Despite its ultra-compact size, the MICROMIX MX400 4-channel line mixer is really big on features! Providing the highest sonic quality at all output levels vs. the competition, the MX400 features ultra low-noise 4580 operational amplifiers for outstanding audio performance Ð the same chips as the ones found in its much bigger brethren. Expanding on the capabilities of standard-size mixers is where the MX400 works its magic, for instance when it is used as a sub-mixer. If you are running short on available channels on your ÒbigÓ mixer and need to add 3 more keyboards to your mix, just connect them to the MX400, dial-in the mix Ð and connect MX400Õs output to a single input on your main mixer. This is just one example of how the MX400 can add versatility to your current setup Ð just imagine the possibilities! ¥ Ultra-compact 4-channel line mixer ¥ Highest sonic quality even at maximum output level ¥ Input Level control for each channel ¥ Power adapter included ¥ Designed and engineered in Germany
