Audio/Video 4K player with amplifier / DAC 32bit / 384kHz DSD256
A true high-end Media Center. The RS201E is a Audio / Video player with integrated DAC ES9018K2M, volume control and a 2x50W power amplifier. To offer a complete experience, the device also has a 4K video processor on HDMI output and its own multitouch display.
The unit provides by itself every function one can expect to find in a full stereo system while offering a high level of audio reproduction in an extremely compact housing. Furthermore, its generous input / output pannel backed by large wireless connectivity allow many possibilities of integration: each stage (playback / digital-analog conversion / power amplification) has its own output.
The RS201E will be very useful, should it join an existing audio system or fulfill the function of the whole audio installation by itself.
It is also possible to disable the entire analog part of the device in order to use it as a pure drive.
Great successor to the RS201, this E version now includes FEMTO clocks to make the most of its integrated DAC SABRE.
The analog outputs have been upgraded as well with a significant improvement of speaker terminals.
In addition, the device now supports MQA files and can stream this format directly from the Tidal platform with all the benefits that it can have in terms of file loading time, network load caused by high-resolution data and fluidity in the seamless sequence of tracks.
DAC SABRE ES9018K2M
The digital / analog conversion stage works with a SABRE ES9018K2M chip. This 32bit DAC model supports PCM files up to 384kHz / 32bit with native DSD support up to DSD256 (11.2MHz).
The DAC is integrated following a design intended to make the most of the couple DAC / amplifier chip. The groundings, internal wirings and even the potential vibration of the mechanical parts have been studied to optimize the accuracy of the sound, which considerably refines the channel separation aswell as in lowering the noise and distortion. This results in a very advantageous rate THD of 0.004% measured in speaker output and 0.0018% terminal on the preamp output.
Like all SABRE chips, the integrated DAC in RS201E is equipped with Hyperstream II technology and benefits from its specific algorithms signal reconstruction and an active decorrelation noise / signal.
ESS technology brings Time Domain Jitter Eliminator to RS201E decoding process, which effectively prevents digital noise from being sent to the power amplifier.
Most important, the DAC sabre ESS chips have internal DSP control function which allow a smooth digital volume control. That is to say that the interface offers the comfort of a digital volume control (remote control from multiple media, touch screen / remote / external application).
On the one hand ESS sabre chip is connected to a preamp output for driving directly an external amplifier. On the other hand, it is connected to the internal amplifier (Texas Instrument PurePath 2x50W). This additional output delight will please audiophiles wishing to easily reroute the signal to an auxiliary installation (home cinema system or tubes amplifier for example).
Interface & multi-touch screen
The RS201E has fully configurrable playback settings which offers several ways to control.
The Media Center runs on an Android OS 7.0 (nougat) controlled using a large multi-touch 8.8-inch touchscreen (1920 × 480px) directly accessible on the front pannel. This provides access to all functions while remaining as intuitive to use as our everyday's smartphone or a tablet.
Naturally, when not used for control, the screen is available for displaying video, metadata of your audio tracks (sample rate, title, album art ... etc) or any required settings for playback (volume, forward, repeat, playlists ...).
A bluetooth remote control (provided with the RS201E) allows the user to remotely control all playback parameters as well.
Finally, the free ROSE Connect application will turn any smartphone running iOS or Android to a remote control for the RS201E as long as they share the same network.
The device has a stereo line input (RCA), a Toslink input, two USB inputs (USB 2.0 and USB 3.0) and a micro SD card reader.
Media stream may equally well circulate via home network through an RJ45 port 10/100/1000 BASE-T and high speed WiFi connectivity 802.11 b / g / n / a / ac (2.4GHz / 5GHz).
Bluetooth (V4.0 / V3.0 + HS) is available as well for all cases requiring a one-time connection with a third device.
SSD 2.5" Slot
To go even further and directly integrate real NAS function to the RS201E, the device bottom features a free slot for an SSD 2.5".
It is therefore possible to add a high-speed storage and high capacity to the heart of the device.
The ROSE-201 offers a direct DAC output to bypass the integrated amplifier and out to another system.
Headphones fans will enjoy a high quality headphone output (sharing the decoded signal of the DAC) 3.5mm format, on the front panel
An additional Toslink digital output allows to exploit the integrated NAS function with other decoding devices.
HDMI 2.0 connector provides audio / video with resolutions 480p / 480i / 576p / 576i / 720p / 720i / 1080p / 1080i / 4k (max resolution: 4096 × 2160).
Finally, the amplified signal is sent to the stereo speaker terminals (R- R + / L + L). Meaning, the device is already reday to use once it has been connected to the speakers.
It is possible to supply a secondary devices with an auxiliary power supply output 24 VDC 5A.
Thanks to Android operating system, video support is done with ease. It works exactly on any smartphone or tablet, simply install the video playback application (such as VLC or any other) of your choice from the PlayStore to obtain a full stand-alone 4K video player.
Integrated amplifier PurePath
The circuit uses an integrated amplifier Texas Instrument PurePath delivering up to 2x50W under a 8 ohms load.
This circuit has enough power to drive standing speakers as well as bookshelf speakers. The RS201E is appropriate to sonorize any moderate-sized listening room regardless of the speaker configuration.
Using RS201E as a Stereo System
The RS201E offers numerous way of use and integration to meet very different usage scenarios.
Audiophiles keen to maintain a completely clean environment will appreciate the many dematerialized controls and streaming media to obtain a complete audio system with very little visible cables.
Conversely, audiophiles already equipped with a lot of different devices will especially appreciate the RS201E for its diverse connectivity and its ability to pivot between many devices.
Using RS201E as a Media Center
With its huge capacity for audio / video streaming & decoding, the RS201E is a prime candidate for all applications requiring simultaneous processing of a video stream and High Definition Audio.
The RS201E is a great Media Server since it supports a lot of physical storage devices (SSD, USB, SD card), and can fetch streams from multiple sources on the network.
Using RS201E as an Audio Device
With its optical input, it is quite possible to use the RS201E as any regular digital audio device. This allows all kinds of interesting and atypical connections, especially when it comes to connect a complex TV / home cinema facility that is subject to frequent changes with a pair of static speakers.
The integrated software is equipped with a very well thought CD ripping function to retrieve your digital tracks from a USB CD player.
This function provides digital files in CD quality (FLAC or WAV according to your needs) on a USB pen drive, micro SD card or directly to the memory of an SSD (if such equipment was previously installed).
The R-201E automatically connects to the net to retrieve all the metadata or allows you to input it yourself if no network is available.
The Rose RS201E Roon Ready. This means that it is possible to use Roon and enjoy the many features of this high-resolution playback solution. Roon scans your entire music library and adds information such as pictures, biographies, reviews, lyrics, concert dates, and makes connections between each item to make recommendations. Roon is very complete and offers a myriad of features that will allow you to enjoy your music to the fullest.
