Lab Gruppen CA1202 - 120W 2-Channel at 4-Ohm 70V/100V Commercial Amplifier with Euroblock Outputs and Energy Star Certification in Black Finish

The Lab Gruppen CA1202 is a highly efficient and powerful 2-channel commercial amplifier, designed to provide superior sound quality in a variety of commercial and industrial environments. Ideal for applications such as background music and public address systems, the CA1202 delivers 120 watts per channel and is flexible enough to support both Low-Z (4/8 Ohm) and High-Z (70V/100V) speaker configurations. Whether installed in retail spaces, hotels, restaurants, or educational facilities, the CA1202 offers an ideal solution for distributing high-quality audio with exceptional energy efficiency. Its Energy Star certification makes it a cost-effective choice for environments where minimizing operational costs is a priority.

The CA1202's direct drive, constant power technology ensures reliable audio performance while reducing energy consumption. This amplifier utilizes a robust Class D output circuit, delivering high power with low heat generation, which results in quieter operation and energy savings. It features an 80Hz high-pass filter, which helps to prevent saturation in transformer-driven loudspeakers, preserving sound clarity in constant voltage systems. With a built-in automatic power-on and sleep mode, the CA1202 conserves power when no signal is present, ensuring that energy is only used when necessary. After 20 minutes without an input signal, the amplifier automatically enters sleep mode, and instantly resumes operation when it detects a signal again. This advanced feature significantly reduces operational costs and prolongs the life of the unit.

The amplifier is designed for ease of use, with intuitive front-panel controls, including a power standby button, master volume, and bass/treble adjustments. These controls are simple enough for non-technical personnel to operate. For more advanced users, the rear panel offers additional configuration options, including the ability to switch between 4Ω, 8Ω, 70V, or 100V operation, as well as the option to engage the high-pass filter. The amplifier also provides flexible connection options, with two 3-pin Euroblock inputs for balanced sources and RCA inputs for unbalanced sources. Output is provided through a 4-pin Euroblock connector, offering secure and reliable connections to the speakers.

In terms of installation, the CA1202 is highly versatile. It comes with rubber feet for easy placement on desks, shelves, or tables, but also includes optional rack mounting hardware for a 1U, half-rack width setup. This makes it suitable for both standalone and multi-unit configurations, and it can be easily mounted to a wall or under a table if necessary. The amplifier's fanless, convection-cooled design ensures quiet operation, making it perfect for noise-sensitive environments. Additionally, the system features several protection mechanisms, including thermal, overcurrent, DC, and high-frequency protection, ensuring safe and reliable operation in a variety of conditions.
