Great value

This little unit is perfect for the mix phase of production. All the controls necessary to speed up work flow saving you time in the studio.

This is truly a passive monitor controller in that it does not add any sound-changing audio to your signal (also verified due to the fact it generates no heat so I know there's no significant amplification or change happening to the signal). It is also very well-built, easy to use, and well-designed. I have two pair of monitors (Tannoy and Sonnodyne) and able to A-B my mixes through either (or both) at a push of a button and the top A and B volume adjustment screws lets me get the two monitor pairs matched in terms of volume so it's an honest A/B comparison. The mono switch is vital for stereo sound field checking, and the dim switch makes for instant adjustable muting of the volume so you can talk to the person next to you without changing your volume. I have not used the subwoofer functionality because I do not have or need them but nice to know its there if someday I do. Functionally, the Radial MC3 gives you what you need and nothing else to bulk it up and I was surprised how small it is but very happy it is this small so it doesn't take up much room on my desktop. Love it!

Perfect for my needs

Very straightforward and classy... No unnecessary bells and whistles. Perfect for the project studio with two sets of monitors. I wish the aux output was direct and not post headphone amp volume pot.

The only Radial product I can't stand by

I had deep problems with this unit: db loss, volume pot doesn't completely silence in coming signals, A/B cross talk, and unexplained drops in signal. Build like a tank on the outside, but more of gremlin inside I am afraid.

Nice but some irritating things to consider

As a commercial studio, we look for the very helpful products that are reasonably priced. This unit is ok but not necessarily stellar. Advantages: -Ability to tweak-lock the A/B and Sub volumes for easy A/B/S switching on mix sessions. -Lighted LEDs for quick glance when A/B'ing phase issues. -Ability to quickly turn headphones on/off. Disadvantages: -Volume knob is quite small compared to what an engineer really needs...a large radius knob to be able to attenuate with better control. -REALLY BAD: After some use, the volume attenuator introduces noise at lower volumes when adjusting. Much like a corroded volume knob on a guitar amplifier, etc. (maybe a bad choice of conductor metal?) -Headphone volume is a chain from the main volume knob. Would be better if the headphone was simply a split from the DI.

Sweetwater Advice

Carson McClain

There is only one "go-to" piece if you do not have the budget for a Dangerous Music Source or Dbox and that is the Radial MC3. Canadian built, quality components, easy to use, and if you do end up outgrowing it, it can always be used somewhere else in your home or studio. I highly recommend every Radial product out there and I'm very happy they've finally built a monitor switcher.
