Lab Gruppen CMA602 - 60W 2-Channel at 4-Ohm Commercial Mixer Amplifier with 2 x 5-Pin Euroblock and 6 x 3-Pin Euroblock/RCA Inputs in Black Finish

The Lab Gruppen CMA2402 is a 2 x 240W commercial mixer amplifier designed for demanding commercial and industrial applications that require high-quality audio and energy efficiency. Perfectly suited for environments like bars, restaurants, retail destinations, hotels, corporate spaces, and educational institutions, the CMA2402 excels in both background music and public address systems. Offering exceptional versatility, the amplifier supports both Low-Z (4/8 Ohm) and High-Z (70V/100V) loudspeaker configurations, allowing for seamless integration into a wide range of audio setups. It's the ideal choice for venues needing reliable and clear audio distribution across multiple areas.

The CMA2402 features eight audio input channels with individual volume controls for precise management of each signal. The unit provides 2 x 5-pin Euroblock connectors for priority or ducking mic/line inputs, ensuring announcements take precedence over background music. In addition, there are 6 x 3-pin Euroblock connectors and 6 x RCA inputs, allowing for both balanced and unbalanced connections, giving users flexibility in integrating various audio sources. The unit also includes intuitive output routing, making it easy to distribute audio across multiple zones or locations.

Designed with ease of operation in mind, the CMA2402 includes front panel controls that allow for quick adjustments to the master volume, bass, and treble. These controls are easily accessible, ensuring that operators can make adjustments without hassle. The amplifier also features a priority muting function that automatically reduces or mutes the background music when an announcement is made, ensuring that important audio signals are always heard clearly. For enhanced convenience, the CMA2402 supports remote control via an RJ-45 connector, enabling the integration of additional remote volume controls like the LAB.LEVEL tabletop controller or CRC-V Series wall controllers.

Energy efficiency is a core feature of the CMA2402. Utilizing direct drive constant power technology, the amplifier delivers consistent, high-quality audio performance while minimizing power consumption. This energy-efficient design, coupled with the amplifier's Energy Star certification, ensures that the CMA2402 helps businesses lower operational costs. The amplifier also incorporates Auto Ramp circuitry, automatically powering on or off based on the presence of an input signal. This feature helps to save energy when the amplifier is not in use, and it enters sleep mode after 20 minutes of inactivity. Upon detecting a signal again, the amplifier powers up, ensuring it's always ready when needed.

The CMA2402 is housed in a robust 1U, 19" rack-mountable enclosure, designed for easy installation. Rubber feet are included, allowing the amplifier to be placed on a desk, shelf, or other surfaces without additional mounting requirements. The amplifier can also be mounted in a rack, with the option to house one or more units in a half-rack or full-rack enclosure. The unit can also be mounted to walls or under tables, offering maximum flexibility for a variety of installation needs. Its fanless, convection-cooled design ensures quiet operation, making it ideal for environments where noise sensitivity is a concern.

With comprehensive protection features like thermal, overcurrent, DC, and high-frequency protection, the CMA2402 guarantees reliable and safe operation even in demanding environments. The amplifier also offers load protection with controlled start and shutdown behavior, preventing damage from sudden changes in power. This makes it a dependable choice for businesses and institutions that rely on consistent, high-performance audio systems.
