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).
