<b>Hi, this is Obsessive Compulsive</b> <b>Audiofile and today I'm</b> <b>introducing you to Acoustica,</b> <b>the latest iteration of the free and</b> <b>powerful sound optimization tool, A1evo.</b> <b>Acoustica is not only acoustically the</b> <b>best version to date,</b> <b>but it's also easier to use</b> <b>than ever with full</b> <b>integration and automation.</b> <b>Whether you're a seasoned user or just</b> <b>getting started, this</b> <b>tutorial will help you unlock</b> <b>the full potential of your</b> <b>setup using A1evo Acoustica.</b> <b>So let's dive in and fire those subs up.</b>

<b>Alright, for the newcomers,</b> <b>first of all what is A1Evo?</b> <b>It's a free and easy to use and even</b> <b>easier with Acoustica.</b> <b>Advanced sound optimization</b> <b>tool for home cinema systems.</b> <b>When I say home cinema, it can optimize</b> <b>also stereo systems as</b> <b>long as there's a subwoofer.</b>

<b>So 2.1 is the bare minimum and it can go</b> <b>up to 16.4 full Dolby Atmos system.</b> <b>From zero to complete and great sounding</b> <b>system, it takes a</b> <b>couple of minutes to complete</b> <b>and you don't need any previous</b> <b>experience with A1Evo or any sort of</b> <b>digital room correction</b> <b>for that matter.</b> <b>It integrates with Room EQ Wizard, a</b> <b>fabulous free tool for</b> <b>digital room correction.</b>

<b>It can use your existing Audyssey</b> <b>measurements, whether they</b> <b>are taken with MultiQ-X or MultiEQ</b> <b>Editor app, or it can use</b> <b>your manual REW measurements.</b> <b>And for the enthusiast, it allows custom</b> <b>target curves as well as</b> <b>highly advanced customization</b> <b>options</b> <b>which a regular user needs in its</b> <b>standard settings, it</b> <b>will give you a near perfect</b> <b>sound.</b> <b>You can see in the last 48 hours since</b> <b>it's being beta tested,</b> <b>these are some of the comments</b> <b>from actual users.</b> <b>What you need to use A1Evo?</b> <b>You don't need the app,</b> <b>neither MultiEQ-X or the Editor app.</b> <b>Acoustica has its own</b> <b>communication interface.</b> <b>You need a compatible</b> <b>Denon or Marantz AV receiver.</b>

<b>No other brand will work with A1Evo.</b> <b>You need at least one subwoofer as I said</b> <b>before and the</b> <b>compatible models are exactly</b> <b>the ones listed here.</b> <b>If your AVR is compatible with the Editor</b> <b>app, then it's compatible with Acoustica.</b>

<b>If not, it's not.</b> <b>Also you need individual measurements for</b> <b>each of your speakers</b> <b>and subwoofers in your</b> <b>system.</b> <b>There's nothing extra you have to do and</b> <b>that's basically all you need.</b> <b>Now let me show you step</b> <b>by step how you use it.</b>

<b>There will be a link to this folder in</b> <b>the video description.</b> <b>This is where you download A1Evo Acoustica</b> <b>for your operating system.</b> <b>I use Windows so I</b> <b>will download this one.</b> <b>I will explain what</b> <b>the other files are for.</b> <b>But basically there's Linux, macOS for</b> <b>both Intel and M</b> <b>series and Windows versions.</b> <b>Unable to scan for</b> <b>viruses, download anyway.</b>

<b>Okay the zip file, you</b> <b>save it wherever you want.</b> <b>Let me make a new folder here.</b> <b>Let's say "look at</b> <b>video" and download it here.</b>

<b>Okay suspicious download.</b> <b>Because it's a Node.js program with lots</b> <b>of JavaScript and</b> <b>opening other files in the</b> <b>PC, it's very likely to get false</b> <b>positive for virus detections.</b> <b>You might need to turn off your Windows</b> <b>Defender virus protection</b> <b>to download it or download</b> <b>all of the folder.</b> <b>Then I think it will not</b> <b>give you these warnings.</b> <b>Okay it's downloaded.</b>

<b>Extract it here.</b> <b>And this is the tool.</b> <b>Just one file, nothing else.</b>

<b>And to show you that it's actually virus</b> <b>free, I'm gonna check it with VirusTotal.</b> <b>This is the best known virus program.</b> <b>Confirm uploads.</b> <b>As you see it doesn't</b> <b>have any wires in it.</b> <b>This website checks it with every single</b> <b>virus detection tool out there.</b> <b>And none of them have</b> <b>detected it positive.</b>

