Hey there --
I am looking for some help spec'ing out my MiniDSP system for my 2-way OB speakers. The OB are built using Alpha 15a speakers for the woofer and 8" wild burro betsys for the full range.
Build info is here:
http://www.diyaudio.com/forums/multi-way/229319-2-way-ob-betsy-k-alpha-15a-minidsp-active-cross-build-log-measure-log.html
I currently have a MiniDSP 2x4 and my system flow is as follows
Laptop -> ApogeeDUET => MiniDSP 2x4 -> Battery-powered Class-D for Betsy and Rotel RB1050b for Alpha 15a.
The main concern I have is the unnecessary A/D and D/A conversion that is happening between the Duet and the MiniDSP 2x4.
I am at a loss at the best way to move forward with my system. I am thinking building a more cohesive block-based system might be the best option.
My class-d amp is powered by a 12-volt 7 Ah SLA battery, which could easily power the miniDSP and several DACs. Or I could get the NanoDigi 2x8 and run S/PDIF in and then 2x external S/PDIF out before the amps. But still that would not be a clean setup, and I don't want two big external DACs needing power supplies etc.
I'd love a single box that has an optical in that I can run the output of a yet-to-be-purchased airport express into. The optical signal is feed to the miniDSP, which performs the crossover and EQ needed, and then to 4-channels of battery-powered DAC. The HF would be powered by the battery-powered Class-D inside this chassis, and the LF would be RCA outputs to wire up the External power amp.
I'd love a single volume control. It looks like some of the stuff at TwistedPear audio would do what I need, but I don't know where to start. I just want to avoid buying a lot of stuff that won't work or can't do what I need.
Any help would be much appreciated, sorry for the brain-dump but I am just trying to find the best way forward...
