The ARC Audio X2800.8 DSP is an 8-channel Class-D amplifier with an integrated 12-channel DSP, engineered for modern OEM integration and active system design. Built around an Analog Devices ADAU1462 32-bit processor and AKM Velvet Sound ADC/DAC architecture, it delivers low-noise signal conversion, precise tuning control, and flexible routing in a compact chassis. Eight bridgeable amplifier channels provide 50 W x 8 at 4 Ω or 85 W x 8 at 2 Ω, with the option to bridge for up to 170 W x 4 at 4 Ω. A 10 Hz–22 kHz frequency response and up to 8 V of RCA pre-out voltage give installers the bandwidth and headroom needed for high-performance speakers and external amplifiers. The onboard DSP offers 12 channels of processing, 4 assignable RCA outputs, and a full toolset for crossovers, EQ, delay, phase, summing, and mixer routing, all managed through ARC Audio’s DNA software. The X2800.8 DSP accepts up to eight balanced analog inputs (RCA or speaker-level) with 0.5–32 V sensitivity, plus a digital coaxial input supporting sample rates up to 96 kHz. Auto-sense turn-on, adjustable turn-on/turn-off timing, and a remote turn-on output simplify integration with factory and aftermarket electronics. iDatalink Maestro AR compatibility allows direct communication with select OEM source units while retaining factory features and enabling channel reassignment inside the DSP. A compact footprint, triple 30 A fuse bank, and fan-assisted cooling make the X2800.8 DSP suitable for under-seat, side-panel, or OEM-location installations where space and airflow are limited. With 8 channels of power, 12 channels of DSP control, and robust OEM integration options, it is designed for real-world multi-channel and active front-stage systems where tuning accuracy and reliability matter more than marketing hype.

• Key Feature: 8-CHANNEL CLASS-D AMPLIFIER WITH 12-CHANNEL DSP – Integrated DSP amplifier with 8 bridgeable Class-D channels and 12 total DSP channels for active front stages, multi-way systems, or complex OEM replacement builds.
• Key Feature: POWER OUTPUT FOR MODERN SYSTEMS – Delivers 50 W x 8 @ 4 Ω, 85 W x 8 @ 2 Ω, or 170 W x 4 bridged @ 4 Ω (not recommended at 2 Ω bridged), protected by three 30 A fuses and designed to operate from 8.0–17.1 V systems.
• Key Feature: HIGH-RESOLUTION PROCESSING & CONVERSION – Uses an Analog Devices ADAU1462 32-bit fixed-point processor with AKM Velvet Sound 5558B ADC and AK4438 DAC, 10 Hz–22 kHz frequency response, S/N up to 98.5 dB (4 V analog) and –119.3 dB (digital), plus coaxial S/PDIF input up to 96 kHz / 32-bit.
• Key Feature: FLEXIBLE INPUTS, OUTPUTS & TUNING – Eight balanced analog inputs (RCA or speaker-level) with 0.5–32 V sensitivity, 10 kΩ input impedance, four RCA outputs up to 8 V, and full control of EQ, crossovers, delay, phase, summing, and routing via ARC Audio DNA software with up to four user presets.
• Key Feature: OEM INTEGRATION & CONTROL OPTIONS – Supports auto-sense turn-on (signal and DC BTL on Ch 1/2), adjustable amp and remote turn-on timing, iDatalink Maestro AR amplifier-replacement capability (with appropriate vehicle module and harness), USB-C connection, and optional LR-2 external controller or manual trigger switches for preset selection.
