The receiver does not turn off even when the TV is turned off. The above procedure works fine for setting each channel's overall level. Let it get the money seat while you crawl around on the floor listening for the most natural bass sound. Don’t continue to change the master volume on your receiver or preamplifier because this will change the output level from the first speaker tested, skewing your setup. Turning on the receiver/preparing the remote control, Inserting batteries into the remote control, 6. The desired result, however, is the same. "Reference Level Calibration" is setting all speakers to the "Reference" level. To measure 75dB output, set the dial on the meter to 70 and then adjust the speaker volume until the little needle hits the +5 mark on the meter display. Usually, you'll save a bit of cash using the do-it-yourself approach. Performing Auto Calibration; 6. The specific calibration process differs depending upon the equipment you've chosen to incorporate. Keep these corrections in mind when you're calibrating your subwoofer. Then, you've got to make sure that all of the settings are correct and adjust your gear so that it reproduces your material the way it was intended. One of the simplest ways to find a good sub location is to swap places with it. The receiver is turned off automatically. In addition to the primary listening position, you should also be able to get good performance at the other seating locations, if you've done your homework during the design process. Hack #63 from Home Theater Hacks by Brett McLaughlin (O’Reilly Media). Proper calibration is the final step that can make your home theater perform its best. Your subwoofer is specifically designed to handle these lowest notes, and, chances are, if you picked a good one, it'll do a better job with low bass than your other speakers. There's more to getting the home theater of your dreams than piecing together a bunch of equipment. The chief environmental factor that can influence your home theater's performance is the room itself. Don’t move the meter during the tests. Once all speakers output the same level, you’ve got a well-calibrated home theater speaker setup. Standing up while taking sound levels results in an inaccurate reading, unless, of course, you prefer to stand through a three-hour showing of The Return of the King! The goal of calibrating the audio system in your home theater is to get a smooth, even frequency response at the primary listening position. You'll have peaks and dips in the low-frequency response that vary by frequency and location within the room. No sound or only a very low level of sound is heard from specific speakers. How to Calibrate Speakers with a Sound Level Meter. When you're done, check the frequency response again. The calibration routines will have set the levels for all the speakers, based on some internal reference. The home menu does not appear on the TV screen. In the end, you'll have to experiment with this setting until you find the best sound. I have a question though: the guys that sold me my equipment told me to set my front speakers to "large" and the subwoofer to "none". The bass-adjustment-response curve on your receiver doesn't have the correct shape to target just the problem frequencies. Required fields are marked *. You can—as with any or all steps in the home theater–building process—either do it yourself or hire a pro. This is where you'll select how many surround speakers you're using and whether you're using a subwoofer. To reduce the frequency nulls, you must relocate either your subwoofer, your walls, or yourself. Either way, the levels will be calibrated properly. The reason for this is twofold. The other reason to select small is that, while larger speakers may be able to play very low, they may still sound better, play louder, and have less distortion if you don't ask them to plumb the depths of the lowest octave or two. And then, connect the sub to the front speaker's output.This was also described in the sub's manual (a Rel Quake).Is this a good idea at all...? The downside to the hire-a-pro approach is, as usual, its effect on your bank balance. Dolby Digital or DTS multi-channel sound is not reproduced. Your email address will not be published. You also can recruit a “calibration buddy” to help you in lieu of a tripod. Set the meter to slow response and "C" weighting. It is critical for accurate sound that none of the speakers is too loud or soft with respect to the others. Reduce the level on the equalizer at the trouble frequencies until the response is as smooth as you can make it at your listening position. How to choose the right speakers for your room? Move it around a bit and watch the effect on the frequency-response curve. By.
