- Every day we receive great comments about RoomPerfect and how it improves the sound from your loudspeakers in your room. For everyone who wants to know how to get the best performance from RoomPerfect and how to do it right, watch our new video.
Amazing technology which delivers the best possible performance in any room.
Thank you for the nice feedback.
In your tutorial you say at the beginning that Room Perfect will first run a signal to determine the optimal volume level, required for calibration, then shortly after, you say that we have to raise the volume, manually (??!)
It is unclear here, the software doesn't regulate alone the optimal volume, depending on what it received with the first signal emitted? do we have to adjust the volume too? If so, how do we know how loud to give it so that to not be too much and the results obtained are incorrect?
RoomPerfect will first run a signal to determine where the volume level is. It might be already at a useful level. If not, the app screen will recommend a level which is useful in these speakers in this room. You can raise it up to that level, or (if it seems much too loud, for example when it bothers others) chose a lower level and continue. But if you can, set it to the recommended number, so that the signal really excites the room acoustic problems and they will be addressed in the correction later.
@@SteinLyng Thx a lot. Now it's clear for me.
Do you make or have any plans to make a preamp with room correction? Thanks
The idea is certainly worth considering, but not so soon because there are two options already: On both the TDAI-1120 and TDAI-3400 (or even the older TDAI-2170), the power amps can be disabled in the settings, and the TDAI can already be used as a pre-amp with RoomPerfect, or even as a RoomPerfect processor only, using the analog or digital pre-outs.
@@SteinLyng Ok, I didn't realise you could do that, although I wouldn't want to buy one and turn part of it off.. I think a lot of people would love a balanced preamp with your room correction, XLR in and out, using there own streaming devices and power amps. Still let's the audiophile tinker with different streamers and power amps whilst using your excellent room correction system, you could probably make a preamp to end all preamps... Basically please make a balanced preamp with your room correction 🙏🏻🙏🏻🙏🏻😂👍🏻
Thanks for the great setup video.
We are glad you like it 👍🏻
can you make a how to for their mp receiver lines? seems that youtube is lacking educational videos for lyngdorf
Thanks for your feedback - that’s exactly why we started doing more and more educational videos. Recently six for our latest TDAI-1120, this new RoomPerfect video, and more to come. RoomPerfect for MP is not that much different, but it requires more setup points in the browser menu first, as well as maybe some do’s and don’ts with the mic in the room. By the way, you can find all videos on our website, too: lyngdorf.steinwaylyngdorf.com/videos/
Hello RoomPerfect is the best room correction technology I have use so far in my homes.
I started with a TDAI 2170, that I still have. Now I have an MP multichannel processor. I have a set up question please :
I have two MK X10 sub woofers in the front corners that can go until 200hz, and MK THX satellites that can go down to 80Hz. Shall I set the cross overs for the subs the same as front speakers ? Or like for the TDAI it is better to set the maximum cut off frequecies (200hz and 80Hz) and Roomperfect takes care of the rest ?
Many thanks.
Hi Hugo
We recommend that you use the crossover filter in the processor so if your sub has a built in crossover, it should be disabled or the crossover frequency placed as high as possible. If the sub has a LFE input you can use this, it will typically bypass the crossover. When choosing a crossover frequency it should be placed well away from the speakers natural roll off. In this case you could choose 120-140Hz. On the speaker setup page choose XS for the sattelites, this will place the crossover at 120Hz. If you want a higher crossover frequency, choose Custom and put in your crossover frequency of choice. Remember that any change to your speaker setup requires a new RoomPerfect calibration.
@@SteinLyng thank you very much for your detailed answer !
So does that mean that in the set up menu, if I choose speaker size XS (120 hz) I should sélect « LFE Channel cutof » at 120 hz too or a bit more, knowing the subs can go theoratically until 200 hz?
Many thanks
Greetings from France.
I have the 2200 RP but I can't do the measurement cos the level is to low. I've raised it to what think is healthy for my speakers(Dali Grand).
In the usermanual it says that in some rooms it can't measure cos it's too "noicy".
I will get in contact with customer service, but it could be something simple that it can solved in a YT-thread.
