Description:
HUIDu HD-A4 LED sending box is a professional dual-mode LED display player designed for use with LED screens. It has two operating modes: synchronous and asynchronous. In synchronous mode, it can be used to display real-time video or other content, while in asynchronous mode, it can be configured to display preset content at specific times. The support for multiple media types and remote control capabilities make it an ideal choice for businesses, organizations, and individuals who want to create engaging and dynamic digital signage.
The HD-A4 is powered by the Android platform with a quad-core 1.6GHz processor, giving it unparalleled video processing performance. It can handle a variety of LED display types, including full-color, single-color, and dual-color displays. Whether you are looking for a synchronous LED controller or an asynchronous LED media player for a high-performance LED display, the HD-A4 has everything you need.
Supports Asynchronous and Synchronous Playback
HD-A4 dual-mode LED display player is a reliable and flexible device that provides users with the convenience of both asynchronous and synchronous playback modes, depending on their needs. With its dual-mode capability, users can switch between the two modes depending on their requirements.
In asynchronous mode, the HD-A4 LED player can store and play pre-loaded content without the need for a constant internet connection. In addition, asynchronous mode allows for scheduling content playback, which can save time and effort for users who need to regularly update their displays.
On the other hand, synchronous mode allows for real-time content playback, which can be useful in situations where content needs to be updated frequently or dynamically, such as live events or news broadcasts. The HD-A4 LED player can receive real-time content from various sources, such as cameras, computers or other media devices, and display it on the LED screen with high-quality quality.
Support HDMI video input
In terms of video capabilities, the HD-A4 uses a higher-level HDMI interface to improve interference immunity and bandwidth transmission speed to ensure simultaneous transmission of high-definition video signals. In addition, HDMI allows the HD-A4 to support simultaneous input of video and audio signals without the need for additional audio equipment, providing great convenience and flexibility for the user.
Comes with Wi-Fi module, supports mobile app control
The HD-A4 LED display controller is an innovative device that comes with a set of advanced features to facilitate efficient control of LED displays. One of the most notable features is the built-in Wi-Fi module, which allows for easy control via a mobile app.
With the Wi-Fi module, the HD-A4 LED controller can easily connect to a wireless network, allowing users to control their LED screens using their mobile devices. Users can use the mobile app to:
- Brightness adjustment.
- parameter configuration.
- firmware update.
- adding a schedule.
- and others.
Through application management, HD-A4 not only provides greater flexibility and convenience to users, but also ensures that they can effectively monitor and manage their LED displays.
8GB Built-in Memory, Support U-disk Expansion
In addition, users can easily display pre-loaded content without the need for an internet connection or a computer, as the HD-A4 comes with 8GB of built-in memory. The ultra-large storage capacity allows the HD-A4 to provide ample space for storing and displaying a variety of content, as well as supporting offline playback.
In addition, the HD-A4 supports U-disk expansion, further expanding the storage capacity and flexibility of the device. With this feature, the HD-A4 offers a powerful storage option that facilitates the processing of high-definition content and video, creating dynamic and engaging visual displays for any application.
Support for remote cluster control via 4G internet
To further enhance the accessibility, flexibility and convenience when it comes to managing LED displays, HD-A4 offers a 4G module function that supports remote cluster control via the internet. With this function, users can access and control their displays from anywhere with a 4G signal, meaning they no longer need to be physically present at the display location to make changes or updates.
Automatic Device Recognition Function via Controller ID
Manually setting the IP address for the LED controller box can be a time-consuming and error-prone task, especially when managing multiple controllers. Even a small error in setting the IP address can cause problems and require significant troubleshooting efforts. In addition, manual setting can lead to inconsistencies between different displays, leading to confusion and additional errors.
However, the HUIDU HD-A4 dual-mode LED controller box solves these problems by offering an automatic device recognition function. It eliminates the need for manual setup, providing a quick and easy setup process that minimizes the risk of errors. The HD-A4 controller box can be automatically recognized by the controller ID, which simplifies the setup process and ensures accuracy and consistency across multiple displays.
Equipped with a standard 3.5mm audio output
The HD-A4 is also equipped with a standard 3.5mm audio output, providing users with an easy way to add sound to their LED displays.
One of the main advantages is that the interface provides synchronized audio output, ensuring that the sound is precisely synchronized with the video content displayed on the LED display. As a result, the HD-A4 can help attract the attention of passersby and enhance the impact of the display.
In addition to enhancing the visual effect, the audio interface also allows for easy integration with other audio systems. Users can connect the HD-A4 to a range of audio systems, including speakers and amplifiers, and more, providing a flexible and versatile audio output solution.
Support HDMI HD video zoom, no need video processor
Video zoom is a very useful feature for LED displays, but it requires a LED video processor to achieve it. To make things simple, the HUIDU HD-A4 LED controller box has an integrated HDMI HD video zoom function, allowing users to achieve this effect without an additional LED video processor. Users don’t need to spend extra time and money configuring or purchasing other equipment to set up the system.
