Description

The decoder uses an ES9038PRO decoding chip. There are eight independent DACs inside the chip, which are used in two channels, and four groups of DACs are output in parallel for one channel.

All aluminum alloy chassis, external dimensions: width 218mm height 60mm depth 199mm

Packing weight: 2.5Kg

ES9038PRO main 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, large dynamics and a very wide sound field, three-stage 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.

(1) Under the control of MCU microcontroller, 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 on a black background is clearer than the ordinary backlight LCD1602.

(2) Gold-plated RCA input and output sockets to ensure good transmission performance, 25M bandwidth fiber receiving head, support 192K.

(3) Fully upgrade the 0.1ppm high-precision temperature-compensated active crystal oscillator, independent regulated power supply, the decoder works more stably 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 independent I/V circuits, with RCA and XLR fully balanced outputs, can be connected to higher-end power amplifiers and active speakers.

(5) QCC5125 Bluetooth receiver of version 5.1 is more stable than the previous generation CSR8675, supports LDAC, APTX-HD high-standard reception, uses ultra-high-speed buffer reception, and switches chips to ensure high-purity signal transmission.

(6) The fully sealed ring type (O type) transformer has zero vibration, zero magnetic leakage, high efficiency, and eliminates the sound of bulls. Fast recovery rectifier diode, original ruby Rubycon, main filter capacitor for Japanese chemical audio.

(7) There are up to 13 sets of voltage regulator circuit modules. The core power supply of ES9038PRO adopts low-noise Linear Technology LT1963A and ADP151-3.3, and the left and right channel analog power supplies are independently powered. ON company's industrial-grade voltage regulator chip LM317BT, LM337BT provides pure power for the operational amplifier.

(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) Add IIS (I2S) input (can be connected to a digital turntable with corresponding IIS output, this interface is not a video HDMI interface, and cannot extract HDMI audio signals), and use 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 large impact sound when it is switched on and off, which will cause great damage to the power amplifier speakers.)

(11) The power supply MEI filter is added to effectively reduce the interference of the mains on the decoder, the background is quieter, and the sound is more pure. 110/220V voltage switch, convenient for use in various regions.

Because it is a brand-new component, the sound quality is tight at the beginning. After aging for more than 50-100 hours, the sound quality tends to be delicate and full, and there will be a greater improvement.

Compatible with original Italian Amanero and XMOS digital interface.

The USB module equipped with this machine is the domestic version with the same scheme as Amanero, and the package without USB module does not have this accessory.

The function of the USB module is to connect the decoder to the computer or mobile phone OTG as an external USB sound card.

Note: The USB module cannot upgrade the firmware without authorization. If the firmware is cleared by itself, the firmware cannot be flashed through the official Tools. The store is not responsible for the behavior and consequences of this self-clearing the firmware.

Installing the driver requires a certain knowledge of computer operation, you can refer to the tutorial we provide.

USB interface system support: (the decoder is used as an external USB sound card)

Support WIN XP-WIN10 32/64 bit (drivers need to be installed) Support DSD64-512.

Supports Linux, Mac OS (no need to install drivers above 10.6), Raspberry Pi, Tamiflu system (supports DSD64-128).

Support Apple IOS (ipad, iPhone need to add camera kit or OTG conversion cable, no need to install driver), support DSD64-128.

Support some Android platforms, need to add OTG conversion cable, no need to install drivers, support DSD64-128.

Mobile devices are recommended to use Haibei Music Player.

IIS (I2S) is not a video interface and cannot extract HDMI audio signals. It must be consistent with the definition of the IIS output interface of the digital turntable.

At present, the data broadcasts supported by the interface are: JueLing, Red Core, Olaer, Gothic interface, Musheng interface, etc. (The HDMI cable is recommended to be within 0.5 meters, the shorter the cable, the smaller the loss)

ES9038PRO digital input supports formats:

COAX (coaxial) OPT (optical fiber): (can be connected to CD players with digital output, digital players, etc.)

PCM16-24bit44.1-192 KHz, DSD64 (2.8M) Dop mode

USB (Italian Amanero digital interface with the same scheme):

PCM16-32bit44.1-384 KHz, DSD64-128 (Dop or Native mode) Windows system DSD64-512 (Native mode)

IIS (I2S):

PCM16-32bit44.1-384 KHz, DSD64-512 (Native mode)

Bluetooth reception (depending on the support of the connected device):

LDAC: PCM24bit96K

APTX HD: PCM24bit44.1-48K

Bluetooth instructions: switch the decoder input to BH, turn on the mobile phone Bluetooth to search for the Bluetooth device: QCC5125, pair and connect.

LDAC is an encoding technology developed by Sony that allows streaming audio at 24bit96K (also known as high-resolution audio) over a Bluetooth connection at speeds of up to 990 kbit/s to easily surpass the CD standard. However, there is another premise here, that is, two devices connected by Bluetooth (such as mobile phone and Bluetooth receiver/decoder) need to support LDAC technology at the same time, so that LDAC high bit rate transmission can be realized. The disadvantage is that the stability is relatively poor, it is easy to be interfered, the transmission distance is not far, and there is no obstruction of 5-8 meters.

The "Guardian Angel" of Bluetooth - APTX® Technology was born! It significantly reduces the bit rate by re-encoding and decoding the audio to be transmitted, without affecting the sound quality or causing the delay of transmission, making the Bluetooth stereo listening experience a revolutionary leap. Therefore, with APTX, you can enjoy pure wireless audio with CD-quality sound anytime, anywhere.
