Amplifier Module WiFi FLNA Bluetooth 5.0 2x50W 4 Ohm 24bit 192kHz
The Up2Stream Amp Pro D6 amplifier module, successor to the Amp WB50, is capable of delivering 50W of power under 4Ω on each channel. Its very complete connectivity (wired and wireless) and its many features make this module an ideal choice for your construction / repair / improvement projects of active speakers or integrated amplifiers. The FDA technology of this amplifier also allows it to benefit from a high efficiency (over 90%) in order to have a high power in a compact format and at a contained price.
The card supports AirPlay, DLNA, UPnP, Spotify Connect or QPlay protocols. It directly supports file decoding up to 24bit 192kHz and can read files from a local network, an Internet streaming platform, a physical medium (USB stick) or even via a physical medium connected to a remote connected device (PC, smartphone...).
The amplification stage is articulated around a STA326 chip from ST MicroElectronics. It is therefore an all-digital amplifier (FDA), an approach highly appreciated for its very advantageous power to space ratio.
Since FDA technology does not require conversion, amplification takes place directly from the digital input streams. This allows the module to perform most of the functions of a complete audio system: audio stream reception, stream decoding (if not already I2S), volume control and power amplification with incomparable electrical efficiency.
With this integration, the module is capable of driving loads from 4 to 16Ω It can deliver 2x50W of power under a load of 4Ω with a THD of 1% and on the frequency range 20Hz-20kHz.
The Amp Pro D6 module includes an A31 module from LinkPlay. The latter offers WiFi connectivity specially developed for audio use with DLNA and multiroom compatibility. This WiFi link also allows the amplifier to function as a network player to which audio streams can be streamed from a simple mobile application. High-speed connectivity (802.11 b/g/n with 300Mbps bandwidth) allows audio streams up to 24bit 192kHz to be transferred.
Finally, this feature is not exclusive to a single device since this use can be extended thanks to the multiroom function. It is therefore possible to work several modules together, each connected to its pair of passive speakers, in order to control them collectively or individually from a single connected object.
The module also includes a Bluetooth 5.0 chip, so it is possible to stream audio files simply in Bluetooth from a transmitting device such as a smartphone.
On the connector side, the module has a line input on 3.5mm jack connector and a second on 3 pins PH 2.0mm connector, as well as a USB-A input and an RJ45 connector. For the outputs, there is of course a 4-pin Pheonix type connector for connecting speakers but also a line output on a 2.0mm 3-pin PH connector.

Up2Stream modules have their own 4Stream application (available on Android and iOS). The latter makes it possible to group together most of the control functions (volume, EQ...), playback functions (track selection, play/pause, streaming services...) and even direct streaming functions (direct sending of an audio file from the memory of the phone / tablet).
Many services and protocols are supported, such as AirPlay, DLNA, Spotify Connect, UPnP, Internet radios and stereo pairing (send each channel to a dedicated amplifier module and then synchronize them). There is also an advanced version of this last function with Line-In to All Speakers, which allows each module to share and synchronize its input signal with the entire multiroom network.
finally, the device can natively connect to streaming services such as Spotify, Deezer, Qobuz, Tidal, Napster, TuneIn, iHeartRadio, QQ Music...
