More about the product
The Hertz H8 DSP is a compact digital signal processor designed to bring precision and flexibility to car audio systems. It is built for those who want to upgrade sound quality without replacing the factory head unit. The processor offers seven signal inputs and eight pre-out analogue outputs, making it easy to integrate with both factory and aftermarket setups.
The design is sleek and practical, allowing installation in tight spaces. It supports high-level and low-level inputs, which means it can work with a wide range of audio sources. The eight pre-out outputs provide full control over amplifiers and speakers, enabling detailed tuning for every channel.
The H8 DSP includes advanced tuning features such as time alignment, equalisation, and crossover management. These tools allow precise adjustment of speaker performance for balanced sound and accurate staging. It also features automatic de-equalisation for factory systems, ensuring a smooth upgrade without losing original functionality.
Control is handled through a PC interface via USB connection. The dedicated software is intuitive and makes configuration straightforward. An auxiliary input is included for additional sources, adding flexibility for different audio needs. While the unit does not include wireless connectivity, its wired setup ensures stable and reliable performance.
Installation is simple thanks to its clear wiring options and compact size. The processor is designed for enthusiasts who value sound quality and customisation. It does not include built-in amplification, so external amplifiers are required. This design choice focuses on delivering clean signal processing rather than power output.
The Hertz H8 DSP is ideal for creating a tailored audio experience in any vehicle. Its combination of seven signal inputs and eight pre-out outputs provides versatility for complex systems. Limitations include the lack of wireless control and the need for a PC during setup, but these are minor compared to the level of tuning precision offered.
