Spark LINK XLR is Positive Grid’s compact, plug-and-play wireless XLR system. It allows vocalists, instrumentalists, speakers, and live performers to connect microphones wirelessly with ultra-low latency and excellent sound quality—all in a lightweight and portable design.

Spark LINK XLR is ideal for:

• Vocalists, instrumentalists, and live performers who want wireless freedom without complexity.
  
• Musicians seeking an affordable, reliable wireless solution.
  
• Mid-level musicians who need stable wireless performance for gigs, rehearsals, or content creation.
  
• Mobile performers needing lightweight gear for travel and on-the-go performances.
  
• Speaking engagements such as panels, town halls, poetry slams, corporate presentations, public speaking events, and more—where clear wireless audio and simple setup are critical.

Spark LINK XLR is compatible with:

• Dynamic microphones for live performances, public speaking, podcasts, streaming, and studio use.
  
• Instruments miked via dynamic mics (acoustic guitar, strings, wind instruments, percussion, drums).
  
• Gear with mic-level XLR outputs such as DI boxes or guitar processors that can be set to mic-level output. 
• Spark LINK XLR supports the use of up to four units operating simultaneously in the same environment, letting you set up multiple wireless channels for vocals, instruments, or other gear. If you already own the original Spark LINK for instruments, you can also use up to four Spark LINK units in parallel, enabling a fully wireless stage setup across microphones and instruments.
  

Note: Spark LINK XLR is intended for mic-level signals. It may not be suitable for line-level connections unless your device allows switching output levels to mic.
