The Atoll ST200 Signature network player has a sleek design and a larger five-inch TFT display that displays album covers, song titles, tags, file resolution and other information. The output stages of the Atoll ST200 Signature, assembled on discrete elements, do not use feedback and operate in pure A-class, and the Burr-Brown PCM1792 chip handles the digital-to-analog conversion. A separate power transformer is used to power the output audio section, and high-quality components are installed in the circuits, including MKP capacitors. The digital section is also powered by a separate transformer.
Atoll ST200 Signature supports DLNA, UPnP protocols and can connect to a local network wired (via RJ45 LAN connector) or via Wi-Fi connection. This opens access to playback of audio files stored on servers and computers on the local network, including PCM up to 24 bit/192 kHz and DSD64/DSD128. The streamer supports the gapless function (playing without pauses) and allows you to create playlists. Playback control is available using the real time streaming protocol RTSP (real time streaming protocol). The kit includes a remote control, but it is much more convenient to “command” the network player using a proprietary application for devices based on Android or iOS. This application also provides direct access to online music services such as Qobuz, Tidal and Deezer. Airable web service is supported, guaranteeing access to more than 100,000 radio stations.
The model also has a built-in Bluetooth receiver for wireless audio playback, which is broadcast from Bluetooth sources. The all-metal body of the Atoll ST200 Signature is equipped with a thick front aluminum panel, which, among other controls, contains buttons for an analog volume control that uses switched resistors. The regulator can be “bypassed” by activating the by-pass mode, which is important when connecting a network player to a preamplifier or full amplifier.
The facade has a built-in USB port for external drives and a 3.5 mm headphone jack. On the rear panel there is a full set of S/PDIF inputs, another USB for flash drives and HDD, a LAN port and two digital outputs (optical and coaxial). Analog switching is represented by a pair of linear RCA inputs and one RCA output. Thanks to this set of connectors, the streamer can be used as a full-fledged preamplifier. The device is equipped with a trigger output that allows you to activate a connected amplifier or DAC with a corresponding trigger input.
