HIFI ROSE RS520-ADVANCED ALL-IN-ONE NETWORK STREAMER
HIFI ROSE RS520 is an all-in-one product with built in network player, DAC and amplifier.
For DAC and amplifier module, it is equipped with ES9038PRO DAC, the flagship DAC chip of ESS technology and class AB amplifier module developed by applying new material GaN FET are mounted.
RS520 is an advanced all-in-one network streamer that consolidates the main functions of existing all-in-one streamers into one based on ROSE´s unique design know-how and functions accumulated over many years.

UNCHANGEABLE VALUE
The design of the HIFI ROSE RS520 focused on values that did not change over time.
A refined design that will not change over time and a bold ventilation hole for heat dissipation represent a gentleman with both functionality and enterprising appearance.

INTEGRAL ALUMINIUM HOUSING
The housing of RS520, which is made with generous use of high-durability 6000 class aluminum material, is manufactured by an all-in-one process in which four sides are produced as one part.
The all-in-one manufacturing process is the most ideal method to fundamentally block vibrations that may occur between separated parts, significantly reducing noise waves that can affect sound quality.

12.6 INCH WIDE LCD TOUCHSCREEN
Visible audio is emphasized using Hi-Fi ROSE’s spacious, wide-viewing-angle multi-touch LCD screen. With a size of 309*82.9 (mm) and a 1920*515 resolution LCD panel, you can enjoy a smooth and clear screen.

ES9038PRO DAC
It is equipped with ES9038PRO, the flagship DAC chip of ESS technology, a world-class DAC manufacturer.
ES9038PRO has extremely low total harmonic distortion plus noise (THD+N) of -122 ㏈, and dynamic range (DNR) of 140 ㏈, making it the industry's best DAC chip. The maximum sampling frequency and bit rate are PCM 768 ㎑, 32 bit, and DSD512 is supported.

ES9038PRO significantly reduces software implementation time compared to previous products to reduce system cost, and minimizes gain error between devices by automatically adjusting gain.
In addition, it is equipped with ESS technology's exclusive jitter canceller to provide exceptional audio clarity. Seven low-delay filters allow you to play music that meets the needs of a wide range of users.

GAN BASED CLASS AD AMPLIFIER
In order to achieve the perfect class-D amplifier design, switching operation speed and accuracy must be ensured. However, due to the limitations of silicon FET, the linearity is weak compared to class-A or class-AB, which limits the ability to produce natural sounds.
The class-AD amplifier mounted on RS520 uses a new material GaN (gallium nitride) FET to dramatically reduce the “dead time” by 1/3 to maximize linearity.
Please enjoy the powerful output of 250 W per channel with Hi-Fi ROSE's class-AD amplifier that maximizes operating speed and accuracy to achieve the perfect class-D amplifier structure.

EQUALIZER
RS520 supports the equalizer function (Hereafter EQ) that can emphasize (boost) or attenuate a specific frequency band of a voice signal.
The RS520 EQ is a parametic equalizer that can set the frequency band for for amplification and attenuation arbitrarily, and can adjust the bandwidth of the Q-factor for each frequEncy. Five frequency bands can be set, and each can be adjusted up to +-10db.

CONNECT ANYTHING
You can enjoy seamless streaming through the network. It supports Airplay and DLNA functions.
Also you can connect the device to a smartphone, computer/Giga Ethernet/Bluetooth connections.

ROSE CONNECT APPLICATIONS
It include a dedicated remote control application that allows users to conveniently control and smartly manage ROSE devices.
The remote control application works on various platforms including iPhone, Android phone and PC.

INNOVATIVE ROSE OS SYSTEM
HiFi ROSE´s own OS system provides an innovative listening environment.
In addition to playing and streaming ultra-high-quality music, it offers a variety of services including 4K high-definition video playback, music orientated YouTube listening, Pod casts, various radio broadcasts around the world, Cd playback and ripping.
