NAV-TV NTV-KIT1033 ZEN A2B+ GM 2025+ DSP for ACM (GM ONLY), OEM-level seamless integration into factory audio controls

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.

Overview:

• NAV-TV ZEN A2B Plus DSP for ACM — high-performance automotive audio processor designed to deliver a completely flat, unaltered analog preamp output for factory A2B audio systems.
  Engineered around a Burr‑Brown digital-to-analog converter, the unit provides 6-channel analog outputs with a measured signal-to-noise ratio of 113 dB and supports digital audio sampling rates up to 192 kHz/24‑bit.
• The ZEN‑A2B Plus removes factory time delay and equalization so no summing devices, external audio correction DSPs, or removal of factory audio compensation microphones are required.
• Technical specifications: - DAC: Burr‑Brown (high‑performance audiophile grade) - Outputs: 6-channel balanced/unbalanced analog outputs - Signal-to-Noise Ratio (S/N): 113 dB - Supported bit/sample rate: up to 192 kHz (24‑bit)
• Function: DSP preamplifier with flat output, factory time‑delay and EQ bypass - Connections: A2B digital audio interface to factory ACM and multi‑pin harness for 6 analog outputs
• Physical / installation details: - Enclosure: compact matte black module designed for in‑vehicle mounting in OEM integration locations - Mounting: vehicle module/behind‑dash style form factor for discreet installation
• Vehicle compatibility: GM: compatible with General Motors vehicles using A2B/ACM architecture starting with model year 2025 and newer (GM 2025+) Notes: - Intended for integration with factory audio control modules (ACM) and NAV‑TV harnesses for OEM retainment of features while upgrading audio quality.
• Ideal as an audiophile‑grade preamp stage for aftermarket amplifiers while preserving factory audio processing bypass.
