Perhaps asking the obvious, but I assume that all volume control is DSP in Roon when using the straight from Coleman to amps approach?

You can do this in Roon and, while I have fooled around with it, it is not my standard operating arrangement so I cannot send you a screen shot.

@Kal Rubinson and @Steve Bruzonsky, I have a Coleman 7.1sw on the way along with a boatload of ProAudioLA DB25 cables.  For two channel sources, I have been using bass management crossovers in the Marantz AV-8802A but running those Marantz inputs on Pure Direct.  Going forward, do I need to set up the bass management in Roon if I am bypassing the Marantz entirely?  Could one of you share a screenshot of how you have it set up?

 

For the Okto dac8pro MCH, I've used the bass management functionality within Audiolense when creating convolution filters for Roon/HQP use.  Should I be able to do the same going forward bypassing the Marantz, as the Marantz MCH inputs are the 7.1 analog ones that don't apply any bass management to begin with?

Thanks for the guidance.  Cheers.  JCR

 

In my family room system, I am not doing bass management per se on the music s88 side - I use the s88 online menu to control speaker and subwoofer volume (and individual subwoofer volume controls as well), and ROON to control speaker distances. My Marantz SSP is all separate for video only  using its Audyssey for room correction, etc - but the Marantz using ROON via Airplay doesn't compare sonically to my s88 music setup.

That should be fun to hear the result, @Kal Rubinson.  I suspect we read about this experiment in a far distant Stereophile issue. :)

 

I actually have a RooDial working in my main system. It really does enable DSP Roon volume control on a Microsoft Surface Dial. I hope that will work well for the 7.1sw arrangement.


Got it that I’m on my own as to bass management in Roon. 

 

Kal, you’ve got both the S88 and the Okto? How would you describe the sonic differences?  JCR

Yes, the 7.1SW uses DB25 connectors; their a/b5.1 (which I own, bought on Ebay for $99) uses 1/4" TRS.   I like the a/b5.1 for two reasons: 1) I only have 6 channels to switch, and 2) the individual 1/4" TRS connectors allow me to use different lengths for each channel, as my rear surrounds require a 40 ft run (through in-wall smurf tubes) while the fronts only need a fraction of that.   Maybe Redco or Pro Audio LA could customize a db25 snake with different lengths too, I do not know.

 

Would the 1/4" TRS connectors on the a/b5.1 also make it easier to incorporate an input from an unbalanced source (such as an AVR's preamp outputs), or is it pretty much impossible/impractical to use an unbalance source with either of these switchers?

These two are not really suitable for unbalanced lines.  Look online for a used Zektor switch.

I may experiment with bass management in ROON at some point - right now I'm enjoying my system as is as I have it where I want it component and setup wise - again, may experiment in ROOM with its bass management etc features at some point when I recover from my current state of inherent laziness. So you can educate me hopefully. HA!

Speaker distance.

 

Is it critical to make sure the front Left, Center and Right speakers are the same distance to the MLP?  I've always used Audyssey before and assumed it took care of speaker distances (timing).  But, now, feeding my Marantz AV8805 analog in (7.1 channel in) from the S88 it occurred to me that my pre/pro is no longer adjusting timing.

 

What does everyone else do?  Just measure and make sure all three speakers are equidistant from the MLP?

 

Thanks!

If they are not all at the exact same distances (or if you are also using surround speakers which are generally not), you can set the distances in Roon or Jriver.

Thank you Kal.  I set the distances in JRiver.  Sounds much better now, especially piano.
