With the AD-86D, Tonewinner offers a Class A integrated stereo amplifier rated at 2x120W into 8Ω, and relying on TTC-5200/TTA1943 transistors and 1678 OPA to deliver sound reproduction that's both precise and warm. Its extensive connectivity means this amplifier can be integrated into many different configurations, even benefiting from Bluetooth connectivity. Its integrated AD-1955 DAC chip enables the AD-86D to handle and convert signals up to PCM 24bit 192kHz, DSD up to DSD128.
The amplifier stage of the Tonewinner AD-86D features 8 Toshiba TTC-5200/TTA1943 transistors in a Class A circuit. These enable the amplifier to deliver a generous 120W RMS per channel at 8Ω. Furthermore, a total of 9 Texas Instrument OPA 1678 are included to deliver warm-to-ear sound reproduction.
The Tonewinner AD-86D benefits from a large number of inputs, both analog and digital, to fit into all possible audio installations. On the analog side, no less than 3 stereo RCA inputs are available. On the digital side, in addition to 3 coaxial inputs, the AD-86D offers a Mini-USB PC input, a USB-A input, a Toslink optical input, an HDMI ARC input and an SD port. Furthermore, the AD-86D features a subwoofer output, opening up the possibility of a 2.1 installation.
The AD-86D amplifier's Bluetooth functionality lets you enjoy stable, low-distortion, low-latency wireless transmission, so you can connect your smartphone or tablet.
With its numerous digital inputs, the Tonewinner AD-86D is naturally equipped with a digital/analog conversion section. This embeds an Analog Devices AD1955 DAC chip, decoding PCM audio streams up to 24bit 192kHz, DSD up to DSD128, and ensuring an SNR and dynamic range of 120dB.
The Tonewinner AD-86D is equipped with a highly accurate NJW1194 stereo volume controller. It enables efficient adjustment of sound level, ensuring low noise and distortion. Sound level adjustment is performed in 0.5 dB steps.
U-shaped rings on the AD-86D's connections allow it to be used as an integrated amplifier. Removing these rings simply allows it to be used as a pure power amplifier within a complete sound system. This amplifier's immense versatility means it can meet most of your needs.
To deliver this level of power, the Tonewinner AD-86D is equipped with a large power supply, including a high-performance toroidal transformer rated at no less than 400W. 6 large filter capacitors with a total capacity of 57400µF ensure a clean, stable electrical signal.
The internal design of the AD-86D has been thought out to physically separate the different sections of the device, thus ensuring excellent isolation. This design effectively limits interference and noise.
A dedicated control app makes it easy to navigate between your different sources. The mobile app interface also features a bass and treble adjustment menu, allowing you to fine-tune sound reproduction to your personal taste. It also supports file folder management, making it particularly handy for playing files on USB keys and SD cards.
