AD-86D

Class A Hi-Fi Integrated Amplifier

Generation Update History

Multiple Input Sources 

Original App Control Interfaces

15-meter Bluetooth Transmission

High-speed & stable, low distortion, energy consumption & latency.

Switch any music apps and platforms you want.

128G for Lossless Sound Effect

Support 128G USB disk & TF card and support APE, FLAC, WAV, MP3, WMA formats.

HDMI-ARC for Better Transmission

Support HDMI ARC to connect to TV for better sound.

Multiple Connection Options

1 way USB Audio for PC, 1 way optical input and 3 way coaxial inputs, which handles PCM192kHz/24bit for digital devices.

One-step Integrated Amplifier & Amplifier Switch

The PRE OUT jacks and AMP IN jacks are connected by a short circuit ring to make signals of this machine and make it an integrated amplifier. Detach the short circuit ring and you will get an independent amplifier, so input signals can go through the “AMP IN” terminal. 

Subwoofer Treble-bass Adjustment

Multi-chamber Internal Layout

The areas of power supply, input, power storage, and left & right amplifying channel are separated into chambers so as to reduce the interference of free electromagnetic wave.

Hi-Fi Circuit Design

The pre-amplifier part adopts high quality operational amplifier, and the amplifier part adopts a typical single-ended input, double-ended output differential amplifying circuit, which has low input noise and greatly improves the voltage gain. 

The common-base amplifying circuit is used to improve the circuit performance, and after the temperature compensation and current-expand part, the amplifying output circuit give strong support to drive the speaker units to out put sound. 

High Capacitance Filter Capacitor

6 customized filter capacitors in total of 57,400μF capacitance is going to give strong support.

High Power Toroidal Transformer

400VA high power ring transformer works as the power source

and gives high power support to drive the whole machine.

AD-1955 DAC Decoding Chip

It supports 24-Bits, up to 192 kHz sample rate PCM audio data

 and about 120 dB SNR/DNR (not muted) at 48KHz sample rate

(A-Weighted) with dependent digital filter and D/A converter.

The flexible serial data input port allows for glueless interconnection

to a variety of devices and also reduces mistakes during decoding.

High Power Toshiba Transistor

A total of eight TTC-5200/TTA1943 high power Toshiba transistors work together to offer bright treble, analytical mid-range and sonic bass. 

OPA1678 Operational Amplifier

It adopts nine OPA1678 optional amplifiers from

TI company to form full balance amplifying

structure to bring analytical and warm sound.
