The Lab.Gruppen LAB.LEVEL4 is a professional-grade, four-channel tabletop volume controller designed for commercial sound installation applications, particularly those utilizing the Commercial Install Series amplifiers or the LUCIA amplifier platform. Its primary function is to provide intuitive, zone-level volume and source control in environments such as restaurants, retail spaces, hotels, and conference facilities. The device offers a tactile and user-friendly interface for managing audio levels across multiple zones or areas without requiring access to the main system processor or amplifier rack.

Featuring a clean, durable aluminum faceplate, the controller is built for daily use in public settings. Each of its four independent channels is equipped with a smooth, long-throw rotary encoder for precise volume adjustment and a discrete push-button for muting the corresponding zone. Channel status is clearly indicated via integrated LED rings around each knob, providing immediate visual feedback on mute status and output level. The unit requires no software configuration for basic operation, making it simple to install and use.

Power and audio communication are delivered through a single Ethernet cable connection, utilizing the common Control Network (C.N.) protocol. This streamlined connectivity simplifies installation by reducing cable clutter. The LAB.LEVEL4 is designed to integrate seamlessly into a networked Lab.Gruppen ecosystem, allowing installers to create a distributed control system where local, user-accessible volume adjustments can be made while the core system parameters remain protected from unauthorized changes.