<b>Then you run it.</b> <b>Double click.</b> <b>Windows keeps still</b> <b>protecting for it but run anyway.</b>

<b>And there you go.</b> <b>This is the tool.</b> <b>It can discover your AVR in the network.</b>

<b>Option 1.</b> <b>Which we should do.</b> <b>Searching network for AVR receiver.</b> <b>It didn't find.</b> <b>It will normally find but my AVR has</b> <b>locked itself during the</b> <b>test today so I know it's</b> <b>IP address.</b> <b>You can find your AVR's IP address in its</b> <b>stack menu in the network settings.</b>

<b>In case it doesn't find your AVR, it's</b> <b>actually very capable.</b> <b>If it finds multiple AVR's you can select</b> <b>one and you can also</b> <b>manually enter the IP</b> <b>address.</b> <b>And once you enter it, it finds it and</b> <b>it's giving you its name</b> <b>just to confirm because</b> <b>there may be more than one.</b> <b>And you say yes.</b> <b>And done.</b> <b>You will see that here it's already now a</b> <b>receiver config.avr file.</b>

<b>It's a JSON file where it has read all of</b> <b>the settings and show you.</b> <b>This is the online JSON editor and if you</b> <b>put it here you will</b> <b>see that at the moment</b> <b>I turned off my utmost just to make the</b> <b>test quicker with just five speakers.</b> <b>It read my Marantz.</b> <b>AVR receiver is at the moment off.</b> <b>It's not even turned on and now I have</b> <b>all the speakers, amp-</b> <b>Assign, everything else</b> <b>that the optimizer needs.</b> <b>So it saves this file and</b> <b>you only have to do this once.</b>

<b>Next time I run it, if it finds this one</b> <b>in the folder, it's not</b> <b>gonna ask you to create</b> <b>one but you can recreate.</b> <b>As you see the menu has changed from</b> <b>generate to recreate.</b> <b>And after that if rew is installed on</b> <b>your PC, all we have to</b> <b>do is go come to option</b> <b>2 and start optimization.</b> <b>I didn't even open rew</b> <b>so it's opening it for me.</b> <b>It's gonna start rew and start this API</b> <b>server to lots of users</b> <b>before was having problems</b> <b>with forgetting</b> <b>starting the API server of REW.</b>

<b>Now this is taken care of.</b> <b>So here is REW and here is A1 Acoustica.</b> <b>It requires measurements in REW that</b> <b>match with this speaker</b> <b>profile of your system which</b> <b>means you have to have measurements for</b> <b>each of your speakers in REW.</b> <b>As long as you have that,</b> <b>it will start optimization.</b>

<b>You can use your manual rew measurements.</b> <b>For manual measurements, I won't go into</b> <b>the details of that in</b> <b>this video but you can</b> <b>watch next week's video where I have gone</b> <b>into full detail of</b> <b>how to use rew for manual</b> <b>speaker measurement.</b> <b>You will need obviously Atmos REW</b> <b>measurement sweeps which</b> <b>are linked here in the folder.</b> <b>Here you have for every 16 channels of</b> <b>Atmos sweeps which you can</b> <b>play with VLC media player.</b> <b>So you can use your upmost speakers also.</b>

<b>You can also measure</b> <b>your Atmos speakers.</b> <b>And for that you need VLC media player.</b> <b>You will see that here</b> <b>in the A1 Acoustica here.</b>

<b>This is the link to</b> <b>download latest rew beta.</b> <b>This is the link to</b> <b>download VLC media player.</b> <b>There is a Facebook group with over 2000</b> <b>members where you can ask questions.</b> <b>They are very helpful.</b> <b>You can ask under the</b> <b>video comments to me.</b> <b>Now, let me first open some measurements</b> <b>that I have for my system which are here.</b>

<b>I think this one.</b> <b>So once you have your measurements in</b> <b>rew, this is one way</b> <b>that I had a saved rew file</b> <b>with my measurements.</b> <b>I can start doing the optimization.</b> <b>Or let's say you have an Audyssey</b> <b>measurement taken by the</b> <b>Editor app from the past like</b> <b>this one.</b> <b>As you see you can use this button and</b> <b>all the measurements in</b> <b>that .ady file, 52 of them,</b>

