Know before you buy
The Audison C20 acts as a bridge between various audio sources and your Audison processor. It converts analog and coaxial digital signals into a clean TOSLINK optical output, allowing you to integrate smartphones and portable high-resolution players into your car audio system.
Yes, it supports high-resolution audio up to 24-bit/192kHz when using the digital coaxial input. When using the analog input, the signal is converted to 24-bit/48kHz for processing.
The C20 includes a built-in isolation transformer specifically designed to reduce electromagnetic interference (EMI). This helps ensure your audio signal remains clean and free from the common noise often found in vehicle electrical environments.
The C20 features automatic input switching with AUX-IN priority. This means it will seamlessly switch to your analog device when a signal is detected, and you can adjust the input switch delay to suit your preferences.
Not at all. Its compact dimensions of 69 x 26 x 54.5 mm make it easy to tuck away in tight spaces, such as behind a dashboard or under a seat, helping to keep your installation clean and organized.
The unit features a 3.5mm stereo jack that supports both 3-pole and 4-pole connectors. It also includes an adjustable gain pre-amplifier, allowing you to fine-tune the input level for optimal signal coupling with your specific source device.
