DS18 DSP4.8BTM Digital Sound Processor

DS18 DSP4.8BTM — 4 In / 8 Out DSP with Bluetooth App Control

Take full control of your sound system and transform raw power into clean, professional audio.

The DS18 DSP4.8BTM gives you complete tuning authority over your entire setup—allowing you to shape your soundstage, fix imbalances, and extract maximum performance from every speaker.

Why This Matters

Most systems are loud… but not clean.

• Vocals aren’t centered

• Bass overpowers everything

• Highs are harsh or inconsistent

• Left/right staging feels off

This isn’t a speaker problem—it’s a tuning problem.

A DSP fixes that.

Total System Control

• 4-channel input → 8-channel output

• Independently tune every speaker in your system

• Perfect for multi-amp setups, active builds, and pro audio systems

This is where your system goes from “installed” → “dialed in”

Precision Tuning (Real Control, Not Guesswork)

Each output channel includes:

• 8-band parametric EQ (not basic EQ — real tuning)

• Time alignment (fix staging and imaging)

• Independent gain control per channel

You’re not just adjusting sound—you’re engineering it.

Advanced Crossovers

Choose your filter type:

• Butterworth

• Linkwitz-Riley

• Bessel

Dial in exact crossover points for:

• Subwoofers

• Mid-bass

• Vocals

• Tweeters

This is how you eliminate overlap, distortion, and muddy sound.

Bluetooth App Control (No Laptop Needed)

Control everything from your phone:

• EQ adjustments

• Save presets (daily / demo / show mode)

No guessing. No reconnecting wires. Real-time tuning.
