DS18’s i48DSP gives you total command over your sound system!

With 4 RCA inputs and 8 fully configurable RCA outputs, this DSP (digital sound processor) lets you build and fine-tune your audio experience across any setup.

Bluetooth App Control: Set crossover points, time alignment, limiter, and EQ right from your phone. Integrated with Bluetooth Version 5.1, the i48DSP lets you make live tuning adjustments wirelessly using DS18’s iDSP app (iOS and Android).

High-Performance Audio Tuning: Equipped with a 96kHz/32-bit sampling rate DSP chip (AK7735) and CS4344 signal conversion, the i48DSP gives you pinpoint audio control. It features a 31-band parametric EQ on each channel, routing with mixing, bandpass filtering, limiter per output, and a built-in noise gate: all with impressively low distortion (0.04% THD).

Clean Signal, Low Noise: With an output of up to 3.3V and a 101dB signal-to-noise ratio, the i48DSP ensures ultra-clean sound with minimal interference. It also includes clip and limiter LEDs to prevent distortion and protect your equipment during high-output sessions.

Built to Fit Anywhere: This compact DSP is housed in a brushed aluminum body with surface-mount technology and anti-corrosion PCB coating. Designed to work with all systems, the i48DSP installs easily into a variety of vehicles and integrates seamlessly with aftermarket or OEM systems.
