Optical Receiver (RX) Mode Setup

Use this mode to receive audio from your phone or laptop via Bluetooth and play it through your home stereo or soundbar.

1. Connect your soundbar or AV receiver to the RTX PRO's Optical Output (To Speaker) port using an optical cable.
2. Ensure the RTX PRO is set to RX (Receiver) mode.
3. Power on the RTX PRO using the provided USB-C power cable and adapter.
4. On your phone or laptop, search for Bluetooth devices and select "Miccus RTX PRO" to pair.

Note: In RX mode, the HDMI port is not active. Connection out must be made via Optical or 3.5mm. The RTX Pro does not convert analog audio to digital audio or vice versa.

Operating Instructions

Pairing Bluetooth Devices

To pair a new Bluetooth device with the RTX PRO:

1. Ensure the RTX PRO is powered on and in the desired mode (TX or RX).
2. Put your Bluetooth headphones or speaker (in TX mode) or your phone/laptop (in RX mode) into pairing mode. Refer to your device's manual for specific instructions.
3. The RTX PRO will automatically search for and connect to the nearest available Bluetooth device. Indicator lights on the RTX PRO will confirm a successful connection.
4. For dual-link (connecting two headphones), after the first device is paired, put the second device into pairing mode. The RTX PRO will attempt to connect to it.

Mode Selection (TX/RX)

Use the TX/RX switch on the RTX PRO to select the desired operating mode:

• TX (Transmitter) Mode: Transmits audio from the RTX PRO's inputs to Bluetooth headphones or speakers.
• RX (Receiver) Mode: Receives audio from a Bluetooth source (e.g., phone) and outputs it through the RTX PRO's audio outputs.

Codec Selection (aptX HD / aptX Low Latency)

The RTX PRO supports both aptX HD for superior audio quality and aptX Low Latency for minimal audio delay. Use the LL/HD switch to prioritize your preferred codec:

• aptX HD: Provides 24-bit "better than CD" sound quality. Ideal for music listening.
• aptX Low Latency: Ensures audio is in sync with video, ideal for watching TV or movies.

Note: For aptX codecs to be active, both the RTX PRO and the connected Bluetooth device must support the selected codec.

  • Ensure the RTX PRO is in pairing mode (indicator light flashing).
  • Put your Bluetooth device into pairing mode.
  • Clear previous pairings on both the RTX PRO and your Bluetooth device, then try pairing again.
  • Move the devices closer together during the pairing process.
• Short Range or Audio Drops:
  • Ensure the dipole antenna is securely attached and oriented for optimal reception.
  • Minimize physical obstructions (walls, metal objects) between the RTX PRO and your Bluetooth device.
  • Temporarily disable nearby Wi-Fi routers during setup to reduce potential interference.
  • Ensure your paired device is fully charged.
• Audio Lip Sync Delay:
  • Verify that both the RTX PRO and your connected Bluetooth headphones/speaker support aptX Low Latency.
  • Select aptX-LL using the Codec Select switch on the RTX PRO.
