    VocoPro DA-3700 Pro reviews

    DA-3700 Pro Karaoke Mixing Amplifier is rated 4.2 out of 5 by 5.
    Rated 5 out of 5 by from Nice mixer I used the line out of the mixer amp to hook it up to the Crown xls1500 amp to JBL 112m speakers. Sounds warm and clear. Easy to use would recommend for karaoke and DJ. Love the product.

    Rated 1 out of 5 by from It has a very annoying noise. You will hear a humming sound from your speakers. I suspect that it is coming from the cheap internal effect units/circuits, since if you unplug the effect loop bars, the noise will disappear, but then there will be no sound at all. The noise is even louder if you connect a DVD/TV through the effect loop connection. The noise is clearly audible and very annoying. It destructs every thing. I know it is not expensive but for a product of this low quality, it is still overpriced.

    Rated 5 out of 5 by from Great booster to the karaoke experience My family uses the machine as a hobby. Surprisingly, the mixer increased the performances of my microphones and karaoke collection and they resang almost every songs just to test and enjoy the power. Besides not having an HDMI connection, everything about the product is a five-stars.
