I would say one thing about your words above RE: the target audience.
If you follow the the couple of different mini-dsp threads that are active on just this board, you will see questions being asked that clearly prove a large portion of the buyers and potential buyers are beginners and have a lot of basic questions when it comes to eq, dsp, signal chain, even balanced cable questions.
How are they to know about input clipping and proper headroom in the dsp if they don't even know how to make audio cables, or what Q does, etc... ?? A lot I see don't even have the desire to learn about the cables they just want to hook it up, run REW, and auto eq to be done.
And .....that goes for me too. I'm just as new to a lot of this stuff. I just happen to have OCD and the need to know how stuff works.
Reading through this when searching for information on the MiniDSP, and for all the functionality of the product, the issues about voltage and cabling are the single biggest reason I haven't bought one yet. Let me explain...
I have a Denon 4311 AVR with MultiEQ XT32 and Audyssey Pro.. My system has Mythos ST mains, a CS-8080 HD center, Gem XL surrounds, and two HSU ULS-15 subs. The mains and center are powered, with a woofer section that you can run either as LFE input as a faux sub, or you can run these speakers as a single speaker, with the signal carried on speaker wire. All my LFE/sub connections are currently unbalanced RCA types.
However, I'm toying, based on the suggestion of some guys on my REW/HDMI thread, with going the Geddes "more bass, even with less capable subs, is better" route, and using the Mythos ST LFE inputs, the CS-8080 LFE input, and my two real subs in some manner to ultimately get a better overall bass response with frequency response and more importantly bass decay rates.
Having said that, the MiniDSP 10x10 in a box, and the 10x10 plug-in, would be perfect. I could put the two real subs and the three woofers on LFE, set separate levels, and matrix them into one or more sub channels as output (which I can always run on a Y-adaptor as a single output from my AVR if I want). That way I can manage delay and levels within the MiniDSP for the individual (or grouped) subs, experiment with different high shelf filters for the channel or channels input from my powered speakers (example: maybe I use a steeper high shelf filter to minimize distortion from my powered center, which only reaches to about 40 Hz, than my powered mains, which can reach more like 25 to 30 Hz), even set some crude house curves on the final output once Audyssey is done. Plus the MiniDSP has multiple presets, which facilitates experimentation.
In a way I'd have more flexible functionality than from either Sub HT EQ, where you can set distance and trim for only two independent sub channels and then EQ them as one (vs. a more interesting approach with an AntiMode or MiniDSP for > 2 subs before you do the final "EQ as one"), or the Audyssey Pro Kit, with its +/- 3 db Target Curve Editor.
But...I get bogged down about the need for XLR cables, creating your own Phoenix cables, and the issues with what voltage to set. For me, the naïve thinking is that since all my inputs are RCA and unbalanced, there's no issue, and connect away on the units unbalanced input/output. Yet, I see a lot of advice that you should go balanced, and tweak voltage for your own situation. And I don't want to blow out my subs with gear designed for pro audio/DIY enthusiasts rather than home audio consumers.
Reading all that, I don't feel comfortable buying a MiniDSP unless I was a lot more DIY than I am with voltage boards and creating my own cables, which I could care less about with my focus on the unit's versatility. Is there really a straight forward answer to this, like you only need to play with voltage if you have some high-powered Emotiva amp, XLR inputs, and DIY stuff? And that as a consumer, there's no risk in taking the plunge as long as I don't start running REW sweeps at 95 db or something?Edited by sdrucker - 11/18/13 at 3:57pm
