Echo Mic Preamp 2-Channel Audio Mixer 3.5mm/6.5mm Dual Microphone Echo Amplifier Computer Micphone Preamplifier Made of Aluminum Alloy and Treated With Surface Oxidation - Plug and Play

Awesome! I feel I am singing better now after a few practice sessions with this device. 2 adjustments for echo effects is great to get the right reverb. Usb power source is convenient, don't need another outlet used up. Priced really cheap for the quality it provides.

I never could get this unit to work with the microphones I was hoping to use. This might be the result of a mismatch between the amp and the mic, so I can't definitively blame the preamp/mixer. Electronic incompatibility can be a challenge. This might work well for others.

Works great. I'm using it with an Antlion ModMic. I would give it 5 stars if it had an off button. As it is, you can't switch it off and so the bright blue LED on it is always on. You need to unplug it if you want to turn it off. Still, very much recommended if you need a boost to your mic volume.

Perfect for the Antlion ModMic 4.0. Onboard sound needed to be 100% and boosted all the way before purchasing this mic amp. This introduced a lot of white noise.After hooking up this amp and adjusting the volume a little at a time the white noise is gone. I have more headroom for adjustments now. The Antlion ModMic 4.0 came alive with this amp and sound quality improved since the white noise went away.

Nice Product.

Really good! I wish it came with a 5V power adapter, though.

Easy, simple to use , and nice desilgn.

This worked great for our home, very small and powerful. Great for karaoke
