1. How do I arrange my speakers or room treatment? The extent to which the room should be handled is up to the individual. The point is to make the room frequency response and the speaker position reach the ideal position so that MultEQ XT can have a good start. Start point to measure. But this doesn't necessarily require you to do a lot of processing like low frequency traps. There are a few things to note: a. If your main channel speaker is placed far away from the viewing position, you may need to tweet the speaker a little. A rule of thumb is to imagine that the center of your high-pitched vowels emits an 80- or 90-degree cone-shaped sound field with a cone-shaped sound field covering your entire viewing position. Each horn covers a different diffusion range, and sometimes you may get better or worse results with different off-axis effects, at least a good start. b. Just like a billiard ball, the treble unit points to the side wall to reflect the straight line to your ear. If the reflection point on the side wall is a hard surface, you can hang a picture or cloth to disturb the reflection surface. This allows you to listen. To more direct sounds, and not to make the sound field turbid, let the speaker TOE IN have some effect! c. If the center channel is placed one inch or more below your ear, please raise the center channel and align the tweeter to you. This will make the dialogue clearer. Audyssey is more able to equalize. Get good results. d. If you place the subwoofer in the corner, try moving the subwoofer at least a few inches from each wall. If you place the position in the middle of the room, try to leave a few inches before leaving and try to stay away from the side wall about 1/3 of the room width. In this way, the heavy bass can be avoided because the standing wave relationship is cancelled at the time of setting. e. If your audiovisual location is close to the back wall, try to sit in front of it. Sitting too close to the wall will make your bass gain too much, so no EQ can correct your backwall reflection. Home Theater Network Shopping Guide 2. Do I need a tripod to perform MultEQ XT testing? Yes, no exceptions! Placing the microphone on the seat not only changes the distance of the horn, but also affects the correctness of Audyssey's EQ correction. Holding the microphone with your hand can produce noise (breathing or moving). Because the handheld microphone destroys the low-frequency EQ correction, it usually causes confusion because your body is behind the microphone. The only way to correctly correct the sound field is to fix the microphone on the tripod, and the photographic equipment line should be able to find a tripod with a few hundred dollars. 3. Should I place a microphone to perform the MultEQ XT test? Once the microphone is mounted on the stand, the height of the microphone should be raised slightly above the chair cushion to prevent the back from affecting the measurement. Ideally, the microphone should be placed on you. Near the ear, if this position is too close to the back wall, you should move the microphone forward at least 12~18 inches. This is the first position to execute the MultEQ XT. The second measurement position should be at least three inches to the right of your first position, and the microphone height should be slightly higher than the back of the chair. The third position is the fourth to eighth measurement position at your left front three miles. It is entirely up to you to arrange your seat on site. The fourth to sixth positions are as close as possible to the mirror position of the first to third positions but deeper into the center of the room three miles. This will give MultEQ XT a clearer idea of ​​how your bass will reflect from the walls around your room and get a more balanced bass response. 4. Should I stay in the room when measuring MultEQ XT? MultEQ XT will measure and balance the room frequency response. If you are in the room and you are not in the same position every time you measure, your presence will affect The sound reacts. Ideally, you set up the microphone, walk out of the room and use the remote control to measure the value, then return to the room and change the microphone position to repeat the above action. 5. ONKYO 705 What is the Audyssey adjustment curve used above? Audyssey products offer three adjustment curves: Flat, Front, and Audyssey. The Front curve is not available on the Onkyo Surround Enlarger. The Audyssey curve is the preset curve for the 705 model. This line attenuates the high frequency portion, ensuring that you hear more direct sounds than the room wall reflections. The Flat curve does not use high band attenuation. Changing the listening mode to any THX mode on 705 also causes the MultEQ XT curve to become Flat. Therefore, the high frequency attenuation of the THX mode does not cover the attenuation of Audyssey. Unfortunately, it is not possible to manually select the adjustment curve on the ONKYO radio amplifier, unlike other brands. A small trick allows the amplifier to enter FLAT mode by first entering THX mode and then pressing the RE-EQ button to turn THX's attenuation off. But because this setting disappears as soon as the power is turned off. So if you want to use FLAT mode, you have to do it again! 