ADA Suite 7.1 HD AV Processor Review

Setup & Parametric EQ


Since the introduction of HDMI a few years back, there have been precious few AV Processors supporting onboard HD Audio decoding released. Those that have made it to market, more often than not well after their anticipated release dates, have either been plagued with bugs or so crammed full of (unnecessary?) features, I am left wondering how much of my hard earned would actually end up improving on the sound quality of a High End AV Receiver or legacy (non-HDMI) Processor.

When Audio Design Associates announced their new ‘Suite 7.1 HD’ it really piqued my interest. I had the pleasure of hearing the predecessor, the similarly named ‘Suite 7.1’,  a few years back at a High End Home Cinema Demonstration put on by Genesis Technologies at JVC headquarters in London and was very impressed.

Of particular interest to me given my personal feelings about the apparent preference for the major AV manufacturers to chase ever lengthening spec lists over outright sound quality, was the relatively modest feature list of the ADA Processors, in particular a lack of on-board Video processing and Automated Room EQ. Whilst I don’t for a moment ignore the benefits of such features in an AV system, I do question whether the best place for them is within the same chassis as the Audio Processor itself and I do like to choose the features I am spending my money on. ADA’s philosophy of keeping things separate means you can do just that and lets face it, if you are in the position to spend £5K on an Audio Processor, you are probably not as concerned as some about spending a bit more for an equally high end Standalone EQ device or Video Processor of your choice.

Richard Stoerger, the CEO of Audio Design Associates, was kind enough to write an introduction and brief history of  ADA, which I have included in the appendix for your interest.

ADA products are distributed in the UK by Genesis Technologies and the units used in this review were provided by Elliot Hicks from ‘Complete Home Control‘.

The Suite 7.1 HD MSRP is £5300

If you have read the ‘History of ADA’ in the link above you will know ADA products are primarily aimed at custom installers who have been trained to setup all aspects of the system for their clients. The Suite 7.1 HD is not a plug and play device and anyone considering purchasing one without having it professionally installed or calibrated should bear that in mind.

As there has been quite some discussion about the Suite 7.1 HD over the last few months on the forums, I decided to stick my neck out and see just how easy (or difficult)  it would be to do everything without a trained installer.

Suite 7.1 HD Overview

The Suite 7.1 HD is an HDMI Audio Processor with HDMI Video Switching and pass-through. It decodes all the latest Audio formats, such as Dolby TrueHD and DTS-HD MA as well as accepting LCPM over HDMI and all the legacy codecs you would expect via HDMI, Optical and Coaxial SPDIF.

Being a diminutive 1U in height it does not have room for 8 channel analogue inputs (check out the Rhapsody Mach IV) but it does have  4 pairs of stereo analogue inputs, 6 Coaxial SPDIF and 2 Optical SPDIF inputs and the obligatory 7.1 channel outputs.

As the Processor is focused on digital sources it is pleasing to see they haven’t scrimped on the HDMI connectivity, with 8 inputs and 2 selectable outputs.

There are no legacy Video inputs or outputs and therefore no up-scaling or indeed any Video processing whatsoever. This is a refreshing approach when so many manufacturers cram as much in as possible onto ever more imposing chassis.

Audio processing includes several THX Modes as well as Dolby Volume and some interesting proprietary ADA processing modes.

Other connectivity includes an RJ45 LAN connector for direct access from a PC or Network Switch, a single 12v Trigger and the proprietary (sort of) ADA Bus (more on these features later).

This all seems pretty standard stuff and at a glance you could be forgiven for thinking the ADA has quite a limited specification but where ADA stands out from almost all other manufacturers I have come across, is in the customisation that is available which I shall touch on later in the review.

First Impressions

The first thing of note upon the arrival of the Suite 7.1 HD is just how light the shipping carton was is in relation to it’s size. I was expecting the ADA Processor to be lighter than most of the full size chassis Processors and Receivers I have become accustomed to but this was still quite a surprise.

