RDL DB-NLC1 – Dante Network Volume Control with LEDs, Black

What is the RDL DB-NLC1?

The RDL DB-NLC1 is a PoE-powered network volume remote control in a black Decora-style face that adjusts Dante audio levels from a wall location. A 15-segment LED string shows the attenuation level, and a dedicated Mute button with indicator gives users fast, predictable control. Each unit can run as a Controller or as a Satellite, so up to eight wall stations can share control of the same audio zone.

How does it work?

The DB-NLC1 connects to the network through a single RJ45 jack and is powered by PoE (Class 0, IEEE 802.3af), so no local power supply is needed. Setup is done in a browser session hosted by the unit itself, where the installer assigns the outputs or Dante flows that the control will adjust. When volume is set to a group of outputs at different levels, the dB offsets between them are preserved while the group level changes. Pressing Up and Down together returns audio to a preset level defined in the unit settings, and the Mute condition clears with another press of Mute or either level button. Configured as a Controller, the DB-NLC1 accepts commands from up to seven Satellites and sends single commands to the controlled devices; configured as a Satellite, it can point to another NLC1 or to a network remote such as the RDL D-NMC1. The LED display dims when idle and returns to full brightness on any button press. For public spaces, the unit can lock after 30 seconds of inactivity, and an installer-programmable button sequence re-enables the controls. It mounts in a standard US electrical box with a cover plate sold separately, such as the CP-1B black cover plate, or on a desk or wall with the DC-1B chassis.

What are the key features?

• PoE powered — IEEE 802.3af Class 0 power over the network cable removes the need for a local supply at the wall.
• 15-segment LED level display — Users see the current attenuation level at a glance, and the display dims when not in use.
• Controller or Satellite operation — Up to eight units can work together so a room can be controlled from several entrances.
• Preserved group offsets — Grouped outputs keep their relative dB offsets while the overall level is adjusted.
• Auto-lock option — Buttons can lock after 30 seconds of inactivity with an installer-defined button sequence to re-enable them.
• Browser-based setup — Configuration runs in a browser session hosted by the unit, with no special software required.
