Behringer MX400, 4-Channel Line Mixer@+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 – the same chips as the ones found in its much bigger mixers. Use the MX400 as a sub-mixer for your mixer: If you are running short on available channels on your “big” mixer and need to add 3 more keyboards to your mix, just connect them to the MX400, dial-in the mix – and connect MX400’s output to a single input on your main mixer. This way you have the opportunity to mix your keyboard with the MX400, without immediately occupying several valuable mixer channels.@+@+, Compact 4-channel line mixer, Separate volume control for each channel, Low noise 4580 operational amplifier, 4x 6.3 mm Mono jack inputs, 1x 6.3 mm Mono jack outputs, Includes 12-Volt power supply, Dimensions: 46.5 x 57.2 x 103.6 mm, Weight: 190 g
