I am not sure of the bug details. All I know is that thru conversing with Carl and him to the datasat team they isolated an hdmi dd2.0 bug.

I have not used the inbuilt rta. I find it easier to use REW rather than flicking between rs20i menus.

My main issue with the inbuilt rta is that you can not provide a mic cal file for the unit so as to offset the frequency response of the mic you are using.

I too am trying to use an external RTA. How did you connect using REW?(I mean what connection did you use) Can you play a sweep to a group of channels? Like for instance , run a sweep for all the sub channels?

Well I don't have my RS20i yet but hope to in the next few weeks... My question is about near-term planning though - I will be using using either an OPPO 95 or 105 as the main source for bluray, and am wondering if there is a major benefit to going with analog audio into the datasat... I remember reading somewhere that HDMI limits audio bandwith to 48kHz no matter what is on the disc, but analog signals are passed unmolested.


Is that the case? Will the RS20i care prefer one signal type over another? In other words, is there a practical upside to using analog over HDMI? I've researched this on and off, and just haven't gotten a clear consensus yet, especially with a high-end piece like the Datasat


By the way Dave, thanks for taking the initiative to start this thread!

That's how I have mine set, Dave. Nice and simple. But I first have them set individually to apply their own eqs.

And datasat have found a bug with dd2.0 stream from hdmi. So that should be fixed shortly.

Not quite sure what you mean by how you apply individual eqs to copied speakers.


I thought when you copy a speaker you also copy its eq settings. If you copy speaker 4 to speakers 10,11, and 12, the latter three will all have the eq (and delays, levels, etc) of speaker 1.

The RTA in the RS20i is only 1/3 octave graphic on a 1"x5" screen. I do not think you could observe the effects of mic cal file with this resolution and display. You could always look at the mic cal file and see what the corrections are. With a good mic they are generally small from my experience.

Dave, I think you are confusing some terms. A Real TIme Analyzer measures the signal that is coming out of the speaker. The sound/source can be anything, music, test tone, sweep, etc. For an REW RTA you just select RTA within REW (mic connected to computer which is running REW). The test tone would be the pink noise signal from the RS20i, which you can output in any combination of speakers. The REW RTA has much more resolution than the RS20i RTA plus it can be saved etc. The RS20i and REW are not connected to each other. The RS20i provides the test signal, REW RTA measures it.


To do a sweep from REW to the RS20i is more complicated. You would have to connect the output from REW to a DB25 (for multichannel) input. You would then physicially move the cable from channel to to channel. To do 8 channels simultaneously you would have to split the REW signal into 8 cables.

HDMI can go up to 192kHz. It is only if you try to output a digital signal from the RS20i that it will be downsampled to 48kHz.

Wrong


You simply need to connect to a single channel of the analogue inputs then using the output routing table you can quickly send the input to output or combination of outputs. No additional cables or changes of connector required. Very simple solution.


I am sure that you can do a similar trick in the EQ page but this way is easiest for me.

Dave. I don't think that sub layout is necessarily what you were after. Dan explained exactly how to get a mono feed to multiple subs and this is how we prefer to configure them for movie playback.

As Neil says, I just run a single output from my tascam us122mkii to left in on stereo 1 input. I can then send this to all channels via stereo routing. Except I can not send to my rears as, previously mentioned, I can not get my rears to fire on a stereo input. Most odd.


But for using rta I just use the internal tones of the rs20i and use rta on REW to measure and then I adjust accordingly.


In audio levels you have the option of either running pink noise thru a single channel or if you tick multichannel pink noise you can then select each channel you wish to play pink noise from simultaniously.


And re sub calibration. I listen to music using the subs as left and right so I calibrate them seperately. Then for movies I sum them to mono and run another eq for that.


It is a shame that one can not sum 2 sub channels and keep their independent eqs. Although I believe Dirac filters will allow this. But Neil will know for sure on that matter.

OK, so then is it even worth the acrobatics to run analog audio into the Datasat then? There seems to be a lot of hype for analog audio to be the darling of high end audio

I thought as much Neil. Thanks for clarifying that.


And I would not bother with analogue out from blu ray. Even the dacs and processing was better on my old Rotel 1570 compared to oppo 95. So IMO, running analogue ins would be a waste of the processing power of the rs20i.

I am a little confused with the suggestions around setting up subwoofers.


I have two subwoofers, one each next to my L&R speakers.


For movie listening (my predominant purpose with the RS20i) I think the suggestion is to have both subwoofer channels on channel 4 as per JapanDave's post and then EQ'd them as one subwoofer (I assume you set up bass management as a mono subwoofer). Is that correct?


At the moment I have set my subwoofers up as dual subwoofers (L&R) using bass management and assigning them to channel 4 and channel 9 as seperate channels and have EQ'd each as separate channels.


This is getting interesting!

But, would enable you to get a sweep of multiple channels at once?

I don't think Dan was able to get Mono to all subs when he had the unit. How did you do it? And I can understand how doing what I did would have all those channels EQ'ed under one channel.

How did you connect the cable to your PC and what did you use? Also can you show screen shots or a few pics of how you have the RS20i set to feed the stereo input?

Yes, that is correct. When you have your two subs on that channel (4) and have base management on mono, it will feed the channel 4 signal to both subs. You could feed as many subs you want that same signal via my screen shot.


We needed this thread a long time ago.

Thanks JapanDave for your advice and as noted by others, in commencing this thread. I will rerun Dirac on the weekend setting my subs as suggested - for those that have tried the sub options available does this appear to be the preferred/best arrangement for listening to movies (it sounds a bit like the SubEQ version for Datasat users)?

It is my understanding that if you route the input of channel 1 to the output of channel 2 that channel 2 will have the eq etc of channel 1.

I don't have a unit in front of me but 99.9% sure the parametric and third octave EQ maps to an output hence it does not matter what input you direct to the output. This applies after Dirac in the processing chain and Dirac for certain IS mapped to the input channel driving however many outputs.


I had a good slide that showed the processing order and will try and dig it out.

Please see Fig 68 on page 88 of the current on-line manual:

http://www.datasatdigital.com/docs/archive/TM-H529_V1.00_RS20i_User_Guide.pdf

4.3.8.4.1. Signal flow


From a user perspective, the channel mapping occurs near the last stage of the signal

processing. Only high pass and low pass filters are applied after the signal routing occurs.

This is illustrated in the diagram below. [can't copy diagram]



If I understand this correctly the only controls you have available on Channel 2 when copied from Channel 1 are high and low pass filters. All other controls for Channel 2 are set in Channel 1.

Hi Roger,

That sounds exactly like an idea that's been floating around in my head. Where in your signal chain do you make these adjustments ? I guess it's in your processor and that you have memories to allow simple switching ? Don't think my DHC-9.9 can do this.
Maybe an iRule macro could do it ? Looks like a bit of work is required !

Cheers,

Peter, I have just seen that you can have up 20 presets that you can store things like delays , EQ settings etc,etc.
