Self-Amplified

Today, the most commonly used paging technology is the use of Self-Amplified Speakers and Horns.  This represents nearly 100% of all new installations because it is inexpensive, easy to deploy and easy to troubleshoot.  It uses a simple 2-pair connection from the PBX to each speaker. One pair is for the speech and the other pair is for the power. 

Each speaker or horn has a small built-in amplifier – just for that speaker.  If the amplifier should fail for some reason, the others keep working.  Best of all, you can daisy-chain the cabling – in other words, drop and insert as needed.
