I have a 2.1 system I listen to from my computer, and while it sounds good I would like to get some bass management into it. The sub has crossover so I can make that play the frequencies I want, but the monitors get full signal, which I would like to avoid to make them able to focus on higher frequencies.
Strangely enough, finding some neat hardware that solves this is very hard (it’s not like I am alone with this problem). A USB DAC with bass management is also non-existent, at least in my price range.
If anyone know of good and not terrible expensive solution for this, please let me know.
But then I got a little creative. I have an old DragonFly DAC (the 1.2 version) and the newer and improved DragonFly Red. So here is what I tried:
Connect both DACs to computer, and add them in Roon as 2 zones
Group the zones in Roon, so they get the same digital stream from Roon
Connect one DAC to the monitors, and another to the sub.
Add highpass filter to the sub-DAC in Parametric EQ, at around 80 Hz and 24 dB/octave
Add lowpass filter to the monitor-DAC in Parametric EQ, at around 80 Hz and 24 dB/octave
And it works very well, and as far as I can tell is an optimal crossover solution from an audio-standpoint (this assumes that the timings in the DAC is 100% similar though). However, my DAC get its volume from Windows, so controlling volume from Windows don’t seem possible. So I had to choose DSP volume and change volume in Roon.
If Roon could add a “link volume” between Zones, and send Windows volume information to both DACs, this solution would be perfect
@allo.comAllo.com have the Piano 2.1 DAC that will probably do what you need but I have yet to see some specific set of instructions how to go about the splitting of the bass filtered output to one or 2 subs.
Read a little more, don’t that need Rasperry Pi? I don’t have that (but if the need is great I guess I could get one). I play directly from my computer through USB -> Dragon Red USB DAC -> 2.1 speakers
Does that mean I can use it directly from USB, and handle bass management? Can it handle FIR filters as well? That would be awesome, because then I would get room correction working on all audio and not just from Roon.
Any comparisons in sound quality compared to what I have now, which is DragonFly Red?
Cool solution using the 2 DACs - I wonder too if clock sync is an issue that you can hear?
You could look at this option from miniDSP which is a DAC and DSP in one.
Cheers, and it supports REW which means it can handle the room correction as well. Anyone know the quality of the DAC in those? Will they take volume information from Windows without using the Windows-mixer (i.e. in exclusive mode)?
I can not hear any clock problem in my 2-DAC hack, but that does not mean it does not exist. To be safe, it would be best to use identical DACs, and even then its no guarantee,
Yes RPi is needed for the Allo piano to function…not for a USB connection but it’s a cheap setup if you don’t mind a little diy
Minidsp 2x4hd would mayb work better if you like the idea of rew and whatnot but I think the spec tops out at 24/96 or at best 24/192. It’s also has different plugins that you need to decide on and it’s boxed etc. an added plus is an analogue input that can be used too.
I just found this: Rolls SX45 but as always with devices like that its hard to know what effect they have on the sound quality. But if it works good, its an alternative. I would like a sharper falloff though.
I use active speakers and sub connected directly to an USB DAC from computer (my home office), and cluttering the desk with a receiver feels unnecessary.
The miniDPS solution is great, but I already have a DAC (DragonFly Red) and then I have to replace that, and while miniDSP has bass management (and more) I don’t want to sacrifice overall music quality and I feel a little suspicious about DIYsh solutions and music quality (but maybe I am wrong).
If I know I can upgrade my DAC and get 2.1 support that would be ok, for example the Parasound P5, but $1000 feels a little step. For that price, I would rather upgrade my monitors to better sounding ones with a high pass filter.
Wouldn’t the HT receiver convert the output from the DAC back into digital to do the 2.1 split? If so, any benefit from a decent high-quality USB DAC would be lost.
