Each channel has an AUX 5/6 shift button, expanding the number of outputs available. But that´s not all. The mixer features a dual-position input/output (I/O) pod that lets you use it as a desktop mixer or convert for rack mounting. The I/O pod rotates out of the way to save space in your rack. The built-in 32/40 bit digital effect processor has 16 awesome programs, main parameter control, foot switch control and tap delay. And if you get any "sub" Sonic noise in your mics just hit the low cut filter to get rid of the P-pops, stage rumble and wind noise. Top it off with a subwoofer output, four true subgroups and global phantom power, and you´ve got a perfect medium-sized rack-mountable mixer for live events or studio mixing.