Opening the carton revealed what appeared to be plastic covered vacuum formed polystyrene mouldings (I am sure there is a technical description for this but for now it escapes me), anyway suffice to say the contents are very well protected from intrusion by foreign objects and also hold the contents very securely.

To anyone familiar with the plethora of manuals, stickers, calibration mics, remotes and other accessories that come with most modern Processors and Receivers, the contents of the ADA carton are austere to say the least. The Processor itself is wrapped in a large thick plastic bag  and beneath it coiled in place is a power cable… and that is it. No manual no warranty certificate, nothing. Now this was not totally unexpected having followed the product since its announcement but for those unfamiliar with the Suite 7.1 HD, it may come as a bit of a shock.

Since this review was started some weeks ago, ADA has finally completed a comprehensive Manual which I have included links to in the Appendix at the end of the review. As you read the review please bear in mind the Processor was setup by me without any reference materials to turn to, so any new purchasers are likely to have an easier time of things than I did.

The unit itself comprises of a faceplate with rack-mounting ears for a typical 19” rack (but is also available in a non-rack mount version shown in some of the images within this review). The chassis is built entirely from aluminium contributing (or not) to the unexpected weight of the unit, as well as being an excellent conductor and radiator of  heat generated by the Processor. The front panel is austere with a small illuminated display panel lit in a yellow/green colour and only 3 black aluminium knobs grace the front panel and are the primary controls for the unit. The only other features are the power switch and the ‘Display’ toggle which to the best of my knowledge changes the brightness by about 20% and as such is somewhat superfluous. Perhaps a greater level of contrast or turning the display completely off might have been more useful. You can however set the display to turn off automatically after a set time as seen on page 41 of the manual.

The quality of the finish is good but there is little in the design to reflect the Price tag (a positive in some cases, making it all the easier to smuggle past SWMBO) and anyone expecting the sort of finish and design touches that some manufacturers at this price point imbue (I am thinking of  Arcam, Parasound Etc.) may be a little disappointed. Certainly some may expect more attention to detail at this price point but as a product aimed at custom install, destined to be hidden away in a rack or cupboard, I get the feeling the designers had other priorities.

Some points of note with the finish include what appear to be superfluous screw holes in the top which highlight the use of the same chassis components over several of the (many) products manufactured by ADA. As a graduate in Manufacturing Systems Engineering, I doff my cap to any company with the forethought to minimise manufacturing costs by sharing components across a range of products. It is little details like this that hint at ADA’s priority on delivering on Audio performance and value rather than aesthetic niceties. Whilst having both would be pleasant, I know where my own priorities lie and personally I have always been a fan of the understated. Given the option of paying another 20% or so for something that looks nicer for no performance benefit isn’t really on my agenda but this is of course just my opinion.

The knobs and switchgear on the front panel all have a firm, quality feel about them and rotating the solid aluminium dials, or pushing them in to make a selection in the menu, gives a reassuringly solid feedback. However I can’t help wishing that ADA had considered moving to a more conventional 4-way jog-dial type interface, rather than the knobs which are not ‘standard’ interface design elements and therefore ask something additional from the user in terms of getting to know the product. However I am particularly conscious of User Interfaces as I design them for a living, so perhaps I am overly critical here, though even the Installation Manual suggests ‘…using the PC program when ever possible as it is more intuitive’ and I completely agree. I am also aware of what it costs to develop interfaces and can see why ADA have chosen to stick with a legacy method that works, especially when it is unlikely to be used very often thanks to the excellent software provided.

Build quality wise the only thing that concerns me are the 12v Trigger and ADA Bus connectors which seem a bit delicate and are quite wobbly. However unless you expect to be constantly using these then I think you would be hard pressed to do any damage. I have been using them quite a bit as I have been experimenting with different setups, control devices and cables etc. and despite the fragile feel, they haven’t displayed any sign of breaking.

