MX821S
8-Channel Personal Mixer Stereo
The MX821S is an eight-channel stereo rackmount mixer.
Each channel has an XLR mic input with switchable phantom power, an unbalanced 1/4” line input, and independent level and pan controls. The line input can also be converted to a direct output by adjusting the internal jumpers.
The master level knob controls the balanced 1/4” outputs. There’s also a pre-fader output and aux input with stereo RCA connections for chaining multiple units together, adding an additional stereo source, or sending a mix to a recording device that is unaffected by master level changes in the room.
Simple, streamlined, and featuring the most mic preamps of any ART rack mixer, the MX821S can serve as a standalone solution or add connectivity to an existing system.
Features
- Eight input channels with individual level and pan controls
- Pan controls place each input mono signal anywhere in the output stereo image
- Balanced microphone XLR or unbalanced 1/4-inch TS inputs on each channel Full
- +48V low noise phantom power switchable for each microphone input
- Balanced left and right 1/4-inch TRS main output jacks with master level control
- Prefade Output jacks and Aux Bus Input jacks allow units to be chained to provide extra inputs
- Each line input jack may be individually converted to a direct line output by means of
- internal jumpers Rugged 1U rack-mount steel chassis with built-in power supply
- Perfect for stage, studio and permanent installations
