LAB GRUPPEN CMA1201_US1 120W Commercial Mixer Amplifier with 4 Inputs (CMA1201)
The CMA1201, a 120-watt commercial Mixer Amplifier, is an exceptional solution for commercial and industrial settings seeking top-notch distributed audio while emphasizing energy efficiency and reduced operational costs. With the capability to deliver superior sound across both Low-Z (4/8 Ohm) and High-Z (70/100 V) loudspeaker configurations, this amplifier offers unparalleled flexibility on every channel.
Ease of Installation:
Equipped with rubber feet for versatile placement, the CMA1201 requires no additional installation requirements on desks, shelves, or other clear surfaces. Additionally, it includes optional rack mounting hardware, providing diverse enclosure options for single or paired amplifiers.
Efficient Power Management:
The amplifier features an intelligent power scheme that automatically activates or deactivates based on the input signal, minimizing power consumption during signal absence. This hassle-free system setup requires minimal configuration and can enter sleep mode after 20 minutes of signal inactivity, reactivating promptly upon detecting a signal.
User-Friendly Controls and Connectivity:
The CMA1201 boasts intuitive controls, including easily accessible power buttons, Master volume knobs, Bass/Treble controls, and input/output sockets for balanced or unbalanced sources. These controls are designed for seamless operation, though tool-assisted adjustments are required for Bass/Treble tuning.
Flexible Output Configuration:
Adjacent to the rear panel Euroblock output connector, the amplifier provides intuitive configuration options through dipswitches. These allow the selection of voltage operation (100 V, 70 V, 8 Ω, or 4 Ω) and gain adjustments for maintaining sound integrity, including a high-pass filter for constant voltage systems.
Remote Control Capabilities:
Featuring an RJ45 receptacle, the amplifier enables a wide range of remote control options, such as compatibility with wall controllers like the CRC-V Series and the stylish tabletop controller, the LAB LEVEL. All these devices interconnect seamlessly using affordable Ethernet cabling.
Scalability and Energy Efficiency:
As part of a versatile product family offering single and dual-zone solutions, the CMA1201 serves as a fundamental component for constructing dynamic and scalable audio systems. Its individual zone volume control and remote capabilities contribute to system scalability, while energy-efficient features like Auto Ramp and direct drive constant power technology yield significant energy savings, potentially offsetting costs efficiently.
