Technology

Zero Feedback Design

Feedback is a factor that interferes with natural sound. It's not easy with a vacuum tube, but The Zero Feedback circuit has been completed.


Technology

Application of proprietary DFD (Direct Full Difference Circuit) circuit

In vacuum tube amplifiers, we have completed a unique Direct Full Difference vacuum tube circuit.


Technology

The Importance of Power Design

All of Fjord's products pay special attention to the design of the power supply. We intentionally applied a classic filter, By focusing on minimizing noise and providing sufficient power, it provides sufficient gain for actual sound.


Military standard PCB design

Vacuum tube amplifiers that maintain high pressure and temperature should not use general PCBs. Fjord Audio has secured quality in terms of lifespan and heat generation through the PCB by applying military-standard copper plate thickness of 105㎛.


Application of unique UTS (Upper Tube Set) method

We use a unique UTS mechanism structure to reduce harmonic noise that may occur in vacuum tubes.


Technology

Automatic bias check and application of various protection circuits

P150 always checks the bias of the output tube to maintain the best condition and operates an automatic protection protection circuit in the event of overvoltage.
All amplifiers basically employ Standby Power and Mute circuits.


Use of dedicated FJORD vacuum tube

Uses specially selected Fjord vacuum tubes, Quality was secured through pair matching and aging in the production process.
