There's never been an easier way to distribute your analog audio to multiple locations. The Gefen 1:4 Audio Distribution Amplifier (EXT-AUD-144) allows you to send one analog audio signal to up to four separate locations using the same audio source. As an added bonus, the Gefen 1x4 Audio DA (EXT-AUD-144) also has the capability to extend each distributed audio signal up to 1000 feet away from your computer.

How it Works

The 1:4 Audio Distribution Amplifier (EXT-AUD-144) sender unit connects to your audio source using stereo cables supplied by Gefen. One small receiver unit per audio channel connects to each of the speakers or audio output devices (up to four at a time). One CAT-5 cable per audio channel connects the sender to the multiple receivers at the distributed locations - up to 1000 feet away.
