1. Digital Input

WaveFlex Caraudio offers the possibility to add a digital input to your DSP A8 (factory fitted). Take advantage from the digital output of your head unit and increase the overall performance of your installation.
Caution: To have the possibility to alter the master volume on the outputs of the DSP A8, we highly recommend our Remote control MRC (sold separately).

Modifications included:

- Digital input board

- New face plate

- Setup and configuration of additional hardware

For our customers already owning a DSP A8 with analog inputs wishing to upgrade to digital input, please contact us via the contact form before sending in your unit, the upgrade has to be done in our factory. We do offer a 6 months warranty extension for units still under warranty.

2. 8 analog inputs

WaveFlex Caraudio also offers the possibility to buy the DSP A8 with eight analog inputs for those wishing to connect either several sources and/or a head unit with multiple analog outputs (e.g. Front / Rear / Sub).
This version is only available new from factory; an upgrade from a 2 channels version to 8 channels is not possible. Please contact us via the contact form for purchasing this unit, it’s only available on special order.
