Mute the Boat stereo and Hear VHF/UHF Radio Audio through Stereo Boat Speakers
VHF-U4 is a VHF/UHF radio voice activated stereo mute and speaker switching system that allows seamless interaction between the VHF radio voice message and the boat stereo speakers.
When activated the boat stereo mutes and the two front speakers switch to VHF radio voice while the rear speakers go mute. Three seconds after the last voice message is received the stereo automatically returns back to normal play.
Designed and manufactured in the USA.