<b>are now in REW and also</b> <b>saved here as rew and that.</b> <b>And you can start optimization with that.</b> <b>But obviously this is somebody else's .ady</b> <b>file just for my tests and</b> <b>the speaker configuration</b> <b>here.</b>

<b>As you can see he has a center speaker</b> <b>and from here I don't.</b> <b>Ask me why I'm not using a center speaker</b> <b>but eventually everybody will ditch their</b> <b>center speakers.</b> <b>Anyway, this guy also has two subs.</b> <b>I have only one.</b>

<b>So, this is another way.</b> <b>This can also optimize extract .mqx.</b> <b>But if you're doing your own measurements</b> <b>with REW then you don't need any of this.</b> <b>You just measure them.</b> <b>You just name them from the top.</b>

<b>The measurements at the top should be the</b> <b>central listening</b> <b>position measurements and</b> <b>there is no other restriction.</b> <b>You can just keep naming them as you wish</b> <b>as long as they contain</b> <b>FL, C, FR at the beginning</b> <b>which are the official names for the</b> <b>speakers and you can just optimize.</b> <b>Now let's go back to my measurements.</b> <b>As you see I'm switching to SPL &Phase tab</b> <b>because this runs faster</b> <b>and safer because here it</b> <b>has to draw a lot of graphics during the</b> <b>optimization process</b> <b>which is not efficient.</b>

<b>So try to keep rew in SPL&Phase tab.</b> <b>Now the options.</b> <b>I'm not going to go through</b> <b>the options at this stage.</b> <b>Let me just start optimization.</b> <b>It already determined crossover</b> <b>frequencies and speaker distances,</b> <b>optimal distances here</b> <b>and crossover frequencies here.</b> <b>Now it's creating</b> <b>filters for Audyssey Flat.</b>

<b>And it's finished.</b> <b>When it's finished it generates a .oca</b> <b>calibration file and you</b> <b>have to save it in where your</b> <b>acoustic file is.</b> <b>Also reports here.</b>

<b>And if you save it somewhere else you</b> <b>always have the option to</b> <b>enter the path to this calibration</b> <b>file.</b> <b>And then you can also save the log, this</b> <b>log here for future reference.</b> <b>Let's save it.</b> <b>This doesn't need to be in any particular</b> <b>folder but let's also save it there.</b> <b>Now let's see what is in the folder.</b> <b>There is A1 Acoustica of course.</b>

<b>There is the .oca calibration file.</b> <b>It's an other JSON file...By the</b> <b>way, if you wonder what it is.</b> <b>As you see very similar to the</b> <b>configuration file but</b> <b>this one has filters in it.</b> <b>And this one has distances and speaker</b> <b>volume levels and crossover frequencies.</b> <b>Also for subwoofer here.</b>

<b>And lpf, low pass filter for LFE channel.</b> <b>So this is the settings that you need to</b> <b>send to your AV</b> <b>receiver for optimized sound.</b> <b>Your program is still</b> <b>running here in parallel.</b> <b>So what you do now is go to 3 and</b> <b>transfer calibration.</b>

<b>It will check for every</b> <b>OCA file in the folder.</b> <b>There is only one at the moment.</b> <b>So just press enter and it will pick up</b> <b>the most recent OCA file.</b> <b>Again connecting to the AVR.</b>

<b>It's connected powering it on.</b> <b>I don't know if you could</b> <b>hear the relay clicking.</b> <b>And checking if my AVR has preset support</b> <b>unfortunately it does not.</b> <b>But here you can also select the preset</b> <b>that you want to send the calibration to.</b> <b>With multiple presets you can send two</b> <b>different calibrations.</b> <b>Also Acoustica sends one setting for</b> <b>Audyssey Flat which is the</b> <b>normal listening filters.</b>

<b>And one setting for different settings</b> <b>for Audyssey Reference.</b> <b>So even if you don't have presets you</b> <b>have two different calibrations.</b> <b>And Audyssey Reference calibration is for</b> <b>low volume listening.</b> <b>From low volume listening at night you</b> <b>can't always listen at reference levels.</b>

<b>And the naming is kind of confusing but</b> <b>Audyssey Flat is for reference level, your</b> <b>normal listening level.</b> <b>And Audyssey Reference is for low volume</b> <b>listening which should be</b> <b>around 12 to 25 dB lower</b> <b>than your usual level.</b> <b>And it's all finished.</b> <b>Done.</b>