6. Why does the Audyssey subwoofer measure a different distance from the actual distance? Audyssey measures the acoustic distance instead of the actual distance. This data can be affected by several factors: For example, the crossover control of the subwoofer (translator: just a few hertz to the subwoofer processing) will produce a delay, thus changing the acoustic distance. Placing the subwoofer or microphone in the corner also changes the acoustic distance. The most important factor is the phase of the bass! The subwoofer distance setting value is similar to the variable phase control. Audyssey uses this value to ensure that the subwoofer matches the phase of other speakers. (That is, the subwoofer sound arrives at the listener's position at the same time as other horn sounds.) We do not recommend that you change this value! However, you can try to change the above factors and then re-measure it to see if the value is close to the actual distance! 7.Audyssey detected that my speakers are both large and full bands. Should I let it be like this? The Audyssey MultEQ XT on the ONKYO device has a well-known problem: even bookshelf speakers, as long as 60HZ or less The threshold has a certain sound pressure intensity, and the expansion machine detects the speaker as a large speaker! We recommend that unless your speaker has a sound pressure level of -3db below at least 35HZ, don't make it a large speaker, you should manually change it to small. 8. How do I set my speaker crossover point (a few HZ is responsible for the subwoofer)? The crossover point is a device that gradually shifts the sound from the speaker to the subwoofer, meaning that it needs a little space to make this The transfer is gradually taking place. A good rule of thumb is to look at your speaker's frequency response curve to see what his lowest operating frequency is, or which frequency point output tone drops to -3db, find this point and then add 20HZ to this value. As a subwoofer crossover point. The original text is as follows: A good guideline is to look up the frequency response of your speaker and find its lowest frequency (or the point where it drops off -3dB), then add about 20Hz to that to use as the crossover setting. That said, the Crossover's slope (ie how quickly it transitions) is pretty steep, so you might be able to get away with adding as little as 10Hz to your speaker's lowest reproduceable frequency. Start with 20, then tweak to preference to get the best transition. Should I change the speaker distance measured by Audyssey? Audyssey seems to be able to detect that the speaker distance is quite close to the actual distance, but some people still think that this is not the best setting for the middle of the speaker. You can use Digital Video Essentials to test a series of test tones in the disc (these test sound fields are all in the center of the speaker), change the set distance by about half a mile at a time and slowly feel the sound field gathers in the center (meaning that it is set in this way) Make sure the speaker phase is correct). If the sound becomes more scattered or difficult to focus, it means that the speaker is not in phase with the other speakers after changing the distance setting. While Audyssey does seem to properly detect speaker distances close to their actual physical distances, some have found that this is not the best setting for between-speaker imaging. The calibration disc has a series of test tones that are noted equally between channels. Tones, you can tweak speaker distance a half-foot up and down to listen for the setting that makes the sound "hang" in space between the speakers (which means it is in phase at that setting). If the sound becomes more diffuse or Harder to pinpoint, it is because changing the setting is putting it out of phase with the other speaker. To change the speaker distance setting, face the front wall, follow the steps below: a. Play in the front left channel and the center channel Test the sound at a specific frequency, then slowly change the set value and move the center channel back and forth to see if it is at a certain distance setting, so that you feel the sound is more focused in the middle of the two speakers! Then repeat this action in the front right channel and the center channel, and select a setting that makes the two channels sound the best as the center channel distance setting. b. Play the test audio between the right front channel and the right surround channel, then adjust the right surround speaker distance up and down to find the best position of the side wall speaker distance, because the surround channel position is usually higher than the main channel speaker, maybe not Find a perfect setting, but you should be able to find a better sound field position from the side! c. Repeat the action of b in the left surround. If you only have the 5.1 configuration, then you are done here. d.For 6.1/7.1 setups, put your receiver into DPL-IIx Movie mode and play the tone between the right surround and the rear surround (since DVE only has 6.1 tones), or change DVE to the DTS track and use DTS-ES Matrix mode, then bump right rear surround distance up and down slightly until you hear solid placement of the sound between the two. Then repeat using the tone between left surround and rear surround, changing the distance setting for the left rear surround. If you only Have 6.1, bump your rear up and down to listen for the setting that works best with both tones. 10. Why is the peak cutting setting of the subwoofer so low? Welcome to the China Home Theater Decoration Network The common mistake is to adjust the gain or volume of the subwoofer too high, so that the buzz and hum of the subwoofer are amplified. If Audyssey sets the subwoofer trim low, try lowering the gain or volume of the subwoofer and then measuring it again! Or you can check it once with SPL meter so you don't have to run it again without the Audyssey process. Ideally the subwoofer trim is as close as possible to 0, and your subwoofer gain is at its maximum 1/3! 