Product Highlights:
1. The device is equipped with reserved DC interface, audio input AUX interface, and headphone output port, and is compatible with XH2.54 interface, providing rich product interfaces for users to freely choose according to their needs, making it more convenient to use.
2. Onboard antenna, capable of transmitting up to 50 meters in open environments without the need for an external antenna. If installed inside a metal casing, to avoid signal shielding, you can purchase an external antenna and reserve an IPEX1 antenna base for installation.
3. TYPE-C interface can be used for power supply/USB sound card. For the QCC5125 model, official software can also be connected through the USB interface to operate the EQ in the internal DSP, which is particularly suitable for experienced enthusiasts with software foundation.
4. The device is equipped with an I2S output interface, which can be connected to amplifiers with I2S input function. At the same time, a button expansion interface is reserved to achieve functions such as switching up and down songs, volume adjustment/playback, pause, etc., with strong expandability.
5. The equipment comes with an acrylic shell and a fixed magnetic column, which can be installed with magnetic adsorption for easy and fast operation.
6. Design a "Cancel BT Connection Button". When an unknown BT device maliciously connects, long press the button for 3 seconds to cancel the connection of the unknown BT device.
7. QCC5125+PCM5102A chipset achieves lossless transmission and decoding, perfectly displaying various dynamics and details of sound. High frequency is delicate without burrs, mid-range is rounded, and low frequency is powerful and elastic. Its outstanding parameter performance includes: dynamic range of 112dB, signal-to-noise ratio of 112dB, and distortion of -93dB. Showcasing unparalleled sound quality performance. Such excellent performance makes you deeply feel the improvement in sound quality.
8. High quality fever capacitors are used in key areas, which perform well in parameters such as dissipation factor, leakage current, ripple current, and ESR, significantly improving the speed, dynamics, texture, and density of sound, and particularly enhancing the overall quality of high, medium, and low frequencies. The capacitance has excellent dissipation factor, which can effectively reduce the impact of temperature, voltage, and frequency on sound quality. Capacitors with low leakage current not only reduce aging rate and prolong service life, but also significantly reduce noise. Low ESR capacitance can reduce high-frequency impedance, improve dynamic response speed, and enhance sound performance.
matters needing attention:
1. Power supply requirements: This device does not support AC power supply. Please be sure to use DC voltage with a power supply range of DC: 8-24V, or use a 5V Type-C interface for power supply.
2-input switching: AUX and BT inputs are automatically switched through signal relays, with BT connection taking priority and sound card second. When BT is not connected to the sound card, it automatically switches to AUX mode.
The BT device name is XinYi. Simply search and click to connect.
