STAND ALONE SPEAKER CONNECTION:
Connect your audio source to the Audio Input jack on the back
of the Speaker as shown below. This input will override the
transmitter Base audio signals.
Note: Make sure the volume level is set high on your audio source
device. The volume on the SEREONIC TV-SoundBox and your audio
source device both need to be set to highest level for the loudest
volume. The volume control on your audio source device and the
SEREONIC TV-SoundBox works independently of each other.
