- Page 2 A. Introduction ES9038Q2M Dual Mono II is the third-generation audiophile grade core ESS DAC board. Based on the latest ESS SABRE32 reference DAC technologies, it can provide the highest possible sound quality and performance for audiophile DIYers at reasonable cost. User can run this DAC at either default ASRC mode or the advanced SYNC clock mode when works with a FifoPi.

• Two high quality MCLK U.FL connectors pre-installed at both top and bottom side of the PCB, which not only makes the installation much easier but also makes it possible to use a shorter coaxial MCLK cable • Can use Audiophonics I-Sabre as Linux driver for better performance when uses the new MonitorPiPro as the controller •... - Page 4 E. Getting started with the default low-cost ASRC mode DAC 1. Install a RaspberryPi to a PurePi power supply (Optional but recommended) 2. Install the ES9038Q2M Dual Mono II on top of the RaspberryPi using 11mm standoffs. Connect two wires to the J2 of the DAC from the high quality 3.3V battery output J2 of the PurePi.

Also, once you have enabled True Sync mode on the 9038Q2MPi, the lock LEDs stay on continuously. Enable True Sync mode on your 9038Q2M by: 1. Selecting “True SYNC with DPLL stopped” in the ESS Controller at the “Normal/True SYNC mode” setting panel. 2.
- Page 9 Experiment with the settings of your ES9038Q2MP Dual Mono II using the ESS Controller Many of ES9038Q2MP Dual Mono II settings can be programmed using the ESS Controller. Some that make a difference sonically include DPLL bandwidth for both PCM and DSD format, the seven preset FIR filters, OSF bypassing, IIR bypassing.

- Page 12 Installations: - Install the ReceiverPi DDC on to PurePi through an GPIO female to male connector and 17mm standoffs. Install a Amanero Combo384 or compatible USB interface on to the bottom side of the ReveiverPi DDC using a 12mm standoff. And then install the other boards using 13mm standoff as in the picture. - Connect 3.3V wires from J2 of UcPure to both J5 of FifoPi clean side and J1 of the ES9038Q2M DM II DAC - Connect U.FL coaxial cable from MCLK of FifoPi to J11 of the ES9038Q2M DM II DAC - Connect the control cable from J6 of the MonitorPi Pro to J7 or the ReceiverPi DDC...
- Page 13 Installations: Please follow the diagram. Possible upgrade: - Power the FifoPiQ7 clean side and the ES9039Q2M Dual Mono II DAC by two independent UcPure MkIII Note: Both the SC-Pure clocks and the UcPure MkIII power supplies are all significant to the sound quality.
