Eau Rouge CFRP power supply box 8 ports ER-PBZ

Eau Rouge ER-PBZ | Top 60t CFRP power supply box

High-end power reference for ultimate quietness and dynamics

ER-PBZ is a power supply box for high-end users that was designed with cost in mind, in order to fundamentally eliminate noise interference between digital and analog systems and to thoroughly control chassis vibration.

Digital/analog completely separate structure

Powering digital and analog devices from separate power lines is critical to reducing noise interference.

ER-PBZ adopts a structure in which 4 digital ports and 4 analog ports are completely separated from the IEC inlet on the input side, creating an ideal power supply environment. It fundamentally prevents digital noise from entering analog equipment, and maximizes the quietness of the sound background.

Integrated molding with 60t high elasticity CFRP housing

The casing has an elastic modulus approximately three times that of general CFRP**60t class high modulus carbon fiber*Use *. As the resonant frequency increases, the vibration damping speed is dramatically improved.

Molded integral structure: Since CFRP is not strong enough to be machined, we use extremely expensive one-piece molding. It ensures a high level of rigidity that is incomparable to adhesive structures, and completely eliminates the muddy sound caused by the housing.

Internal loss advantage: The characteristics of CFRP allow it to absorb minute vibrations transmitted to the housing at a high level.

Active vibration countermeasures with mechanical grounding structure

Even if a material has a high resonant frequency, its effectiveness will be limited without structural measures.

ER-PBZ quickly releases minute vibrations generated in the casing itself to the ground**Mechanical grounding structure** is adopted. ER-SX is used for the four-point support spikes, which are securely fixed with special CFRP screws. The sound foundation is solid and stable, and dynamics are improved without compromising performance.

Tunnel Structure Enveloping the AC Plug and Highest Quality Components

Noise-Blocking Tunnel: The tunnel structure built into the body prevents the plug section from being exposed to external noise (high frequency and electromagnetic waves). It maximizes the performance of high-end AC cables that are not shielded.

Carefully Selected Parts:

• Solid Silver IEC Inlet
• Eau Rouge ExclusiveUltra-fine Pure Copper Litz Wire “No.411”
• Thick Plated Walloutlet**“ER-PSEXmk5”**
• Every screw and component has been selected through meticulous listening tests, resulting in a top-tier configuration that compromises nothing on sound quality.

Flexible Expansion Design for the Future:

Ample space is secured inside, allowing for future additions of filters or transformers, use of hard-to-route cables, and flexible expansion to pursue further sound quality improvements.

Noise Countermeasures and Sound Separation (Effect of Separate Structure):

• Digital and analog noise interference is perfectly resolved, significantly deepening the background quietness.
  The completely separated input structure is effective, especially improving transparency during analog playback.
  
• Thanks to the “tunnel structure” around the AC plug, noise is blocked and resolution is enhanced.
  Even the finest nuances become clearly perceivable, and sound separation is outstanding.
  

Ultimate Vibration Control (CFRP Enclosure × Mechanical Grounding):

• The combination of 60t CFRP and mechanical grounding is impressive, instantly managing even subtle vibrations. As a result, the background becomes deeply quiet and the contours of sound images are sharply defined.
  
• The low-end foundation is stable, producing tight and controlled resonance.
  The overall dynamic range of the sound deepens, allowing music to unfold powerfully and expansively.
  

Benefits of Top-Tier Components:

• Meticulously chosen parts like the solid silver inlet and No.411 Litz wire ensure highly pure signal transmission.
  Without adding any unnecessary coloration to the sound, they fully extract the information contained in the music.
  
• The chassis, featuring an integrated molded structure, thoroughly eliminates power-related haze and incidental noise, supporting a sound that is clear down to the finest details.
