Avantree Bluetooth transmitter and receiver audio volume loss should be less than 5%, comparing with wired connection.
If you find the output volume via Avantree transmitter is very low, here is the check list:
- Is Priva connected to the right analog output connector? More details see - http://support.avantree.com/hc/en-us/articles/204014885-How-to-connect-Priva-BTTC-400-to-TV-
- Is the output from the connector very low anyway? This can be tested by using the wired connection to test and compare.
- If none of the above reasons, pls contact firstname.lastname@example.org
