  1. The bit transparency check for the Kii Three requires a special wav test file (mono 44.1khz 24bit) from Kii Audio which needs to be played. Only then it will say YES if everything is OK. If I remember correctly, the file needs to be played unaltered, which means no attenuation by a SW player, otherwise the result will be NO. It's an internal test for the Kii Three audio-chain to be fully bit transparent and not corrupted.
  2. Hi input username here. It's a bit difficult to diagnose remotely, but I guess you have read the REW manual regarding set-up (although the screenshots may differ) and your REW preferences are set showing the following setings: Output Device: Kii Control, Output: SPEAKER and Input Device: Umik-1 Gain: 18db, Input: MICROPHONE (see example screenshot taken from one of my measurements). At least that were my preferences settings when I did my set-up and measurements. So I guess it should look similar for you. I started exactly the same way as you from scratch with a Umik-1 and REW but everything worked out just fine. I was running it on a MAC though. Regarding sound only coming from one speaker: did you verify the settings for the measurements: in REW you can make choices for L, R, L+R at several locations. So maybe one setting is not set to L+R somewhere. I don't have access to the Kiis and the Umik at the moment, otherwise I could try to be a bit more specific...
  3. Sure, this can be fun and it would be interesting to know, if it actually does make a difference. I myself though am currently happy with the results the Kii delivers with its own SRC processes but may be tempted if experiences here will sound promising Below some statements I found from Bruno Putzeys on SRC and his implementation in the Kii Three: "In terms of sample-rate conversion, it's worth mentioning that we designed our own software-based SRC because we wanted full control over jitter attenuation and impulse response. I found that filters with a relatively broad transition band (i.e. short impulse response) and extremely low in-band ripple are the most transparent. You've probably noticed that even RedBook comes rather close to high res. This is the underlying reason. Using super-high sample rates is a poor substitute for correct filter design. All data types with the Three end up converted to the same internal format but each input rate has filters designed specifically for it. The only 'disadvantage' of this is that you can't varispeed the digital signal but I guess it's not really something folks do anyway. Our internal DSP processing is 40-bit floating point. This means that no resolution is lost by digital attenuation. The connection to the DAC is fixed point but the output is fully dithered. People still don't believe it but dithering truly turns quantisation errors into pure noise that's indistinguishable from ordinary analogue noise. An item we're quite proud of is our IIR filter structure. It's completely different from the normal 'direct form' implementation that, AFAIK, literally everyone else uses. ..." http://6moons.com/audioreviews2/kii/5.html
  4. Regarding this rather unusual internal sampling rate of 93.75 kHz I found some small additional info here: https://www.audiosciencereview.com/forum/index.php?threads/why-93-75-khz-sampling-rate.4309/
  5. ... and besides the Kii then re-samples every signal to an internal sampling rate of 93.75 kHz....(same as the Grimm LS1 I think....) (https://kiiaudio.com/media/GENERAL/docs/reviews/kii3hfn818lowrez.pdf)
  6. Mazza, you are correct. I also mentioned this once to Kii to have both in sync for the naming to avoid potential confusion. The tool (installer) itself I think doesn't change that much (apart maybe from some under the hood things), so that a renaming according to the leading part of the FW (which is for KC) would help a lot. (And I suppose there would never be an individual release of the tool without any changes for the FW components it includes that really would justify an individual versioning)
  7. Hi Cazzesman, yes, this is the most recent version. Also see this post (and following) on the previous page here regarding fixes: https://audiophilestyle.com/forums/topic/34992-kii-three-my-impressions-and-pro-reviews/page/56/?tab=comments#comment-1026223 Best, rubysea
  8. Which wise source told you so? Since 5-FEB there doesn't seem to be any newer FW available as currently posted at Kii's download location (version 1.4 of the update-tool) https://kiiaudio.helpdocsonline.com/update-tool
  9. New firmware update is just out. From the website: This download of the update tool contains the most current firmware versions: Kii Control: 2.4 K3 PIC: 3.9 K3 DSP: 4.9 BXT: 0.6 Fixes (from inofficial changelog): - Fixed bug in analogue input level detection - Bluetooth device now presents itself as a hifi device instead of a headset - Slave settings will be copied in KC menu from master for linked settings like boundary
