M6 NFC Bluetooth 5.0 Audio Adapter - Bluetooth Receiver-Transmitter/FM Transmitter

M6 NFC Bluetooth 5.0 Audio Adapter - Bluetooth Receiver-Transmitter/FM Transmitter

The M6 ​​NFC Bluetooth 5.0 Audio Adapter is a 3-in-1 device designed to add wireless connectivity to non-Bluetooth audio devices or to transmit Bluetooth audio signals to wired audio systems.

The device supports three main operating modes:

• RX – Bluetooth Receiver: Transmits Bluetooth audio received from a phone, tablet, or computer to wired speakers, an amplifier, or a car audio system.
• TX – Bluetooth Transmitter: Wirelessly sends audio received from wired sources—such as a TV, computer, or projector—to Bluetooth headphones or speakers.
• FM Transmitter: Broadcasts the audio signal via an adjustable FM frequency in the 87.5–108MHz range.

The M6 ​​utilizes Bluetooth 5.0 + EDR technology. It offers a Bluetooth communication range of approximately 15 meters in open, unobstructed environments. The Bluetooth operating frequency is 2400–2483.5MHz, and the audio frequency response is 10Hz–20kHz. The device features NFC quick pairing; when an NFC-enabled phone is brought close to the M6's NFC zone, the Bluetooth pairing process in RX mode can be completed more quickly. Note that the NFC feature is a pairing function that facilitates easy Bluetooth connection establishment, not an audio transmission technology itself.

The M6 ​​utilizes Bluetooth 5.0 + EDR technology. The device offers a Bluetooth communication range of up to approximately 15 meters in an open, unobstructed environment. It operates at a Bluetooth frequency of 2400–2483.5 MHz and features an audio frequency response of 10 Hz–20 kHz. The device includes an NFC quick-pairing feature; bringing an NFC-enabled phone close to the M6's NFC zone allows for faster Bluetooth pairing in RX mode. Note that NFC is a pairing feature designed to facilitate easy Bluetooth connection establishment, not a direct audio transmission technology. For analog audio connections, the device is equipped with 3.5mm AUX and stereo RCA ports, which can function as either inputs or outputs depending on the operating mode. In TX mode, optical and coaxial digital audio inputs are also available, enabling the transmission of audio from devices like TVs (equipped with optical outputs) to Bluetooth headphones. The M6 ​​can also function as a standalone media player, capable of playing audio files in MP3, WAV, WMA, APE, and FLAC formats from USB flash drives and TF/MicroSD cards. Thanks to its built-in 3.7V 500mAh lithium battery, the device can be used portably without an external power connection, offering an operating time of approximately 8–10 hours depending on usage conditions. Power supply and charging are handled via a DC 5V/500mA Micro USB connection. It also supports hands-free calling in RX mode when connected to a compatible phone, thanks to its built-in microphone. HFP, A2DP, and AVRCP profiles are supported for Bluetooth connectivity.