Like any impatient child with a new toy, I couldn’t resist a quick play after minimal setup and the initial impression put a big smile on my face but I’ll leave a fuller discussion, sobered by a couple of months of living with the Suite 7.1 HD, until later in the review.

Fan Noise

Due to a miscommunication, I was initially sent a Rack Mounted version of the Suite 7.1 HD which posed some slight difficulties in reviewing the unit as it would not fit in my rack. I did manage to get round this temporarily and one of the first things I noticed when switching the unit on was the fan noise.
I would probably compare it to an early Thomson Sky box in one of its noisier moments. It wasn’t the end of the world but definitely something a potential purchaser would need to consider. Anyone viewing a film with a projector somewhere overhead would be unlikely to find it an issue though. Let us of course remember that the Suite 7.1 HD is primarily designed to sit within a rack of unknown ventilation/cooling characteristics, so having a fan is a necessity really. However having one in a rack located in the listening room may have disappointed music fans especially during quieter moments.

A couple of weeks later the non-rack mounted version arrived and to my surprise it was completely silent. There is still a fan present but it has been replaced with a much quieter version, in fact it is so quiet I would term it ‘silent’ and I am someone who is very fussy about fan noise. It seems around the time my first unit arrived a couple of comments about fan noise from owners appeared on the forums and almost immediately ADA changed the new units being shipped to respond to customer feedback. You don’t find many manufacturers that respond so well and promptly to feedback and for this ADA should be commended.

  1. Update: I have just had confirmation that Dolby Volume is not actually active on the Suite 7.1 HD, apparently due to a bug in the Dolby software. ADA will be adding the feature in an firmware update once Dolby have eliminated the bug.

  2. Update: There is now a new Firmware Patch available that supposedly addresses the issue where the first second of each track is missed during CD/Music playback. The fix works by changing how the Processor treats the ‘gap’ between tracks when a 44.1Khz signal track is detected and not trying to re-negotiate the signal.

    My understanding is that this will not sure the missing second of audio from the first track played or if skipping back and forth between tracks.

    The firmware pacth also needs to be done offsite, so you will need to return the unit to ADA or your Distributor.

    As soon as I have the opportunity, I will get mine updated and report on it.


  3. Update: Please note recent information suggests not all 3D implimentations are supported, so please check with your dealer before purchasing hardware.

  4. Great review Adam, well it must be as I’ve read it about 4 times! To date I think this is still the only proper review I can find on the net.

    Re: 3-D support. Officially this is a HDMI 1.3 processor, but in theory it should be able to pass through 3-D video as there is no video processing inside. However, issues between players and TV means that there can be HDMI sync issues (or something like that). It’s nothing to do with the Ada, but the end result is a blank screen and no audio.

    No biggie though…most of the 3-D content in the UK is via Sky, otherwise there are BD players with dual HDMI outputs, otherwise it’s a case of connecting direct from the player to the display, and either optical or co-ax to the processor (no lossless audio though).

    Anyway, enough rambling…getting used to my Ada now and so far it’s been a revelation and shock horror…I’ve started listening to music again…

  5. Thanks for the Feedback Smurfin, I think 3D support depends very much on the implimentation. I know ADA follow the HDMI spec to the letter and nnot all hardware manufacturers do, meaning some things are completely compatable. Hopefully you will be able to provide more feedback as I am sure you will be getting more 3D kit in the future!

  6. I have updated the Review again to add some ADA Suite 7.1 HD IR codes to the appendix:

    They haven’t all been tested but hopefully will prove useful to someone.


    Adam 🙂

  7. Very well writed review, i’ve the ADA Suite 7.1 standard (with two ada amps, PF-2501 + PTM-6150).

    One question, i would be very grateful if you can send to me both HD Suite v4 and PEQv2.0 software!, Thanks!

  8. Hi Max,

    You should be able to obtain this software from your dealer and it is worth doing that if you can because it does provide you with the tools to completely mess up your setup. Without your dealer supporting you, you may have big problems getting everything working again if the wosrt happens.