<b>And when you start playing your system</b> <b>right now you will have</b> <b>a very different sound to</b> <b>what it was before the calibration.</b> <b>Feel free to test.</b> <b>That's basically it.</b>

<b>But now let me show you some options.</b> <b>And if you want to check your AV receiver</b> <b>now which you can do like this.</b> <b>There's a WEB UI.</b>

<b>As you see it's set my fronts small,</b> <b>subwoofer one and</b> <b>surround small and distances.</b> <b>Are all set according to the</b> <b>findings in the optimization.</b> <b>You can check here that for example front</b> <b>speaker distance is</b> <b>275 and here it's 275.</b> <b>By the way the distances are not going to</b> <b>be always the same as</b> <b>the actual distances.</b> <b>With subwoofer it's always going to</b> <b>be longer by the way</b> <b>because of the delays, the</b> <b>filters in sub-woofer cause.</b> <b>But also these</b> <b>distances are not important.</b>

<b>It's only the time differences between</b> <b>speakers that Acoustica works with.</b> <b>So they don't really mean much.</b> <b>If your front speaker is at 4 meters</b> <b>rather than 275 don't worry about it.</b> <b>It's about this distance, 2 centimeter</b> <b>distance between two that matters.</b> <b>And with that Acoustica is</b> <b>very precise I can assure you.</b>

<b>Time levels and crossovers everything set</b> <b>including bass, LFE for LFE to 200.</b> <b>So now it's all set and you can start</b> <b>listening and enjoying your system.</b> <b>But if you want to for example close this</b> <b>and rerun the optimization.</b> <b>Go to 2 and by the way let me show you</b> <b>also the results of this one.</b>

<b>You can see the clear</b> <b>selections like this.</b> <b>You can see the optimized calibration.</b> <b>This is going to be your</b> <b>front head speaker final.</b>

<b>This is going to be your front right</b> <b>speaker, SRA and subwoofer</b> <b>And this was how they</b> <b>were before optimization.</b> <b>So you can also save that as your result</b> <b>but it's not necessary.</b> <b>You can always produce this very quickly.</b> <b>As long as your measurements are the same</b> <b>the results will</b> <b>always be the same depending</b> <b>on the options you choose.</b> <b>Now let's remove all and then go back to</b> <b>my original measurements.</b> <b>Now you can adjust</b> <b>subwoofer EQ max boost.</b>

<b>I suggest keeping it at zero but you can</b> <b>use peaking filters</b> <b>too to boost the tips.</b> <b>But deep boosting is not a good way, a</b> <b>good sounding optimization.</b> <b>In fill just lift sub-volume up and down</b> <b>so you will have less dips for example.</b> <b>You can also use this if you took</b> <b>sub-woofer measurements off</b> <b>by 10 dB because with many</b> <b>measurements it's quite common.</b> <b>People forget to use LFE -10.</b> <b>LFE measurements by default are 10 dB</b> <b>louder than speaker measurements.</b>

<b>Dolby has 10 dB loudness</b> <b>embedded in LFE channel.</b> <b>So if you forgot to measure your</b> <b>subwoofer 10 dB lower then</b> <b>you can use the 10 dB here</b> <b>as the offset.</b> <b>That's the only reason there is 10 dB</b> <b>here otherwise it's</b> <b>really too excessive to use</b> <b>10 dB.</b> <b>Now night listening volume offset is set</b> <b>to 18 dB by default which</b> <b>means if you're watching</b> <b>your movies that there are 90 dB let's</b> <b>say which is -15 in</b> <b>these receivers and at night</b> <b>you put it down to -33 from -15, okay? Then</b> <b>you should keep it at -18.</b> <b>So how much lower is your</b> <b>low volume listening offset?</b> <b>If it's just 12 dB then bring it here.</b> <b>-12, -15, -18, -20, -25.</b>

<b>This setting will increase bass and high</b> <b>frequency level according to</b> <b>ISO 226 2023 equal loudness</b> <b>contour standards.</b> <b>Very precise, better than dynamic EQ and</b> <b>you shouldn't turn dynamic EQ on.</b> <b>Just offset here according to your taste</b> <b>and listening level and</b> <b>when you switch your amplifier</b> <b>to Audyssey 'Reference' that will be for</b> <b>your low volume listening.</b> <b>You will suddenly hear increasing bass</b> <b>and high frequencies.</b>

