The ZDSP8 is designed for sound quality enthusiasts who demand precision, flexibility, and seamless OEM integration. Built around a premium Burr Brown DAC and delivering 5V RCA outputs, it provides exceptional signal clarity and dynamic range – making it the perfect foundation for high-performance audio systems with precise tuning and maximum control.

With 8 channels of processing, advanced tuning capabilities, and multiple input options, the ZDSP8 gives you full control over your system – whether you’re upgrading a factory setup or building a fully active system.

Bluetooth V5.0 Built-in

The ZDSP8 has Bluetooth V5.0 built in with an external antenna, providing extended range and a stable connection – ideal for both in-car listening and playing your system from outside the vehicle.

OIS - OEM Impedance Simulation

The ZDSP8 is equipped with OEM Impedance Simulation (OIS), ensuring compatibility with modern head units and amplifiers. By simulating speaker impedance, it maintains the functionality of your vehicle's OEM head unit and prevents potential issues in OEM installations.

Input Priority

The Input Priority feature ensures effortless integration with your vehicle’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. For instance, if your vehicle has a high-pass filter that limits bass output, you can bypass this limitation by streaming audio directly to the DSP via Bluetooth while maintaining full OEM functionality.

Preset Switch Trigger

The Preset Trigger lets you instantly switch between two sound profiles using a 12V signal.
It toggles between the active preset and preset 6 – ideal for setups where listening conditions change. For example, in a motorhome, you can have one preset tuned for driving and another for when parked.
With a simple 12V trigger connection, the DSP automatically switches presets – no manual adjustment needed.

Software

Take full control of your sound system with free PC software (compatible with Windows 10 and 11) and mobile app. Connect via the included USB-B cable or Bluetooth to unlock a suite of powerful tuning tools:
