The Tonewinner AD-66D PRO is an efficient and versatile Class A amplifier with a proven technical foundation for musical and detailed sound. Its circuitry uses audiophile-grade components to ensure excellent performance, including low noise and distortion. It also provides a complete set of connectors to meet the vast majority of needs for home audio integration.
The AD-66D PRO's Class A amplifier stage is based on the use of two pairs of high power Toshiba TTA1943/TTC5200 transistors, allowing to develop 2x80W under 8Ω or 2x135W under 4Ω. The amplifier also benefits from a particularly careful architecture, ensuring a low level of distortion, thus revealing a musical and rich sound. Moreover, the AD-66D PRO provides a subwoofer output allowing the addition of a subwoofer within a 2.1 system. The speaker output is equipped with a protection circuit, effectively securing your equipment.
With its numerous digital inputs, the Tonewinner AD-66D PRO is of course equipped with a digital / analog conversion section. This one embeds an Analog Devices AD1955 DAC chip, decoding PCM audio streams up to 24bit 192kHz and ensuring an SNR as well as a dynamic range of 120dB.
In order to meet the vast majority of needs, the AD-66D PRO offers a full range of connectivity, including input with USB, optical, coaxial, HDMI ARC, a Micro SD port, stereo RCA but also thanks to a Bluetooth 4.2 receiver using an ATS2825 chip. It is thus possible to broadcast and control your music remotely, from a smartphone for example, directly to the amplifier.
