QUESTYLE QCC DONGLE PRO 2 Bluetooth 6.1 Transmitter
The Questyle QCC Dongle Pro2 is a compact Bluetooth audio transmitter designed to send sound from an iPhone, iPad, Mac, computer or other USB source to a compatible wireless headphone or speaker. Compared to the QCC Dongle Pro, this update extends protocol support with LDAC, aptX, aptX HD, aptX Adaptive, aptX Lossless, LHDC, LE Audio and Auracast, in order to cover a wider range of devices and use cases.
Questyle QCC Dongle Pro2: Bluetooth 6.1
The integration of Bluetooth 6.1 aims to maintain a stable connection while improving synchronization and latency management depending on the paired equipment. Compatibility with LDAC up to 990 kbps, as well as with Qualcomm aptX codecs, allows more data to be transmitted than with standard Bluetooth codecs, provided a headphone or speaker supporting the selected codec is used.
Questyle QCC Dongle Pro2: LE Audio and Auracast compatibility
LE Audio support allows the QCC Dongle Pro2 to communicate with future devices based on this low-power Bluetooth architecture. The dongle also integrates Auracast, a "one-to-many" audio broadcasting feature that allows a single source to be transmitted to several compatible receivers. This feature nonetheless depends on Auracast support in the headphones, earphones, speakers or hearing devices used.
Questyle QCC Dongle Pro2: Apple MFi certification
Apple MFi certification governs the integration of the QCC Dongle Pro2 with Apple devices and facilitates its use as an external Bluetooth transmitter. In particular, it makes it possible to bypass the native codec support limitations of certain iPhones and iPads, in order to transmit the signal in LDAC, aptX or LHDC to a compatible receiving device. Operation remains subject to the respective compatibilities of the dongle, the source and the receiver.
Questyle QCC Dongle Pro2: Questyle app
The dedicated Questyle app centralizes the management of the dongle and its connections. It lets you check the operating status, manage paired devices, select the codec used and perform firmware updates. This interface also makes accessible the settings that usually remain dependent on the automatic negotiation between the source and the Bluetooth receiver.
Questyle QCC Dongle Pro2: Snapdragon Sound certification
The QCC Dongle Pro2 is Qualcomm Snapdragon Sound certified, with support for the aptX, aptX HD, aptX Adaptive and aptX Lossless codecs. This compatibility allows the transmission to be adapted to different objectives, audio bitrate, latency or stability, when the receiving headphone or speaker also belongs to the compatible ecosystem. The dongle thus fits equally well with music listening, video playback or gaming, depending on the capabilities of the paired devices.
