Fully discrete NMOS

voltage regulator circuit

Dual high-current IRFZ34NPBF MOSFETs are used in a parallel configuration to lower internal resistance. The result is improved dynamic range and ensures that every nuance of the audio is faithfully preserved. With fully discrete voltage regulator circuit and high-precision reference, ultra-low noise and lightning-fast transient response are achieved—all while effectively minimizing heat generation.

An integrated relay manages the transformer’s output voltage to provide a precise match for both 12V and 15V settings. Such a design maximizes power efficiency and significantly reduces heat generation during operation.

Precision thermal control

넳 넲

The device uses a 46W low-noise, low-frequency toroidal audio linear transformer. Toroidal transformers have innate advantages: the toroidal core made with non-oriented silicon steel strips provides high efficiency and low eddy current loss, while the corner-free coils result in a more uniform magnetic field and less leakage. Thanks to this power supply, the WARMER R2R is fed clean power that allows it to produce pristine, immaculate sound.
