Reliable systems. No distractions. Here’s to conversations that matter, and the clarity to make them unforgettable.

Crossover Applications in Audio Systems: Principles, Functions, and Optimization Strategies A crossover is fundamentally a filter designed to selectively pass or attenuate signals based on their frequency. Crossovers are primarily categorized into low-pass filters and high-pass filters, which correspond to the functions of low-cut and high-cut filters, respectively. A low-pass filter allows low-frequency signals to pass through while attenuating or blocking high-frequency signals above a specified cutoff frequency. Often referred to as a high-cut filter or treble-cut filter, it is commonly used to remove high-frequency noise or unwanted high-frequency content from an audio signal. Common types of low-pass filters include the Butterworth filter. A high-pass filter , conversely, permits high-frequency signals to pass while attenuating or blocking low-frequency signals below a specified cutoff frequency. Also known as a low-cut filter, it is frequently employed to eliminate low-frequency noise. For instance, in a conference sound reinforcement system, a high-pass filter can be applied to a microphone signal to cut low-frequency noise around 80Hz, thereby enhancing speech clarity. In practice, the application of crossovers depends on the performance characteristics of different frequency bands within a signal. When the low-frequency content negatively impacts the overall audio quality, a high-pass filter can be engaged to attenuate these frequencies. Conversely, when the high-frequency content is problematic, a low-pass filter can be used to reduce it. In cases where a specific frequency band performs poorly while others are satisfactory, low-pass and high-pass filters can be combined to create band-pass or band-stop filters. This allows for targeted attenuation of the problematic frequency band while preserving the integrity of other frequency bands, thus optimizing the overall audio performance. The flexible application of crossovers significantly enhances an audio system’s sound reproduction, bringing it closer to its ideal state.

Audio Console: The Central Hub for Audio-Video Control In the world of audio and video production, the audio console—often referred to as a mixing console or mixer—is an indispensable tool. Yet for many outside the professional audio field, it may still seem somewhat mysterious. Let’s pull back the curtain and explore what an audio console is and what it does. At its core, an audio console is designed to blend, route, enhance, and manage multiple audio signals before sending them to various outputs or systems. Think of it as the command center for sound—directing and fine-tuning how each element comes together. Inputs to a console can come from a wide range of sources: microphones, instruments, media players, computers, and more. Each source connects to an individual channel, where settings like volume, tone, EQ, and compression can be independently adjusted. Volume adjustment is one of the most fundamental tasks. Using faders or knobs, engineers balance the level of each channel to ensure a cohesive mix—where no sound overpowers another unnecessarily. Equalization (EQ) allows for shaping the frequency response of a signal. By boosting or cutting specific bands, you can make vocals clearer, instruments warmer, or overall sound more natural. Compression helps manage the dynamic range of audio, preventing sudden peaks and keeping volume consistent, which is essential for both live and recorded sound. Pan control is another powerful feature. It positions a sound within the stereo field (left or right), creating a sense of space and depth in the final mix. For more complex setups, grouping channels is a major advantage. Multiple channels—such as all drum mics or backing vocals—can be assigned to a single group for unified control, saving time and ensuring consistency. Additionally, most consoles support built-in or external effects processing, like reverb, delay, and chorus, to add texture and atmosphere to the sound. Different applications call for different types of consoles: Recording consoles prioritize pristine sound quality and detailed processing. Live sound mixers emphasize quick adjustments, reliability, and ease of use. Broadcast consoles are built to meet industry standards and support continuous operation. In short, the audio console remains the central nervous system of audio-video production. Whether you’re a seasoned engineer or exploring audio for the first time, understanding its role is key to creating professional and engaging listening experiences.

NearLink Technology | Rewiring the Future of Global Wireless Audio with 5G-Inspired Tech In an era dominated by Bluetooth and Wi-Fi for wireless audio, Chinese native Nearlink technology is redefining a “Chinese standard” for audio transmission. Leveraging core technologies derived from 5G and scenario-specific innovations, it has emerged as a pivotal engine, propelling Chinese audio industry from merely following global trends to setting the pace. As the global first unified short-range communication protocol encompassing “data, audio, video, control, positioning, and sensing,” it not only shatters the bottlenecks of conventional technologies but also marks a strategic leap for Chinese technological sovereignty. Chinese Audio Game-Changer Nearlink was born from Chinese drive for technological self-sufficiency. In 2019, Huawei partnered with over 300 companies to form the Nearlink Alliance . After three years of intensive R&D, the Nearlink 1.0 standard was launched in 2022, pioneering the introduction of 5G Polar code technology into short-range communication. This breakthrough enhanced anti-interference capability by 7dB and reduced packet loss in complex environments to a mere 0.01% . With the upgrade to Nearlink 2.0 in 2024, new features like high-precision positioning and lossless audio transmission were added, achieving a transmission rate of 12Mbps. Low latency down to 20ms , and support for over 100 concurrent devices , comprehensively outperforming Bluetooth and Wi-Fi. Comparison of Nearlink, Bluetooth 5.3, and Wi-Fi 7 Comparison of RISC-V, ARM, and x86 Architectures Core Advantages The Lossless Audio Revolution: Nearlink supports 24-bit/48kHz lossless audio transmission , doubling the sample rate of standard Bluetooth and enhancing audio detail reproduction by 30% . Already implemented in products like the Huawei FreeBuds Pro 3 , it enables 1.5Mbps super CD-quality sound . The “Invisible Shield” Against Interference: Combining dynamic frequency hopping and Polar code protection, Nearlink boosts connection stability by 50% in interference-heavy environments like schools and airports, effectively eliminating common issues like dropouts and static noise in traditional microphones. A Fully Independent Supply Chain The rise of Nearlink signifies Chinese achievement of a fully self-reliant ecosystem in audio, “from chips to protocols”: Domestic Ecosystem: From HiSilicon chips to a 100% proprietary protocol , Nearlink has established a complete domestic industrial chain. By 2024, the Alliance surpassed 1,000 members , spanning consumer electronics, education, and professional audio, with over 154 certified products and annual shipments reaching 70 million units . Global Standardization: The Nearlink Alliance has gained recognition as an international industrial and standards organization . Collaborations with global brands like Sony and Panasonic are paving the way for its adoption worldwide. By 2025, Nearlink solutions for digital car keys and industrial wireless control are set for deployment in Europe and Southeast Asia. Transitioning from “domestic alternative” to “global standard,” Nearlink is not just a symbol of Chinese tech independence but a “Chinese engine” for the global audio revolution. It is redefining the boundaries of wireless connectivity, infusing the audio industry with “Chinese power,” and allowing the world to hear Chinese vision of a lossless future . The S-Track LARK 100 is the market’s first wireless audio product based on the Nearlink (NearLink SLE 1.0) protocol, representing the perfect application of Nearlink technology in wireless microphone devices. Designed for voice amplification in scenarios like education and training, the LARK 100 integrates ultra-low latency, intelligent sound field calibration, anti-interference transmission, and multi-functional audio processing . Users can enjoy a high-clarity, low-latency, stable, and reliable sound amplification experience with simple, lightweight wearability. In the future, its application will expand to more scenarios, further driving the popularization and development of Nearlink technology.
