DSD Decode Class A Hi-Fi Integrated Amplifier

Hi-Fi circuit

AD-3PRO+ adopts symmetrical differential common-emitter, common-base voltage input, differential amplifying and temperature compensation circuit, driving multiple Darlington transistors to form the complementary push-pull amplifying circuit. And the sound is transmitted via the BTL output configuration. Such circuit greatly improves the purity of music reproduction and preserves more details of each part of music.

30+years pursue in AD Series

AD-3PRO+ carries on the most popular functions of AD-2PRO such as DSD decoding, MM/MC phono and subwoofer balance output. It also achieves its update on the basic of AD-3PRO by adding USB-Audio port to offer more choice for audiophiles.

USB Audio 

It handles DSD512 high class audio format to achieve PC Hi-Fi.

Phono Interface, classic appreciation.

It supports MM/MC cartridges for easy compatibility.

The rich sound will take you back to classic time.

 

Balance Input

XLR audio port for less interface

and low distortion.

Subwoofer Output

XLR /RCA output port connected to an active subwoofer will truly meet the need of bass fans. 

Bi-wiring Connection

It supports standard connection and bi-wiring connection mode. When in the bi-wiring connection mode, treble and mid-bass are separately connected with the amplifier so as to reduce interference and improve sound effect.

Multiple Connections

Class A/ Class AB/ AUTO

AD-3PRO+ has three built-in circuit modes: Class A, Class AB and auto-switch between Class A & AB, which is one of the symbols of ToneWinner’s high-end Hi-Fi amplifier. Use the remote control to achieve one-click switch among these three modes.

High Power

165W for each channel to drive most famous speakers.

Use the remote control to achieve one-click switch between

integrated mode and purely amplifier mode.
