Lab Gruppen CPA1202 - 120W 2-Channel at 4-Ohm Commercial Mixer Amplifier with 8 Inputs and Bluetooth/USB Media Player in Black Finish

The Lab Gruppen CMA1202 is a 2 x 120W commercial mixer amplifier that brings a powerful solution to commercial and industrial audio systems, delivering high-quality sound across a variety of applications, including background music, public address systems, and more. Ideal for environments such as bars, restaurants, retail locations, hotels, corporate spaces, and educational facilities, the CMA1202 offers both Low-Z (4/8 Ohm) and High-Z (70V/100V) loudspeaker configurations, providing exceptional versatility to meet diverse installation requirements. With a focus on ease of use, this amplifier is designed to be simple to install and operate, even for non-technical personnel.

Equipped with a wide array of input options, the CMA1202 features 8 mic/line inputs with individual volume controls, providing ample flexibility for managing various audio sources. The amplifier includes 2 x 5-pin Euroblock connectors for priority or ducking mic inputs, which ensure that announcements or priority audio always take precedence over background music. Additionally, there are 6 x 3-pin Euroblock connectors and 6 x RCA inputs, offering the ability to connect both balanced and unbalanced audio sources, such as mixers, phones, computers, or other media devices. The amplifier's flexibility is further enhanced with intuitive output routing, allowing for seamless audio distribution across multiple areas or zones.

One of the standout features of the CMA1202 is its ability to integrate modern streaming and playback technology. With built-in Bluetooth streaming, the amplifier can easily connect to any Bluetooth-enabled device such as smartphones, tablets, or laptops, allowing for wireless music playback without the need for outdated cables or adapters. In addition, the CMA1202 is equipped with a USB media player, complete with an intuitive LCD navigation interface that allows users to play audio files directly from a USB stick. This eliminates the need for external players and simplifies the playback process, making it ideal for venues that rely on digital media.

The CMA1202 also incorporates advanced energy-saving features to reduce operating costs and improve environmental sustainability. Thanks to its direct drive constant power technology, the amplifier delivers reliable performance while conserving energy. It includes an Auto Ramp circuit that automatically powers the amplifier on or off based on the presence of an input signal. After 20 minutes of inactivity, the system enters sleep mode to conserve power, and as soon as the Auto Ramp circuit detects a signal, it powers back up seamlessly. This feature ensures that the amplifier is energy-efficient without sacrificing performance.

Designed for easy installation and versatile use, the CMA1202 features a 1U, 19" rack-mountable enclosure. With rubber feet included, the amplifier can be placed on desks or shelves without additional mounting hardware, but it also includes optional rack mounting brackets for more permanent installations. The unit can be mounted in a half or full rack space, or even installed under tables or on walls, depending on the needs of the user. Additionally, the CMA1202 operates quietly, with a fanless convection-cooled design that minimizes noise and disruption in sensitive environments.

The CMA1202's intuitive front panel includes easy-to-access controls for master volume, bass, and treble adjustments. Each channel features individual gain controls, allowing the user to fine-tune audio levels to suit the needs of each zone or input. The amplifier also includes priority muting and chime functions, which automatically override background music when an announcement is made. With a remote control option via RJ-45 Ethernet connectors, the CMA1202 can be integrated into a larger audio system and controlled remotely via compatible controllers like the CRC-V Series or the LAB.LEVEL tabletop controller.

The CMA1202 is built with safety in mind, offering thermal, overcurrent, and DC protection to prevent damage under extreme conditions. The amplifier also includes load protection, ensuring reliable operation even during power surges or drops. With a frequency response of 20 Hz to 20 kHz and low distortion, the CMA1202 delivers clear and accurate audio reproduction, making it an ideal choice for any professional audio installation.
