Is Your Soundbar Connected Through HDMI ARC?

The HT5009 Plus bypass connection uses Optical or AUX. If your soundbar needs to stay connected to the TV through HDMI ARC, use one of these options instead.

Option 1

Use the HAX06 HDMI ARC Audio Extractor

The HAX06 lets your soundbar remain connected through HDMI ARC while providing a separate audio output for the HT5009 Plus transmitter.

Use a Crescendo TV Headphone System
