The MONACOR PA-900 is a high-performance, fanless PA mixing amplifier, delivering 120 W of power with exceptional reliability and silent operation. This versatile unit is the ideal core for any commercial audio installation, from offices and retail spaces to houses of worship.
120 W Power Output: Provides robust output for low-impedance (4 Ω) systems, as well as high-voltage systems (70 V and 100 V line speakers).
Silent Operation: Engineered with a fanless cooling concept for completely silent performance, making it perfect for sound-sensitive environments.
Flexible Inputs: Features 4 balanced mic/line inputs (XLR) and 1 stereo AUX input (RCA L/R), giving you extensive connectivity options for various audio sources.
Priority and Control: Mic 1 includes a dedicated priority circuit with automatic talkover, ensuring announcements override background music. Each microphone input offers individually switchable 20 V phantom power for condenser microphones.
Advanced Signal Management: Includes an insert facility for integrating external signal processors (like equalizers or feedback controllers) and a line output for feeding the signal to another amplifier or device.
Dual Power Supply: Operates on standard mains power (~230 V) or can be connected to a 24 V DC emergency power supply for critical systems.
Rack-Ready Design: Housed in a compact 2 RU enclosure with removable mounting brackets for easy installation in a standard 19-inch rack.
