Moondrop Dawn Pro 2 EQ app for Android
Contour EQ is a free, open-source Android app that reads and writes the parametric EQ stored inside the Moondrop Dawn Pro 2. The EQ stays in the dongle, so once you switch the custom EQ on with both volume buttons, it works in every app and on every device you plug it into.
Stable 1.6.6

What Contour does not do on the Dawn Pro 2
- Firmware updates.
- Writing over the DAC's own presets. Contour writes only to the active PEQ bank and writes nothing while the DAC is on one of its presets.
- Changing GLOBAL GAIN. The DAC ignores the write, so the DAC page shows it read-only.
- Hardware volume and resetting the DAC.
- The Dawn Pro 2 that reports the USB name DAWN PRO 2, with a space. It is a different version, and Contour does not support it.
Contour EQ and Moondrop Hub
Moondrop's own tool for the Dawn Pro 2 is Moondrop Hub. Contour sends the same frames as Moondrop Hub to the DAC's active PEQ bank and reads every band back. Moondrop Hub has a GLOBAL GAIN control; Contour shows GLOBAL GAIN read-only, because the DAC ignored the write in testing. Contour runs on the Android phone the dongle is plugged into, keeps your profiles in a library on the phone and needs no internet or account.
Using Contour with the Dawn Pro 2
- Switch the custom EQ on in the Dawn Pro 2: hold both volume buttons for 2 seconds. According to Moondrop it is off after every plug-in; the LED turns orange when it is on and red when it is off.
- Send a profile with HOLD TO SEND. Contour writes it to the active PEQ bank and reads every band back. While the DAC is on one of its own presets, Contour writes nothing.
- If HOLD TO SEND writes nothing, look at EQ INDEX on the DAC page: Contour writes only while the DAC is on the PEQ bank (index 7 or 9), not on one of its own presets.

Questions about the Dawn Pro 2
Is there an EQ app or software for the Moondrop Dawn Pro 2 on Android?
Yes. Contour EQ reads and writes the Dawn Pro 2's 8-band EQ and preamp from an Android phone. It is free and open source (Apache 2.0). Moondrop's own tool for this DAC is Moondrop Hub.
Does the EQ work on a PC or an iPhone?
Yes. The EQ is stored in the Dawn Pro 2, so it plays on every device you plug the dongle into, PCs, Macs and iPhones included, once the custom EQ is switched on with both volume buttons. You need an Android phone only to change it with Contour.
Can Contour update the Dawn Pro 2's firmware?
No. Contour does not update firmware. It reads and writes the EQ and the preamp, and shows EQ INDEX, GLOBAL GAIN and PRE GAIN on the DAC page.
Do I need a driver or root?
No. Android supports USB audio dongles out of the box, and Contour talks to the Dawn Pro 2 over USB after you allow it in Android's permission prompt. No root, no extra driver.
