Great capture interface.
I’m able to record both voice and guitar in to my iPhone 6. Great tool to capture video with great audio quality.Also I edit and trim the clip in Final Cut and enhance the audio to the best quality, ready for streaming to the favorite social media channels.

Perfect
I love the device you have so many options to choose.

Doesn’t record stereo on a smartphone
They don’t tell you, but this will not record stereo on a smartphone. I tried every combination of switches and cables with no luck. I contacted Comica’s tech support and this is the answer I got.”May I know which device you connected to the AD3 for recording? If you connected a smartphone to the AD3, there is no stereo sound. Because the TRRS technology does not support stereo transmission.” It would have been nice to know this before I bought it. I returned it. I gave it 2 stars instead of 1 because it works ok recording in mono. just be aware before purchasing.

Cheapish and works mostly. When it fails, it fails hard.
I got this mixer to use for an on location live stream. It mixed two audio sources together, but it’s extremely wonky. To have two mics in both channels, you have to turn the m/s switch to m. No problem there, but channels 1 and 2 appeared to be linked together, as in order to hear channel 2, channel 1 has to be turned up as well. Super weird. Also, if it’s a long event your battery will go quick. Using Energizer max 9v, I got around 3 hrs out of it. Also when it fails it fails HARD. It started making a distorted bass tone that over powered everything. If you get this, use good batteries and make sure to change them around the 3hr mark, especially if you’re using the 48v powerAdditionally, it was not easy mounting it to a camera cage. There was no mounting hole for it, so I drilled a hole in the belt clip. This also made the battery compartment difficult to reach and change batteries in.For the money I paid, it mostly did what I asked it to. Not exceedingly well, but good enough.

This unit works great as a mini recorder and preamps, but the idea of not being able to record stereo into mobile devices was sorta buried in the specifications. Was hoping to use as a simple solution for stereo recordings on mobile, but looks as though it won’t be an option.

Works well, but the lack of AC power as an option is brutally debilitating… you’ll be eating through 9v batteries rapidly if you want to leave this set up, especially if you ever forget to switch it off. Huge oversight.

思ってた以上の性能でした。（音楽機器についてあまり知らない初心者ですので悪しからず。。）私がしたかったのは2本のマイクでスマホ（Huawei mate 20 pro）に音声を録音することです。他のミキサーだとコンデンサマイクに電源が必要だったり大きすぎたり…。ですがこちらの製品はコンパクトで電池を入れれるのでマイクに電源は必要ありません。操作もとても簡単です。マイクを2台挿し、本体のコードをスマホの変換端子に繋ぐだけで録音ができました。イヤホンの端子にイヤホンを挿すと、スマホからの音を聞くことができ、スイッチを切り替えるとマイクの音声も遅れず聞こえます。マイクのボリュームも2台それぞれ調整出来ますし、音割れもなかったです。値段が高いだけに迷っていましたが理想が詰まっていましたのでそんなの関係ねぇといった気持ちです。
