Lab Gruppen CA1201 - 120W 1-Channel at 4-Ohm 70V/100V Commercial Amplifier with Euroblock Outputs and Energy Star Certification in Black Finish

The Lab Gruppen CA1201 is a versatile 120-watt, 1-channel commercial amplifier, specifically designed to meet the audio demands of commercial and industrial environments. Perfect for applications such as bars, restaurants, retail spaces, hotels, corporate offices, and educational facilities, the CA1201 provides clear, high-quality sound for background music and public address systems. This amplifier is capable of driving both Low-Z (4/8 Ohm) and High-Z (70V/100V) loudspeakers, offering flexibility for a wide range of speaker configurations, making it an ideal solution for diverse installation requirements.

At the heart of the CA1201's performance is its energy-efficient design, which has earned it Energy Star certification. This certification reflects the amplifier's ability to conserve energy while delivering exceptional audio quality. The CA1201 uses Lab Gruppen's direct drive constant power technology, which ensures superior sound performance and reliability, even in demanding environments. By consuming less power compared to other models, the CA1201 helps reduce operational costs, making it an environmentally-friendly choice that also saves on electricity bills. Its efficiency allows it to operate seamlessly with existing infrastructure, reducing installation costs and simplifying setup.

Designed for ease of installation and operation, the CA1201 offers intuitive controls that are accessible even to non-technical users. The amplifier features a front panel with a power standby button, master volume control, and tone adjustments for bass and treble. For more precise adjustments, the tone controls can be fine-tuned using a tool. The rear panel includes a 3-pin Euroblock input socket for balanced audio sources like mixers or processors, and RCA inputs for unbalanced stereo sources. The Euroblock output connector supports various loudspeaker configurations, and the rear panel also features dipswitches for selecting between 100V, 70V, 8Ω, or 4Ω operation, along with an 80Hz high-pass filter to protect transformer-driven loudspeakers from saturation.

The amplifier's energy-saving features include Auto Ramp circuitry, which ensures fast, quiet power-up and shut-down to conserve power when no signal is present. If no input signal is detected for 20 minutes, the amplifier automatically enters sleep mode, minimizing energy consumption further. The system is also designed to be energy-smart, with minimal configuration required for straightforward, hands-off operation. The CA1201 can be forced into standby mode or awakened via the front panel or remotely using the included RJ45 connector, which allows for connection to remote volume controls such as the CRC-V Series wall controllers or the LAB.LEVEL tabletop controller.

For added flexibility, the CA1201 is equipped with mounting hardware that allows it to be installed in a variety of configurations. It can be rack-mounted in a half-rack or full-rack enclosure, or mounted on a desk, shelf, or even under a table. The convection-cooled, fanless design ensures that the amplifier operates quietly, without the need for a fan, making it suitable for noise-sensitive environments. Furthermore, the amplifier includes a full range of protection features, including thermal, over-current, DC, and high-frequency protection, ensuring reliable and safe operation in even the most demanding applications.
