<\/p>\nThe MR286 is a Bluetooth 6.0 audio transmitter. It connects to devices such as computers and smartphones via a USB-C interface, wirelessly transmitting audio signals to Bluetooth receivers like speakers and headphones. It supports multiple Bluetooth audio codecs:
\n**LDAC, aptX Adaptive, aptX Lossless, aptX, aptX HD, aptX Low Latency, SBC, and AAC**.<\/p>\n
Bluetooth codec compatibility is determined by both devices \u2014 your receiving device (e.g., Bluetooth headphones) must also support the same high-quality codec for it to be automatically enabled. The device supports **dual connection (1-to-2)** functionality, allowing simultaneous pairing with two receiving devices. *(Note: High-bitrate codecs such as LDAC and aptX Lossless do not support dual connection mode.)*<\/p>\n

**Interface Overview:**<\/strong><\/p>\n **1. LED Indicator Definitions**<\/strong> **2. Functional Operations**<\/strong><\/p>\n – **Power On:**<\/strong> – **Enter Pairing Mode:**<\/strong> – **Auto-Reconnection Mode:**<\/strong> <\/p>\n **Dual Connection (1-to-2) Function**<\/strong> Once both devices are connected, audio will be transmitted to both simultaneously. **Important Notes:**<\/strong><\/p>\n – Bluetooth codec support is mutual \u2014 both the transmitter and receiving device must support the same codec (e.g., LDAC, aptX Lossless) for high-quality audio transmission. The highest available common codec will be used automatically. —<\/p>\n **Product Specifications**<\/strong><\/p>\n – **Brand: AYIN (Ayin) <\/p>\n **Troubleshooting Tips**<\/strong><\/p>\n – **No sound?** Ensure the receiving device is properly paired and selected as the audio output in your system settings. For optimal performance, keep the transmitter clear of metal surfaces and ensure a stable USB-C connection.<\/p>\n","protected":false},"excerpt":{"rendered":" The MR286 is a Bluetooth 6.0 audio transmitter.

<\/p>\n
\nInsert the device into a USB-C port on your computer or smartphone. The device will power on automatically.<\/p>\n
\nDouble-click the function button. The LED will indicate pairing mode (typically flashing).
\nThen, enable pairing mode on your receiving device (headphones, speaker), place it near the transmitter, and wait a few seconds for pairing to complete.<\/p>\n
\nWhen plugged into a USB-C port, the device automatically powers on and searches for previously paired devices to reconnect.
\nIf reconnection fails within 30 seconds, repeat the initial pairing process.<\/p>\n
\nThe MR286 supports connecting to two Bluetooth audio devices simultaneously.
\nTo use this feature:
\n1. Pair the first device as described above.
\n2. After successful pairing, double-click the function button again to re-enter pairing mode.
\n3. Pair the second device.<\/p>\n
\n**Note:**<\/strong> Due to bandwidth limitations, high-bitrate codecs such as **LDAC** and **aptX Lossless** are **not supported** in dual-connection mode. The system will automatically downgrade to a compatible codec (e.g., SBC or AAC) when two devices are connected.<\/p>\n![\"\"](\"https:\/\/www.aoyint.com\/english\/wp-content\/uploads\/sites\/3\/2025\/10\/1.png\")
<\/p>\n
\n– If you encounter connection issues, press and hold the function button for 10 seconds to reset the device to factory settings.
\n– The device draws power via the USB-C port, which will consume your host device\u2019s (phone\/computer) battery.
\n– Before use, lower the system volume to avoid sudden loud audio that may damage hearing.
\n– Slight heating during operation is normal.
\n– Supported audio codecs depend on the receiving device \u2014 different headphones or speakers may support different codecs.
\n– Do not disassemble or attempt to repair the device yourself.
\n– The device is **not waterproof** \u2014 handle with care and avoid exposure to moisture.<\/p>\n