11. Why are all my channel TRIM values ​​very low? Audyssey tries to make all the speakers in your amplifier's relative volume value 0, you hear the reference playback level reference playback level (that is, your speaker) At this time, the sound pressure is 105db, and the subwoofer sound pressure is 115db.) However, because of the different horn efficiency of each factory, these sound pressure levels will change due to factors such as the horn brand, room sound effects, and the like. If you don't care if 0 is the reference sound pressure or if you use absolute volume readings, then you can increase all channel values ​​to near zero if you like. However, because the maximum volume value of ONKYO 705 is determined by the maximum channel trim you set, if you set the highest channel trim +2, the maximum volume will be reduced from the relative volume +18 to +16. So you won't get extra output volume from the amplifier! Many people may notice that Audyssey sets the TRIM value about 2-3dB lower to reach the reference level at 0. You can use SPL meter to measure the sound pressure of each channel to 75db. 12. When Audyssey measured the cold air suddenly opened, the puppy called, or the voice sounded, do I have to re-measure it? The original meaning means that it is best to measure in a quiet environment, turn off the air, take the dog out, and then Start measuring! 13. What is Audyssey MultEQ XT doing? MultEQ XT reads hundreds of data to measure the frequency response characteristics of your room, computes the data and adds a reverse filter, which means it detects some If there is a peak in the frequency band, he will use reverse filtering to eliminate this peak. In the reverse direction, if a certain frequency band has a depression, he will perform an amplification action. This will allow your room to reach a flat frequency response curve! For the subwoofer, he hopes that you hear the first direct sound of the bass, not the sound that the bass reflects from the room! (It's what the average person calls a tight low frequency). That's why it's so important to detect where the microphone is placed! In addition, the MultEQ XT analyzes a large area and then inversely filters the numerical operations of each position to ensure that you can hear the same sound for each of your audiovisual positions. 14.Why can't I tweak the EQ settings that Audyssey comes up with? (for ONKYO 705) while the 705 offers a 7-band manual EQ, this is only as a middle and does not reflect what MultEQ XT uses to make its Adjustments, nor does it account for adjustments in the time domain that Audyssey makes. For each channel, Audyssey bases its equalization on hundreds of points along the frequency range and can potentially be making as many adjustments per channel. There is currently no way to alter Those settings or even represent them on-screen, even with the vastly more expensive MultEQ XT Pro that uses a standalone PC to do its calculations. 15. But if that's true, why does X brand let you change the EQ after Audyssey? Some receivers , notably the Denons, let you alter equalization after Audyssey runs. They do this by copying the resulting curve as best they can to the 7-band EQ, giving you a general notion of where the biggest problems lie. This lets you make coarse adjustments But also nega Tess all the fine adjustments that Audyssey makes, as well as the ideal equalization for all positions. 7 bands of equalization in no way represent the resolution with which Audyssey makes its adjustments. 16. I need to do Audyssey MultEQ XT for each source. Analysis? It only takes one time to do it. He measures the performance of the speaker instead of the source, so it can be done once. 17. If the measured low frequency crossover point is 80HZ and my speaker setting crossover point is higher than this value, will the sound in the middle disappear? The low frequency crossover point only affects the subwoofer output channel (the .1 It is not the overall sound The 705 defaults to the THX LFE cutoff of 80Hz and Audyssey doesn't adjust that setting. However, the LFE channel by its very nature is brickwall filtered during encoding at 120Hz. If you want to accurately reproduce the entire LFE channel , set LFE cutoff to 120Hz. However, few sound mixes have audio above 80Hz in the LFE channel, which is why THX recommends the 80Hz cutoff. Also, because the LFE channel receives a +10dB boost during decoding, the THX recommended 80Hz cutoff is There to reduce the chance of humming/noise above 80Hz from the LFE channel. Chances are that you will not notice a significant difference, if any, by changing LFE cutoff from its default of 80Hz, but doing so has no effect on the bass redirected From the other channels. 18. Although I am very careful to place the microphone and where Change the value setting if you don't like it! Our door must be considered for different brands to expand the horn, etc., a person accustomed to listening to clear sounds, listening to the neutral real voice may not like, although this is a more correct voice! And a person who is accustomed to rock and low frequency may feel that the low frequency is not enough after adjustment! We recommend that you change your voice, Audyssey's adjusted voice, give yourself a few days, listen to the music or movies you are used to listening to. (Perhaps the bass seems to be insufficient, but after listening to it, you find the bass notes. Change it clearly) then evaluate the advantages and disadvantages! If you are still not satisfied after a few days, of course you can change it! Reprinted from: http://&postcount=151 Â
