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 RS201 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 RS201 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 & touch screen multi-touch

The RS201 offers several ways to control the fully configurable playback settings.

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 RS201) allows the user to remotely control all playback parameters.

Finally, the free application ROSE Connect will turn any smartphone running iOS or Android to a remote control for the RS201 via a home network.

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.

Integrated amplifier PurePath

The circuit comprises an integrated amplifier Texas Instrument PurePath 2x50W into 8 ohms.

Is already enough power for up to power standing speakers as well as bookshelf speakers. The RS201 can then add sonorize a moderate-sized listening room.
