Grimm Audio LS1r Controller

The Grimm Audio LS1r is the physical control center for the LS1 loudspeaker system. One large dial handles volume, source selection, and mute. Two additional digital audio inputs on the unit itself let you connect sources directly at the listening position. When placed at a distance from the speakers, the included IR remote provides wireless control over all functions.

Key Features of the Grimm Audio LS1r

• Single-Dial Control: Volume, source selection, and mute through one beautifully machined rotary encoder. No menus, no screens, no complexity.
• Two Extra Digital Inputs: Connect additional AES/EBU sources directly at the controller, keeping cables short and routing simple.
• IR Remote Compatible: Place the LS1r at the listening position and control it wirelessly with the optional Grimm IR remote.
• System Setup Access: Connect a Mac, PC, or Linux computer via USB to access all LS1 system parameters through the LS1 remote software.
• USB Audio Playback: The USB connection doubles as a high-quality digital audio interface for computer playback into the LS1 system.

Part of the LS1 System

The LS1r connects to the LS1c, LS1v2, and LS1a loudspeakers, providing the tactile control interface that completes a Grimm system. Pair with the MU1 or MU2 for streaming, add the SB1 or LS1s for deep bass, and the LS1r ties it all together from wherever you sit.
