Description

Overview

The Macsys PAS-NA260 is a 260W IP integrated Class D amplifier in a compact 1U rack design, delivering high-quality audio with low distortion and excellent SNR. It supports balanced/unbalanced line inputs, MIC, AUX1/2, AUX output, dual RCA line output, and 100V speaker outputs for flexible setups.

SIP compatibility enables integration with VoIP systems and Macsys software, supporting live paging, cross-network access, and offline broadcasting via built-in storage with FTP-uploaded files. Relay I/O allows fire alarm and third-party integration with auto-alarm playback.

The amplifier ensures reliable operation with protections against overvoltage, overload, overheating, short-circuit, lightning, and surges, plus intelligent cooling with forced air. Configurable via web interface or Config Tool, it offers wide AC 100–240V operation, hidden volume control, and front-panel status indicators—making it ideal for professional PA and emergency broadcast applications.
