Thx for info
If I read it correctly center speaker is not necessary an it should work but if someone can confirm that this setup will play dolby 5.1 from Netflix or similar VOD services?
2xfront speakers, subwoofer, 2x WiiM lite as surround. Center - virtual speaker done by WiiM Amp Ultra.
Yes, I can play Netflix and Amazon Prime 5.1 videos with wireless surround. (However, to my experience, some 5.1 videos can't be played with surround.)
My system configuration is Amp Ultra + WiiM Sound + WiiM Sound Lite. In my home, there are almost no audio dropouts, and it works normally.
However, there are a few points to note.
Currently, automatic switching between 5.1 and 2.1 is not possible. When listening to music on the Ultra, you need to manually ungroup it via the WiiM app. Also, when watching TV, you must manually regroup and assign channels to the surround speakers again. (Installing the Ultra's beta firmware "Input Sound Profile" should allow automatic 5.1 regrouping linked to input switching.)
Since this is a bit cumbersome, it might be better to keep the 5.1 group active at all times and mute the surround speakers when listening to music.
Also, EQ and Roomfit are disabled with wireless 5.1. According to the roadmap, this functionality may be enabled in the future, but it's unclear when.
As you say even without a center speaker, Ultra creates a virtual center.
