Phoenix Gold ZDA4.8 - ZD Series 8 Channel Car DSP with 4 Channel Built-In Amplifier

6IN - 8OUT | 31BAND EQ | 8CHANNEL DSP WITH BUILT-IN 4CHANNEL HIGH PERFORMANCE CLASS A/B AMPLIFIER (70W RMS)

OIS – OEM Impedance Simulation

The ZDA4.8 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, preventing potential issues with plug-and-play 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.
