The RD160 offers a digital processing core module that precisely processes digital signals, an architecture to separate digital and analog signals and convert them transparently and precisely without distortion, a fully balanced design to maintain the highest signal purity, three power supply units to independently supply power to each circuit for clearer and more dynamic sound, and even a noise filter to vividly convey the finest details of the sound.

ROSE DPC(Digital Processing Core)™ Module
The digital stage of the RD160 is equipped with the ROSE DPC™ module, where all processing blocks are designed to maintain optimal signal accuracy and precision, ensuring the delivery of high-fidelity sound. This module precisely synchronizes digital signals input from various methods to a high-precision OCXO clock, aligning them as I2S signals. Especially when processing high-resolution audio signals, the module applies clock synchronization and locking processes to minimize jitter, resulting in accurate signal processing and natural, clean sound. Additionally, the circuit for the user interface and GUI configuration is completely isolated from the digital audio signal path, thoroughly eliminating signal distortion and interference. Through this design, the RD160 guarantees superior digital signal quality and ensures high-quality sound with compatibility across various digital formats.

ROSE NRA(Noise Reduction Analog)™ Filter

The analog stage, equipped with the ROSE NRA™ filter, achieves flat frequency characteristics even in the very low frequency range. As a result, the RD160 boasts a consistent frequency response across the entire spectrum without roll-offs, delivering clear and faithful reproduction of the original sound information in high-resolution audio, from deep and powerful sub-bass to the ambient details in the high-frequency range.

Three Customized Reference Linear Power Units

The reference linear power supplies in the RD160, developed in-house by ROSE, are engineered to achieve the highest sound quality using ULTRA LOW NOISE power chipsets. These power supplies independently feed the digital input stage and the left and right analog output stages, minimizing crosstalk and interference between sections. This design effectively suppresses noise across the digital processing, clock, and analog output circuits, ensuring signal integrity. By delivering stable power tailored to the specific needs of each stage, it enhances the DAC’s dynamic range and resolution, faithfully conveying even the most subtle details of the music. Additionally, the reduction of jitter maximizes the spatial characteristics of the soundstage, resulting in a wider and more precise soundstage with sharp imaging. Through this power supply design, the RD160 elevates audio clarity and dynamics, offering a deeply immersive listening experience.
