your audio source is connected to the Optical input.
3. Confi rm that audio is playing on the connected device and that volu
me is suffi ciently high. Make sure that volume is suffi ciently high on
your Bluetooth headphone/speaker.
The volume output level is low.
In TX mode: Adjust the volume both on your Bluetooth receiver and on
the connected device as both may control the volume.
In RX mode: Verify the volume levels on your smartphone / computer
OS and player app. Also check the volume levels on your powered
speakers or stereo system.
The sound quality is poor and / or the audio is cutting out.
1. Maximize the volume on your audio source and adjust volume via the
connected Bluetooth device.
2. Make sure you are within range of your Bluetooth-enabled device.
3. Bluetooth devices are susceptible to interference from other Bluetooth
devices, cordless phones, routers, microwave ovens, and wireless
devices operating on the 2.4GHz band. Eliminate as many potential
source of interference as possible while using your Bluetooth head-
phone / speaker.
There is a delay (latency) in audio
1. Bluetooth is a digital wireless signal and there are some factors that
can cause to higher latency.
2. The aptX and aptX Low Latency and AAC audio codecs supported by
transceiver are notable for having lower (delay not or hardly noticeab-
le), respectively, compared to regular Bluetooth audio.
3. Using transceiver with a headphone that supports aptX, aptX Low
Latency will minimize audio lag.
4. Some modern TV's and receivers also have an audio delay option.
Make sure that audio delay is set to 0 to minimize lag.
The sound is missing, has dropouts or is only played on one
Bluetooth receiver after two devices have been connected in
transmit mode (TX).
1. Multipoint streaming with two Bluetooth receivers only works with two
identical receivers and for receivers that are explicitly equipped with a
multiconnect or multipoint function.
2. On the transceiver, switch the mode from OPT to AUX or vice versa
and back again.
The second Bluetooth receiver cannot be connected.
1. Make sure that the transceiver and the receiver to be connected are
within range.
2. Repeat the connection process on the transceiver and make sure that
the Bluetooth receiver is in pairing mode.
The previously connected Bluetooth device is not reconnecting
Bluetooth devices that automatically switch to pairing mode after
power-on cannot be reconnected automatically. Connect them manually
or replace the device.