    Also different firmware versions require different versions of the software.

    Adam 🙂

  9. Adam

    Do you know when the new firmware is coming out?

  10. Hi Smurfin,

    I haven’t heard anything yet but as ADA are at CES presently and I imagine it has been their focus lately I haven’t been pestering them yet.

    Once the show is over I’ll see what I can find out.

    I noticed some reports on ADA and their upcoming Pre/Pro and TEQ products, they sound very exciting if not very expensive!


    Adam 🙂

  11. Hi Chaps,

    I have a little news about the new firmware.

    ADA have sorted the outstanding issues but wont be releasing the new firmware until it has been field tested on their new HDMI 1.4 Processors which should be available ‘soon’.

    ADA don’t want to commit to a timescale on the HDMI 1.4 Processor release or the firmware update but I suspect early Q2 2011 is realistic.

    Fingers crossed!

    Adam 🙂

  12. Thanks for the review, certainly whetted my appetite. Saving those pennies…

    A question on the audio capabilities – can it provide bass management for analog sources? I still have (and use) a turntable.

    If it can do BM for analog sources, do you know if it does it strictly in analog domain, or first an A-D conversion?

  13. Hi,

    I am pretty sure it does apply bass maangeemnt to analogue sources but I think it does the whole AD/DA conversion first. I know this isn’t ideal but it all depends if the affect is detrimental at the end of the day 🙂

    I’ll check though and get back to you.


  14. Thanks, Adam, appreciate that. I read through the manual, but it did not make any explicit statements (which leads me to suspect you are right about A-D conversion, else they missed a marketing trick!).

  15. Ok, I can confirm the above is true but bear in mind you can also create unique bass management and PEQ per input, so there is a lot of flexibility available. AD/DA is not such a big deal nowadays anayway.


  16. Excellent review covering all aspects of a great processor

  17. Hi Adam I gather Angeleyes ‘;) what a great website great insight into the ADA and oh boy I want one now lol

    How is music for you now? And this thing must use some very VERY good DAC’s and so on, a Blu-Ray music concert that if you haven’t got you should have is (Hit Man, David Foster & Friends) have to say a lot of it is a bit cheesy but there are some magic moments in there 🙂

    Best Regards

  18. Hi Ashmanuk,

    nice to see you over here.

    I have heard some of that Blu-Ray and have the second one (The Hitman Returns) although I am not sure it is as good. Well mastered though!

    Adam 🙂

  19. Hi Adam,

    NaTT here from the forums. Do you still have the rack mount face plate?
    I’m going to be rack mounting mine soon and have the non rack mount one at the moment….

  20. Hi NaTT,

    I am afraid not, I changed mine for a non-rack mount version. If you contact Genesis Technologies they should be able to order you a replacement and I think it is a simple swap you can do yourself.

    Adam 🙂

  21. Great overview thanks. One thing – the links to the manuals are dead, as is the link on the ADA website to the overview video.

    Are these available anywhere else please (or could you send them?)

    Many thanks, Baz

  22. Hi Baz,

    I have replaced the dead links with the latest HDMI 1.4 Manual and am now hosting the video on my server.


    Adam 🙂

  23. Hi, my unit don’t work well with IR codes, i’ve the same issue with the old Suite 7.1 solved changing an internal jumper to the lowest baudrate (i had a diagrams from Ada).
    How for the HD version?

  24. Hi Max,

    It has been a while since I owned my ADA, so I can’t be of much help I am afraid. I don’t know anything about an internal jumper, sorry.


  25. Just one question, may you send me your nevo s70 backup?

  26. I use a Q50 and only have backups for IP control. IR uses different codes IIRC.


  27. I’m searching a backup for using s70 with ip control too, may you send me your file?
    I’m really appreciate, Thanks.

  28. Email sent, hope it helps.

    Adam 🙂
