A²B/DSP/AMP Series – The Multitool Of High Resolution Audio
Unlike the vehicles of last century, modern ones feature complex audio systems; often with channels aplenty. These channels are usually monitored by the vehicle's computer system, and many are also heavily processed. Hence when you start planning your audio upgrades you cannot just lob any old device in there. You're going to need components designed specifically for the task. An amplifier with plenty of channels both in and out, and with plenty of processing too. And because there's minimal spare real estate in many a modern vehicle, it'll need to be compact too. However one more challenge, as if you needed one; is that many cars nowadays run the A²B digital interfacing stream. Luckily electronics maestro Goldhorn has already though of all this, as demonstrated by its superb A²B/DSP/AMP range of units.

Design Ideologies
Enjoy unmatched audio precision with Goldhorn’s award winning A²B/DSP/AMP series components. Talk about power and performance combined! The Goldhorn AB218 brings together a twenty-eight channel processor with a twenty channel class AB amplifier, designed for exceptional audio quality. With twenty high-level outputs and sixteen RCA outputs, this unit provides versatility for a variety of configurations. Featuring advanced voltage build-up technology it delivers consistent power, ensuring reliable performance. Ideal for those wanting high-quality audio upgrades without breaking the budget, these units guarantee a transformative listening experience.

Advanced A²B Interfacing
The A²B/DSP/AMP range represents a solution specifically developed for dozens of popular new energy vehicle models, including Tank and BYD. It supports A²B input, extracts the OEM amplifier’s pre-stage signal, adapts to OEM OTA updates and retains active noise cancellation without removing the factory microphones. With outstanding performance, it is the go-to option if you have a car utlising a A²B communication bus.

Integrated Power
The AB218 features a built-in twenty channel powerful amplifier, outputting up to 80 Watts per channel for sixteen channels, and 150 Watts per channel for four channels. In the bridging mode, it can achieve 200 Watts per channel for two channels, stably driving subwoofers and the larger woofers of your and high-end component sets. This can provide a wonderful 360° surround sound effect.

Outputs Aplenty
The A²B/DSP/AMP units’ high and low level outputs can be used independently. This means that no matter your interfacing one can handle a full set of multi-channel Hi-Fi system, getting rid of extra equipment.

ADI Digital Audio Processor
The AB218 is are equipped with a dual-cone ADI high-performance DSP processor chip-set, delivering precise and powerful audio processing capabilities. It enhances processing speed and efficiency, further improving audio detail and accuracy. This provides users with lifelike, clear and rich sound quality.

Active Noise Cancellation
Some car models may experience issues like loud turn signal sounds or cabin noise after audio upgrades, due to incompatibility with the factory active noise cancellation system. Some choose to disconnect the microphone to resolve this, but this can lead to increased engine noise, loss of voice control, Bluetooth functionality and other system malfunctions. The A²B/DSP/AMP designs solve the active noise cancellation, without the need to disconnect the microphone.

Vehicle Specific Plug And Play Solution
The A²B/DSP/AMP units use vehicle specific harnesses to connect directly with the vehicle’s original head unit, simplifying the wiring process. This also leaves the original wiring intact, ensuring no impact on the vehicle warranty occurs.

Easy Installation
These units are designed specifically to fit almost anywhere. It can be mounted under seats, behind panels, in the glove box or even within a storage box. It is so compact that it won’t occupy your car space much at all.

Design Features
The rich heritage of this astute and masterful designer, together with its ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies and latest technological advancements. Let’s canvas of these in more depth.

A²B Communication Extraction
The A²B/DSP/AMP range units directly extract native A²B signals for higher audio fidelity, by interfacing with the A²B bus input and capturing signals directly from the amplifier’s pre-stage. This approach avoids signal loss caused by multiple digital-to-analog conversions during transmission, reducing sound degradation and enhancing audio quality.

Advanced Sound Customisation
All A²B/DSP/AMP series components feature a multi-band digital sound processor, allowing for fine-tuning audio output to match any environment. This capability provides full control over sound settings, letting users optimise their audio experience based on personal preferences or unique installation setups. The detailed control ensures every frequency range can be adjusted for the perfect balance, making these units suitable for both casual listeners and audio enthusiasts.

Top Class Sound Quality
With their class AB amplifiers delivering power aplenty, the A²B/DSP/AMP range ensures consistent, high-quality audio performance. The class AB topology balances efficiency and sound quality, maintaining clarity even at high volume levels. This combination enhances their car audio system without sacrificing reliability or performance.

High Fidelity Streaming
The A²B/DSP/AMP series are equipped with Bluetooth 5.0, providing seamless wireless audio streaming with aptX HD support. The aptX HD codec delivers near-lossless audio quality, making it ideal for streaming high-resolution audio files from compatible devices. This feature ensures users can enjoy a premium listening experience without wired connections, enhancing convenience without compromising sound quality.

Ease Of Connectivity
The A²B/DSP/AMP units’ Bluetooth functionality makes connecting to smartphones, tablets or other Bluetooth-enabled devices simple. Pairing is quick and straightforward, allowing users to start streaming music in seconds. This feature is handy for those who want to enjoy their music library or streaming services on the go without the need for complex wiring.

Flexible Audio System Configurations
The A²B/DSP/AMP series units support advanced audio setups, including a multiple-way active crossover configuration. This capability allows users to set up a dedicated tweeter, midrange and woofer for a richer and more detailed audio experience. These units also ensure optimal sound quality across all frequencies, providing a professional-grade listening experience by enabling separate amplification for each speaker type.

Multiple Output Channels
With a whole swag of low-level and high-level outputs, the A²B/DSP/AMP units offer extensive flexibility for audio system expansion. This range of outputs allows users to connect multiple amplifiers or speakers, catering to both simple and complex audio systems. The variety of output options makes it easy to create a custom audio solution that fits the user’s specific needs.

Signal Summing Capabilities
These units include signal-summing capabilities, which are especially useful when integrated into factory systems with frequency-divided outputs. Signal summing allows these divided signals to be combined, ensuring the entire audio spectrum is available for sound processing. This feature is crucial for getting the most out of OEM systems where speaker outputs are limited in the frequency range. The result is a fuller, more balanced sound optimized across all channels.

Owning The Show
For show cars and competition-grade audio systems, where precision and impact are critical; the A²B/DSP/AMP series units delivers both in droves.