<b>So don't use this mode with regular</b> <b>volumes unless you're a real bass freak.</b> <b>That is where you want to listen and</b> <b>reference is only for</b> <b>night listening at low volumes</b> <b>at like low volumes like</b> <b>25 dB lower volumes okay.</b> <b>Here you can cap</b> <b>crossover search frequency.</b> <b>Normally it searches all the range</b> <b>available from 40Hz to 250Hz.</b> <b>You better leave them also at default but</b> <b>some people like to</b> <b>adjust their crossover</b> <b>frequencies to what they think is right.</b>

<b>So you can do that.</b> <b>If you take this one, this option, it</b> <b>will check for speaker</b> <b>polarities if there is any</b> <b>speaker out of phase and</b> <b>it will also correct them.</b> <b>You don't have to do anything.</b> <b>It's not always accurate but it's as</b> <b>accurate as it can be.</b> <b>If you get a positive just check your</b> <b>cabling, make sure that</b> <b>there is nothing wrong and</b> <b>if every connection is correct, every</b> <b>speaker cable is</b> <b>correctly connected then don't use</b> <b>it in the next optimization.</b>

<b>If you find some connection is really</b> <b>wrong don't change it</b> <b>physically but just use this</b> <b>one during optimization until you swap</b> <b>cables at one point</b> <b>because this will automatically</b> <b>switch the polarity of the speaker.</b> <b>And this is for DIY subwoofers or very</b> <b>powerful subwoofers which</b> <b>can go like below 16 Hz without</b> <b>losing any SPL.</b> <b>A1 is able to detect your subwoofer roll-off</b> <b>frequency as long as it is</b> <b>16 Hz and over but if it's</b> <b>below that it is not very reliable so</b> <b>this is for people who</b> <b>know their subwoofer roll-offs</b> <b>very well or who have a custom subwoofer</b> <b>that they have built themselves.</b> <b>So here you can select roll-off frequency</b> <b>goes down to I think</b> <b>10Hz minimum and roll-off</b> <b>shape also from Butterworth to Linkwitz</b> <b>Riley and Bessel and what have you.</b>

<b>So you have all these options.</b> <b>This is quite complex but people who know</b> <b>their sub roll will</b> <b>understand what is being</b> <b>done here.</b> <b>Normally you don't</b> <b>need to use any of those.</b>

<b>That's all the options in it.</b> <b>Let's talk over</b> <b>'Preferences' that you have to do.</b> <b>First of all go to view when you install</b> <b>REW, change maximum measurements to 1000.</b> <b>Just in case.</b>

<b>And 'Analysis'.</b> <b>Go to 'Equalizer' normally this is ticked 'drop</b> <b>filters if gain is small'.</b> <b>Untick this one.</b> <b>The API server normally</b> <b>stopped and you start it.</b>

<b>And if you're using your own microphone</b> <b>just make sure you add</b> <b>mic calibration file here.</b> <b>And sound card if you're using ASIO, if</b> <b>you're using your own</b> <b>measurements you have to do</b> <b>some settings here which I explained in the</b> <b>'Nexus' video but for</b> <b>Acoustica to work all you have</b> <b>to do is change the number of</b> <b>measurements here which</b> <b>will require a REW restart and</b> <b>in a equalizer untick</b> <b>this one, nothing else.</b> <b>And if you don't even want to do that</b> <b>here in the download folder</b> <b>there is a REW preferences</b> <b>file if you download this one and here</b> <b>you go to REW and load preferences file.</b> <b>If you select the downloaded file all the</b> <b>settings in REW will be set automatically</b> <b>without you doing anything.</b>

<b>And also A1 Evo when it's starting</b> <b>REW it starts REW with</b> <b>API server running so you</b> <b>don't also have to go</b> <b>to API and start server.</b> <b>There are known problems with</b> <b>the transfer tool at the moment.</b> <b>Let's mention these.</b> <b>If you have four subwoofers and one of</b> <b>the new models, it tends</b> <b>to mute two of them so</b> <b>until this is resolved you</b> <b>can't really use Acoustica.</b> <b>Acoustica's transfer tool at least.</b>

