Power Amplifier

Model ZP-32120D/ZP-32240D/ZP-32350D/ZP-32500D

Product Overview
ZP-32(ZP-32120D/ZP-32240D/ZP-32350D/ZP-32500D) series is a two-channel Class-D power amplifier built in compact 1U rack-mount chassis. It supports dual output modes of 100V constant voltage and 8-ohm low impedance, with continuous RMS power ranging from 2×150W to 2×500W for flexible project matching.
Adopting efficient Class-D circuit design, it features low heat generation, high energy efficiency and stable long-running performance. Standard 1U rack size enables easy integration into audio equipment cabinets. Suitable for conference rooms, classrooms, multi-function halls and public address systems to drive wall speakers and other audio terminals.
