Behringer Micromix MX400 Ultra Low-Noise 4-Channel Line Mixer

The Behringer Micromix MX400 Ultra Low-Noise 4-Channel Line Mixer yields the highest sonic quality at all output levels, boasting ultra low-noise 4580 operational amplifiers for outstanding audio performance with input Level control for each channel. Expanding on the capabilities of standard-size mixers is where the MX400 does extremely well, as a sub-mixer. If you are running short on available channels on your "big" mixer and need to bring the output of three different keyboards into your mix, you can simply connect them to the MX400, work out the keyboard mix and connect the MX400's output to a single input on your main mixer.
