- Ensure the transmitter and receiver are within the 164ft (50m) operating range.
- Minimize physical obstructions (walls, large metal objects) between the units.
- Avoid areas with high 2.4GHz wireless interference (e.g., multiple Wi-Fi routers, other wireless devices).
- Ensure units are fully charged to maintain optimal signal strength.
8.3 Latency Issues
- The system is designed for low latency. Ensure you are operating within optimal conditions (clear line of sight, minimal interference).
- Consider switching to mono mode if stereo latency is noticeable, as mono mode offers lower latency.
