The Monacor PA-1850D is a powerful and energy-efficient 8-channel Class D Public Address (PA) amplifier, engineered for reliable, multi-zone sound reinforcement in professional environments like restaurants, hotels, schools, and event venues.
Utilizing highly-efficient Class D technology, the PA-1850D delivers 8 x 50 W of output power, significantly reducing energy consumption and operational costs while minimizing heat generation. Its robust design and versatile features make it an ideal choice for complex installation scenarios.
Â
Â
8-Channel Output: Provides 8 separate channels with an output rating of 8 x 50 W (RMS) at both 4 ohms and 70/100 V line operation, making it suitable for a wide range of speaker systems and multi-zone configurations.
High Efficiency Class D Design:
Reduced Energy Costs: Lower power consumption translates to substantial savings.
Low Heat Dispersion: The minimized heat generation leads to reduced cooling requirements.
Silent Operation: Features a fanless cooling concept for completely silent operation, perfect for noise-sensitive areas.
Emergency Power Ready: Requires a lower rechargeable battery capacity for 24 V DC emergency power operation compared to standard 100 V analogue amplifiers.
Precise Control & Monitoring:
Individual Level Control: Each of the 8 channels has its own level control for precise volume adjustment in different zones.
Channel Mute Function: Allows for individually muting each channel.
LED Indication: Features CLIP and PROTECT LEDs for each channel pair, providing clear visual feedback on the operating status and safety.
Versatile Power and Safety:
Operates via standard mains power (230 V / 50 Hz) or alternative 24 V DC emergency power supply.
Protected against short circuit for enhanced operational safety and durability.
Flexible Connectivity:
Inputs: Features 8 x balanced XLR inputs and 8 x unbalanced RCA inputs.
Outputs: Speaker connections utilize screw terminals for secure wiring.
Installation Friendly: A compact 2-rack unit (2 RU) design for easy integration into standard 19" rack cabinets.
