To connect either a 3,5''Klinke- or a RCA input is required. Conveniently, it is possible use the supplied cable in any case,
because it has a respective TRS and RCA end. The adapter itself has two connection options.
The necessary power supply to the power supply is so narrow built so that it covers not usually adjacent seats in the connector.
The pairing process could not be simpler. If the only key of the adapter is pressed, the status LED begins to flicker green.
The unit can now be found from any other Bluetooth device. Android Smartphone, Windows PC and Macbook had no problems with the pairing.
The compound is stable, even if multiple devices are connected, may at any time be changed easily without any additional settings.
Once connected, the LED lights solid green. In the inactive mode, it lights unnecessarily red.
An on / off switch does not exist, the power consumption is expected but keep very limited.
For sound: When playing MP3 files difference is audible even at a high-quality plant NO.
Only the level is slightly lower than via cable, so the volume control should be turned a little further.
And who wants to hear String concerts of high-resolution recordings at high-end speakers, certainly will not do that via Bluetooth.
The price of under thirty euros is absolutely fine for this highly functional Bluetooth adapter.
