MONACOR PA-40120: 4-Zone Mono Mixing Amplifier
The MONACOR PA-40120 is a professional 4-zone mono mixing amplifier designed for setting up flexible, multi-zone Public Address (PA) and Voice Alarm systems. With four independently active 120W outputs, this powerhouse allows you to deliver different audio programs to distinct areas simultaneously without interruptions.
Key Features:
Powerful Multi-Zone Control: Features four active outputs, each delivering a robust 120 W of power (at 100 V or 4 Ω), perfect for large-scale installations.
Flexible Routing: A switch matrix allows any of the 5 input channels (3 x Mic/Line and 2 x Line) to be assigned to any of the 4 zones, ensuring each area receives the correct audio program.
Voice Alarm Ready: Equipped for emergency operation with 24 V emergency power capability and connections for external momentary push-buttons to activate chime and siren functions. It can be used to set up alarm systems, such as in schools, when combined with an integrated voice memory solution.
Expandable System: Easily upgrade to a complete 4-channel system with the optional PA-4000RC zone-paging microphone (supporting up to 32 units).
Professional Inputs & Controls: Includes 3 versatile combo Mic/Line inputs with 15 V phantom power for electret microphones, along with dedicated Bass, Treble, and Master controls for precise audio shaping.
Reliable Operation: Built with a regulated fan and a compact 2 RU design for easy rack installation.
