Lab Gruppen CMA1202 2 x 120W Commercial Mixer Amplifier with 8 Inputs - CMA1202

Product Overview

The Lab Gruppen CMA1202 is a 2-channel, 2x120W commercial mixer amplifier with an integrated 8-input mixer, designed for permanent installation in small to mid-size commercial distributed audio systems. It consolidates mixing and amplification into a single half-rack 1U unit, making it a cost-effective and space-efficient solution for two-zone background music in retail, hospitality, corporate, and institutional environments. The CMA1202 supports both 4/8 ohm and 70V/100V constant-voltage speaker configurations.

Product Description

The CMA1202 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 via rear-panel dipswitch. Its 8-input mixer section includes six balanced mic/line inputs via Euroblock connectors and two additional line inputs, each with individual volume controls. Rear-panel input routing dipswitches allow each input to be independently assigned to Output A, Output B, or both zones simultaneously, providing flexible coverage without additional signal routing hardware. Front-panel master volume, bass, and treble controls for each output zone allow on-site adjustments by facility personnel. Priority muting on Input A reduces background music levels automatically when a paging or announcement signal is detected. Fanless convection cooling ensures silent operation in noise-sensitive commercial spaces, and Auto Ramp circuitry with a 20-minute sleep timer supports Energy Star energy efficiency requirements. The unit ships with joining brackets for rack, wall, or table mounting.

Frequently Asked Questions

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

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

Q: Can the CMA1202 drive 70V distributed speaker lines?

A: Yes. Each output channel is independently switchable between low-impedance (4/8 ohm) and high-impedance (70V/100V) constant-voltage via rear-panel dipswitch, with no external transformer required.

Q: How are the 8 inputs routed to the two output zones?

A: Rear-panel dipswitches control routing. By default, Inputs A–D route to Output A and Inputs E–H route to Output B. Each input can be individually reassigned to route to Output A, Output B, or both zones simultaneously.

Q: Can the CMA1202 accept microphone-level signals?

A: Yes. Six of the eight inputs are balanced mic/line Euroblock connectors that accept both microphone-level and line-level signals. Input A also includes priority muting for paging applications.

Q: Is the CMA1202 suitable for rack mounting in a standard 19-inch rack?

A: Yes. The half-rack 1U unit includes joining brackets that allow two CMA1202 units to share a single 1U rack space, or each unit can be rack-, wall-, or table-mounted individually.

Q: What is the idle power consumption of the CMA1202?

A: The Auto Ramp sleep mode activates after 20 minutes of no input signal, significantly reducing idle power consumption. The unit is Energy Star certified, confirming it meets commercial energy efficiency thresholds for commercial audio equipment.