<b>And with certain models also reference</b> <b>filters are not working I think.</b> <b>But the good thing is it is available on</b> <b>GitHub, totally open source and developers</b> <b>are invited to fix these problems because</b> <b>you need to have this particular model to</b> <b>really test it properly.</b> <b>I can only test my own and as much as</b> <b>friends in the forums give feedback.</b> <b>But I completely opened it including the</b> <b>transfer files and</b> <b>everything here so developers are</b> <b>very welcome to improve at</b> <b>least the transfer function.</b> <b>Don't use GitHub for asking</b> <b>user problems for the tool.</b> <b>For that there is the Facebook group,</b> <b>there are forums and there</b> <b>is also the YouTube comments.</b>

<b>Here, please use it for development.</b> <b>It needs a measurement tool.</b> <b>We are now aware that we can use Audyssey</b> <b>measurement tool manipulated</b> <b>to actually even individually</b> <b>measure subs.</b> <b>Many of these receivers</b> <b>can do directional bass.</b> <b>By the way if you are measuring manually</b> <b>and you have more than</b> <b>one sub put your amplifier</b> <b>to directional bass mode during</b> <b>measurement so you can measure</b> <b>individually each sub.</b>

<b>Otherwise you have to swap RCA cables</b> <b>during measurements because</b> <b>you have to have individual</b> <b>measurements if you have multiple</b> <b>subwoofers that's important.</b> <b>But we know that we can even override</b> <b>that and measure subs</b> <b>individually using Audyssey</b> <b>measurements.</b> <b>But I didn't have time to write that part</b> <b>and hopefully somebody will add this or I</b> <b>will do it if I can find the time.</b>

<b>So this is in the to-do list.</b> <b>So, compatibility to all the</b> <b>models and a measurement tool.</b> <b>For example someone developed already</b> <b>here is also open source</b> <b>and in GitHub a tool for</b> <b>automated REW measurements.</b>

<b>So opportunities are infinite.</b> <b>The optimization technique is very</b> <b>sophisticated and the best</b> <b>yet. I'm pretty certain you will</b> <b>all love the results as</b> <b>long as your filters work.</b>

<b>So let me know in the comments if you</b> <b>find the tool useful and</b> <b>if you run into any issues.</b> <b>What else can I explain?</b> <b>Okay the target care library as you see</b> <b>in the video download</b> <b>folder there are lots of</b> <b>target curves. Download this</b> <b>and use a custom target care.</b> <b>Evo Acoustica is good for a standard</b> <b>calibration but if you find</b> <b>the bass too heavy you can</b> <b>switch to another curve.</b>

<b>A lot of people are doing their custom</b> <b>target curves lately.</b> <b>Before you start optimization you have to</b> <b>go to EQ, target</b> <b>settings and here 'house curve'</b> <b>and select one of the curves in this</b> <b>target curve library or a</b> <b>custom curve that you designed.</b> <b>That's important to start optimization it</b> <b>will give you an error otherwise.</b> <b>What else?</b> <b>Acoustica is capable of hacking the 6</b> <b>meter maximum</b> <b>distance limit in Denon/Marantz</b> <b>receivers.</b> <b>You can use up to 7.35 but</b>

<b>there is a trick with that.</b> <b>If your calibration optimization use the</b> <b>limit higher than 6</b> <b>meters it will work but only</b> <b>until you go in the setup menu and try to</b> <b>edit distance settings.</b> <b>If you try to edit them then it's going</b> <b>to cap them back to 6 meters.</b> <b>So if you get a warning during</b> <b>optimization that Acoustica</b> <b>is using a higher limit than</b> <b>normal for your system then do not go and</b> <b>edit speaker distances in your receiver.</b> <b>And another thing I should tell you: don't</b> <b>trust Web UI! It has lots of bugs.</b>

<b>Let me go again.</b> <b>For example speaker</b> <b>distances do not update in Web UI.</b> <b>So you might send the calibration and see</b> <b>here that nothing has changed.</b> <b>This is because Web UI doesn't update.</b> <b>And one last warning is double check your</b> <b>'amp assign'</b> <b>configuration after the filters</b> <b>are transferred.</b>

<b>Make sure that it's the same.</b> <b>Because especially with external</b> <b>amplifiers I see that my</b> <b>pre-out fronts switch to pre-out</b> <b>rears randomly.</b> <b>All you have to do is switch</b> <b>it back and then it will work.</b> <b>And this is also valid for the cases</b> <b>where multiple subs are muted.</b> <b>You just go turn them back on.</b> <b>Hopefully all these</b> <b>problems will be sorted very soon.</b>

<b>And that's all for today.</b> <b>Enjoy your sound and Good-bye!</b>
