Features:
The ART MX821S is a versatile rack mixer with eight independent input channels and a stereo line output. Each input channel accepts both balanced mic (XLR) and unbalanced line (6.3mm jack) signals with independent level and pan control.
48-volt phantom power can be switched per mic input. A master level control determines the signal output to the low impedance, balanced 6.3mm phone jacks. Prefader output (not affected by master level control) and an aux bus input (RCA) allow patching of multiple units.
If you need a basic no frills line mixer this does the job. I use it to blend a number of send effects before they hit my main boards returns. Would be fine for a small project studio or live applications.
