It does as promised
Easy to set up and use

Quite useful and compact, but signals will compete with each other
This is very handy in a setup that utilizes multiple components, especially a tabletop synth kind of scenario. I’ve been using one in conjunction with a headphone amplifier to split the aux send of a small mixer into four different effect processors, then mix those effects back in to the tape input of the mixer. That way, I don’t have to take up any more inputs on the powered mixer, and this little mini-mixer allows me to control the levels of the effects returns going into the tape input, which is also RCA, but has no level control itself. The only drawback is that, being a passive mixer, turning one of the levels up tends to compete with the other channels. Obviously, being unpowered, there’s no boost or amplification to the signal (at least before it reaches the tape input of the powered mixer), so there’s a different kind of balancing act to the inputs on this thing. But considering I don’t have to make room for another outlet on a power strip to use this, it’s a worthwhile tradeoff.

Great bang for the buck, but don’t expect superb sound.
This little mixer is great for anything that doesn’t require you to push the mic too loud – in other words sing strongly. The mixer and accompanying mic overdrive very easily – you have to be very careful with mic placement from sound source especially if you are singing hard. What do you expect for everything you are getting with this little mixer – two wireless mics, functional USB, bluetooth, mixer and a bit of power to drive a speaker…not too shabby. If needed for some sort of simple speaking event no problem. Bluetooth works fine. All in all good bang for the buck aside from the easily overdriven mic signal when pushed.

This device is inconsistent for streaming audio via the usb port.
No doubt that this is an amazing concept, the only problem is that the USB A to cell phone USB-C function is inconsistent. I tested 3 devices for the benefit of the doubt. all three failed to perform according to the spec you may attest to in the photo provided. Please review the photo illustration a connection to a cell phone.During this process, I did receive customer support. I also want to elucidate that the USB-C streaming characteristic was designed in China by ZhuHai JieLi Technology. During this review, we will be using an galaxy S23plus, android device for testing.When a cable terminated with an OTG is connected to the galaxy 23plus phone USB-C and the other end connected to the USB-A port on the back of the device, the display should reflect “PC”. There is also a button on the back of the unit that has two positions, “mp3” and “PC”. Place the button into the “PC” position.(button out).Next, download a recording app from google play store to the galaxy S23plus. After the recording app is invoked, turn on the cordless microphone and you shall notice the peaks of your voice on the recording app. My target application was Facebook live. Remember, Facebook app must provide audio interface drivers for the connection to be established. It was also evident in my case that the recording device downloaded from the google play store provided a driver. The Aveek will control the bus and supply power.Now, as I had stated earlier, the connection between the Aveek E1 and galaxy S23plus was inconsistent. Let’s talk a moment about when a connection was successful. We would evoke Facebook live for a service, someone would always monitor Facebook live to assure there was audio. Unfortunately, audio would maintain the proper level for the audience to listen for about 20 seconds, then the level dropped. I believe that the galaxy S23 plus Facebook driver, was redirecting the connection to the internal microphone.The major confusion occurs when you are not sure if the USB-C connection which is DIGITAL mind you was using the external (USB) microphone. In the case of the recording device, if the driver does not redirect the microphone input to the USB-C port, the recording will come directly from the galaxy S23 plus internal microphone.This was part of the inconsistency that was somewhat annoying. Not know immediately if the USB connection was directing audio from the internal or external (USB) microphone.Now, why not connect this device with audio cables, because controlling audio levels is horrible. The USB-C technology is digital, and the volume level is established by design.Lastly, when testing with a recording device on the galaxy S23 Plus, there was a horrible signal /noise ratio. Signal / noise should be 5 db or more. Else, the device should provide additional frequencies, that can be changed, to deal with surrounding RF transmissions.It would be hard to describe the noise recorded on the galaxy S23Plus other than a louder than desired 200 hz frequency. The noise which was at least 5db and under would phase in and out. Mind you, this occurred on all 3 devices that I tested.I would gladly test another device from Gbest-Us if they could test the device first before they shipped it to me. I believe this mixer combines all of the required characteristics for streaming live video.By the way, a simple calculation would reveal that this in not 300 watts true RMS. It’s even larger than peak power. No one would use a 300 watts peak to peak to evaluate the power of the amplifier. let’s use this formula P = V*Ipower adaptergiven:20v @ 3 A P = 20V * 3A P = 60watts RMS. Let’s say a 4 ohm speaker P = V²/R P = 20v ^2 / 4 ohms P = 100wats RMS. Peak would be 100 / .707 P = 141watts peak to peak.Michael

Mixer passivo piuttosto solido, considerate le dimensioni più che ridotte.Il mixer è passivo, dunque non ha bisogno di alimentazone esterna.Più che un mixer, è più da considerarsi un hub: non ha un controllo output generale e non ha la possibilità di regolare le equalizzazioni interne, ma date le dimensioni sarebbe stato difficile fare diversamente.L’unica lamentela riguarda la presenza di uscite RCA, avrei preferito delle uscite jack, molto più versatili.Personalmente lo sto usando come ‘estensore’ all’esiguo numero di input della mia scheda audio, essenziale per chi non ha gli spazi necessari ad avere un mixer classico.

E’ un piccolo mixer passivo che, pertanto, non necessita di alimentazione utile a chi voglia provare a miscelare più di un canale audio per qualche motivo (registrazioni, djing ecc.). Le dimensioni sono davvero micro, in foto lo vedete poggiato sulla copertina di un Cd, per intenderci. Case in metallo e costruzione buona. Ho provato a miscelare il segnale di un giradischi e quello di un Cd player per saggiarne la bontà: con i potenziometri al massimo livello il livello di uscita è un pò più basso rispetto a quello di ingresso e la qualità audio risulta un pò più compressa e smussata. In realtà pensavo peggio, perciò, tutto sommato, è uno scatolotto che fa il suo ma senza avere pretese professionali. D’altronde per il prezzo pagato non può che essere così.
