Bundle includes Yamaha MG166CX-USB 16-Input 6-Bus USB Rack Mountable Mixer, Six Stagg 20-Foot XLR-XLR Cables and Polishing Cloth. The MG124C is a compact mixer with 12 input channels: six mono and four stereo line inputs. Mono inputs have switchable 48V phantom power. Stereo inputs can accept either RCA or 1/4" connectors. The first 4 mono input channels offer single-knob compression, a Yamaha exclusive. This feature, designed for easy use, allows inputs with very wide dynamics to be better heard. For example, with the right amount of compression, a vocal that must be whispered in quiet parts and screamed out in louder parts will be better balanced in the mix. Two aux sends are available. One fixed post fader and one switchable pre or post fader. Dual 12-segment LED meters allow visual monitoring of the main stereo outputs.
