Lab Gruppen CM41 Commercial Mixer with 4 Inputs

Product Overview

The Lab Gruppen CM41 is a 4-input, 1-output commercial mixer designed for permanent installation in commercial audio systems where a compact, single-output mixing stage is needed ahead of a power amplifier or powered speaker system. It provides four individually controlled mic/line inputs and a single mix output, making it a practical and cost-effective front-end mixing solution for single-zone background music and paging systems in retail, hospitality, office, and institutional environments. The CM41 is a standalone mixer with no built-in amplification.

Product Description

The CM41 provides four mic/line inputs with individual volume controls, accepting balanced signals from microphones and line-level sources via Euroblock and RCA connectors. A single mix output carries the combined signal to a downstream power amplifier, DSP, or zone controller. A configurable priority muting function automatically reduces background music levels when a paging or announcement signal is detected on the designated priority input, supporting basic public address requirements in retail and commercial building environments. Front-panel power control allows the mixer to be powered on or off without rear-panel access, convenient for installations where the mixer is accessible to facility staff. Frequency response of 20 Hz to 20 kHz with less than 0.05% THD maintains audio quality across the full audio band for commercial background music applications. The CM41 is designed for permanent 19-inch rack installation and integrates cleanly with Lab Gruppen CA, FA, and other commercial power amplifiers in structured single-zone commercial audio systems. An auxiliary output provides an additional send for recording, monitoring, or routing to a secondary destination.

Key Features

• 4 Mic/Line Inputs — Individually controlled inputs accept microphones and line-level sources for flexible single-zone source mixing.
• Single Mix Output — Feeds a single downstream amplifier, zone controller, or DSP with the combined mix of all inputs.
• Priority Muting — Configurable automatic background music ducking when a priority mic or paging source is active.
• Auxiliary Output — Secondary output for recording, monitoring, or routing to an additional destination.
• Front-Panel Power Control — On/off button accessible from the front panel for installations with staff-accessible equipment.
• Low Distortion — Less than 0.05% THD for clean background music reproduction across the full audio band.
• Wide Frequency Response — 20 Hz to 20 kHz (+0.5 / -1 dB) for accurate audio reproduction.
• Rack-Mount Form Factor — Standard 19-inch rack-mount unit for integration into commercial AV equipment racks.

Typical Applications

• Single-zone retail background music and paging source mixing
• Small restaurant and cafe audio source mixing
• Hotel reception and lobby background music mixing
• Corporate office and reception area audio source management
• Conference room and boardroom audio source mixing
• House of worship lobby and small room audio mixing
• Government facility and institutional single-zone audio

Frequently Asked Questions

Q: Does the CM41 include a built-in power amplifier?

A: No. The CM41 is a standalone mixer with no built-in amplification. It requires a separate power amplifier such as a Lab Gruppen CA or FA series amplifier, or a powered speaker system. For a combined mixer amplifier, consider the CMA1201 or CMA602.

Q: What is the difference between the CM41 and the CM82?

A: The CM82 has 8 inputs and 2 independent mix outputs, suited for two-zone systems with more sources. The CM41 has 4 inputs and 1 mix output, suited for simpler single-zone installations with fewer source devices.

Q: What types of sources can connect to the CM41?

A: The CM41 accepts both balanced mic-level signals (microphones) and balanced/unbalanced line-level signals (media players, streaming devices, CD players) via Euroblock and RCA connectors.

Q: How does the priority muting function work on the CM41?

A: When a signal is detected on the designated priority input (typically a paging microphone), the CM41 automatically reduces the level of all background music inputs, allowing the priority announcement to be clearly heard through the connected speaker system.

Q: What amplifier should be paired with the CM41?

A: The CM41 pairs with any Lab Gruppen CA or FA series power amplifier. For small single-zone systems, the CA601 or CA1201 are common pairings. For larger zones, the CA2401 provides higher single-channel power.

Q: Can the auxiliary output be used for recording or monitoring?

A: Yes. The auxiliary output provides an additional signal send independent of the main mix output, suitable for connecting to a recording device, headphone amplifier, remote monitoring point, or secondary audio zone.
