Lab Gruppen CPA2402 Power Amplifier for Installations

Commercial Mixer Amplifier for Distributed Audio Installations

The Lab Gruppen CPA2402 is a 2x240W commercial mixer amplifier built for distributed audio in bars, restaurants, hotels, retail spaces, and conference rooms. Each channel delivers 240 watts and can be independently configured for Low-Z (4/8 ohm) or High-Z (70/100V) loudspeaker operation via rear-panel dip switches, giving installers the flexibility to drive conventional speakers or constant-voltage distributed systems from a single 1U unit. The CPA2402 is the right choice for AV installers and venue operators who need a compact, all-in-one amplifier/mixer that handles multiple sources without outboard gear.

Integrated Mixer, Media Player, and Remote Control

What sets this model apart from a basic rack amp is the integrated 8-input mixer with per-channel volume, mic/line sensitivity switching, and 48V phantom power for condenser microphones. A front-panel LCD media player accepts USB thumb drives for direct audio playback, while Bluetooth 4.2 streams audio wirelessly from phones or tablets at a range of up to 13.7 m. The RJ45 GPI port accepts Lab Gruppen's CRC-V wall controllers and the LAB.LEVEL tabletop controller over standard Ethernet cabling, letting staff adjust volume from a different room without walking to the rack.

Amplifier Performance and Installation Specs

The Class-D amplifier stage uses direct drive constant power technology for clean output across the full audio band: 20 Hz to 20 kHz frequency response, signal-to-noise ratio above 95 dB, and total harmonic distortion below 0.5% at 1/8 rated power. A switchable 80 Hz high-pass filter protects transformer-coupled loudspeakers from saturation, while per-channel 2-band shelving EQ lets installers tune each zone. The fanless convection-cooled chassis measures 437 x 46 x 249 mm and weighs 3.6 kg, fitting a standard 1U rack slot with the included mounting brackets.

Ideal for AV Installers and Commercial Venue Operators

The CPA2402 suits AV system integrators and venue staff who need a turnkey amplifier/mixer for small to mid-sized commercial installations. It works well in hospitality, retail, corporate boardrooms, houses of worship, and education facilities where multiple audio sources — microphones, streaming devices, USB media, paging — must coexist on a single amplifier. Fanless convection cooling suits noise-sensitive environments such as conference rooms and libraries, while Energy Star certification and Auto Ramp sleep mode keep operating costs low in 24/7 installations. Non-technical staff can operate the front-panel master volume and power button without training, while installers retain full configuration access via rear-panel dip switches and the RJ45 remote port.
