Meridian G68 and MiniDSP

I don’t think we are on the same page. The Marantz 7701 has room correction software.  The MiniDSP is being used so I can tri-amplify my main speakers.  I use filters and crossovers in the MiniDSP to accomplish this task.   I am unaware of any pre/pros that have the ability to function in this capacity. I also am unsure why there would need to be volume control outside of the Meridian G68. It contains a volume control that should adjust the digital out gains even if used in an all Meridian system. Why is the volume control on the device if it is intended to be used in a system with that control further downstream? Again, I am wondering if anyone has used a MiniDSP downstream from a digital out on a Meridian product? And what kind of success or failure they think it was?

Ah, you did not explain what you were trying to accomplish.  The Meridian G68 is a HT processor just like the Marantz 7701.  However, the G68 also has digital outputs with communication outputs.  Generally, digital outputs are full volume signals of the waveforms, so I am assuming that Meridian uses the comunications connections to have the Meridian active speaker control the volume by adjusting the amplifier gain.  This is all prioprietary from Meridian.

If you are tri-ampliying your speakers and want to improve over your Mini-DSP, I would look at high end active "pure analog" crossovers.  Here are a few:

Marchand Electronics (several models and configurations, include a tube crossover)

Thank you for the information.  I now understand this was not going to work as I had hoped 

The meridian forum, hitchikers has many informed owners and installers that I bring all my M questions to.
