Tips Before Using:

Switch to the right working mode (TX or RX) before powering on. As a transmitter (TX), it should pair to receiving devices, such as Bluetooth headphones or speaker. As a receiver (RX), it should pair to transmitting audio sources, such as your phone or tablet. You can’t pair two transmitting devices or two receiving devices together;
If you want to use it as a transmitter and connect to your TV, please refer to the user manual of your TV and find the right AUDIO OUT port (3.5mm or white/red RCA), instead of any VIDEO or AUDIO IN ports. If your TV only offers the digital optical audio out port, please order another model instead: TROND BT-DUO S;
Your wireless headphones or speakers also need to support the codec of aptX Low Latency in order to reduce the audio latency to 40ms. Otherwise, the codec will be downgraded to aptX or even SBC;
If TROND BT-DUO S gets stuck and all the buttons stop working properly, please press & hold the MFB, and plug in the external USB charger to shut down BT-DUO S. Please note that this operation won’t delete the previous pairing record;
If you’d like to delete all the pairing record, please refer to the section of “Frequent Asked Questions” at the end of the user manual for how to reset TROND BT-DUO S.

Important Remarks:

TROND BT-DUO S doesn’t have the built-in microphone and hence doesn’t support phone calls;
You can use TROND BT-DUO S either as a transmitter OR as a receiver. This adapter won’t be able to transmit and receive audio at the same time;
The latency of 40ms is still unacceptable for live sound monitoring. Therefore, those who plan to use it with electric paino or guitar, beware! Bluetooth technology, even with aptX Low Latency, may not suit your needs;
We wouldn’t suggest you using TROND BT-DUO S in the transmitter mode to pair with your car Bluetooth system, as some cars require entering a certain pin code for pairing and TROND BT-DUO S doesn’t have the keypad for you to enter the pin code;
If you have any difficulty in pairing with your Bluetooth headphones or speakers, please always feel free to reach us for the technical assistance.

Mode I: Bluetooth Transmitter (TX)

TX Application:

Switch to “TX” mode, connect it to the audio OUT port of your non-Bluetooth audio source, such as TV, tablet, CD-player, Nintendo Switch/3DS, and then pair it with your wireless headphones. Start enjoying music, watching video or playing games without disturbing someone next to you.

Lip-Sync with AptX Low Latency

With aptX Low Latency, it can effectively minimize the audio delay, which allows you to watch late night TV shows in a synchronized way. Please order TROND TD-BH01 Over-Ear Bluetooth V4.2 Headphones for the best low latency performance.

Dual Stream

TROND BT-DUO S can pair up to two Bluetooth audio devices simultaneously, and streams audio to both of them. However, in this case, the codec would be downgraded from aptX LL to SBC. Please order TROND BT-DUO II transmitter if you’d prefer aptX LL for both two devices.

Mode II: Bluetooth Receiver (RX)

RX Application:
Switch to “RX” mode, connect it to the audio IN port of your wired audio device, such as wired earbuds, speaker or car stereo via 3.5mm cable, and pair it with Bluetooth-enabled audio sources such as your smartphone, tablet or laptop. This way, you could enjoy high-quality music wirelessly without spending more to order Bluetooth headphones or speaker.

AptX Low Latency for RX Mode
Unlike most other 2-in-1 transceivers which don’t support aptX LL or aptX in the receiver mode, TROND BT-DUO S is ideal for turning your wired headphones, speakers or car stereo into Bluetooth-enabled headphones or speakers with the feature of aptX Low Latency.

You can pair two smartphones (or tablets) to this receiver simultaneously. However, it can only receive the audio from one phone at a time. You need to pause the music on one phone first in order to play music from the other phone.
