User’s Guide ADI-2 Pro FS – v 2.5

6. Power Supply

In order to make operating the ADI-2 Pro as flexible as possible, the unit has a universal DC

input socket, accepting voltages from 9.5 Volts up to 15 Volts. An internal switching regulator of

the latest technology with high efficiency (> 90%) prevents internal hum noise by operating

above audible frequencies. Internally the switching regulator is followed by standard linear regu-

lators, followed by super low-noise linear regulators. Therefore the ADI-2 Pro achieves its tech-

nical specs even with less optimal power supplies. Or in other words: the choice of power sup-

ply is not critical.

Still the unit includes a high-quality switching power supply, 12 V / 2 A, which not only accepts

any mains voltage between 100 V and 240 V (usable world-wide), but is also fully regulated

against voltage fluctuations and suppresses line noise. Additionally it only weights 150 g in spite

of its high power of 24 Watts.

The DC input of the ADI-2 Pro also allows for the use of a rechargeable lead-battery or LiPo

instead of a power supply, for completely independent mobile operation and ground isolation. A

matching connection cable (power jack to terminals 6.3 mm) is available from RME. Special

power banks in the range of 10,000 mAh and up can be found equipped with a 12 V output.

These offer a perfect solution for mobility as well as ground isolated operation, for small money.

7. Firmware Update

The ADI-2 Pro might receive improved features or bug fixes by a firmware update. This update

will be available from the RME website, section Downloads, USB. Download the tool that

matches your operating system (Mac or Windows), then unpack the zipped archive.

The Flash Update Tool updates the

firmware of the ADI-2 Pro to the latest

version. Under Windows it requires an

already installed MADIface series

driver, which is found on the same

download page.

Start the Flash Update Tool. It displays

the current revision of the ADI-2 Pro

firmware, and whether it needs an

update or not. If so, then simply press

the 'Update' button. A progress bar will

indicate when the flash process is

finished (Verify Ok).

After the update the ADI-2 Pro needs

to be reset. Push the standby button to

switch it off for 5 seconds.

When the update unexpectedly fails

(status: failure), the unit's Safety BIOS

will be used from the next boot on, the

unit stays fully functional. The flash process should then be tried again.

The flash process does not affect user data like sample rate choices, EQ settings or Setups.

Returning to Factory State

In case a total reset is desired: hold encoder 1 and the VOL button pushed while turning on the

unit. This will reset all memory to factory default. Setups and EQ Presets stored by the user will

not be deleted.
