Lab.Gruppen CMA1202 8-Input Commercial Mixer Amplifier

Lab.Gruppen CMA1202 Overview

Add ambiance to your store or restaurant with the Lab.Gruppen CMA1202, a commercial mixer amplifier that's the perfect solution for commercial and industrial applications requiring great sounding distributed audio coupled with power conservation and reduced operating expense. The 8-input mixer features independent volume controls on the front panel as well as individual front panel master volume and bass/treble controls for each output.

The CMA1202 features two 120W channels that are capable of delivering high-quality sound over both Low-Z (4/8 ohms) and High-Z (70/100V) loudspeaker configurations, offering flexibility on every channel. CMA1202 is easy to install and operate, even for non-technical personnel. It is ideally suited for bars, restaurants, retail destinations, hotels, corporate, education or other venues needing background music and/or a public address system.

Easy to Install

The CMA1202 comes equipped with rubber feet, enabling the amps to be placed on a desk, shelf or any clear surface without any additional installation requirements. However, optional rack mounting hardware is also supplied, allowing one or several models to be housed and protected inside an enclosure. This adds extensive flexibility as a single product can be housed in a half 19" rack or full rack enclosure as well as a pair of amplifiers can easily be mounted side-by-side in a single rack space. With the included brackets the unit can also be mounted to a wall or under a table/shelf.

Automatic Power On/Off

The CMA1202 has a flexible power scheme with seamless and automatic power on/off based on the input signal, which reduces consumption when a signal is not present. With virtually zero configuration required, an energy smart and hassle-free amplifier system can easily be set up for hands-off operation. If the CMA1202 is powered on but does not receive an input signal for 20 minutes, the system automatically enters sleep mode to reduce power consumption. As soon as the Auto Ramp circuit detects a signal, the system powers on and normal operation resumes. The amplifier can also be instantly forced into standby mode or awakened via the front-panel power button.

Simple Controls

CMA1202's controls are sublimely intuitive, allowing the operator to quickly make adjustments. The front-panel power button and Master volume knob are easily accessible, enabling virtually anyone to operate the system. Bass and Treble controls are also available for fine tuning, but require a tool when making changes.

Easy to Hook Up

For connecting a balanced source such as a mixer or audio processor, a standard 3-pin Euroblock Input socket is provided. Alternatively, RCA cables can be connected for unbalanced stereo sources (summed to mono), such as players, phones or computers, however only one input source should be used at a time. Loudspeaker Output is provided in the form of a standard 2-pin Euroblock socket.

Output Configuration

Intuitive configuration of the flexible outputs is provided directly adjacent to the rear panel Euroblock output connectors with dipswitches, which allow selection of 100 V, 70 V, 8 ohms, or 4 ohms operation individually per channel. This configures both the maximum voltage of the output and the gain through the device. An individual control engages the built-in high-pass filter, which should be used on all constant voltage systems to avoid saturation on transformer-enabled loudspeakers and to help maintain sound integrity.

Expandable Remote Control

The RJ45 receptacle on the rear panel opens up a broad range of remote control options, including the CRC-V Series of wall controllers and a stylish tabletop controller, the LAB.LEVEL. All can be interconnected via inexpensive and readily available Ethernet cabling.

System Scalability

Commercial installs vary widely in scope and often grow and change over time. The CMA1202 is part of a family of products that provides both single and dual zone products that are perfect for building out a system to any size. With its individual zone volume and remote control capabilities, the CMA1202 is an ideal building block for a dynamic and scalable system solution.

Real-World Energy Savings

The CMA1202 2 x 120 watt Commercial Amplifier makes it easy to bring highest-quality music and announcements to business and industrial environments in an easy to integrate, and even easier to operate system. Plus, with features such as its Auto Ramp and revolutionary direct drive constant power technology, the energy efficient CMA1202 can generate enough energy savings to pay for itself in virtually no time at all.
