Operating Instructions
Audio Connections:
The Miccus Home RTX 2.0 supports multiple audio connection types:
- Optical (TOSLINK): For digital audio input/output, offering high-fidelity sound.
- 3.5mm (AUX): For standard analog audio input/output, compatible with most devices.

aptX Low Latency Technology:
The Miccus Home RTX 2.0 supports aptX Low Latency, which minimizes audio delay (lip-sync issues) when watching videos or playing games. For this feature to work, your paired Bluetooth headphones or speaker must also support aptX Low Latency. If your paired device does not support aptX-LL, the connection will default to a standard aptX or SBC codec, which may introduce a slight delay.

Long Range Performance:
The device is designed for extended range, offering up to 300 feet outdoors and 160 feet indoors under optimal conditions. Environmental factors such as walls, furniture, and Wi-Fi interference can affect the actual range.

Note on Wi-Fi Interference: Wi-Fi signals can sometimes interfere with Bluetooth range. If you experience range issues, try temporarily turning off Wi-Fi on nearby devices during Bluetooth setup, then re-enable Wi-Fi once the Bluetooth connection is established and streaming.
Dual Device Pairing: The Miccus Home RTX 2.0 can connect to two Bluetooth headphones or speakers simultaneously in TX mode, allowing two individuals to listen to the same audio source. In RX mode, it connects to one source device (e.g., smartphone).