  10. Yes, using presets is the best way when using different sources, especially as for TV you will need to set the preset to minimum latency for better lip-syn accuracy. However, if one preset is fed by a EQ-corrected source (eg from Audiolense via Roon) only that preset will profit from the correction. The others won't. And setting up any of the Kii advanced filter EQ settings in this scenario would then correct the Roon fed preset/ source twice, as the Kii advanced filters are universally applied to all presets
  11. @input username here ad 3/3,5: yes, this is what you basically need to do if you want to use the new advanced filters of the Kii (and not other SW/HW). You measure in REW and then experiment with the Kii filters. For my bad room mode I tried a notch filter first but then opted for a PEQ prop. Q setting. This all involved a lot of measurements and filter re-adjustments. Otherwise you bypass the Kii filters and let REW (or ohter measuring software) calculate the filter settings (via txt file) for eg. ohter MiniDSP Hardware/Software which then does the filtering and passes on a filtered/corrected audio input signal to the Kiis. ad 4: What you can do here is also a matter of experimentation. The boundary setting I took for my right speaker I similarly could have achieved with a low shelf filter. I assume the boundary filter setting basicly is a low shelf filter. OK, the way of measuring, manually adjusting the filters in Kii, re-measuring, readjusting filters, etc, etc. is tedious, but will lead to some results without further need to invest more money (but its fun and you can learn quite a bit). If you already have other SW/HW in place, that can calculate the best stettings automatically or import such calculations, then there is no need to utilize the new filters of the Kii
  12. When the EQ filters were first introduced during beta FW end of September last year I also didn't know too much about them. But at the time I was already interested in room correction methods (via other HW/SW) and was very glad to find the possibility to tackle that topic then without any further "big" initial investment. What each filter does is fairly easy to research on the web. To try them out of course you would need to "see" and hear what they can do. So here I took a rather small investment for a MiniDSP UMIK-1 microphone and a mic stand and downloaded the REW software to start measuring the Kiis in my room. The REW manual is a really good starting point for initial steps of room correction. In sum it says: "The best we can do is deal with the broad, shallow dips and work on the peaks" and " We can use the equaliser to help tame the peaks, and the lower down they occur, the better the results we are likely to get". If you stick to these statements for the beginning, you already can make huge steps. Like fpalm69 stated above, I also had a similar strong room mode around 40db (>20db!) that I did tame initially, which was already a big step forward. Now I use a combination for a boundary setting for one speaker, and individual EQ settings for each speaker (Advanced Filters >> Link all with master: No). So you need to take a lot of measurements and a lot of experimenting (when you are new to this topic like me), but this can yield rewarding results and you will enjoy the music even more 🙂 And the topic of a house/target curve I haven't even touched because for that I would like to consider some other room treatments first like absorbers/ diffusors (which is on my agenda)
  13. completely agree with @firedog Besides, what should these sonic changes be, for a speaker that is designed to be a neutral monitor and whose overall characteristic (eg. time alignment, cardioid radiation pattern, etc.) is fully matched for the individual drivers used and so stored as inherent DSP setting(s). Why should they be changed by Kii? We as users/ listeners can do this now with the new EQ settings, if we haven't done so already with other software/hardware.
  14. hmm, that seems to be very strange, that you even can't switch them off manually. For me that at least works. Have you tried to unplug the KC and reset the speakers or even completely unpluged/restart everything?
  15. @Yellowspider regarding auto turn-off: it could be possible that for the XLR the auto turn-off does not work because the Kii's still might receive a signal. In case you have connected an phono preamp to them there might still be a signal "leakage" in case the preamp is not switched off. However, there actually might be a problem with the current FW version. his morning I found my Kii's still powered on from last night (and I was using the toslink input), but the previous times I used them, they auto powerd off (toslink and spdif).
