About Art Pro Audio MX821S

If you're seeking a professional-grade audio mixing solution, the ART MX821S 8-Channel Mic/Line Mixer with Stereo Outputs stands out as a reliable and high-quality choice for audio professionals and enthusiasts alike. This durable, rack-mountable mixer is designed to seamlessly blend eight independent input channels into a refined stereo line-level output, ideal for a multitude of environments including live sound, recording studios, and broadcast facilities.

Each of the eight channels on the MX821S accommodates both a balanced XLR microphone input and an unbalanced 1/4-inch TS line-level signal, offering versatile connectivity options. Users can fine-tune their audio with precision, thanks to independent level and pan controls for each channel. The inclusion of +48 Volt phantom power, which can be independently activated for each microphone input, ensures compatibility with a wide range of microphones.

For those who require meticulous control over their audio output, the MX821S features a master level control that adjusts the signal output to the low-impedance balanced 1/4-inch TRS jacks. Moreover, the prefade output - remaining unaffected by the master level control - and Aux Bus input RCA jacks facilitate the patching of multiple units, making this mixer a scalable solution for setups that demand more channels.

The ART MX821S is not only built for versatility but also for ease of integration into any professional audio setup. Its single high 19-inch rack mount format allows for straightforward installation, while the built-in power supply ensures reliable long-term operation. Whether it's for stage performances, studio recording sessions, or permanent installations in conference rooms, corporate boardrooms, churches, restaurants, small clubs, or health clubs, the MX821S delivers consistent, high-quality audio management.

In summary, the ART MX821S is a robust and professional 8-channel mic/line mixer with the flexibility and control needed to handle complex audio scenarios, making it an essential component in any serious audio equipment arsenal.
