- Connect the D600's AUX or RCA input to the audio output of your TV, PC, or other wired audio source using the provided 3.5mm AUX or RCA cable.
- Alternatively, for TV/PC audio transmission, you can plug the USB-C cable directly into your TV/PC's USB port for both power and audio output.
5. Bluetooth Pairing
In RX (Receiver) Mode:
- Ensure the D600 is in RX mode.
- The D600 will automatically enter pairing mode, indicated by a flashing Bluetooth pairing light.
- On your source device (smartphone, tablet, laptop), enable Bluetooth and search for available devices.
- Select "D600" from the list to connect. Once connected, the Bluetooth pairing light will become solid.
In TX (Transmitter) Mode:
- Ensure the D600 is in TX mode.
- Place your Bluetooth receiving device (headphones, speaker) into pairing mode.
- The D600 will automatically search for and connect to nearby Bluetooth devices. The A or B indicator will light up when a device is connected.
- If multiple devices are found, you may need to briefly press the Bluetooth pairing button on the D600 to cycle through and select the desired device.
Operating Instructions
Basic Controls
- Play/Pause: Press the Play/Pause button to play or pause audio.
- Volume Up/Next Track: Short press for Volume Up. Long press for Next Track.
- Volume Down/Previous Track: Short press for Volume Down. Long press for Previous Track.
- Bluetooth Pairing Button: Short press to re-enter pairing mode or switch between paired devices (in TX mode).
Codec Indicators
The D600 features LED indicators for the active audio codec:
- SBC: Standard Bluetooth codec.

The D600 supports connecting to two Bluetooth devices simultaneously, both in RX and TX modes:
- In TX Mode: Connect two Bluetooth headphones or speakers to the D600. Audio will be transmitted to both devices. (Note: aptX-LL only supports transmission to one device at a time).
- In RX Mode: Connect two mobile phones or tablets to the D600. You can switch between the audio sources from the two connected devices.
To establish a dual connection:
- Connect the first device as per the pairing instructions. The 'A' indicator will light up.
- Put the second device into pairing mode.
- Briefly press the Bluetooth pairing button on the D600 to search for and connect to the second device. The 'B' indicator will light up once connected.
Maintenance
- Keep the device dry. Moisture can damage the internal circuits.
- Do not expose the device to extreme temperatures.
- Clean the device with a soft, dry cloth. Do not use harsh chemicals or detergents.
- Avoid dropping or subjecting the device to strong impacts.
- Store the device in a cool, dry place when not in use.
Troubleshooting
- No Power: Ensure the Type-C cable is securely connected to both the D600 and a working 5V USB power source.
- Cannot Pair: Make sure the D600 is in the correct RX/TX mode. Ensure your source/receiving device is in pairing mode and within range (up to 30m). Try restarting both the D600 and the other Bluetooth device.
- No Audio: Check all audio cable connections (AUX/RCA). Ensure the correct input/output is selected on your audio system. Verify that the volume is turned up on both the D600 and the connected audio devices.
- Poor Audio Quality/Intermittent Connection: Ensure there are no obstructions between the D600 and the connected Bluetooth device. Move closer to the D600. Check for potential interference from other wireless devices. The D600 will automatically try to use the best available codec; ensure your connected device also supports high-quality codecs like aptX HD for optimal performance.
- Dual Connection Issues: Ensure both devices are in pairing mode when attempting to connect the second device. Some older Bluetooth devices may not fully support dual connections.
User Tips
- For the best audio quality, ensure your source device and receiving device (headphones/speakers) also support aptX HD or aptX Low Latency codecs. The D600 will automatically negotiate the highest common codec.
- When using in TX mode with a TV, if your TV has a USB port, you can often use it to power the D600 directly, simplifying cable management.
- If experiencing latency issues, especially with video, ensure both the D600 and your receiving device support aptX Low Latency (aptX LL) and that the LL codec indicator is lit.
- Keep the antenna upright and unobstructed for maximum transmission range and stability.
