Lab Gruppen CA2402 2 x 240W Commercial Amplifier with Energy Star Certification

Product Overview

The Lab Gruppen CA2402 is a 2-channel, 2x240W commercial power amplifier with Energy Star certification, designed for permanent installation in high-power distributed audio systems across retail, hospitality, corporate, and institutional environments. It accepts balanced analog signals from an upstream DSP or mixer and delivers 70V/100V constant-voltage or low-impedance audio to commercial speaker systems, making it a reliable two-zone amplification endpoint in professionally designed commercial AV installations. The CA2402 is convection-cooled, fanless, and supports multiple mounting configurations.

Product Description

The CA2402 provides 240 watts per channel across two independently switchable output channels, each configurable for low-impedance (4/8 ohm) or high-impedance (70V/100V) constant-voltage speaker loads via rear-panel dipswitch. Balanced analog inputs via Euroblock connectors accept signals from commercial DSPs, zone controllers, and mixer amplifiers, integrating cleanly into structured AV system architectures. Simple rear-panel dipswitch controls allow installers to set output voltage and input gain without front-panel menus or software. An 80Hz high-pass filter is switchable per channel to protect ceiling and pendant speakers from low-frequency content. Auto Ramp circuitry activates the CA2402 automatically when input signal is detected and transitions to sleep mode after 20 minutes of inactivity, keeping energy consumption within Energy Star thresholds and reducing operating costs in spaces with variable daily schedules. Fanless convection cooling provides completely silent operation in offices, hotel lobbies, and conference rooms where mechanical fan noise would be unacceptable. Multiple mounting options including rack, table, and wall brackets are included in the box. The CA2402 is an appropriate choice when a dedicated mixing or DSP unit handles source selection and signal processing upstream.

Frequently Asked Questions

Q: Does the CA2402 include a built-in mixer?

A: No. The CA2402 is a power amplifier only and accepts one balanced analog input per channel. For mixing multiple microphone or line-level sources, use a CMA or CPA series mixer amplifier, or pair the CA2402 with a separate commercial mixer or DSP upstream.

Q: Can the CA2402 power 70V speaker systems without an external transformer?

A: Yes. Each output channel can be switched to 70V or 100V constant-voltage operation via rear-panel dipswitch. No external output transformer is required; standard 70V tap transformers at each speaker are still needed.

Q: How is the CA2402 configured for different output voltages and gain settings?

A: Output voltage (4/8 ohm, 70V, or 100V) and input gain are set using rear-panel dipswitches, providing straightforward configuration without software or front-panel menus.

Q: What upstream equipment does the CA2402 work with?

A: The CA2402 accepts balanced line-level signals from commercial DSPs, zone controllers, matrix mixers, and mixer amplifiers with balanced line outputs. It is commonly used as an amplification endpoint in DSP-based commercial AV systems.

Q: Is the CA2402 quiet enough for use in conference rooms and offices?

A: Yes. The CA2402 uses fanless convection cooling with no moving parts, producing zero mechanical noise during operation.

Q: Does the CA2402 power down automatically when not in use?

A: Yes. Auto Ramp circuitry monitors the input signal and transitions the unit to a low-power sleep mode after 20 minutes of inactivity, then resumes normal operation automatically when signal returns.
