1x ARC Audio PS16-Pro 16-Channel Pro-Series Stand-Alone DSP w/ Maestro "AR" Compatibility (PS16-Pro)
ARC Audio PS16-Pro 16-Channel Digital Signal Processor
The ARC Audio PS16-Pro is the flagship processor in the Pro-Series DSP lineup, designed for the most demanding multi-channel audio systems. Built around the powerful Analog Devices ADAU1462 processor, the PS16-Pro delivers 16 channels of output control for advanced system architectures and complex OEM integrations.
High-resolution audio processing is handled by dual AKM Velvet Sound ADCs paired with an AK4438 DAC, enabling clean signal conversion and processing up to 192kHz at 32-bit resolution. With flexible input options including differential analog inputs, optical Toslink, and optional digital coax connectivity, the PS16-Pro integrates easily into factory or aftermarket audio systems while delivering precise control across every speaker channel.
When paired with ARC Audio’s DNA Tuning Software, installers gain extensive system control including advanced routing, crossover configuration, equalization, and time alignment adjustments. The result is a processor built for ultimate system flexibility and precise sound tuning in complex installations.

1x ARC Audio LR2 Programmable DSP Level Controller (LR-2)
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
- Pre-mounted to right-angle L-bracket for quick installation
- Knob and circuit board removable from bracket for custom mounting applications
