Operating Range
How Does 3-Level Stability Works?
Level 1 - Low Latency Mode (~7.33ms)
- Prioritizes speed and response time.
- Ideal for practice rooms, home, and small stages.
Level 2 - Standard Mode (~10.85ms)
- Balances latency and stability for most real-world application.
- Works great for club stages, studios, and bigger gig setups with some wireless activity.
Level 3 - Stable Mode (~14.33ms)
- Prioritizes signal reliability and interference-resistance over raw latency.
- Perfect for large venues, outdoor shows, or crowded wireless environments (like festivals or conventions).
