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.
