Utilizing the same processing power as NAV-TV’s competition proven M650-GM, the ZEN-A2B produces a completely flat audio output without any factory time delay or equalization, eliminating the need for summing devices, an audio correction DSP or the removal of the factory audio compensation microphones. Volume, Fade[2], Balance and Bass/Treble tone controls are retained through the factory radio and echo cancellation for the factory Bluetooth hands-free system is supported.

Traditional audio integration devices convert a high level output from the factory radio or amplifier to low level, or manipulate a fixed preamp level audio signal. However, this method relies on the factory radio or amplifier to perform the digital to analog conversion (D/A) and may lead to less than ideal sound quality.  Unlike traditional devices, the ZEN-A2B extracts the audio directly from the A2B digital audio stream and performs the D/A conversion internally. Utilizing a 128 bit floating point DSP and 384 kHz 32 bit DAC, the ZEN-A2B produces a 12 channel analog output with an extremely low noise floor and a S/N Ratio of 114dB.

For use with 3rd party digital sound processors[2], the ZEN-A2B includes a variable TOSlink digital output which may be used simultaneously with the analog outputs, or by itself. The variable digital output allows for the system volume to be controlled via the factory radio and steering wheel controls without the need to access any 3rd party controller.

For ease of use, the ZEN-A2B  is configurable through dip switch settings.  User selectable features of the ZEN-A2B are:
