LAB GRUPPEN CPA1202 2 x 120W Commercial Mixer Amplifier with 8 Inputs, Bluetooth (CPA1202)

The CPA1202 sounds like an excellent fit for various commercial and industrial environments! Its 2 x 120-watt capacity, coupled with its ability to cater to both Low-Z and High-Z loudspeaker configurations, offers remarkable flexibility for delivering high-quality audio. The user-friendly installation and operation make it accessible even for non-technical personnel, making it suitable for venues like bars, restaurants, retail stores, hotels, corporate spaces, educational institutions, and more that require background music or a public address system.

Easy to Hook Up

The CPA1202 offers a modern and versatile solution for accessing audio. With Bluetooth connectivity, users can effortlessly stream music wirelessly from their smartphones, tablets, or laptops. Additionally, the USB media player with an easy-to-navigate LCD screen allows for direct playback of audio files from a USB stick. The provision of a standard 3-pin Euroblock Input socket caters to balanced sources like mixers or audio processors, while RCA cables offer connectivity for unbalanced stereo sources like players, phones, or computers (note that only one input source should be used at a time). Finally, loudspeaker output is facilitated through a standard 2-pin Euroblock socket, ensuring compatibility with various loudspeaker configurations.

Easy to Install

The CPA1202 provides multiple mounting options for seamless integration into different setups. Its rubber feet allow for easy placement on desks or shelves without the need for additional installation. Additionally, the included optional rack mounting hardware offers versatile installation configurations. Whether it's housing a single product in a half 19" rack or a full rack enclosure, or mounting a pair of amplifiers side-by-side in a single rack space, these options provide adaptability to diverse setups. Moreover, the included brackets enable wall mounting or mounting under a table or shelf, enhancing its flexibility for placement and installation in various environments.

Automatic Power On/Off

The CPA1202's power scheme sounds quite intuitive and efficient. Its automatic power on/off based on the input signal is a smart feature that optimizes energy consumption. Entering sleep mode after 20 minutes of no input signal, it ensures reduced power consumption during idle periods. When a signal is detected, the Auto Ramp circuit swiftly restores the system to normal operation, ensuring quick responsiveness to input signals. Additionally, the ability to manually force the amplifier into standby mode or awaken it using the front panel power button offers convenient control over its power state, allowing for tailored usage based on needs.

Sublimely Simple Controls

CPA1202’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.

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 Ω, or 4 Ω 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 CPA1202 is part of a family of products that provides both single and dual-zone products that are perfect for building out a system of any size. With its individual zone volume and remote control capabilities, the CPA1202 is an ideal building block for a dynamic and scalable system solution.

Real-World Energy Savings

The CPA1202 2 x 120 Watt Commercial Amplifier makes it easy to bring the 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 CPA1202 can generate enough energy savings to pay for itself in virtually no time at all.
