Received the MiniDsp 4X10 HD. A very clean unit.
I contacted Support with the units serial number, and within the hour they activated the software plugin download on my Support page for free, no charge. They've always impressed me with their online support.
The unit has internal jumpers and switches for selecting input and output gain structure.
Input unbalanced sensitivity can be set to 0.9V or 2V RMS.
Output unbalanced gain can also be set likewise to 0.9V or 2V RMS.
There are similar gain structure settings for the balanced inputs and outputs.
I'll be using the unbalanced RCA inputs and outputs.
Going to open her up and set the gain structure to it's lowest sensitivity and output gain setting. I'll get her up and running in a 2X4 configuration for the JBLs and stereo subs, and see how it compares to my ancient MiniDsp 2X4, and experiment with the gain structure.
Been listening to FM Classic Rock all day on the PL5100 S2 tuner. Spent the morning watching those DUST short scifi films on YouTube that Fred posted. Excellent and thought provoking.
