Retrofit DSP chip for Android radios

What is DSP?
In short term: DSP is a digital real-time modification of the audio signal from the radio to improve the sound.

We have compiled more detailed information about DSP here.

What are the benefits of the DSP module?

  • 15 Band Equalizer
  • run time correction
  • high- and low-pass filter
  • more detailed sound settings
  • three storable setups

Suitable for the following models among others:

  • PA series (Android 8.1 and 9.0)*
  • PB series (Android 8.0) [PBx8xxBIP only]*
  • PB/PBX/PQ Series (Android 9.0/10.0)*
  • AVIN Avant 4 (only with PX6)*

This means the type designation of the radio, which can be found on the sticker on the radio, e.g. "PQ7039B" → PQ series

Here you find the installation instructions of the DSP chip

A further improvement of the sound is possible with a modified equalizer app, but this requires root permissions. (e.g. with the firmware of Hal9k)

To ensure that your radio is suitable for retrofitting this DSP chip, open the radio and locate the black slot in the back of the board. Some models already have a "simple" sound chip on the slot, this is simply replaced.
If this slot (or the sound chip that is on it) is not present, then unfortunately this DSP chip does not fit. (see second and third article picture!)

ATTENTION: opening the radio may destroy the warranty seal. We assume no liability or guarantee for your radio.
The installation is at your own risk and should ideally be carried out by a trained specialist.

Note: Colour deviations from the display are possible.

*Information without guarantee. The last article picture shows the location of the type number.

Customer evaluation for "DSP upgrade module for android radios (DSP chip upgrade)"

Man mag ja kaum glauben, dass ein DSP-Chip allein (mit flat EQ) bereits einen deutlichen Unterschied machen kann, aber hier war ich doch sehr positiv überrascht! Ich habe den DSP in ein XTRONS PQ9046BL eingebaut und obwohl natürlich noch ein wenig Optimierung der EQ-Settings nötig war, ist bereits auf Standardeinstellung eine deutlich feinere klangliche Auflösung gegeben. Insbesondere bei höheren Lautstärken ist der Klang mit diesem DSP auch deutlich angenehmer als mit dem Standard-Chip, der vorher in meinem XTRONS verbaut war. Für alle die noch keinen "richtigen" DSP-Chip haben nur zu empfehlen! Einbau war Plug'n'Play, das System hat den Chip erkannt und eine andere/erweiterte EQ-App geladen.
