Product description:
The decoder uses a piece of ES9038PRO decoding chip, there are eight
independent DACs inside the chip, which are used in two channels, and
four groups of DACs in one channel are output in parallel.
ES9038PRO
master clock 100M crystal oscillator: 0.1PPM high precision low phase
noise temperature compensated crystal oscillator.
The analog output uses OPA1612A*2 dual op amp and OPA604AP*2 single op amp.
High
resolution, clear and delicate sound, good mid-frequency density,
strong bass, great dynamics and a very wide sound field, three-band
balance is true, it is a decoder suitable for listening to all kinds of
music.
This machine is a DAC audio decoder and does not support reading and playing U disk, SD card and other carriers.
Features:
1.
Under the control of MCU, it supports coaxial (COAX), optical fiber
(OPT) and USB, IIS, BH Bluetooth switching, filter selection, 120-level
volume control, shutdown memory, and full-function remote control. The
upgraded LCD display with white and blue characters and black background
is clearer than the ordinary backlit LCD1602.
2.
Gold-plated RCA input and output sockets to ensure good transmission
performance, 25M bandwidth optical fiber receiving head, support 192K.
3.
Fully upgrade 0.1ppm high-precision temperature compensation active
crystal oscillator, independent regulated power supply, the decoder
works more stable, and the sound quality is better.
4.
The analog output uses dual op amp OPA1612A*2/single op amp OPA604AP*2,
and Zhengling Seiko gold-plated op amp socket. 4 groups of independent
I/V circuits, with RCA and XLR fully balanced outputs, can be connected
to higher-end power amplifiers and active speakers.
5.
The 5.1 version QCC5125 Bluetooth receiver is more stable than the
previous generation CSR8675. It supports LDAC and APTX-HD
high-specification reception. It uses ultra-high-speed buffer receiving
and switching chips to ensure high-purity signal transmission.
6.
Fully sealed ring type (O-type) transformer, zero vibration, zero
magnetic leakage, high efficiency, and no bull screaming. Fast recovery
rectifier diodes, original Ruby Rubycon, main filter capacitors for
audio from Japan Chemical Industry.
7.
As many as 13 sets of voltage regulator circuit modules, the core power
supply of ES9038PRO uses low-noise Linear Technology LT1963A and
ADP151-3.3, and the left and right channel analog power supplies are
independently powered. ON's industrial-grade voltage regulator chips
LM317BT and LM337BT provide pure power for the op amp.
8.
WIMA, Siemens, ERO and other fever capacitors. The analog part of the
circuit uses Philips VISHAY 0.1% high-precision metal film resistors.
9.
Increase the IIS (I2S) input (can be connected to the digital turntable
with the corresponding IIS output, this interface is not a video HDMI
interface, and cannot extract HDMI audio signals), using a high-speed
buffer receiving switch chip to ensure high-purity signal transmission.
10.
The switch protection circuit composed of imported signal relays can
effectively protect your beloved power amplifier and speakers from
impact. (The decoder without relay protection will produce a big impact
sound when it is switched on and off, which will cause great damage to
the power amplifier speakers.)
11.
Add power MEI filter to effectively reduce the interference of the
mains power to the decoder, the background is more quiet, and the sound
is more pure. The 110/220V voltage switch is convenient for use in
various regions.
Because it is a brand new component, the sound quality is tight at the
beginning, and the sound quality tends to be fine and full after aging
for more than 50-100 hours, which will be greatly improved.
