TIPS:
1) Working time will be different depend on different working environment and CODEC.
2) CODEC code depends on the paired devices and follow the turns as the priority support.
TIPS:
● The latency of 40ms is still unacceptable for live performance. Therefore, musicians
beware! Bluetooth technology even with apt-X Low Latency may not suit your needs.
● apt-X Low Latency can only be enable in Both Single Link and Dual Link. Please make
sure Both paired Bluetooth Headphones/Speakers also support aptX Low latency.
TIPS:
1) If BTI-018 can’t connect two devices, please turn off BTI-018 and then re-start..

devices in the market, and for some devices, it may have intermittent music, silence, or
poor connection.
3) Audio code choice:
●Priority support aptX™ low latency for one connection (Connected device must support
aptX™ low latency), support aptX™ low latency for two connections if two devices priority
support aptX™ low latency;
● Support aptX™ for two connections if two devices priority support aptX™;
● It will turn to SBC if two devices CODEC is not the same like one support aptX™ low
latecy and another one support aptX™.
4) During Dual Link connections, When connecting the second device but not disconnect
the first device, when the second device is connected successfully will with temporarily
bad working, please wait for 5 to 20 seconds for normal working.

To take advantage of the better performance of the apt-X Low latency Codec,
the other side device must support the same codec. If the other side device
only the normal apt-X codec, or the SBC codec, these codec will be used
instead.

The BTI-018 supports the aptX Low Latency codec(aptX-LL) streaming audio with
a ≤40ms audio delay that is undetectable by human ear, making it ideal for watching
TV/movies/video without audio lag. However, to achieve this your Bluetooth receiver
(headphones/speaker) must also support aptX Low Latency otherwise they will
connect using the standard SBC codec which has about 220ms of audio latency.
If you have any issue in the usage, please read the user manual carefully
firstly. We believe you can find the right.

Please re-charge it and make sure the adapter has enough battery power. Plug the

sound system or volume is very little.
Please check the below comment as the working mode.
Q9: Why can’t I pair the BTI-018 to my headphones / speaker?
This can be caused by either the BTI-018 or your headphones/speaker unintentionally
pairing with another nearby Bluetooth device. To avoid this, Please turn off all other
Bluetooth devices in the area.
Q10: Why am I hearing noise from my headphone / speaker?
1. FOR AV RECEIVERS - ONLY use the BIG 6.35MM PHONE OUT on the front
panel of your AV Receiver with the 6.35mm to 3.5mm adapter.
2. DO NOT use the PREAMP output RCA (L/R) ports on the back panel of your AV
Receiver - these can damage your product, FOR TV.
3. Try powering up the BTI-018 using a different USB charger (5V/0.5-2A).
4. Try a different audio cable to connect the BTI-018 to your audio source. Clear the
pairing history of Both the BTI-018 and your headphones.
Q11: Why should I use aptX Low Latency supported Bluetooth adapters?
