YPAO – The Lost Manual
If you have a Yamaha receiver, check out YPAO – The Lost Manual on how to configure Yamaha YPAO to get the best performance out of your receiver. Get it here.
Cinema versus Home
Movies are designed for the big screen and movie soundtracks for the big auditoriums of cinema multiplexes. When played back through a home cinema system in a smaller room, the perceived tonal balance of the soundtrack changes.
Tonal Balance: in simple terms, it is the amount of perceived bass, mid-range and treble present in a soundtrack.
All modern receivers have a way to combat this through equalisation of the speakers / room and filtering of the high frequencies which removes the perceived treble push of smaller, undampened spaces like your living room. However, you may notice that even after such equalisation, something is missing no matter how loud you play your equipment. This is because the big cinema auditoriums have different reflection and reverberation of the sound as it bounces around the room than in a smaller room.
This is what Yamaha went on to solve using their expertise in musical instruments and sound recording. Enter Yamaha Cinema Digital Soundfield Processing (DSP),
Yamaha Cinema DSP
Yamaha knew about this issue before all other manufacturers and they went onto recording and analysing the real-world behaviour of sound in cinema (and other) spaces. The extensive amount of data collected allowed them to digitally recreate the spaces using digital signal processing and in 1985 they released the Yamaha DSP-1, a standalone processor that could re-create cinema soundtracks as if they were being played back in a cinema.
Fast-forward almost 30 years and Yamaha’s Cinema DSP is in all Yamaha Home Cinema Receivers and have advanced to a point where it requires serious attention from anyone interested in home cinema.
What you need
You will need
- A recent Yamaha Surround Receiver with at least 7.1 channel capability. Although Yamaha’s lower end units can do virtual Cinema DSP through a 5.1 set-up, it is not nearly as effective as having separate speakers.
- An additional two speakers that will be used for the Front Presence speakers. They can have lower power handling and efficiency than your main speakers. Small bookshelves or satellite speakers will do with a frequency response from 100Hz to 20Khz.
- More wires
In essence, Yamaha’s Cinema DSP reproduces the reflections and reverberations of the cinema spaces through 2 height speakers at the front called Front Presence Speakers. Although you can use the front left and right speakers to reproduce the soundfield (called Virtual Cinema DSP), it produces a muddy and indistinct sound and does not compare well to the real set-up.
Yamaha’s more advanced Cinema DSP called Cinema DSP HD3 uses an additional set of speakers for the back soundfield called Rear Presence Speakers. When using DSP HD3, the Front Presence Speakers are more important to install than the Back Presence Speakers. Please see the full configuration below:
Cinema DSP 3D and Cinema DSP HD3
Cinema DSP 3D only has the capability to use Front Presence Speakers. Yamaha’s lower and mid-range receivers have this version. The rear soundfield data is mixed into the surround speakers. For this reason, it works better if the surround speakers are not at ear height but at least half a meter or more above the listening plane.
Receivers of this class are capable of 7.1 or 9.1 channel output. For 7.1 channel receivers, the back surrounds will not output sound when the Front Presence Speakers are being used by Cinema DSP. The 9.1 channel receivers have the capability to power all 9.1 speakers at the same time.
Cinema DSP HD3 improves on 3D with two things:
- An additional two channels at the back (Rear Presence Speakers) that only reproduce the CinemaDSP effects for additional clarity. This expands the speaker configuration to 11.1.
- Double the processing power to calculate more precise soundfield data both in the frequency and the time domain. For example, this means that sound reflections are tracked in space for double the time than with DSP 3D providing even more clarity.
From Adventure to Sci Fi
When Cinema DSP is configured well, you will experience your walls literally melting away and your home cinema opening up to sounding like a big movie theatre. To configure it, do the following:
- Ensure that the Front Presence Speakers are placed wider and higher than your front left and right speakers.
- Run the YPAO automatic calibration even if you will not use the EQ function of your receiver. This is because higher end Yamaha receivers will adjust the Cinema DSP parameters dependent on the already existing acoustic characteristics of your room.
