STEG SS-DSP12 II
In the pursuit of modern automotive acoustic perfection, signal processing and amplification are the true backbone of an extraordinary listening experience. The STEG SS-DSP12 II stands at the pinnacle of car audio technology, merging audiophile-grade components, immense multi-channel power, and precise digital tuning into a single high-performance chassis.
Hi-End Premium Audio Architecture
At the core of the STEG SS-DSP12 II is a uncompromising, audiophile-first component selection. Anchored by an ADI high-performance DSP chip, the unit integrates the AKM5538 ADC and AKM4458 DAC, capable of handling digital signals up to 768kHz/32-bit. Paired with professional-grade operational amplifiers and audiophile capacitors, the SS-DSP12 II reproduces sound with exceptional clarity, ultra-low distortion, and natural warmth.
Versatile High-Resolution Inputs
Designed to seamlessly adapt to OEM systems and modern high-res digital sources, the SS-DSP12 II provides a comprehensive suite of connectivity:
Analog Inputs: 12 high-level inputs and 2 AUX inputs.
Digital Inputs: Fiber optic and coaxial inputs supporting high-resolution audio up to 192kHz/32-bit.
Wireless & OTG: Bluetooth 5.0 streaming with aptX HD, AAC, and SBC codec support, alongside high-speed OTG digital input.
Powerful 12-Channel Class-D Amplification
Delivering serious power without sacrificing space or thermal efficiency, the integrated Class-D amplifier generates a robust output of 8 channels x 80W + 4 channels x 100W at 4Ω (14.4V, 1kHz, 1% THD). For further system expansion or running dedicated external power amplifiers, the unit also features 12 low-level RCA outputs.
Advanced DSP Tuning & Equalization
The SS-DSP12 II offers comprehensive control over every nuance of your acoustic environment:
Input Channel EQ: Independent 10-segment parametric/graphic equalization for exact source compensation.
Dynamic Loudness Control (DLC): Automatically optimizes tonal balance across varying volume levels.
Custom Crossovers: Fully adjustable Butterworth, Linkwitz-Riley, and Bessel filters with variable slopes up to 48dB/Octave for seamless speaker integration.
Precision Spatial Audio & Time Alignment
Transform your vehicle's interior into a true live concert stage. The SS-DSP12 II allows installers and tuners to fine-tune each of the 12 output channels independently:
Gain Control: Precise volume adjustments ranging from -40dB to 0dB.
Phase Switching: 0° / 180° phase inversion for seamless acoustic blending.
Microsecond Time Delay: Ultra-accurate delay adjustment (0–20ms) to center the soundstage precisely at the listener's ear, establishing deep spatial immersion and sharp imaging.
Summary
Whether upgrading a modern factory sound system or crafting a competition-grade active multi-way setup, the STEG SS-DSP12 II delivers the raw power, dynamic precision, and acoustic fidelity required by the most demanding car audio enthusiasts.
