Dual XLR/3.5mm/6.35mm Audio Preamp

Used this for a concert I filmed… awesome!!

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.

This unit fills the void for me, because my video camera does not have Professional XLR Audio Inputs. This unit receives 1/4" , XLR, and 3.5mm Audio cable connections. What impresses me the most is that it can deliver Phantom Power to shotgun microphones. The one drawback for me with this unit is that it has a 9 volt battery powering it and I do not see any battery indicator to tell you how much power is left in the battery. However this unit was not made for the way I'm mounting it. I believe it was made to attach to a mic stand or belt on a person. I chose to modify it to mount on my camera. So I can not ding them for this. The unit could use a little more gain level, but does suffice for my professional use. You get a louder noise floor if you try and turn the gain up past the 12 O'clock position. All in All this unit is a God Send for me and my camera rig.

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

Title says it all. Maybe this product is not working correctly. But I needed double channels for an iPhone X, using the original iphone USB TRRS input adapter. For some reason the gain from the one channel has an effect on the other channel. I've spent 4+ hours trying to debug this device and at this point I've realized that it's just not designed for an iPhone at all. Instead what I am forced to do is get a passive XLR mixer and send that mixed signal through to a device that is specifically designed for the iPhone using the lightning port. This is sad because I really wanted this device to work on iphone so that I could use it also with the android phone my gf uses to record. Unfortunatly it seems that this is yet another dual mic system that fails to work properly on the iphone, so I will be returning it.

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 power Additionally, 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.

Works good, easy to use, sound is great, worked with my two XLR mics and my aux Jack mic, worth the money if you really need it. The only thing is it won't work for taking videos, only audios. Great for if you want to make music or if you want to do an audio podcast. But if you're looking for something to do videos or lives with, don't waste your money. Battery life is good, jus got some basic 9v and it didn't die on me once. I returned it because I ended up realizing I don't need it. Still a good product if you really need it tho. PS. You might have trouble opening and closing the battery socket, it's tough.

Instructions aren't clear if this is for acoustic guitars with pick ups only or also electric, the pre amp has too little gain for my dynamic mic or my pick up equipped ukulele and I could not get my electric instruments through it at all, even when through an amp. I don't understand the general secrecy in the industry about what jacks they have and need to connect. It may have worked but every version of adapter I tried did not work especially with adapters to Apple lightning and don't even get me started on the Gopro mic adapter... I don't understand why every jack we buy isn't clearly labeled so we can know what the right adapters that are needed for every instance. This is not just with this, it is an industry wide problem. We can see that this is a trrs jack, but there are two standards, the bottom two rings can be mic/ground or ground/mic. According to one source the black insulators means it is the less common China version. Maybe. If so another adapter is needed to reverse the ground/mic ring configuration. Because the preamps are so weak for the money I give up finding out and sent it back. I discovered my Zoom 4hn does a better job as a pass through device, it even has combo xlr/1/4" mic inputs for the dynamic instrument mic I am trying to set up. Also discovered that running the electric instruments through my Line 6 Sonic Port into the iPad and on to the camera gives a much superior and manipulable feed to my camera. So much for a small portable all in one package that I can use on my iPhone 7 that does not have a 3.5 jack though. I may have to give up on using the dynamic intrument cardoid mic with the phone. Which was the primary purpose of this device for me.

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.

ノイズが少ないです。応用範囲が広く手元でコントロール出来るので便利です。

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.

９Ｖの四角い乾電池を使うのですが、海外のと日本の電池の規格が違うみたいで、電池を入れるとフタが閉まりません。テープやゴムで押さえて使ってます。 また、ボリュームのツマミがすぐに抜けてしまうので、カバンとかに入れる時に失くさないように注意が必要です。 2つのライン入力があるので、製品としては気にいってます。

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。
