Using REW with Eq that is all digital?

[regalma1]

I checked out both the Behringer feedback destroyers and found that they have only analog inputs and outputs. Did I miss something?

I have two other Behringer processors, the DEQ2496 and SRC2496. Neither of their analog outputs come close to the quality of the outboard DAC I am using. The SRC isn't too bad, good for the price actually. The DEQ is much worse. Based on this I would assume their other products are similar in quality.

Is there any other product that can utilize REW that can be used in an all digital mode?

Thanks,

What about something like this:

There are a couple of us on here using them for subs and mains.



Although it does say "total harmonic distortion less than 0.007% (emphasis on) 20-bit A/D and D/A convertors sampling at 44.1 kHz." I guess it is NOT pure digital.

Interesting, being Yamaha it is probably pretty good. I have one of Yamaha's newest and better AVR's and it sounds pretty good, but just not quite as good as my stand alone DAC. It lacks that last bit of airiness that I love.

I'm not sure what you're looking for.

The output signals of a DAC or processor or preamp that feeds a power amp are analog.

The output signal that is sent to a subwoofer is analog.

What would you use an equalizer for that had digital inputs and outputs?

I think he wants to use equalizer in the digital domain with his transport and let his DAC do what it was designed to do. I thought DEQ2496 is capable of that but I've heard it's not very transparent even in the digital domain (most likely due to low quality clock builtin).

You mean situate the equalizer between the source and DAC? You'd need an EQ for every source.

Or a selector switch. This is a big issue for some of us. With the rise of DSP EQ, one can either rely on what is built into AVRs and prepros which keep everything digital until the output to the power amps or one can add-on an external unit. However, because there is no standard and secure HD/MCH consumer digital interconnection, all the add-ons impose on us redundant A/D/A conversions of variable competence. (I note the NeptuneEQ ad at the top of the page as I am typing this.)

I know of no solution, yet, although even HDMI would be a possibility.

Interesting. Presumably the OP is concerned with two channel since he has the outboard DAC, so that certainly precludes use of any prepro or AVR autoEQ features as he would likely be using analog bypass to keep his pristine analog signal from the DAC untouched. This would then require a switch as you suggested. I thought the DEQ2496 had full S/PDIF digital I/O in addition to the standard analog?

I think we are drifting off of my original question. I am talking pure stereo music reproduction here. I have an AVR with built in DCR for multi-channel stuff. Unfortunately it falls a bit short of my expectations for music. So I have what is called a audio/HT hybrid system.

I feed the digital output from my PC and CD player into a DAC, then into a preamp then to my speakers and subs. The AVR analog out feeds into the HT bypass on the preamp so it can use the same outboard amps and main speakers used by the stereo. It is a pretty common setup for audiophiles who use one room for both uncompromised music listening and HT.

I would like to like to add DCR to my stereo music reproduction. At least experiment with it. Like most of us kooky audiophiles I am willing to spend money on something that may or may not help.

The REW plus BFD is very attractive, but I don't want to corrupt the signal by converting it into analog, feeding it into the BFD, converting it into digital inside the BFD to process it, then converting it back into analog. That is two extra conversion steps. Each one is going to degrade the music.

Yes, that is exactly what I had presumed. As I said in my post above, presumably you are concerned with two channel since you have the outboard DAC, so that certainly precludes use of any prepro or AVR autoEQ features as you would likely be using analog bypass to keep your pristine analog signal from the DAC untouched. I think we're on the same page.

The only access you have to the digital signal is between the source and the DAC. Is that not correct? You have a DEQ2496 that has full S/PDIF digital I/O. Why not use that? The signal never enters the analog world until it leaves your DAC.
