LAB GRUPPEN FA2402_US1 2 x 240W Commercial Amplifier with Direct Drive Technology and Energy Star Certification (FA2402_US1)

The 2 x 240 Watt dual-channel Amplifier serves as an excellent solution for commercial and industrial settings seeking superior distributed audio quality while prioritizing energy conservation and reduced operational costs. Its capability to deliver high-quality sound across both Low-Z (4/8 Ohm) and High-Z (70/100 V) loudspeaker configurations ensures remarkable flexibility on every channel. The FA2402's user-friendly installation and operation make it accessible even to non-technical personnel. Positioned ideally for various venues such as bars, restaurants, retail spaces, hotels, corporate environments, educational institutions, or any location requiring background music or a reliable public address system, the FA2402 stands out as a versatile and reliable audio solution.

Energy Star * Certified

The FA2402's direct drive constant power technology not only ensures exceptional audio performance and reliability but also boasts remarkable energy efficiency, earning it the prestigious Energy Star certification. This groundbreaking technology facilitates the creation of powerful amplifier systems that not only lower electricity expenses but also diminish installation requirements and costs for the main supply. Leveraging existing mains infrastructure during installation is highly probable, resulting in substantial savings in both installation and ongoing operational costs, while also contributing to environmental conservation. This amalgamation of efficiency, cost savings, and environmental preservation highlights the FA2402's exceptional value proposition.

Easy to install

The FA2402 offers versatile placement options. It includes rubber feet, facilitating placement on desks, shelves, or any flat surface without the need for additional installation. Moreover, it provides optional rack mounting hardware, enabling the enclosure and protection of one or multiple units. This flexibility extends to various housing configurations - a single product can fit into a half 19" rack or a full rack enclosure. Additionally, two amplifiers can be easily mounted side-by-side within a single rack space. Furthermore, utilizing the included brackets, the unit can be wall-mounted or conveniently placed under a table or shelf, ensuring adaptable placement options to suit diverse spatial requirements.

Automatic Power On/Off

The FA2402 boasts a flexible power scheme that intuitively activates or deactivates based on the input signal, effectively reducing consumption during signal absence. Requiring minimal configuration, this energy-smart amplifier system sets up effortlessly for hands-free operation. In situations where the FA2402 is powered but doesn't receive an input signal for 20 minutes, the system seamlessly transitions into sleep mode, minimizing power usage. Once the Auto Ramp circuit detects a signal, the system promptly powers on, resuming normal operation. Additionally, the amplifier offers quick access to standby mode or activation via the front panel power button, providing convenient control options for immediate operation or standby as needed.

Tamperproof Gain Controls

FA2402’s input gain controls are placed on the rear panel for tamperproof operation. Available for adjustment – but requires a tool when making changes.

Easy to Hook Up

The FA2402 offers convenient connectivity options. It features a standard 3-pin Euroblock Input socket for linking to a balanced source like a mixer or audio processor. Additionally, the Loudspeaker Output is available through a standard 2-pin Euroblock socket, ensuring compatibility and ease of connection for various setups and configurations.

Output Configuration

Adjacent to the rear panel Euroblock output connector, intuitive configuration options for the flexible output channels are available via dip switches. These switches allow seamless selection between 100 V, 70 V, 8 Ω, or 4 Ω operation, effectively setting both the maximum voltage of the output and the gain across the device. Additionally, there's an individual control dedicated to engaging the built-in high-pass filter. This feature is essential for constant voltage systems, preventing saturation on transformer-enabled loudspeakers and contributing to preserving sound integrity. Utilizing the high-pass filter is recommended for ensuring optimal performance and sound quality in various setups.

Expandable Remote Control

The RJ45 receptacle located on the rear panel expands the possibilities for remote control, offering a wide array of options such as compatibility with the CRC-V Series of wall controllers and the sleek LAB.LEVEL tabletop controller. These controllers can easily interconnect using affordable and commonly available Ethernet cabling, providing a convenient and cost-effective means for remote control and management of the FA2402 amplifier.

System Scalability

Absolutely! The FA2402 belongs to a versatile product family offering both single and dual-zone solutions, making it ideal for expanding and adapting systems of varying sizes over time. Its individual zone volume controls and remote control capabilities make the FA2402 a perfect foundational element for constructing a dynamic and scalable system solution. This flexibility ensures seamless integration of the FA2402 and its counterparts into evolving commercial installations. Whether the need is for a smaller, single-zone setup or a more complex, multi-zone configuration, the FA2402 stands ready to adapt and grow along with the changing requirements, providing customizable control and scalability to meet diverse needs.

Real-World Energy Savings

The FA2402 2 X 240Watt Commercial Amplifier simplifies the delivery of top-quality music and announcements to business and industrial environments. Its seamless integration and user-friendly operation ensure a straightforward system setup and operation. Moreover, equipped with advanced features like Auto Ramp and revolutionary direct drive constant power technology, the Energy Star-certified FA2402 doesn't just excel in performance but also boasts impressive energy efficiency. The resulting energy savings are so substantial that the FA2402 can practically cover its own costs in an incredibly short time frame, making it an exceptionally cost-effective and efficient choice for businesses seeking quality and savings in their audio systems.
