Our BHX headset is now upgraded to BT Version 4.2 and Our TosBlue units are upgraded to BT Versions 4.0 for excellent sound performance. The sound improvement is most noticable in the bass area.
Both TosBlue-x and TosBlue-Y togeter with our BHX headset have the best aptx technology embedded. This means prictically no sound delay. This is important when watching TV. The illustration below shows a user situation. We now cxall the combination of a BHX headset and a TosBlue unit for a tvSoudCast set.
Note that in order to have no sound delay, both sender (the TosBlue unit) and the receiver must have aptX installed.
The challange arises when you use a Bluetooth headset – or Bluetooth speaker – with no aptx technology. This means there will be a delay of several hundred milliseconds. This means that the sound from the internal TV speakers will arrive at your ears earlier than the sound via your headset or bluetooth speakers. If this difference is more than 50 milliseconsds – you will start noticing it.
Therefore, if you are using a Bluetooth headset or a Bluetooth speaker without aptx technology, you will most likely notice sound delay. This means some type of syncronisation improvement may be required.
Here is what you can do about it:
If you have a BT receiver without aptx technology – and the sound delay is more than 50 milliseconds, this delay start to be noticable.
Here are the recommendations:
1. Ajust timing of TV sound output port – the Toslink (SPIDIF) .
Most modern TV’s with digital optical (Toslink – SPDIF) output port are also furnished with a feature whereby the timing of the audio output may be adjusted forth and back. The procedure varies from one TV to another. However, here is a general guideline:
On the remote controller, you click on the “MENU” button. Then click “SOUND”. Then go to “SPDIF- DELAY”. You may now find a sliding bar. Draw the handle forth and back until the sound from the internal TV speakers and the sound from Your Bluetooth receiver – is synchronized.
You may also consult your TV User Guide or talk to your local TV shop for details.
2. Use only one sound path
Turn the internal TVspeakers completely OFF and only use the Bluetooth headset or the Bluetooth speaker. The sound will now be crear and crisp. However, you may notice that the TV picture and the sound is somewhat out of sync.
3. Invest is a Bluetooth receiver with best aptx technology
