Lab Gruppen CA2402 - 240W 2-Channel at 4-Ohm 70V/100V Commercial Amplifier with Euroblock Outputs and Energy Star Certification in Black Finish

The Lab Gruppen CA2402 is a 2-channel, 240W commercial amplifier designed to meet the audio needs of commercial and industrial environments, where high-quality distributed audio and energy efficiency are key priorities. Ideal for applications in venues such as bars, restaurants, retail spaces, hotels, corporate environments, and educational facilities, the CA2402 ensures exceptional sound reproduction while minimizing operational costs. This amplifier delivers superior performance with both Low-Z (4/8 Ohm) and High-Z (70V/100V) loudspeaker configurations, providing the flexibility needed for various installation types and speaker setups.

At the core of the CA2402 is its direct drive constant power technology, which offers high reliability and efficiency while consuming less power compared to competing models. The amplifier's Energy Star certification underscores its commitment to energy conservation, making it a cost-effective choice for businesses looking to reduce both electrical and installation expenses. The technology allows the CA2402 to achieve high output while maintaining lower power consumption, and in many cases, it can be installed using existing mains infrastructure, further cutting down on installation costs and environmental impact.

The CA2402 is designed for ease of use, featuring intuitive front-panel controls, including a power standby button, master volume knob, and tone controls for bass and treble adjustments. These simple controls make it accessible even to non-technical personnel, ensuring smooth operation in diverse environments. The rear panel provides additional flexibility with input options: a balanced 3-pin Euroblock connector for audio processors or mixers, as well as RCA inputs for unbalanced sources such as phones or media players. The rear panel also includes output connections via a 4-pin Euroblock connector, along with dipswitches to select between 4Ω, 8Ω, 70V, or 100V operation. The high-pass filter can be engaged to protect transformer-enabled loudspeakers and preserve sound quality.

For enhanced power management, the CA2402 incorporates Auto Ramp circuitry, which ensures a smooth power-up and power-down process, optimizing energy savings. If no input signal is detected for 20 minutes, the amplifier automatically enters sleep mode to conserve power. Upon receiving a signal, the amplifier instantly resumes normal operation. The system can also be manually switched into standby mode using the front panel power button. With its fanless convection-cooled design, the CA2402 operates quietly, ensuring minimal noise disturbance in noise-sensitive environments and reducing the need for ongoing maintenance.

Designed for flexibility in installation, the CA2402 comes with rubber feet for easy placement on desks, shelves, or tables, but it also includes optional rack mounting hardware. This allows the amplifier to be housed in a half-19" or full-rack enclosure or mounted side by side with other units in a single rack space. Additionally, the included brackets make it possible to mount the amplifier to a wall or under a table, providing versatile installation options. The amplifier is equipped with several protection mechanisms, including thermal protection, overcurrent protection, DC protection, and high-frequency protection, ensuring reliable operation even in challenging environments.
