Troubleshooting Tips

1. If you experience noticeable audio lag, ensure that your Bluetooth headphones or speakers support aptX Low Latency.
2. If you hear static noise, avoid connecting the 3.5mm audio jack and USB charging port to the same audio source. Use a separate USB charger instead.
3. If you cannot pair the TROND BT-DUO with your Bluetooth devices, follow the "Reset BT-DUO" section in the user manual and restart the pairing process.
4. If you only get audio out of one headphone, charge the TROND BT-DUO first, then unplug it, and use it without charging at the same time.

Frequently Asked Questions

1. Can I use the TROND BT-DUO with my car's Bluetooth system for music streaming?
   The TROND BT-DUO may not be able to stream music from your iPod to your car stereo, as car Bluetooth systems may require a pin code for pairing, which the TROND BT-DUO does not support. However, you can use it as a Bluetooth receiver for cars with only an aux jack and no built-in Bluetooth functionality.
2. Can I use the TROND BT-DUO for hands-free phone calls?
   The TROND BT-DUO does not have a built-in microphone, and the in-line microphone of your wired headset will be disabled when connected to the BT-DUO as a receiver. Therefore, it does not support phone calls.
3. Can I use two TROND BT-DUO devices, one as a transmitter and the other as a receiver?
   Yes, this setup is viable and can add Bluetooth functionality to two devices, such as a TV and wired headphones. Connect the transmitter to the TV and the receiver to the wired headphones, then pair the transmitter with the receiver.

FAQ [continued]

1. What is the Trond V5.0 Bluetooth Audio Transmitter Receiver used for?
The Trond V5.0 Bluetooth Audio Transmitter Receiver can be used as both a transmitter and receiver to enable wireless audio streaming from non-Bluetooth audio sources such as TV, MP3, CD player, PC or ebook reader to Bluetooth-enabled headphones, speakers or receivers.

2. What is AptX Low Latency?
AptX Low Latency is a codec that ensures synchronized audio and video with minimal delay. Trond BT-DUO supports AptX Low Latency in both TX and RX mode, allowing you to watch movies while listening to wireless audio without any noticeable audio delay.

3. Can Trond BT-DUO transmit stereo audio wirelessly?
Yes, Trond BT-DUO can transmit stereo audio wirelessly from your non-Bluetooth audio sources to your Bluetooth-enabled headphones, speaker or receiver.

4. Can Trond BT-DUO turn old wired headphones or speakers into Bluetooth function enabled?
Yes, with the feature of AptX LL in the RX mode, Trond BT-DUO offers an economical solution by turning your old wired headphones, speakers or car/truck into Bluetooth function enabled.

5. Can Trond BT-DUO be paired to two devices simultaneously?
Yes, in the TX mode, Trond BT-DUO can be paired to two Bluetooth headphones or speakers and streams audio to both of them simultaneously. In the RX mode, it can be paired to two phones or tablets but can only receive the audio from one of the two paired devices.

6. What are some important things to consider before buying Trond BT-DUO?
It's crucial to first identify which audio OUT port your TV could support (3.5mm Aux or Digital Optical). Also, check if your device supports AptX Low Latency codec to avoid lip-sync issues. The latency of 40ms is still unacceptable for live sound monitoring, so it may not suit your needs if you plan to use it with electric piano or guitar.

7. How do I pair Trond BT-DUO with my Bluetooth devices?
To pair with one device, switch the working mode to TX, long press the MFB for 3 seconds to power it on, activate the pairing mode of your headphones, put those two close to each other and wait for pairing. To pair with two devices, follow the instructions included in the user manual.

8. Can Trond BT-DUO be used for hands-free phone calls?
No, Trond BT-DUO doesn't have a built-in microphone. If connected as a receiver, the in-line microphone of your wired headset will be disabled, and it won't be able to support any phone calls.

9. What should I do if I experience noticeable audio lag or annoying static noise?
Check if your device supports AptX Low Latency codec. Please do not connect its 3.5mm aux jack and USB charging port to the same audio source as it may easily cause "ground loop noise." Use a separate USB charger instead.

10. What is included in the package?
The package includes Trond V5.0 Bluetooth Audio Transmitter Receiver, 3.5mm aux cable (50cm), 3.5mm Aluminum Adapter, and 3.5mm female to RCA male cable adapter.
