DS18 DSP8.8BT 8-Channel In and 8-Channel Out Digital Sound Processor with Bluetooth

The DS18 DSP8.8BT is an eight-channel in, eight-channel out digital signal processor with Bluetooth, built for serious car-audio builds that demand precise, per-channel tuning.

With a 31-band graphic EQ, per-channel crossovers, and a dedicated DS18 app, it puts high-resolution sound shaping in a compact, road-ready package.

• 8-Channel In / 8-Channel Out: Enables processing across eight inputs and routing to eight outputs for multi-amp, multi-speaker configurations.
• 31-Band Graphic Equalizer: Provides broad tonal shaping from 20 Hz to 20 kHz, letting you target peaks and dips to achieve your preferred sound signature.
• Bluetooth Interface + DS18 App: Direct access to filtration settings via Bluetooth; App available on the App Store and Google Play for tuning and preset management.
• Per-Channel Adjustable Crossover: HPF/LPF crossover points from 20 Hz to 20 kHz with selectable slopes of 6/12/18/24/36/48 dB/Oct, dictating how frequencies are sent to speakers, amplifiers, and subwoofers.
• High-Resolution DAC/ADC: 24-bit DAC and 24-bit ADC with dynamic ranges of 108 dB (DAC) and 105 dB (ADC); THD+N < -98 dB, preserving detail and clarity.
• Processing Power: 147 MIPS DSP speed, 32-bit processing, and 72-bit accumulators for stable, artifact-free EQ and filtering.
• Inputs / Outputs: RCA (Female) I/O; supports high- and low-level inputs; input impedance 20 kΩ; input sensitivity 0.2–9 V.
• Maximum Pre-Out: Up to 8 V RMS with 200 Ω pre-out impedance for strong, consistent signal to amplification stages.
• Power & Protection: Working voltage 9–16 VDC; remote input 9–16 V; remote output 12.8 V (0.5 A); fuse size 2 A.
• EQ & Presets: 31-band parametric EQ with selectable Q; supports EQ presets and user presets for quick recalls.
• Physical Specs: 6.37 in × 3.6 in × 1.24 in; weight 1 lb.

In a real install, the DS18 DSP8.8BT excels in multi-amp setups, providing precise tone control, crossover management, and recallable presets to adapt to different music and vehicle acoustics. The Bluetooth app enables convenient tuning and monitoring, while the high-resolution DAC/ADC and wide frequency response deliver detailed, faithful playback from 20 Hz to 20 kHz. Its flexible I/O, strong pre-out level, and per-channel processing make it a capable centerpiece for a refined, custom car audio system.
