Lab Gruppen CPA2402 2 x 240 Watt Commercial Mixer Amplifier with 8 Inputs, Bluetooth Streaming, USB Media Player

Product Overview

The Lab Gruppen CPA2402 is a 2-channel, 2x240W commercial mixer amplifier designed for permanent installation in commercial audio distribution systems. It combines an 8-input mixer section with integrated Bluetooth streaming and a USB media player, making it a complete front-end and power solution for background music systems in retail, hospitality, and corporate environments. Ideal for integrators specifying a single-rack-unit commercial mixer amplifier with wireless audio capability.

Product Description

The CPA2402 delivers 240 watts per channel across two independently controllable output zones, supporting both low-impedance (4/8 ohm) and high-impedance (70V/100V) constant-voltage speaker configurations without external transformers. Its 8-input mixer section includes six balanced mic/line inputs via Euroblock connectors and two line inputs, each with individual volume controls and output routing via rear-panel dipswitches. The integrated Bluetooth receiver allows wireless audio streaming from mobile devices, while the USB media player with LCD display provides standalone playback from USB storage. Front-panel master volume, bass, and treble controls for each output channel enable quick adjustment without rear-panel access. Convection cooling eliminates fan noise, making the CPA2402 appropriate for quiet office environments, boardrooms, and hospitality spaces. Auto Ramp circuitry brings the amplifier on smoothly when signal is detected and transitions to sleep mode after 20 minutes of inactivity, reducing energy consumption and supporting Energy Star compliance. The half-rack form factor ships with joining brackets for rack, table, or wall mounting, giving installers flexibility in equipment placement. Priority muting on Input A allows paging or emergency audio to automatically reduce background music levels, a critical feature for public address applications in retail and commercial buildings.

Key Features

• 2x240W Dual-Zone Output — Independently powers two speaker zones at up to 240W per channel across 4/8 ohm or 70V/100V loads.
• 8-Input Mixer Section — Six balanced mic/line Euroblock inputs and two line inputs with individual volume controls and configurable channel routing.
• Integrated Bluetooth Streaming — Receives wireless audio from smartphones, tablets, or laptops for background music without additional hardware.
• USB Media Player with LCD Display — Plays audio directly from USB storage devices, eliminating the need for a dedicated source component.

Frequently Asked Questions

Q: Can the CPA2402 drive 70V speaker systems directly?

A: Yes. Each output channel can be switched between low-impedance (4/8 ohm) and high-impedance (70V/100V) operation via rear-panel dipswitch, eliminating the need for an external output transformer.

Q: How many independent audio zones can the CPA2402 support?

A: The CPA2402 supports two independently controlled output zones, each with its own master volume, bass, and treble adjustments. Inputs can be routed to one or both zones using the rear-panel routing dipswitches.

Q: Does the Bluetooth input support priority muting?

A: Priority muting is configured on Input A (the primary mic/line input), which will automatically reduce the level of background sources including Bluetooth when a signal is present on that input.

Q: Is the CPA2402 suitable for installation in a standard 19-inch equipment rack?

A: Yes. The CPA2402 is a 1U half-rack unit. Two units can be joined side by side to fill a full 1U rack space using the included joining brackets, or it can be rack-, wall-, or table-mounted individually.

Q: Does the CPA2402 require any special wiring for 70V distributed audio?

A: No transformer is required. The amplifier's Direct Drive topology outputs 70V or 100V directly. Standard commercial in-wall wiring and 70V-rated speakers with tap transformers complete the system.

Q: What happens when no audio signal is present?

A: The Auto Ramp circuit monitors input signal level. After 20 minutes of inactivity, the CPA2402 enters sleep mode to reduce power draw, then powers back on automatically when signal resumes.

Q: Can the USB media player and Bluetooth be used simultaneously?

A: The USB and Bluetooth inputs are selectable sources on the media player section. Only one can be active at a time, selected via the front-panel LCD interface.
