DAC Dual Mono 768kHz - 32bit PCM / DSD1024 Native & DOP256

IAN CANADA DUAL MONO MKII DAC ES9038Q2M HAT Raspberry Pi / I2S & SPDIF / PCM DSD


Ian Canada 9038Q2M dual mono DAC HAT is a very high level of DAC for Raspberry Pi. It uses two chips ES9038Q2M SABRE 32-bit each working in mono. That is to say that each of these chips uses 100% of its computing power for a single channel of the stereophonic signal for a sound restitution of exceptional clarity.

The ES9038Q2M Dual Mono DAC is remarquable because of its lack of output stage: This module is made exclusively for performing digital / analog conversion quality. It must be connected to an output stage that can be selected from existing compatible components or self-assembled according to your own specifications.

In other words: DAC Ian Canada Raspberry Pi is a hyper efficient DAC (double 9038Q2M), which imposes no particular output stage to the makers. They can then freely meditate the best integration strategy depending on the type of project solutions, budget and compliances.

Improvements to the ES9038Q2MPi Dual Mono DAC HAT MKII

  • Extended PCB for larger shielding and grounding zones.
  • Improved low-noise power supply filtering network for better sound reproduction.
  • New form factor with power supply connectors moved to a side edge of the PCB for more organized PCB configuration.
  • Power configuration jumpers allow the module to share an ultra-low ESR power supply (such as a UcPure III 3.3V) or to be powered separately.
  • MKI6-compatible software.
  • Can be used with the Audiophonics Linux driver for enhanced performance with the new PI PRO Monitor as controller*.
  • U.FL MCLK connectors on the top and bottom of the PCB allow the use of shorter coaxial clock cables.
  • Mounting holes for the new, high-sound quality, resistor-balanced I/V board.

Using the Audiophonics I-SABRE driver with your Rasberry PI

*To use the Audiophonics I-SABRE driver with your Rasberry PI, invoke the driver from /boot/config.txt with the command line dtoverlay=i-sabre-q2m or select the "i-sabre-q2m" driver from your Pi-based streaming solution.

Key features of the ES9038Q2MPi Dual Mono DAC HAT

  • 32bit SABRE32 DAC true dual mono architecture.
  • Supports up to 768KHz 16/24/32bit PCM, native DSD1024, and DSD256 via DoP and S/PDIF.
  • SYNC and ASRC dual clock mode.
  • External synchronous clock range from 22.5792MHz to 98.3040MHz. Or 100MHz internal asynchronous
    clock.
  • Control and register settings by external ESS controller or MonitorPi Pro.
  • Controller operates in isolated mode when used with FifoPi to eliminate ground loop and EMI noise.
  • Raw balanced current output enables use of a variety of external output stages such as the Transformer I/V, the standard OPA I/V or the OPA861 zero feedback balanced I/V.
  • Dual mono configuration can provide 389 Ohm ultra-low output impedance to get much higher dynamic output current than the normal single chip configuration.
  • Direct 3.3V power inputs ready for ultracapacitor power supply or LifePO4 battery power supply.
  • Independent lock LED indicators for both left and right DAC chips.
  • Can automatically switch between PCM, DSD, DoP and S/PDIF.
  • XO socket design makes it possible to swap/upgrade to better local clock.
  • Very easy to switch to SYNC modem by just removing local XO from the socket and plugging an U.FL MCLK cable.

Double ES9038Q2M


Dual Mono DAC Pi employs two DAC chip ES9038Q2M. It is not only ESS flagship product, it is also one of the best current material solutions for high-fidelity digital audio decoding.

It uses famous architecture HyperStream 32 BIT 768kHz and a support native DSD 1024. Dac chips are also equipped with advanced reconstruction filters and have an excellent finesse in dithering.


Optimised power supply

The basic module is powered by three separate power supply units. These form the symmetrical power supply stage, which is responsible for supplying each of the DAC chips with clean power. The DVCC, FCCA and AVCC rails are isolated. It is therefore possible to supply them independently with 3.3V / 100mA (minimum) for optimum performance, or to bridger them to use only one power supply. It is recommended to supply the DAC directly with 3.3V supercapacitor modules or LiFePO4 batteries, to obtain the best possible sound reproduction.

The 9038Q2MPi consumes about 50mA on average, with the MCLK 50MHz in asynchronous mode (default).

Synchronous or asynchronous clock

The module can use its own internal clock 100MHz (asynchronous) and can work with an external clock (synchronous) of 22.5792MHz to 98.3040MHz. Properly used, this second mode offers unmatched performance from the viewpoint of jitter. It will therefore naturally favored by the most discerning audiophiles.

When used in synchronous MCLK guide (e.g. mounted on a FifoPi with galvanic isolation and removable clocks), this dual DAC Mono 9038Q2M operates from an external clock signal. In other words, it is very easy to inject a clocks signal without requiring direct circuit modification  (just use a jumper to enable / disable async mode).

Note, however, that to enjoy the SYNC mode in all its qualities, it is necessary to set the bandwidth of the digital phase locked loop (DPLL). This operation requires an ESS controller (like the ECCS, specially designed for this or any driver capable of editing the register of a ESS9038Q2M chip).

Scalable DAC module


If the use of a ESS controller is perfect for fine-tuning the DAC chips (the controller Ian Canada FifoPi the same manufacturer allow the module to work TrueSync mode), there are plenty of upgrades that can be done by the user.

Depending on your goals you may :
- Install a FiFoPi / Isolator between Raspberry Pi and DAC
- If you can not work with a reclocker (FifoPi), the clock on the DAC itself is  removable.
- Install an ESS controller to change the DAC settings on the fly
- Customize the powering system to improve audio performance.
- Install an output stage suitable for your installation, its constraints and your personal preferences
