Description

Overview

Macsys PAS-NMA130-4Z is a multi-zone IP mixer amplifier designed for versatile applications such as supermarkets, office buildings, and schools. It combines a pre-amplifier with independent bass and treble controls, allowing per-channel sound shaping.

Equipped with a digital Class-D 130W amplifier, it supports both 100V and 8–16Ω loudspeakers, offering four independently controlled output zones for flexible area coverage. Server-independent timed broadcasting is enabled through an internal clock chip, with programs stored on a local SD card. A built-in microphone and speaker provide reliable two-way intercom functionality.

The amplifier features a 2U rack-mount design with a 4.3-inch TFT color LCD, control knob, and IR remote compatibility. It includes comprehensive protection mechanisms, while an automatic fan cooling system activates above 55℃ to ensure reliable long-term operation.

For connectivity, the PAS-NMA130-4Z supports 10/100 RJ45 networking with HTTP, TCP/IP, UDP, ARP, ICMP, and IGMP protocols, managed via a web interface or Config tool for simplified deployment. Additionally, relay I/O integration enables seamless connection with third-party fire alarm systems.
