4-Input / 8-Output Digital Sound Processor with Bluetooth and App Control

4-In / 8-Out Digital Sound Processor with Bluetooth App Control (96kHz / 32-Bit DSP)

Take full control of your car audio system with this 4-input / 8-output digital sound processor, designed for precise system tuning, flexible routing, and clean signal management. With 4 RCA inputs and 8 fully configurable RCA outputs, it allows you to run multi-amplifier or fully active audio systems with complete channel adjustability and mixing control.

At the core is the AKM AK7735 DSP chip operating at 96kHz / 32-bit sampling, delivering high-resolution processing and accurate sound reproduction. Each channel includes 31-band parametric EQ, crossover configuration (HPF / LPF / Band-Pass), phase control, time alignment from 0–20ms, and limiter adjustments, along with adjustable noise gate settings for precise system optimization.

Bluetooth 5.1 connectivity allows full control through a mobile app for iOS and Android, making it easy to tune your system directly from your smartphone. The processor stores up to 6 presets locally, enabling quick switching between different tuning profiles.

Designed for durability and signal clarity, the processor features Tiffany RCA connectors, anti-corrosion PCB coating, and a compact aluminum housing, making it ideal for a wide range of car audio installations.
