Description
ARC Audio PS6.8 8-Channel Digital Signal Processor
The ARC Audio PS6.8 delivers advanced DSP functionality in a compact, value-focused platform. Built around the Analog Devices ADAU1452 DSP core, the PS6.8 provides flexible signal routing, comprehensive tuning capability, and broad OEM integration support for aftermarket audio systems.
Overview
Flexible DSP Processing for OEM and Aftermarket Systems
The PS6.8 is a stand-alone digital signal processor designed to bring advanced tuning and integration capabilities to a wide range of vehicle audio systems. With 6 analog inputs and 8 output channels, it provides the flexibility needed for accurate signal routing and system optimization.
Built on the Analog Devices ADAU1452 DSP platform, the processor supports ARC Audio's DNA tuning software, giving installers and enthusiasts access to the same tuning environment used throughout the ARC DSP lineup.
Key Features
Designed for Modern Integration
- 6 differential analog inputs supporting RCA or speaker-level signals.
- 8 RCA outputs with output voltage up to 3.5V.
- Toslink optical and digital coaxial inputs.
- Support for digital audio signals up to 96kHz.
- DC and signal-sensing automatic turn-on capability.
- USB-C connectivity for tuning and expansion.
Signal Integration
OEM-Friendly Input Compatibility
The PS6.8 is engineered for integration into factory and aftermarket systems. Differential analog inputs accept signal levels from 2V to 16V RMS, allowing compatibility with a wide range of OEM source units and amplified audio systems.
DSP Architecture
24-Bit Signal Processing Platform
The PS6.8 utilizes a fixed-point native 24-bit DSP architecture based on the Analog Devices ADAU1452 processor. Signal conversion is handled by an AKM 5358B ADC and Cirrus Logic CS-4344 DAC platform.
- Analog Devices ADAU1452 DSP processor.
- AKM 5358B analog-to-digital conversion.
- Cirrus Logic CS-4344 digital-to-analog conversion.
- 8 total DSP output channels.
Control & Presets
User Preset Management
The PS6.8 supports up to four user-defined presets. Presets can be accessed through compatible optional control solutions, allowing system configurations to be switched without connecting a PC.
- Up to 4 user-defined presets.
- Optional LR-2 controller compatibility.
- Preset selection via optional manual trigger switches.
- Compatible with ARC Audio DNA tuning software.
System Expansion
Multi-Processor Capability
For advanced installations, multiple compatible processors can be linked through a continuously connected USB hub, allowing a single PC and GUI interface to control multiple DSP units simultaneously.
Multi-processor operation requires each processor to maintain a full-time USB connection through a non-amplified USB hub.

Used Frequently Asked Questions
- What does used mean? Used products may be unused customer returns that are essentially "new" items, or they may be previously installed products that were returned under warranty or during our return policy period.
- What is the warranty? All of our used items come with a 90-day warranty.
- What's it look like? All of our used items are inspected and graded by our returns team at our facilities. They will test them and grade them to one of four standard gradings: Used Open Box, Used Very Good, Used Good, and Used Acceptable. Please see the following descriptions of each grade - also note that if an item falls under ANY of the criteria for a certain grade, even though the rest of the product is better, we will give it the lowest grade.
- Used Open Box An item in perfect working condition. Original protective wrapping may be missing, but the original packaging is intact and in good condition with minor damage possible. Instructions are included.
