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.

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
