Phoenix Gold ZDA8.8 amplifier

ZDA8.8 - Premium DSP amplifier with 8 channels and 8 configurable DSP outputs

ZDA8.8 is a high-performance, 8-channel amplifier with 8 digitally configurable DSP outputs, offering 240 W RMS (480 W MAX) power. It has been designed to enhance the sound quality in vehicles, providing purity and warmth of sound thanks to A/B class technology. It is ideal for both stand-alone installations and solutions such as plug-and-play with full OEM integration.

Built-in, intuitive DSP processor allows you to fine tune your sound and tailor it to your individual preferences. Bluetooth 5.0 connectivity enables direct music streaming, allowing the amplifier to act as an independent sound source (head unit) or bypass the factory system, offering a better quality without loss of OEM functionality.

Better sound quality than factory amplifiers

ZDA8.8 redefines car sound quality in its price range - far outweighs standard factory amplifiers. Unlike the typical Class D technology used in other products, the ZDA8.8 uses a class A/Bwhich offers warmer and more natural sound. Even without DSP tuning the sound is impressive, and with DSP you can tune the system to your own musical tastes.

OIS - Impedance simulation OEM

Function OEM Impedance Simulation (OIS) ensures full compatibility with modern central units and amplifiers. By simulating loudspeaker impedance, it retains the functionality of OEM systems and eliminates problems that can occur during plug-and-play installations.

---

Input Priority

Function Input Priority ensures seamless integration with the vehicle's factory head unit. You can use low-level or digital inputs (Bluetooth, optical, coaxial) without losing system sounds such as:

• parking sensors,

• warnings,

• OEM radio.

Example: if the factory head unit uses a high-pass filter to limit bass, it can be bypassed by sending music via Bluetooth to the DSPwhile retaining full OEM functionality.
