Product details:
This power supply uses 6 LT3045 parallel stabilized transformers, 50W sealed transformers, and a maximum output current of 3A. Compared with switch mode power supplies, the background is quieter and the sound is more transparent Suitable for Raspberry Pi, DAC, Digital interface, player, etc.
Fully balanced Class A symmetrical circuit.
treble, bass, and left-right balance adjustment.
The balanced amplifier and RCA amplifier modules are independent and do not interfere with each other.
2 transformers for power supply.
New electronic filtering technology.
Multi channel independent transistor voltage stabilization design.
Secondary amplifier circuit design to further reduce noise.
Fully symmetrical circuit design, stable performance.
Strict pairing of transistors for a quieter background.
Real balanced amplifier circuit design.
5 independent intervals to isolate interference between circuits.
Electricity is the mother of sound, and this preamp uses fully independent luxury power technology.
ELNA high-quality audio capacitor.CLC filtering method.
Japanese ALPS motor potentiometer, more linear and precise control of volume, better smoothness of left and right channels.
NEC relays from Japan ensure signal purity Reject the sound dye.
