64-Bit Sigma350 DSP
Powered by a cutting-edge Sigma350 DSP chip, the DSP.3S handles over 1.2 billion operations per second, delivering ultra-precise, high-resolution audio with a bandwidth beyond 40 kHz.
ACO – 32 Bit Co-Processor
An integrated 32-bit ACO CoProcessor ensures ultra-fast control, lightning-quick switching between up to 10 sound presets, and reliable system communication. It supports future software upgrades, enhancing system adaptability.
96 kHz Native Signal Processing
Unlike most processors capped at 48 kHz, the DSP.3S doubles the sampling rate to 96 kHz, allowing playback of full-bandwidth high-res audio with unmatched detail and clarity.
RealCenter
Creates a focused and stable soundstage by dynamically generating a unique center signal from the stereo image, enhancing the experience for both driver and passenger.
Augmented Bass Processing
Combines Dynamic Bass Enhancement and SubXpander to boost low-end performance. Delivers deeper, cleaner bass without distortion—even at high volumes.
StageXpander
Dramatically widens the stereo soundstage without compromising localization, making music feel more immersive in constrained in-car environments.
ClarityXpander
Enhances treble brilliance with added harmonics for more transparent highs, with adjustable intensity and optional dynamic control for the center channel.
Smart High-Level Input with ADEP.3
Advanced diagnostics protection enables seamless connection to factory head units without triggering errors or losing functions like fader control.
Dual Digital Inputs
Now includes both optical (up to 96 kHz) and coaxial (up to 192 kHz) SPDIF inputs, offering flexibility for connecting high-resolution digital sources.
Smart Control Port (SCP)
Future-proof SCP allows multifunctional accessory connections and provides power directly, supporting clean and compact installations.
HEC Slot Expansion
Add-on support for modules like Bluetooth® HD audio, high-res USB audio streaming, or other system expansions through a dedicated HEC slot.
DSP PC-Tool V4
Powerful yet intuitive tuning software enables precise, detailed configuration of the audio system, including EQ, time alignment, crossovers, and custom routing.
Input Signal Analyzer (ISA)
Visualizes and corrects pre-EQ’d signals from OEM radios, ensuring optimal integration and signal neutrality before processing.
Flexible Routing & Memory
Independent routing matrices for analog, digital, and auxiliary inputs with 10 storable sound setups make it versatile for multiple configurations.
Power Save Mode
Automatically powers down connected amplifiers after 60 seconds of signal inactivity, reducing battery drain in modern vehicles with extended standby radio states.
Start-Stop Ready
Maintains stable operation even if vehicle voltage drops as low as 6 volts during engine cranking.
Auto Digital Signal Detection
Seamlessly switches between analog and digital inputs based on signal presence. Manual override available via optional remote control or PC software.
