NAV-TV Corp announced the industry’s first car audio preamplifier designed for use with a popular new audio/video communications system used in General Motors and other vehicles, known as AVB.
NAV-TV’s new ZEN-AVB-GM is the fifth product in its car audio preamplifier series.
The ZEN-AVB-GM produces a completely flat audio signal without any factory time delay or equalization, so installers may add aftermarket amplifiers and speakers, while retaining the factory radio. No other summing devices, or DSP or compensation microphones are required, said NAV-TV.
The preamplifier is compatible with 2017 to 2020 Cadillac, Chevrolet and other GM vehicles equipped with AVB infotainment radios IOT (8” with navigation) or IOS (8” without navigation) and Bose. This covers about 80 percent of the current GM trucks and vehicles with an 8-inch screen or Bose system, said NAV-TV.
The device allows the factory radio and steering wheel controls to continue to control Volume, Fade and Balance.
NAV-TV uses a 128 bit per channel floating point DSP and 192 kHz 32 bit TI (Burr-Brown) DAC. The ZEN-AVB-GM produces a 6 channel analog output (Front L/R, Rear L/R, Sub and Center) with a peak voltage of 6.3V and a S/N Ratio of 112dB.
All warning chimes and audible turn signal indications are attenuated to factory levels and, along with Onstar, Navigation prompts and Bluetooth, are passed to the front output channels, eliminating the need for an external speaker. The unit provides a 500mA output for controlling aftermarket devices and, additionally, retains the factory 3 band equalizer.
The device also has 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.
The ZEN-AVB-GM is configurable through dip switch settings. User selectable features of the ZEN-AVB-GM are:
- Factory Bass control becomes a Subwoofer Level Controller or controls bass for the entire system (Analog output only) – eliminates the need for a sub control knob.
- Loudness control for extended bass response at low levels or loudness off (Analog output only)
- Selectable output level: 0dB or -6dB. Digital Output at 24 bit 48 kHz.
In order to make the Zen Audio compatibility process simple for General Motors vehicles, NAV-TV has produced a short video that will help qualify the vehicle infotainment system to ensure compatibility using a QR code reader. The video may be viewed at https://youtu.be/YMHfpRytPho.
Pre-orders of the ZEN-AVB-GM (sku# NTV-KIT955) are being accepted starting October 29. The product will begin shipping on November 4 with a retail price of $599.
