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

This Listing Includes:

• (1) 4-Input / 8-Output Digital Sound Processor

This 4-input / 8-output digital sound processor is built for precise system tuning with flexible routing and clean signal control. It features 4 RCA inputs and 8 fully configurable RCA outputs, letting you run multi-amp and active systems with full adjustability per channel.

At the core is an AKM AK7735 DSP chip running a 96kHz/32-bit sampling rate, giving you high-resolution processing and detailed control over your audio. Each channel includes 31-band parametric EQ, crossover control, time alignment (0 to 20ms), and limiter adjustment, along with adjustable noise gate settings. Output voltage reaches up to 3.3V, with 101dB S/N ratio, 0.04% THD, and strong balanced input noise rejection.

Bluetooth connectivity is included for smartphone control through the app on iOS and Android devices, with 6 saved presets stored locally on the device for quick switching. The aluminum housing comes in a black / silver brushed finish and supports compact installations across many applications. Additional features include remote turn-on input, app voltmeter, LED indicators (Power / BT / Clip / Limiter), anti-corrosion coated PCB, and surface mount component technology.
