Utilizing the same processing power and audiophile grade componentry as NAV-TV's other competition proven ZEN products, the ZEN-A2B Plus 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. 

The ZEN-A2B Plus uses a burr-brown DAC with 6 channel analog output with a S/N Ratio of 113dB and a bit rate of up to 192khz. A true audiophile pre-amp.

The ZEN-A2B Plus amplifier replacment interface seamlessly converts 2018-2024 Ford & 2025+ GM factory A²B® (Automotive Audio Bus) to 6-channel analog RCA and TOSLink output. This pre-amp covers both manufactures with the flick of a dipswitch. 

When used in Ford B&O applications, the Zen can now DSP and control the outputs of the factory ACM. This allows for higher channel count systems at a lower cost and a much simplier install. B&O Ford systems are Bi-amplified, this means that the back B&O amplifier does not control all the channels, for example on the 8 speaker B&O system the front tweeters are powered by the ACM (front headunit) the rest is off the B&O amp. These channels can now be fully controlled by the Zen.

When installed in regular B&O systems the Zen will allow 2 ACM channels to be DSP'd (front left and right tweeter)

When installed in an Unleashed B&O system, the Zen will allow 4 ACM channels to be DSP'd (front left and right tweeter and rear doors(2021-2023) or overhead speakers(2024)
