The Zen AVB-GM is the most important element in any compatible-vehicle sound-system upgrade.

The Zen AVB-GM provides pure, clean stereo audio - it eliminates all OEM crossover filters, fixed and dynamic EQ, phase manipulation, compression, etc. It is both a high-quality digital-to-analog converter and an audiophile analog preamp - the OEM analog signal path is eliminated. in home audio terms, it is a standalone D/A converter and audiophile preamp, connected to the OEM infotainment system via a proprietary digital network connection. For more information on networked preamps, see this Knowledgebase article. 

Any Automatic Noise Cancelling systems are automatically disabled (if present), as is any "fake exhaust" note added to the sound output signal. 

The Zen AVB-GM  has both high-quality analog RCA outputs and digital SPDIF outputs.

How many channels does the Zen AVB-GM have? 

This network preamp has six analog RCA outputs, and one stereo TOSLINK SPDIF output. The SPDIF output requires a third-party device with a compatible SPDIF input and D/A conversion. 

What makes this preamp sound so good?

Some of that is the Zen Audio network preamp technology (more on that here), and some of it is the audiophile-grade D/A converters and op-amps used in the signal path. T

Does it work in all GM? 

It works in specific GM vehicles that use the automotive Ethernet infotainment network technology. Please see the Vehicle Compatibility tab for specific coverage information.

Does it work in my Escalade? 

Sorry, no, the Escalade is a unique platform. 

See the installation manual for more information.
