EQ & Sound Processors

Bringing innovation and technology to the Automotive Sound market, the STETSOM STX2848 is a powerhouse Digital Audio Processor designed to enhance and refine your audio system to professional-grade standards. Capable of making extensive adjustments—from precise filtering and graphic/parametric equalization to alignment, phase inversion, and dynamic limiting—this processor gives you full, real-time control over your sound. The Demi-God DG-90.4 utilizes an efficient and robust design, guaranteeing long-lasting durability and superior component stability. With an excellent Channel Separation of >80dB and a remarkably low T.H.D. of <0.01%, this processor ensures a clean, detailed, and dynamic sound image. The wide range of powerful processing tools makes it the perfect foundation for any serious car audio system upgrade   Key Features & Hardware Overview The STX 2848 is designed for both ease of use and professional control, featuring a full suite of management functions: Core Processing Integrated Equalization System: Features a 15-band graphic equalizer with manual tuning or 12 selectable presets for quick sound shaping. Professional Parametric EQ: Dedicated 1 INPUT and 8 OUTPUT Parametric Equalizers for surgical sound corrections and detailed equalization control. Precision Crossover: Define cut frequencies with Butterworth and Linkwitz-Riley filters, offering steep attenuation rates up to 48 dB/8ª. Limiter with Dynamic Attack-Release: Protects your connected amplifiers and loudspeakers by dynamically controlling the attack and release parameters in real time. High Accuracy Delay: Alignment capabilities to correct sound staging issues caused by speaker placement. Convenience & Control LCD Display: Allows visualization and interaction with the processor system in real-time. Hotkeys & Encoder: Shortcut keys for channel selection and a rotary control for intuitive function navigation. Sequencer Function: Allows sequential activation of other products (like amplifiers) via the remote activation (REM) connection. Connectivity: 2 RCA Audio Inputs (A and B) and 8 independent RCA Outputs. Management: Functions for Save/Load Settings (Autosave + 4 slots), Security Password to lock editing, and Language Selection (English, Spanish, Portuguese).
