Tonewinner introduces the all-in-one AD-89D Class AB integrated amplifier. This 2.1 channel amplifier features a CD player, high-fidelity Bluetooth reception and an HDMI ARC port. Powerful and versatile, the Tonewinner AD-89D is capable of delivering up to 2x 130W into 8 ohms and functions as a CD player, multimedia player/DAC, and integrated amplifier or power amplifier. A wide selection of connectors makes it easy to integrate into any audio system.
This Tonewinner amplifier adopts a high-speed, low-distortion Class A amplifier circuit with powerful dynamic potential and excellent dynamics. It’s also worth noting that the internal structure separates the power stage from the input signal and signal processing stages. The left and right channels are also processed independently of each other. This structure significantly reduces the risk of interference and noise. The AD89-D power supply uses a 350 VA toroidal transformer and 40,000 µF capacitors. At least 8 high-precision, powerful matched tubes are used for the output stage.
The AD-89D’s U-ring connectors allow it to be used as an integrated amplifier. Removing these rings allows it to be used as a pure power amplifier as part of a complete sound system. The enormous versatility of this amplifier means that it can suit most of your needs.
A dedicated control app makes it easy to navigate between different sources. The mobile application interface also has a TV settings menu. It supports up to 8 levels of file folder management, making it especially convenient for playing files on U disks and TF cards.
The AD-89D’s digital inputs include a USB-B port with a digital interface that supports 24-bit 48 kHz PCM. This way, you can enjoy high-definition streams through a source such as a computer.
The AD-89D amplifier’s Bluetooth function allows you to enjoy stable wireless data transmission with low distortion and latency, so you can connect your smartphone or tablet.
The HDMI ARC port and subwoofer output allow you to integrate the AD-89D into your home theater system, delivering more immersive audio with a powered subwoofer.
