FDA - 2x40W 8Ω - 24bit / 192kHz - STA326 / CS8422 / AK4452
The E version of FX Audio D802 FDA amplifiers serie now includes WiFi connection (DLNA) to complement Bluetooth connectivity.
This amplifier class D "Full Digital" fulfills by itself the essential functions of a complete audio system such as : source selection, receiving and decoding audio stream, volume control and power amplification.
It offers many possibilities regarding connections and setup with allows it to fit very small places. With a Bluetooth / WiFi input, a OTG-compatible USB port, a Toslink input , a Coaxial input and n additionnal analog RCA input, one can easily plug in simultaneously a computer / digital player, a TV and a CD with the appropriate connectors .
Once the installation is complete, the system works with a remote control (included) or from the front panel interface to select the active source and send the amplified signal to the speakers.
The D802E now includes a Linkplay A3 module. The latter offers WiFi connectivity that has been specially developed for audio use with native DLNA & Multiroom support.
This Wi-Fi connection with DLNA offers features similar to a Network Drive to the D802E, which can receive the audio stream from a simple application running on a smartphone / tablet.
Broadband connectivity (802.11b / g / n with a bandwidth of 300Mbps) authorizes the transfer of dematerialized audio streams up to 192kHz / 24-bit.
Finally, this feature is not exclusive to a single device, since this use may extend to multiroom installation. That is to say, one can install multiple D802E, each connected to its pair of passive speakersand control each of them or alltogether from a single connected device.
In DLNA, performs downsampling at 48kHz.
The control chip / CM6642 conversion can work with resolutions up to 24 bit / 192kHz.
This chip natively supports audio codecs decoding and has interesting specifications as regard to general sound quality (THD + N ≥100dB @ 1kHz ≤0.005%)
To facilitate installation, compatibility, and avoid wasting time on the software configuration, this amplifier requires no driver to operate. The USB input is automatically recognized by all devices. Including smartphones that are OTG ready.
Besides being able to work with other D802E for a massive sound in multiple rooms, the latter is also a headphone amplifier that will provide high quality listening space to a single person .
Headphone amplifier is available thanks to a MAX9722 Stereo Audio DirectDrive chip. With differential inputs, this component is a reference in FX-Audio devices and most of its products use this chip as a headphone amplifier.
The DAC used only for the headphone output is an AKM 4452. A high-performance 32Bit DAC with a signal-to-noise ratio of 115dB.
This output is on a 6.35mm jack port with gold plated connectors for a clean, clear signal.
Few FDA are equipped with a ADC chip (analog to digital) exceeding 44kHz / 16-bit. Typically, the analog input is incidental and merely offers minimum requirements for occasional applications (such as connecting a modest vinyl player or a smartphone does not have the right connections).
Here, the AUX (RCA) analog input is far from an occasionnal solution since PCM1808 ADC chip is capable of sampling the signal to a resolution of 48 kHz / 24-bit. Meaning that the analog input will draw a higher resolution than CD quality from a decent analog signal.
The PCM1808 chip operates with a signal / noise ratio of 99dB and a THD + N of -93dB. If the analog signal processing remains a secondary function like in any full digital amplifier, the D802E offers nevertheless a headphone output that is well above what the market has to offer.
The amplifier can be controlled with your smartphone via a DLNA/UPnP application such as BubbleUPnP, iMediaShare or ArkMC UPnP. You will therefore be able to send files stored on your local network or in your home, or enjoy internet radios and streaming services such as Qobuz, Spotify, or Youtube. In addition, the D802E also allows you to enjoy the multiroom with synchronization of the tracks of each room or independent playback in each room.
It is possible to use the iEast Play application, allowing remote playback control, high resolution file support, multiroom and support for DLNA, Airplay and Qplay protocols. It offers many reading features via an intuitive interface. In addition, this application supports the high definition streaming solution Qobuz. This is a point that will certainly appeal to audiophiles looking for quality files. Of course, the application also supports Spotify, Tidal, Napster, QQMusic, iHeartRadio, Pandora and web radios.
