The integrated design of the power switch and volume control looks simple and aesthetically pleasing.
The special treble knob with a pass-through function offers higher playability.
The dedicated AUX/Bluetooth switch with red/blue indicator lights clearly displays the input mode.
Featuring 2*TL072 operational amplifiers—one for pre-amplification and the other for tone control—all components are processed using SMT technology for enhanced precision and stability in the circuitry.
High-speed stepless coupling capacitors, sealed in aluminum casings, offer superior heat dissipation and longer service life.
Under large heat sinks, 2*TPA3116 amp chips provide high driving power, strong heat dissipation, and stable operation.
The power purification system effectively suppresses electrical arcs and sparks, and provides surge protection during power-on/power-off.
Large-capacity solid capacitors deliver pure and efficient power supply.
Custom fully-enclosed output coils, wound with OFC wire and sealed in ferrite casings, reduce magnetic leakage and electromagnetic interference.
Supports APTX and APTX-HD, compatible with QCC3034 version: Bluetooth 5.0, works with both Android and iPhone devices, with a maximum transmission rate of 48K 24BIT.
The ES9018 decoding chip serves as the Bluetooth decoding chip, enabling Bluetooth to achieve Hi-Fi level sound quality