- Select a Cinema DSP program (called movie) on your Yamaha Receiver.
There are 6 movie soundfields on all modern Yamaha receivers. Read your Yamaha manual to understand the differences between them. As a guide:
- Select Sci Fi for any action or Sci Fi movie or where the soundtrack has lots of precisely steered effects.
- Select Drama for movies with lots of dialog or for TV programs.
- Select Adventure or Spectacle for older movies or movies with big musical scores.
- Mono movie for – you guessed it – mono movies.
- Select Standard when no other soundfield sounds right for the movie or when you want to leave the front soundstage intact.
In addition there are many parameters you can adjust for each soundfield to make it sound less or more spacious. It is rather difficult to configure these manually, so download the Yamaha iPhone and Android app to your phone that allows you to configure them easily.
I recommend this even if you have an older receiver that doesn’t allow you to configure soundfield data using your phone. You can simply use the app in demo mode and copy in the parameters using your remote manually.
What about other manufacturers?
Even though other manufacturers have started using DSP soundfield programs, they don’t have the sophisticated algorithms Yamaha uses. Most simply add echo or reverb to the soundtracks to create some kind of effect as opposed to precisely measured soundfield data. I recommend auditioning the difference between them.

Configuring YPAO – The Right Way
When you have Front Prescence speakers installed, I take it VPS doesn’t then create Rear Prescence ones instead, if On?
Yes, the newer receivers do that, the older ones don’t. I think virtual rear presence was introduced in RX-A3050 onwards. The difference really comes with ATMOS and DTS X though where the extra speakers make a much more distinct difference, but the yamaha is very good at virtual mapping as well.
Really great article and a lot of useful information, i just have one question regrade the front Presence Speakers, is it really necessary to place them wider than front left and right speakers to get better sound quality?? as am using 5.2.2 channels and placed my front Presence Equal width with left & right speakers.
Not really necessary with the latest receivers that have Dolby Atmos! The new units compensate for varying speaker placement much better. 🙂
Hi there, is it best to choose this DSP over the surround up-mixer if you have a full atmos setup?
I would choose the Enhanced DSP with all modern movies and definitely with Atmos / DTS X
I am new for RX-V6A.
What is app for iPhone to set and visualize DSPs mentioned in the article?
It’s called the Yamaha AV Controller 🙂
Hi, I have a RX-870 with DSP-3D. I wanted to add a 2 channel amp to have 7.2.2 and am wondering if when i add the amplification I will be able to have the overhead speakers and back speakers work at the some time. My amp has 9 sets of speaker terminals and preouts but on only 7 amps.
It’s only a 7.2 channel amp so you likely won’t be able to get 7.2.2 out of it. It will either drive the back speakers or overhead speakers.
You will need an additional separate amp to drive the additional pair of speakers.
Your original amp will be able to process the speakers but not drive the 7.2.2 setup.
I’m using a standard 5.1 setup with full Cantons’ (small speakers) and the Yamaha RX-V773 receiver, would I benefit of using the Cinema DSP 3D mode when watching movies? I usually use ‘Straight’ mode when watching Blu-Ray movies, and ‘Surround Decode’ on Neo:6 Cinema when watching movies or shows via TV.
I’d also like to take the opportunity to thank you for your other guide regarding YPAO calibration. I had no previous experience of YPAO coming from my older Yamaha YHT-196 system.
Thank you, Emil and sincere apologies for the very late reply. I had some comments I didn’t notice I missed.
Yes, I recommend you to try CinemaDSP modes and see which ones you prefer. My favourites are Sci-Fi, the latest Enhanced program and also Drama for dialogue-heavy movies and TV shows.
I’ve got a Yamaha RX-V583 and have the AV Controller app installed. However, I am not able to bring up the DSP settings to adjust the sound field whenever I want – Does it matter what I’m watching
PS: I can press DSP and bring up the various pre-set sound set-ups but not the 3D field
PPS: I’m running 5.1
Hey there, I think your amp may not be able to do 3D field if it’s greyed out. Not all amps are compatible with all settings. Lower end amps can do DSP but not 3D DSP.