RoomPerfect requires a rather loud measurement signal to really capture the sound energy in the room. But if it seems way too loud to you, it could be that the microphone or cable connection has a fault and the signal only seems too low at the receiving end. The RP microphone hasn’t changed from TDA 2200 to today’s TDAI amplifiers, so it’s worth borrowing a RP mic and cable from a nearby Lyngdorf dealer. A “noisy room” can likely be ruled out, because that would require some rather loud and constant external noise, like roadworks or a hoover… otherwise, RP is quite tolerant. Yes, good idea to contact our product support team (via our website), and let them know the volume level number which RP seems to require. We can check whether that’s realistic.
@@SteinLyng The jackstick contains 4 rings/connections. Should they be separat ? Cos theird & fourth from the tip soldered.
@@1973Grejluder The RoomPerfect microphone has three pins, therefore the original minijack connector cable also has three metal contacts, with two separating plastic rings. This means you probably have a wrong connector cable in your hand. We suggest to borrow an original RoomPerfect connector cable from a Lyngdorf Audio retailer, which is still used in today’s TDAI-3400 (the one you can also see in the video). Otherwise, if there’s no retailer around your place, send a short email to our product team via the website (click Support).
I thought you were supposed to do measurements with the microphone directly aimed at the speakers to register the sound characteristics. Was that skipped because these are Lyngdorf speakers?
It was always the same principle since RoomPerfect started: First focus measurement is with the mic aimed at the speakers as in the video, to have an accurate reference from the speakers. Following mic positions can aimed at the speakers but should be in many different directions, varying in a random way, to capture the room acoustics (not only the speakers). It’s a unidirectional (cardioid) microphone, so the exact degree doesn’t matter so much.
Does it automatically set the frequenz of the sub and the volume?
Do i have to open the crossover of the sub max and the volume at 12:00 o clock (half power)?
RoomPerfect does not overrule the set crossover frequency (meaning the low pass and high pass filters set by you in the TDAI or MP), because the crossover frequency depends on your subwoofer type and frequency range (or recommendation from the manufacturer), and on your speaker type and frequency range (or recommendation of the manufacturer). As you can imagine, that can be very different crossover frequencies from system to system. Regarding the subwoofer itself, you are right that you open the crossover or frequency range as wide as possible, because you’ll set it in the DSP of the TDAI or MP (or set the Subwwoofer to bypass).
The volume level, especially in the area between subwoofer and speaker, will be aligned and optimized by RoomPerfect. But as you write, you have to give RoomPerfect a starting point, and that can be somewhere between half power and max power. Then RoomPerfect will be able to tone it down, if needed, but at no risk to overload the subwoofer.
After the measurement do i have to regulate the subwoofer Crossover back from Max to 80 Hz for example? I know that i can set the frequenz in the app, but i recognized that the App dont cut out the Frequenzen above. For example: in the App 80 Hz is set, but i go to the sub and Change the Crossover for example to 100 Hz it becomes louder. I dont understand that because i thought the App Cuts the frequencies off like a filter
@@arnonym823 No, the subwoofer setting (on the subwoofer) should not be changed after the calibration, otherwise the calibration would be partly wrong. So Max is the right setting.
If the crossover is set at for example 80Hz in the app, this is never a “brickwall” filter which “cuts” the frequencies, but the frequencies become gradually weaker (less loud) above 80Hz. This can be set steeper or less steep, depending on the filter slope (higher numbers like 8th is a more strict filter than lower numbers like 2nd - you can also see that in the frequency graphs). This means you will still hear a change, and hear more bass, as you describe.
I've found it necessary to use both speaker presets on my TDAI-3400; one ONLY for couch listening, and the other for when I listen to music on the other side of the living room. I only have acoustic panels for my listening area, and the other half of the living room is almost completely empty (I use it as a workout space).
If I measure the listening space with the microphone higher than the focus position, it seems to pick up on the crappy acoustics in the other half of the room, making complex music sound noisy and messy. However, it also cleans up most music genres around my workout space. Not sure what else I can do, except fill the entire 40 square meters with acoustic panels, which I am not willing to do. For now, preset 1 is for critical listening, and preset 2 for workouts.
Good solution - that’s what the 2nd speaker setup is for, even if the second speaker pair is the same.
For the main listening area, you could keep the microphone mainly around the main listening are, not move to the farther part of the room too often. If the other half of the room has an acoustic impact on the main listening area, it’d be detected by the mic and covered by RoomPerfect.
