Lab Gruppen CPA1201 - 120W 1-Channel at 4-Ohm Commercial Mixer Amplifier with 5 Inputs and Bluetooth/USB Media Player in Black Finish

The Lab Gruppen CPA1201 is a 120W 1-channel commercial mixer amplifier designed to provide superior audio performance in commercial and industrial settings, such as bars, restaurants, retail destinations, hotels, corporate environments, and educational institutions. This versatile amplifier offers an ideal solution for venues requiring high-quality distributed audio for background music and public address (PA) systems. With its advanced technology and intuitive controls, the CPA1201 ensures both ease of use and outstanding sound quality while minimizing energy consumption and operational costs.

Featuring both Low-Z (4/8 Ohm) and High-Z (70V/100V) loudspeaker configurations, the CPA1201 offers excellent flexibility to meet a wide range of installation needs. It also includes a high-pass filter that helps maintain the integrity of sound, particularly in constant voltage systems, and provides clear audio without distortion or saturation. The amplifier's output is delivered via a 2-pin Euroblock connector, while an additional 3-pin Euroblock connector is available for auxiliary output, making it easy to expand the system or connect to additional amplifiers as necessary.

One of the standout features of the CPA1201 is its ability to stream high-quality audio via Bluetooth. This functionality allows for seamless, wireless music streaming from any Bluetooth-enabled device such as smartphones, tablets, or laptops. Additionally, the CPA1201 includes a USB media player, equipped with an intuitive LCD interface that allows for easy navigation and playback of audio files directly from a USB stick. This eliminates the need for outdated physical media players, offering a streamlined and modern solution for audio playback in commercial spaces.

The CPA1201 features 5 audio inputs, including 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. The mic inputs support phantom power, allowing for the use of condenser microphones, while the RCA inputs can handle stereo unbalanced signals. The front panel provides individual volume controls for each input, making it easy to adjust the levels of different audio sources independently. Bass and treble tone controls allow for further fine-tuning of the audio output to suit the acoustics of any space.

For ease of use, the CPA1201 includes simple front-panel controls, including a power standby button, master volume knob, and Bluetooth audio controls. The amplifier also features a configurable priority muting function, ensuring that background music is automatically muted when an announcement is made. This is particularly useful for public address applications, ensuring that announcements are clearly heard above the background music.

Energy efficiency is a key consideration in the design of the CPA1201. The amplifier features Auto Ramp circuitry, which automatically powers the unit on or off based on the presence of an audio signal, helping to conserve energy when not in use. After 20 minutes of inactivity, the system automatically enters sleep mode to reduce power consumption. The amplifier can be quickly awakened when a signal is detected, providing a hassle-free experience for users. Additionally, the fanless convection-cooled design ensures quiet operation, making it ideal for use in noise-sensitive environments.

The CPA1201 is built for both ease of installation and flexibility in commercial environments. It comes with rubber feet for placement on desks, shelves, or tables, but also includes optional rack-mount hardware for integration into a 19" rack. With its compact 1U design, it can easily be mounted in a half-rack or full-rack configuration, or even installed on walls or under tables using the included brackets. This flexibility ensures that the CPA1201 can be adapted to various installations and space requirements.

Additional features include remote control capabilities via the RJ-45 Ethernet connector, allowing for integration with compatible wall controllers such as the CRC-V Series or the LAB.LEVEL tabletop controller. This makes it easy to control the volume and other settings from a central location, offering convenient operation for large or multi-zone installations.

With its combination of Bluetooth streaming, USB media playback, and versatile input/output options, the CPA1201 offers a complete audio solution for any commercial installation. Whether used for background music, public address, or both, this powerful, energy-efficient amplifier provides exceptional audio performance with minimal operational costs.
