57
Will the sub latency control on the Ultra allow for delaying signal *to the main speakers* as well as to the sub? Many subs have onboard DSP which creates significant latency. In 2.1 systems the sub is often positioned in line with the main speakers and therefore the sub is "behind" in the time domain. Delaying the mains output solves this issue and would be a great feature not offered by many competitors.You can adjust the delays for both the main speaker and the subwoofer.
58
Can you please include items in line 58 above and also please add these?: Settable individual delays and crossover db/octave for both main speakers and sub.

64
Can it be configured to send the audio to all output channels simultaneously -- both Analog and Digital? - Please see question #12. Answer = No, except when it comes to the Sub analog output, please Question #56.We can output to all channels simultaneously with software update that we will do later.
65
QUESTION: Why is the WiiM Team so dang awesome !!! 🤩Thank you! We really appreciate our WiiM Community!!
66
IMO, a must-have feature to be able to use the line out and cast to another room simultaenously - if Wiim wants to compete in the whole house / multi room space this is required.

More specifically, the phono stage should also be bypass-able. Most people alreayd have their own phono preamps
67

10-band parametric EQ - what Frequency range is being implemented... Hopefully 20hz to 16khz. Somewhere I saw noted 50hz... that simply won't due. Manual PEQ will hopefully be 20hz to 20khz (16khz). Thank you!

92
Is 12v trigger a 2.5mm jack and can it feed 2 devices with a splitter? Also, is it constant 12v when device on or latched?
93
Would I connect it to my vintage integrated amp via an aux input or would I remove my internal pre-amp jumper and connect it at that point?
94
How many clock oscillators? (Only one or two for signals at 44khz and 48khz?)
95
