    Rolls MX310 reviews

    MX310 MorMics 3-Channel Mic Mixer/Combiner is rated 4.0 out of 5 by 11.
    Rated 4 out of 5 by from Works well, but subject to interference This is a really great mixing amp, well built with metal case. However, it is subject to interference from my CB Handheld radio. If I use the handheld within 2 or 3 feet, when I use the Push to talk button, a loud buzzing noise sounds on the Output of this device. It does not change if the volumes are turned up or down, so not coming in on the inputs. I do have a concern that these Rolls devices have - (negative) tip, whereas most other gear in this type of environment have + (positive) tip.� I tried to contact the manufacturer, but their website is faulty, and does not allow you to contact them as it requests confirmation email, but nowhere to type it. I am using this device, and simply removed the antenna from my handheld to reduce the signal strength and this stops the interference.

    Rated 5 out of 5 by from Great for Combining Multiple Mics into Single Output Got this unit to mix two dynamic mics (RE20 & SM7B) into a single channel pre-amp. For the price - MX310 performs this basic function perfectly, with minimal added noise. It has a toggle switch to output mic/line level. However, even at mic level it's still pretty loud - had to pad the input by 20 dB on the pre-amp to avoid clipping it.

    Rated 4 out of 5 by from Works Well but a bit oversensitive! System works quite well, even when I connect multiple mics or other sound systems to it. However may just be my system but a just a bit oversensitive in regards to grounding and therefore there is a feedback or buzz that is a bit annoying, other than that it works well if you want to extend the amount of XLR inputs in your mixer.

    Rated 1 out of 5 by from would not work as advertised This unit would not do what it was advertised to do. It said it would power a phantom powered microphone and it would not do it. The mic was rated to run with 9 to 48 volts and the mixer would not work it, so I returned it. I went with another brand after trying 3 products from this company and none of them would work.

    Rated 4 out of 5 by from Good, but requires external power Good product, surprised there aren't more that achieve this simple task. Could be greatly improved with a belt clip and perhaps simple onboard EQ. My biggest complaint is that it can't be powered by phantom further up the line from a mixer and needs to be plugged into AC to function

    Rated 5 out of 5 by from Clean sound great balance I'm running my pedal board, instrument boost, and vocal mics to a single xlr output. Mormics lets me balance the the three inputs to a single output to the mixing board. Sound is clean with plenty of range. Great little sub-mixer. B&H service is fast and never misses.
    Date published: 2018-07-31
    Rated 5 out of 5 by from Works as described As described mixes the 3 mics to one-did live recording. Sound Quality was perfect-great to have independant level of each and phantom power option is great. Well built. Easy to use.
    Date published: 2013-01-02
    Rated 5 out of 5 by from Perfect! Rugged, compact, performs its intended purpose flawlessly. Labeling for mic/line switch is confusing considering its effect. Good audio quality, good gain, nice features.
