Product Q&A


Is it possible to connect this appliance to a Samsung 6 Series smart TV without cutting off the TV's speakers? I have a sound bar with sub-woofer fitted, which might using a microphone difficult.

Sarabec's Reply:

It depends on the TV whether the speakers cut off, but if you used an optical splitter the signal would be shared between the soundbar and the sonumaxx. you would also need to change the TV's


How does the 230/450 pick up sound from TV? does it need a cable connection or is it completely wireless?

Sarabec's Reply:

There are a couple of options, the most popular method is a direct connection to the TV using Opticalor phono connectors that are supplied, the second method is a microphone that plugs into the back of the transmitter which is then stuck onto the speaker
