DAC 32bit 768kHz / I2S & SPDIF
Audiophonics offers you the successor of the DAC I-Sabre 9028 boarding this time the decoding chip ES9038Q2M. This version offers remarkable sound performance, thanks to the Hyperstream II architecture, traditionally reserved for professional devices.
Following its predecessors, the ES9038Q2M offers exceptional sound performance thanks to components selected to ensure the greatest accuracy and precision in the restitution without sounding aggressive.
This version is based on recognized technologies. It also benefits from Hyperstream II, significantly improving dynamic range while reducing jitter and unwanted noise.
The design includes an ultra low phase noise crystal as clock for ES9038Q2M.
"The AUDIOPHONICS DAC I-Sabre ES9038Q2M finally brings good performance to HAT DACs. It rivals the performance of the higher priced DACs from Allo and Orchard Audio but at lower cost."
Like the previous ES9028Q2M, the ES9038Q2M has been designed to mount on a Raspberry Pi, thus providing the best possible output quality for a compact player.
It is compatible with other GPIO Raspberry format cards as well. Moreover it is possible to connect it to any I2S or SPDIF source. (USB interface, DSP ..)
The card offers an encoder-controlled hardware volume control, with an OLED screen display, allowing it to operate in complete autonomy.
Specific driver installation is optional and will allows you to control the volume or change the input source from Linux.
Thanks to a built-in microprocessor, the I-Sabre 9038Q2M is able to automatically detect the format and sampling rate of the source and automatically adapt to it.
It automatically detects if the source is 16bit / 24bit or DSD DOP
This CPLD chip control maintains high stability while preventing decoding problems as well as the appearance of listening artifacts.
The ES9038 I-Sabre board has two 9J NJM 2114 bipolar operational amplifiers powered by 9V for the C conversion section.I / V voltage, which allows a high quality of analog output.
A last AOP NJM 2214 used in buffer finalizes the analog output stage and ensures an optimal restitution.
This converter has the potential to evolve into a complete solution. By way of example, an OLED screen dedicated to displaying the source, the volume and the bitrate can easily be added.
We can also add an encoder to control the volume of the DAC to avoid loss of quality inherent software volume management.
Warning: This product contains only the Audiophonics I-Sabre ES9038Q2M DAC. The RaspBerry Pi, OLED screen and rotary encoder are sold separately.
The rotary encoder only works if the OLED display is also present.
Used in conjunction with a Raspberry Pi, the I-DAC Sabre ES9038Q2M benefits from a complete dematerialized streaming solution.
Audiophonics 9038Q2M driver is supported by Raspberry Pi kernel since version 4.19.34, which greatly facilitates the installation, and provides instant access to the hardware volume control, filter management, and input selection (I2S / SPDIF) .
(Dtoverlay = i-sabre-Q2M in config.txt)
To date (June 2019) the selection of the driver is built in:
Volumio offers an efficient and highly intuitive web control interface, ideal for getting started. This is the ideal option to easily obtain a powerful and easy-to-use audio / decoder player.
Moode Audio is a solution based on MPD like Volumio.
It allows reading files, radios, flow UPNP and even Qobuz (controlled UPNP)
The software solution allows use DietPi Logitech Media Server / Squeezelite and / or ROON.
It is also an effective working basis to install other applications, however, require some knowledge (SSH connection) to go further.
Picore Player is a powerful Squeezelite/LMS solution. It is easy to use, to install and to configure. This software solution can access all the DAC fonctions to enjoy every feature offered by the I-Sabre card.
Alsamixer control interface under DietPi
The ES9038Q2M driver is also compatible with the Volumio solution via a manually installable plugin.
Volumio offers an efficient and highly intuitive web control interface, ideal for getting started.
This is the ideal option to easily obtain a powerful and easy-to-use audio / decoder player.
This DAC card has a micro-controller which is very helpful to set basic functions. Any user can control it with an Arduino or any I2C controler for in housing integration.
The card allows multiple control thanks to 4 possible I2C addresses that can be reached with jumpers JP1 & JP2 :
Once connected the following registers are accessible (read-only) :
Adresse_I2C = 0x48;
VarVolume = 50;
Wire.beginTransmission(Adresse_I2C);
Wire.write(0x20);
Wire.write(VarVolume);
Wire.endTransmission();
The DAC-ISABRE is 24/192 compatible with the RPI-DAC driver and up to 32bit 384KHZ with its driver and distributions using an optimized audio kernel. (Volumio, Dietpi ...)
It can also read DSD64 / DSD128 DOP with solutions like Volumio and Logitech Media Server
SPDIF input accepts PCM format up to 24/192 and DSD 128 DOP.
I2S Input can accept up to PCM 32/768k and DSD 512 DOP. The use in addition to an Allo KALI is not compatible with the DSD mode.
