ケーブルが8ftすなわち2.4mで短過ぎてデイジーチェーンの意味を全くなさない。ブルートゥースマイク&スピーカのほうがマシ。

In a medium sized church, we have many groups attempting to meet partially in-person and partially online through Zoom. Enabling participants on both sides to hear and see each other has been quite a challenge. And in our socially-distanced world it is no longer possible to huddle around one conference microphone, so these daisy-chained mics are genius! The problem is getting them to work....From my experience, older laptops with separate headphone and microphone jacks do alright. They have the power to run these condenser mics. Newer laptops with a single 1/8" combination jack "TRRS" (in our case, Lenovo and Dell) do not plug-and-play. The Dell recognized a device being plugged in and I selected a microphone connection, but there was no sound. Adding a headset splitter TRRS>2xTRS did not work either. After digging deeper into the reviews, I guessed the powered jack was the problem.So, today I added a USB external sound card (you can see in my photo) which has the separate microphone and headphone jacks. It works! Ah, but before I got too excited I realized the signal was weak. I've turned up every volume setting I can find in Windows 10 and sound card software. Weak. Through Zoom, the sound is picking up evenly around the room, but it's weak. My built-in laptop mic is picking up the room (40'x40') all the way to the back better than these.My next step is to try a pre-amp or maybe one of the USB versions of this mic for the first mic connected to the laptop. I'm disappointed ECS does not offer software drivers to boost the signal or a hardware adaptor to power the mics and amplify. They seem to be well designed and constructed, with some magic signal processing in the daisy chain, but not a match for the application so many people are trying to set up.UPDATE - As I have worked with these, I learned that the more devices are daisy-chained together... the weaker the signal (volume). We were trying to use seven, which was too quiet. Using five is weak, but working for us. With fewer local participants, dropping down to four or fewer microphones improves the overall volume to Zoom.

One would think that microphones would have the ability to actually pick up sound, this is not the case with these microphones.
