The ART MX821S - Eight-Channel Mic/Line Mixer with Stereo Outputs is a 1RU steel chassis mixer with internal power supply. The unit provides eight selectable balanced XLR microphone inputs with optional +48V low noise phantom power or eight unbalanced 1/4" TS line inputs. Each channel has both an independent level and pan control for placing the channel within the stereo image.
For outputs the unit features left and right 1/4" TRS outputs. Additionally each line input jack can be individually converted to a direct line output by means of an internal jumper system within the device. The unit's prefade output jacks and auxiliary bus input jacks also allow multiple units to be connected together to expand the system's I/O. The unit is suitable for a wide range of applications including stage, studio, and permanent installs such as for conference rooms, corporate boardrooms, churches, restaurants, small clubs, health clubs and more.