So it seems to work sometimes – I’m putting it down to the type of signal being fed
Looking at the field, it really makes me want to go down the atmos route – I currently only have 5.1
I’m looking forward to trying this as I have just purchased four ceiling speakers and will add them to my 7.2 bi-amp setup with my RX-03030. It says I will need to use the front and rear presence low level outputs to attach a second amp to drive the ceiling speakers. This way, I can continue to bi-amp the front mains and still use all four ceiling speakers. This should give me bi-amp 11.2 setup. Or, what Atmos users would call a 7.2.4 setup.
Since the ceiling speakers will not be as critical for the main music/movie sound, I will use a smaller amp.
Does anyone know if YPAO does a good job in this mode?
Wrote a longer reply then WordPress decided to crash. YPAO will do fine, but pay attention to the trims not getting maxed out due to incorrect volume setting on your external amp,
Thank you for pointing that out. So, is the low impedance output on the RX-3030 variable and YPAO sets the level or will I need to measure and manually set the external amp level?
Great article. Q. do you recommend eg that a Atmos track from a 4k DVD, also needs to have a DSP applied, or does ‘Straight’ give the best listening. ie does the DSP mess with how the track is designed?
Hi Peter, thx for that.
The DSP Programs have been updated to be overlaid over Atmos and DTS X since the xx60 series so they will work fine.
Yamaha also designed a new DSP program called Enhanced for specifically object-based soundtracks which you can use with Atmos and DTS X.
I still prefer Sci Fi but the Enhanced program is quite good as well. 🙂
thanks, I will try out the Enhance option. I have experimented with mainly ‘Standard” ‘Drama” and ‘Straight” and having AI on and off. Cant quite settle on what I think sounds the best. Other AV type sites, have not been clear about how DSP interacts with modern soundtracks. (I have a RXV1085)
Drama is great for dialogue-heavy shows so good for TV.
Reviewers normally dismiss DSPs as just fancy reverb which is true for other manufacturers but not for Yamaha. Yamaha has put a lot of thought into them since their DSP-1 in 1985. 🙂
finally brought a copy of your YPAO manual, now that I have purchased a RX-A4A after my RXV-1085 blew up. In the 4 years I had it it was in the repair shop 3 times. – bit peeyed. Hopig the new one with the longer warranty will last. My first Yamaha AVR lasted 10 years. Anyhow loooking forward to setting it up well. Regards
That’s great, Peter.
That’s not great about your AVR, but sounds like you stuck with Yamaha anyway because you love the sound.
Looking forward to hearing about how you go with setting it up using the guide! 🙂
Roland, great article. Q. when playing a Atmos track from a 4k DVD,do you still apply a DSP or playback using ‘straight’.? It confuses me as to whether the DSP messes with how the Atmos track is meant to be.
Btw, the DSPs (apart from Surround:AI which I don’t recommend) will keep the integrity of object-based soundtrack (tonality, directionality and steering) so no issue using them.
Please refer to below two articles and an additional pro guide for more
Thank you for this excellent article, which I’ve been referring to since my first DSP-enabled receiver from a few years ago.
I previously used wall-mounted presence speakers (higher and wider!) to create the DSP effects, but now I have an opportunity to put in ceiling speakers for Atmos. If I follow the Atmos placement guidelines (wider, higher, but only slightly forwards of the listener) will DPS settings still be effective?
Thank you for your readership.
Theoretically, no difference, but of course there could be some even due to new speakers, different dispersion, etc.
If you feel the effect is too much or too little, go into the DSP settings and adjust the strength, etc. You may need to play around with it until you find an optimal setting again.
Let us know how you go! 🙂
Brilliant – thank you. I didn’t want to throw away DSP in the transition to the Atmos config, since the DSP effects really complement movies on the projector (and actual Atmos tracks only make up a small minority of my media).
I’ll try it out and report back!
Yes, absolutely agree. CinemaDSP is great! Yes, please let us know how it goes.
