Lab Gruppen CPA2401 240W Commercial Mixer Amplifier with 5 Inputs, Bluetooth

Product Overview

The Lab Gruppen CPA2401 is a single-channel, 240W commercial mixer amplifier with a 5-input mixer section, integrated Bluetooth streaming, and a USB media player, designed for commercial spaces requiring a high-power mono distributed audio system. It is well suited for large single-zone applications including retail showrooms, restaurant dining areas, house of worship overflow rooms, and commercial lobbies where maximum mono output power and multiple source inputs are required in a compact half-rack unit. The CPA2401 supports both low-impedance and 70V/100V constant-voltage speaker loads.

Product Description

The CPA2401 delivers 240 watts into a single output channel, switchable between low-impedance (4/8 ohm) and high-impedance (70V/100V) constant-voltage operation via rear-panel dipswitch. Its 5-input mixer includes balanced mic/line Euroblock inputs and line-level inputs with individual volume controls, providing enough source flexibility for most single-zone commercial audio applications without requiring a separate mixer. Integrated Bluetooth allows wireless streaming from mobile devices, and the USB media player with LCD display provides standalone playback from USB storage, making the CPA2401 a self-contained source and amplification solution. Front-panel volume, bass, and treble controls allow quick adjustments by on-site facility staff. Priority muting on Input A automatically reduces background music levels when a paging or announcement microphone signal is detected, a common requirement for retail, hospitality, and public facility deployments. Fanless convection cooling eliminates mechanical noise, and Auto Ramp circuitry with a 20-minute sleep timer keeps power consumption within Energy Star certification thresholds. The unit ships with joining brackets for 1U half-rack, wall, or table mounting.

Frequently Asked Questions

Q: What is the difference between the CPA2401 and the CPA2402?

A: The CPA2402 is a 2-channel unit delivering 240W per channel across two independent zones. The CPA2401 combines all 240W into a single output channel for maximum power in one zone, making it the better choice for large single-zone spaces.

Q: Can the CPA2401 drive a 70V distributed speaker system?

A: Yes. The output channel is switchable between low-impedance (4/8 ohm) and high-impedance (70V/100V) constant-voltage operation via rear-panel dipswitch.

Q: How many speakers can the CPA2401 support on a 70V circuit?

A: The total wattage of all speaker tap settings on the 70V circuit must not exceed 240W. For a typical commercial installation with 8W speaker taps, up to 30 speakers could be supported within the power budget.

Q: Does the CPA2401 require professional installation?

A: While the CPA2401 can be configured by a knowledgeable end user, commercial AV integration by a qualified installer is recommended for rack mounting, 70V speaker system design, and proper input wiring using Euroblock connectors.

Q: Is the Bluetooth range suitable for commercial spaces?

A: The Bluetooth receiver is designed for proximity use, typically within 30 feet, appropriate for a staff member streaming background music from a nearby mobile device. It is not intended as a long-range distribution solution.

Q: What happens when a priority input signal is detected?

A: When a signal is detected on Input A (the priority input), all other background sources including Bluetooth and USB playback are automatically reduced in level, allowing the priority announcement or page to be clearly heard.
