The main point of these tones is to find the major peaks and nulls at low frequencies, and any inexpensive meter is fine for that, calibrated or not. More to the point, low frequencies are usually accurate enough even with inexpensive microphones. Subwoofer Test | 20Hz, 30Hz, 40Hz, 50Hz and 60Hz Tonesįirst, meter calibration offsets are not that useful because all Radio Shack meters are not the same. Some test CDs "calibrate" the level of each tone to match the known inaccuracies of the Radio Shack SPL meter, but we didn't do that for two reasons. Yes, it will take the better part of an hour to run these tests, but when you're done you'll know your room's true low frequency response. Simply place the meter where your ears are when seated in the listening position, play the CD, and write down each number displayed by the meter.Įach tone is ten seconds long, which gives you enough time to switch the meter range when needed. We also created a blank sheet of logarithmic graph paper you can print to plot the results. Therefore, we supply only low frequency sine waves, in 1 Hz increments, with a track organization that's easy to understand. Our intent is not to duplicate all of the features of commercial test CDs.

Our Room Measuring Primer explains how to use room measuring software. But they will give you an accurate assessment of the low frequency response of your loudspeakers in your room. These tones do not identify modal ringing or other time-based errors which are just as important. Check out our Privacy Policy.Note that these tones measure raw low frequency response only, and are meant for use only when it's not practical to connect a computer to your audio system.

Once the amp and source unit are level matched, you will want to make certain you are not overdriving your speakers. If you are going to use features like bass boost, SHOCwave or EQ settings, it may be necessary to readjust the gain to a lower setting to compensate for increased output at those frequencies. All level matching circuitry in the KX amplifiers is at the beginning of the signal chain. These test tones are sine waves meant to provide a consistent signal for the KX amplifier to reference. The engineers at KICKER have taken the guesswork, and hassle, out of matching the output voltage of your source unit to the amplifier with the Gain Matching feature. In any audio system, the goal is to reach maximum input and output levels without distortion or clipping. Next, slowly turn clockwise the gain on the amplifier up until you see the Gain LED light up or hear audible distortion, then turn it down a little. It matches the output of the source unit to the input level of the amplifier and features Gain Matching to prevent clipping the input. IE -5db gain setting track needs to use -5db Key sweep tone. Once you have chosen the correct Gain track for you gain setting please make sure you use the matching Sweep track to ensure correct KEY operation. With this set up you can get some clipping from the amplifier. With this set up you can get some occasional clipping from the amplifier. These test tones are sine waves meant to provide a consistent signal for the KEY The different recording levels are designed to give you the perfect gain match for your application. Drenis, it would be easier for us if you threw up a pic of the room, list the gear, for us to help you.If you want to visit a local KICKER dealer in your area, we recommend calling ahead to confirm store hours and availability. I'm not goofing at all here, how important is what your planning to do and what does it exactly do to your sound. A so called science type proudly says FTGV Posts: 3, Wow this is great. What does the population recommend? I'm looking for something that has tones from 20hzhz, but steady tones or sine waves I'm becomming frustrated with still trying to get the right sound out of my setup and I've had my setup for 3 months now Post edited by Drenis on November BlueFox Posts: 13, November edited November CoolJazz Posts: Here's a pretty good one.Įven includes a set of tracks for the RS meter. Now, I've been doing a lot of reading on test CD's with sine wave tones and different test tones for settings subs and calibrating. Since I have a 2-channel setup, I put it here.
