Product details:
This decoder uses an ES9038PRO chip with eight independent DACs internally, applied to two channels, with one channel having four parallel DAC outputs.
Support DSD hard decoding.
IIS (I2S) - HDMI Digital Audio Interface.
QCC5125 Bluetooth 5.1.
Use POA1612A * 2 dual operational amplifiers (I/V conversion and XLR balanced output) and POA1611A * 2 single operational amplifiers (LPF low-pass filtering/RCA output).
High resolution, clear and delicate sound, good mid frequency density, strong bass, wide dynamic sound field, and realistic three-stage balance It is a decoder suitable for listening to various types of music.It does not support reading and playing USB drives, SD cards, and other media.
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. Theupgraded LCD display with white and blue characters and black background is clearer than the ordinary backlit LCD1602.
Gold-plated RCA input and output sockets to ensure good transmission performance, 25M bandwidth optical fiber receiving head, support 192K.
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.
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.
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.
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.
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.
WIMA, Siemens, ERO and other fever capacitors. The analog part of the circuit uses Philips VISHAY 0.1% high-precision metal film resistors.
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.
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.)
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.
