I've had several requests for this, so here goes:
For any Emotiva UMC-200 owners who have not yet upgraded to the latest firmware version (1.52.02.47), you'll be wanting to do so at your earliest opportunity. As far as performing the update itself--good luck; if you do have any issues, you'll most likely find a solution here:
UMC-200 Update | The Emotiva Lounge
I've only had it hooked up for about an hour, but have observed some definite improvements. I haven't read any release notes so these are just anecdotal observations. Prior to the update, my UMC-200 would essentially 'reset' every time it was put into standby. On version 1.52.02.47, Input, volume, and DSP settings are all retained when the unit is switched to standby and then brought back online. I was also experiencing some other issues like intermittent loss of HDMI signal (no USB cable attached), multiple attempts required before the unit would boot, and boot loops (though these became more frequent over time, so I believe the unit was defective i.e. these issues may not be related to firmware {my unit was replaced altogether with free shipping}). EmoQ also appears to have gotten some improvements. I always have to run these calibration software programs twice to get optimal settings, this time was no different. Got some excessive distances the first time, but the second run was spot on. The center and surround channels were too quiet before--it sounds like that was corrected. It still sees my
Usher CP-6371's as 'Small', so not sure what the deal there is, but I just set them to large manually after calibrating. The new unit integrated with my BTM-1 dongle much more smoothly than the previous, as well. From what I can tell so far, it looks like all the bugs have been worked out, and this processor has now achieved its full potential.
