ZDAP-BMW4 Information

When using ZDAP-BMW4, the center speaker output will no longer be active. However, this setup delivers 2x 70W to the underseat woofers, enhancing bass performance and overall sound dynamics.

If you prefer to keep center speaker amplification with reduced power to the underseat woofers, choose ZDAP-BMW3 instead.

ZDA6.8 – DSP Amplifier

The ZDA6.8 DSP amplifier takes in-car audio performance to a whole new level, surpassing all standard factory amplifiers. Unlike common Class D amplifiers, the ZDA6.8 employs Class A/B technology, producing warmer and more natural sound.

• Enhanced Sound Quality – Even without DSP tuning, the improvement is substantial.
• Advanced DSP Features – Customize your audio experience to your personal preference.

Technology & Features

OIS – OEM Impedance Simulation

The ZDA6.8 is equipped with OEM Impedance Simulation (OIS), ensuring full compatibility with modern head units and amplifiers. By simulating speaker impedance, it maintains the functionality of the OEM head unit, preventing potential plug-and-play issues.

Input Priority

This feature ensures seamless integration with your BMW’s OEM head unit. You can use low-level inputs or digital sources such as Bluetooth, Optical, or Coaxial – without losing vital system sounds like parking sensors, alerts, and radio signals.

If your BMW’s system has a high-pass filter that limits bass output, you can bypass it by streaming audio directly to the DSP via Bluetooth, while maintaining full OEM functionality.

DSP Outputs

The ZDA6.8 DSP amplifier not only upgrades your system but also allows for future expansion:

• Two DSP-configurable RCA outputs (Channels 7-8)
• Connect additional amplifiers, such as a subwoofer amplifier
• Full optimization via DSP software
• Delay settings, filters, and equalization options for the best performance

Advanced DSP Software

Gain full control over your sound system with the free, user-friendly PC software (compatible with Windows 10 & 11). Connect via the included USB-B cable and access advanced tuning features:

• 31-Band Parametric EQ (PEQ) – Fine-tune frequencies for optimal balance
• Filter Customization – Choose from Bessel, Butterworth, and Linkwitz-Riley filters with adjustable slopes from -6dB to -48dB
• Time Alignment – Built-in delay calculator for a perfect soundstage
• Custom Channel Routing – Full control over how audio is distributed
• Advanced Linking Options – Copy or relate channels for quick optimization
