ADI-2 FS © RME
To maintain the full dynamic range within the best operating level, RME's ADI-2 FS includes
electronic switches, which give control over input and output level via two keys from the front
plate, for a perfect adaptation to the 4 dBu, +13 dBu and +19 dBu. Two compact level
meters provide 6 LEDs each. Multiple brightness stages and peak hold functionality make read-
ing and adjusting input levels easy and convenient.
The ADI-2 FS provides all sample rates between 32 kHz and 192 kHz. The unique Intelligent
Clock Control technology (ICC) offers a flexible operation with internal clock and the digital input
signals. Furthermore, RME's SteadyClock technology guarantees exceptional performance in
all clock modes. Thanks to a highly efficient jitter suppression, the AD- and DA-conversion
always operates on highest sonic level, being completely independent from the quality of the
incoming clock signal.
4. Power Supply
In order to make operating the ADI-2 FS as flexible as possible, the unit has a universal DC
input socket, accepting voltages from 6 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 this regulator feeds further high.efficiency switching
regulators and super low-noise linear regulators. Therefore the ADI-2 FS achieves its technical
specs even with less optimal power supplies. Or in other words: the choice of power supply 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 FS 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.
* The highly efficient, internal switching power supply actually enables operation of the ADI-2
FS from 6 Volts. When used with batteries or rechargeable batteries, but also with other power
supplies (e.g. 9 Volts), there is a very low switch-off threshold and thus high operational
reliability. In continuous operation, however, the typical operating voltage should not fall below 9
volts. An overvoltage fuse is activated if the operating voltage exceeds 15 Volts. Since the fuse
may be destroyed, input voltages higher than 15 Volts must be avoided.
