Description
ARC Audio LR2 Programmable DSP Controller
The ARC Audio LR2 is a programmable single-function digital remote controller designed for seamless integration with ARC Audio stand-alone DSPs and DSP amplifiers. As part of the ARC Audio DNA DSP ecosystem, the LR2 provides direct, intuitive control over one user-defined function—allowing precise, on-the-fly system adjustments without accessing software.
Ideal for OEM upgrades and fully custom DSP-based systems, the LR2 delivers predictable and synchronized system control through ARC Audio’s DNA 2.7+ PC software platform.
Programmable Single-Function Control
- Assignable to one dedicated control function per installation
- Common applications include master volume, subwoofer level, bass boost, and more
- Digital controller design for precise and repeatable adjustment
- Fully programmable through ARC Audio DNA 2.7+ software
Dual DSP Control Capability
The LR2 can control up to two ARC Audio DSPs simultaneously, making it an excellent solution for advanced multi-processor systems that require synchronized adjustments across components.
- Controls one DSP with included cable
- Controls two DSPs with the addition of a second LR2-compatible cable (sold separately)
- Maintains identical behavior across both processors
Installation & Included Hardware
- Includes 5-meter (20-foot) 4-pin low-impedance data cable
