The Eton Stealth 7.1 DSP Amplifier represents the pinnacle of automotive audio engineering, combining Advanced Class-D amplification with cutting-edge Digital Signal Processing in one compact unit. This German-engineered powerhouse delivers exceptional sound quality with ultra-low THD+N distortion of just 0.003% at 5W RMS, ensuring every musical detail reaches your ears with crystal clarity.
Asymmetric Power Distribution for Maximum Flexibility
The Stealth 7.1 DSP features an innovative asymmetric power design with five channels delivering 100W RMS at 4 ohms and two high-power channels providing 180W RMS at 2 ohms. This configuration makes it ideal for complex audio systems requiring both precise mid-range control and powerful bass reproduction. The unique 7.1 channel layout is designed explicitly for three-way front systems with center channel capability, or two-way front and rear configurations with subwoofer integration.
Wireless Hi-Res Audio Streaming Technology
Stream high-resolution audio directly from your smartphone, tablet, or laptop via the integrated WiFi connection, avoiding unnecessary analog-to-digital conversion that can compromise sound quality. The amplifier supports both iOS and Android devices, offering seamless AirPlay integration for iPhone users and direct WiFi streaming for Android devices.
Professional-Grade DSP Processing
The integrated 8-channel DSP offers extensive sound customization, featuring 10 fully parametric EQ bands per output (80 bands in total) and 21 fully parametric EQ bands per input (168 bands in total). This level of control enables precise acoustic tuning, runtime correction up to 20ms in 0.02ms increments, and comprehensive filter management with high-pass, low-pass, and band-pass options ranging from 6-to 48dB slopes.
The revolutionary ETON DSP Control app transforms your smartphone into a professional audio tuning center. Access every parameter wirelessly, from basic volume adjustments to complex filter configurations. The intuitive interface allows real-time changes while listening, making system optimization effortless. Create and save multiple presets for different listening preferences or vehicle occupants.
Professional Acoustic Measurement Tools
The integrated RTA (Real-Time Analyzer) system includes a dedicated microphone input that connects directly to the amplifier. This professional-grade measurement capability allows for precise acoustic analysis of your vehicle's interior, enabling data-driven tuning decisions. The built-in measurement system eliminates guesswork, helping achieve optimal frequency response and imaging.
Hi-Res WiFi Streaming Without Compromise
Stream lossless audio directly from any source on your smartphone using AirPlay or direct WiFi connection. This bypasses the limitations of Bluetooth compression, delivering true high-resolution audio quality. The system supports all major streaming services and local music files, making it the perfect solution for audiophiles who demand uncompromised sound quality.
Flexible Input and Output Management
The amplifier's six high-level and six low-level inputs provide maximum flexibility for integration with any source unit. Freely assignable inputs and outputs with built-in mixer functionality allow creative signal routing. The DSP-controlled subwoofer output ensures perfect integration with your low-frequency system, while the remote output facilitates easy system expansion.
Smart Power Management
Start/stop capability ensures reliable operation in modern vehicles with automatic engine shutoff systems. The amplifier is specifically designed for low voltage operation, preventing startup noise and ensuring clean power-up sequences. Auto-sense technology detects input signals automatically, providing seamless integration with factory audio systems.
Customizable Aesthetics
Both the amplifier and remote control feature freely selectable RGB LED illumination, allowing perfect integration with your vehicle's interior lighting scheme. The sleek, compact design ensures the amplifier can be mounted virtually anywhere while maintaining the sophisticated appearance expected in high-end installations.
What makes the Eton Stealth 7.1 DSP different from other car amplifiers?
The Stealth 7.1 DSP combines a powerful 7-channel Class-D amplifier with professional-grade 8-channel DSP processing in one compact unit. Its asymmetric power distribution, ultra-low distortion, and comprehensive app-based control set it apart from conventional amplifiers. The built-in WiFi streaming and Real-Time Analyzer make it a complete audio processing solution rather than just an amplifier.
Can I use this amplifier with my factory radio system?
Yes, the Stealth 7.1 DSP is designed for seamless integration with factory audio systems. It features both high-level and low-level inputs with selectable impedance, auto-sense technology for automatic turn-on, and extensive signal processing to overcome the limitations of factory systems. The DSP can correct for factory EQ curves and provide the full-range signal needed for aftermarket speakers.
How does the WiFi streaming feature work with different smartphones?
iPhone users can stream via AirPlay by selecting the ETON device from their music app's output menu, while Android users connect directly through WiFi settings. Both methods provide lossless audio transmission, bypassing Bluetooth compression limitations. The amplifier creates its own WiFi network that your device connects to for streaming.
What type of speaker system is this amplifier best suited for?
The 7.1 configuration is optimized for three-way front systems with center channel and subwoofer, or two-way front and rear setups with center channel and subwoofer. The asymmetric power design with two high-power channels makes it ideal for driving larger midbass drivers or dedicated subwoofers while maintaining precise control over tweeters and midrange drivers.
Is the mobile app user-friendly for beginners?
While some users note that the ETON app interface isn't as polished as competitors like Helix, it provides comprehensive control over all DSP functions directly from your smartphone. The app includes guided setup procedures, preset management, and real-time tuning capabilities. Beginners can start with basic adjustments and progressively explore advanced features as their expertise grows.
What are the power requirements and installation considerations?
The amplifier requires a 12V automotive electrical system and draws a significant amount of current under load. Proper power and ground connections are essential, with recommended wire gauges determined by the total system power. The compact 250 x 142 x 50mm dimensions allow installation in tight spaces, but adequate ventilation is necessary for optimal thermal performance.
Can I expand the system with additional amplifiers?
Yes, the remote output and flexible signal routing capabilities allow easy system expansion. You can use the Stealth 7.1 DSP as a signal processor feeding additional amplifiers, or integrate it into larger multi-amplifier systems. The DSP's mixer functionality enables creative signal distribution across multiple amplification stages.
