Network Power Amplifier

Zycoo Network Power Amplifiers — SD Series

A network power amplifier takes the place of a traditional head-end  amplifier. The Zycoo SD series receives audio directly from the IP network  and drives passive speakers on the existing wiring — no rack amplifier,  no separate audio distribution, no analog source equipment.

Amplifier or gateway?

Both approaches bring analog speakers onto an IP system, but they solve  different problems:

 
• Use a network amplifier when the existing amplifier        is failing, undersized, or absent — you're keeping the speakers and        the wiring, replacing the electronics
 
• Use a paging        gateway when the existing amplifier is sound and you        only need to feed it network audio

Typical applications

 
• Buildings where the speaker wiring is in good condition but the        amplifier rack has reached end of life
 
• Distributed installations where placing an amplifier per zone is        simpler than running long speaker cable back to a central rack
 
• Sites with no existing PA electronics — new passive speakers with        network amplification and no head-end at all

Specification notes

Match the amplifier output rating to the total connected speaker load,  with headroom for future additions. Confirm whether your installation is  70V constant-voltage or low-impedance before ordering, and account for  mains power at each amplifier location — unlike PoE endpoints, these  require local power.
