Lab Gruppen CPA2401 - 240W 1-Channel at 4-Ohm Commercial Mixer Amplifier with 5 Inputs and Bluetooth/USB Media Player in Black Finish

The Lab Gruppen CPA2401 is a powerful and versatile 240W 1-channel commercial mixer amplifier designed for high-performance audio distribution in commercial and industrial environments. Ideal for venues such as bars, restaurants, retail destinations, hotels, corporate offices, and educational institutions, this amplifier delivers exceptional sound quality while promoting energy conservation and reducing operational costs. The CPA2401 offers flexible input and output configurations, making it an excellent solution for both background music and public address systems.

Capable of supporting both Low-Z (4/8 Ohm) and High-Z (70/100 V) loudspeaker setups, the CPA2401 provides the versatility needed for various applications. Whether you're powering standard speakers or a distributed audio system, this amplifier adapts to your needs. The unit features a high-pass filter that ensures sound integrity in constant voltage systems, preventing saturation and distortion on transformer-enabled loudspeakers. Additionally, the rear panel offers selectable dipswitches for output configurations, enabling you to easily adjust the amplifier's output to match the system's voltage requirements, whether it be 100V, 70V, or 4/8 Ohm operation.

One of the standout features of the CPA2401 is its Bluetooth functionality, allowing seamless, high-quality audio streaming from any Bluetooth-enabled device, such as smartphones, tablets, or laptops. This eliminates the need for outdated cables and adapters, providing a simple, wireless connection for music playback. Additionally, the CPA2401 is equipped with a USB media player with an intuitive LCD interface, allowing users to play audio files directly from a USB stick. This combination of Bluetooth and USB capabilities provides modern, convenient media playback options for any commercial space.

The CPA2401 includes a total of 5 inputs: 1 x 5-pin Euroblock input for priority mic/line sources, 2 x 3-pin Euroblock inputs for mic/line audio, and 3 x RCA inputs for unbalanced stereo sources. These inputs ensure compatibility with a wide range of audio sources, from microphones and mixers to smartphones and computers. The mic inputs are equipped with 48V phantom power, allowing you to connect condenser microphones for high-quality audio capture. The front panel features individual volume controls for each input, allowing the operator to adjust each source independently. Bass and treble tone controls are also available for further fine-tuning of the audio output.

The CPA2401 is designed for ease of use, with intuitive front-panel controls that include a power standby button, master volume knob, and Bluetooth audio controls. The amplifier also offers a priority muting function, which automatically reduces the background music volume when an announcement is made, ensuring that the PA message is clearly heard. This feature is essential for environments where announcements need to be easily understood without interference from background music.

Energy efficiency is a key focus of the CPA2401's design. It features Auto Ramp circuitry, which automatically powers the amplifier on or off based on the presence of an input signal, reducing energy consumption during periods of inactivity. If no signal is received for 20 minutes, the amplifier automatically enters sleep mode. Once a signal is detected, the amplifier resumes normal operation, providing both energy savings and a hassle-free user experience. The amplifier's fanless convection-cooled design ensures quiet operation, making it ideal for noise-sensitive environments.

The CPA2401's flexible installation options add to its versatility. It comes with rubber feet for easy placement on desks, shelves, or tables. Additionally, the unit can be rack-mounted using the included hardware, allowing for integration into a 19" rack system. The amplifier's compact 1U design allows it to fit neatly in both half-rack or full-rack enclosures, and the included brackets enable wall or under-table mounting. This flexibility makes the CPA2401 suitable for a wide range of installations, from small retail spaces to large corporate offices or public venues.

Remote control capabilities are provided via the RJ-45 Ethernet connector, allowing the CPA2401 to be integrated into larger, multi-zone audio systems. Using compatible wall controllers such as the CRC-V Series or the LAB.LEVEL tabletop controller, users can easily control the volume and settings from a central location. This feature is particularly beneficial for large installations where multiple amplifiers or zones need to be managed efficiently.

Overall, the Lab Gruppen CPA2401 is an ideal solution for commercial installations requiring high-quality audio, modern media playback options, and energy-efficient operation. With Bluetooth streaming, USB media playback, and a variety of input/output options, this amplifier provides all the tools necessary to create an exceptional audio experience in any commercial setting.
