Lab Gruppen CPA1202 2 x 120W Commercial Mixer Amplifier with 8 Inputs, Bluetooth

Product Overview

The Lab Gruppen CPA1202 is a 2-channel, 2x120W commercial mixer amplifier with an 8-input mixer section, integrated Bluetooth streaming, and a USB media player, designed for permanent installation in small to mid-size commercial distributed audio systems. It provides all the signal processing, source selection, and amplification needed for a complete two-zone background music system in a single half-rack 1U unit, making it a practical choice for integrators fitting commercial audio into tight equipment spaces. The CPA1202 supports both low-impedance and 70V/100V constant-voltage speaker configurations.

Product Description

The CPA1202 delivers 120 watts per channel across two independently controlled output zones, each switchable between low-impedance (4/8 ohm) and high-impedance (70V/100V) constant-voltage operation. Its 8-input mixer provides six balanced mic/line Euroblock inputs and two line inputs, each with individual volume controls. An integrated Bluetooth receiver allows wireless audio streaming from smartphones, tablets, or computers, while the built-in USB media player with LCD display provides standalone audio playback from USB storage. Front-panel master volume, bass, and treble controls for each output zone allow quick on-site adjustments by facility managers without rack access. Priority muting on Input A automatically reduces background music when a paging or announcement signal is detected, supporting public address use cases in retail, hospitality, and commercial building environments. A configurable input routing dipswitch on the rear panel assigns each of the 8 inputs to Output A, Output B, or both zones. Fanless convection cooling provides completely silent operation for noise-sensitive spaces including offices and hotel lobbies. Auto Ramp circuitry and a 20-minute sleep timer support Energy Star energy efficiency in spaces with variable occupancy schedules.

Frequently Asked Questions

Q: What is the difference between the CPA1202 and the CMA1202?

A: Both are 2x120W 8-input commercial mixer amplifiers. The CPA1202 adds integrated Bluetooth streaming and a USB media player. The CMA1202 is the analog-only version, suited for installations where a separate source device or DSP handles audio source selection.

Q: Can the CPA1202 power 70V distributed speaker systems?

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

Q: How many speakers can each output channel support at 70V?

A: The total wattage of speaker tap settings connected to each output channel must not exceed 120W. For example, twelve 10W tap speakers per channel would be at the channel's rated power.

Q: Does the Bluetooth input support priority muting?

A: Priority muting acts on all background sources when Input A carries a priority signal. Bluetooth and USB playback will both be reduced in level during a priority event.

Q: Is the CPA1202 suitable for installation in a 19-inch equipment rack?

A: Yes. It is a 1U half-rack unit. Two units can be joined side-by-side using the included brackets to occupy one full 1U rack space, or it can be mounted individually in rack, wall, or table configurations.

Q: Can the USB media player and Bluetooth sources be used with different output zones?

A: The USB and Bluetooth inputs are selectable media sources. Their routing to output zones is controlled by the rear-panel input routing dipswitches, the same as any other input channel.
