    Shure SCM268 reviews

    SCM268 4-Channel Microphone Mixer is rated 4.7 out of 5 by 19.
    Rated 5 out of 5 by from Excelent for small purpose / reliable I work for a university setting up small and large events around campus. This little mixer's versatility is so astounding, we now have ten of them. Shure has incorporated Mic and Line level inputs for every channel making it easier to plug in units like sound from a laptop or CD player without needing a direct box. Having a Mic/Line level out allows me to adapt it to any existing system on campus without re-inventing the wheel. This is an all in one solution that I hope Shure will never stop manufacturing. We use these little mixers every day.

    Rated 5 out of 5 by from Great Mixer I am getting into the Legal Video world and needed a compact, well built mixer. The SCM268 fit the bill perfectly. It's small, has 4 XLR inputs and can power my Shure mics. I can set up quickly and depend on it to give clean sound to my recording gear.

    Rated 5 out of 5 by from Working wonderfully as expected This shure mic mixer is used in a large church with a choir. It replaces the same make and model that the church has used for years and which was dropped one too many times!

    Rated 3 out of 5 by from Works OK for the price I use this mixer for videoing conference meetings and depositions. It would be nice to have high impedance unbalanced mic output to drive cameras such as the Canon GL2.

    Rated 5 out of 5 by from Very basic & easy to use This is another great device from Shure! All the quality and ease of use I have come to expect from this brand. We rent this out as part of our house sound system in our event spaces. This allows more control for our guests in a basic an easy to use format. We have labeled the level knobs to make it easier for our guests to make on the fly changes. It gives our guests more control and eliminates headaches on our end.