Before doing any new RomPerfect round, you can save a Backup on SD or USB, so you can always go back if you preferred the former outcome.
Hello one question too please:
My room is an open space rectangle composed of a living room (listening area) and a dining room. Should I make measurements in the dining room as well ? There are no walls between and the dining room has more volume.
Many thanks
Hi Hugo
You should only do the measurements in the listening area.
@@SteinLyng Understood, thank you very much for your fast reply !
Hi. Just one question. Do I keep the mic parallel to the floor all the time and just change directions or should I do different angles? Pointing at the ceiling etc. Thanks.
The RoomPerfect mic is cardioid/omnipolar, so the exact direction or angle doesn’t matter so much. It still should be angled to make sure you get different and random results, but it’s much more important to change the mic stand placement in the room, and change the mic stand height.
What are that stands? Could you link me them?
The stand is part of the complete RoomPerfect set, which can be purchased at a Lyngdorf Audio dealer. But if only the stand is missing, any good microphone stand can be used, as the RoomPerfect Microphone only uses a common plastic clamp to fix it. We have good experience with the stands from König & Meyer.
@@SteinLyng I’m sorry, I expressed wrongly my question. I meat the “speaker stands”, what are they exactly? I owe a 3400 and thinking to try the FR-1, but I won’t surely make holes in the walls…
@@RiseFall123 We admit a little trick here - the FR-1 are on-wall speakers, but for hifi shows, exhibitions and filming we made some temporary stands to hold the FR-1’s wall bracket! There are some height-adjustable speakers stands with smaller top plates or L-shaped mounting top plates available.
@@SteinLyng then the stands that you use are not on sell? What company did you contact to build this "custom" stands or you buld them yourself at Lyngdorf's?
Is RoomPerfect just an automatic calibration?
Or can we also manually play the base EQ that Room Perfect does?
Written with Gogle translator
Greetings and thanks for the video
It’s an automated calibration where the measurements of the advanced RoomPerfect result cannot be manipulated afterwards. However, there are three ways for you to fine-tune the result: 1. Add more measurements, for example to increase the room knowledge and address room acoustical issues further. 2. Select one of the Voicings or creating your own Voicing, which adds a sound EQ in the DSP to RoomPerfect. 3. Choosing between RoomPerfect Focus and RoomPerfect Global, where Global is a less strict correction at the listening seat and therefore more suitable across other seats. You can also save more than one RoomPerfect measurement and compare afterwards. So there’s a lot to play with…
@@SteinLyng Thanks for the deference in answering.
One more query if it can be.
Can you choose the target in dB in Room Perfect?
I explain:
There are automatic corrections that its target is 75 dB and due to the circumstances, the room-loudspeaker combination produces valleys that in a priori it is not advisable to equalize.
Does Room Perfect give the option to choose that target in dB and put for example 70 dB and not 75 dB?.
@@JuanJose-wt5yj Thanks for pointing that out - it’s true that many room corrections ‘blindly’ fill frequency dips and equalize everything. While a dB number cannot be set, RoomPerfect will never equalize everything, nor does it even aim for a completely flat frequency response. From a development point of view, RoomPerfect started several years ago with our engineers as well as music listeners being disappointed from typical electronic room correction systems, which ‘over-correct’ everything, robbing music of its dynamics and energy or overpowering the speakers while trying to equalize dips. That’s exactly the difference of RoomPerfect. Typically listeners and reviewers who are not fond of corrections are surprised by RoomPerfect.
@@SteinLyng That is why my query, to see the power of Room Perfect, customizable manually to the taste of each person.
Since the most complicated area is usually from the critical frequency of each room to 250-300 Hz, just the area where there are usually more narrow peaks and non-equalizable cancellations and that yours is to decide by ear.
Hence my query about the power of Room Perfect when it comes to being as customizable as possible, knowing that it is an automatic correction.
Thanks for the explanation.
Excuse me if I do not explain any comments well, since I use the translator.

100 times better then DIRAC...
We are glad to hear you like it.
@@SteinLyng Peter lyngdorf back to core for ever ✌️
Have you been able to compare in a rigorous test if it is better than Dirac?
Greetings
@@JuanJose-wt5yj Yes
@@matrix101redorblupill4 Have you commented on it in a forum where you can see it?
Were the tests objective and rigorous?
