DS18 DSP2.8DBT 2-Channel In and 8-Channel Out Digital Sound Processor with Bluetooth and LCD Screen

DS18 DSP2.8DBT is a 2-channel in / 8-channel out digital sound processor with Bluetooth and an LCD screen, built for car-audio enthusiasts who demand precise, programmable control over their soundstage.

• 2-channel in / 8-channel out: Two input channels feed eight outputs, enabling flexible routing to multiple amplifiers for a multi-amp setup.
• 24‑bit resolution at 48 kHz: High‑precision digital processing with standard automotive sampling for cleaner, more accurate signal restoration.
• Latency 1.08 ms: Low latency processing helps keep timing in the signal path tight, reducing noticeable delay between source and output.
• Frequency range 15 Hz – 22 kHz (-1 dB): Wide, relatively flat operating band to cover sub-bass through treble with minimal attenuation.
• THD+N max 0.01% / SNR 100 dB: Very low distortion and high dynamic range contribute to cleaner, more detailed playback at higher listening levels.
• Bluetooth interface + DSP2.8DBT App (iOS/Android): Direct access to filtration settings via Bluetooth; use the companion app to tune, monitor, and save presets for different songs or genres.
• 3 independent parametric EQ bands per channel: Three customizable frequency bands per output channel give surgical control over tonal balance across the system.
• Dynamic crossover filters: Butterworth, Linkwitz-Riley, and Bessel options let you tailor crossover characteristics to your speakers and enclosure, improving integration and clarity.
• Inputs / Outputs: Unbalanced RCA inputs up to 6 V RMS with 47 kΩ impedance; eight unbalanced RCA outputs up to 2 V RMS with 470 kΩ impedance per channel.
• Power, fuse, and dimensions: 10–15 V DC input, 300 mA; 2 A fuse; dimensions 4.72" × 9.84" × 1.18" (120 × 250 × 30 mm); weight 382 g.

In a real car build, the DSP2.8DBT enables precise routing and tonal shaping across multiple amplifiers, with per-channel EQ and selectable crossover filters to match cabin acoustics and speaker placement. The Bluetooth interface and mobile app simplify tuning and enable quick preset recall for different listening scenarios, while the high‑resolution processing preserves signal integrity from source to outputs.
