The Monacor PA-4240 is a high-performance, robust 4-channel PA power amplifier engineered for demanding public address (PA) and background music (BGM) systems in large commercial environments like shopping centers, airports, sports grounds, and educational institutions. Delivering a formidable 960 W of total power, this amplifier ensures clear, consistent, and reliable audio coverage across extensive areas.
High Power Output: Features 4 separate channels, each providing 240 W of power (at 4 ohms or 100 V line) for significant audio distribution capabilities.
Versatile Output Options: Supports both low-impedance (4 ohms) and high-voltage 100 V line speaker systems, as well as 70 V and 50 V lines, offering maximum flexibility for diverse speaker configurations.
Parallel Channel Operation: Includes routing switches to allow two pairs of channels to operate in parallel, simplifying wiring and increasing configuration options.
Dual Power Supply: Designed for continuous operation with support for both mains power (230 V/ 50 Hz) and a 24 V DC emergency power input, ensuring uninterrupted performance during a power outage for critical safety announcements.
Professional Rackmount: Housed in a durable 19-inch, 3U steel chassis, making it ideal for standard rack-mounted installations in professional audio setups.
Comprehensive Monitoring: The front panel is equipped with LED indicators for clip, protection, over-temperature, and output level, enabling quick system diagnostics and operational oversight.
Optimized Cooling: A temperature-controlled fan ensures efficient cooling, maintaining optimal performance even during prolonged, continuous operation.
External Control: Features a connection for an external on/off switch, allowing for integration with central control or fire alarm systems.
The Monacor PA-4240 provides high-quality, low-distortion amplification (< 1% THD) and is the perfect, powerful core for any large-scale professional audio installation.
