Page 4: Introduction
One of the main issues when working with an AD-converter is to maintain the full dynamic ran- ge within the best operating level. RME's ADI-8 PRO includes electronic switches of the newest technology, which introduce no additional noise or distortion to the audio path and op- erate as remote controlled level attenuators. -

-10 dBV is able to send and receive much higher levels. Hi Gain results in maximum level for professional users who prefer to work bal- anced and at highest levels. User's Guide ADI-8 PRO © RME... -

The ADAT optical inputs of the ADI-8 PRO are fully compatible with all ADAT optical out- puts. RME's unsurpassed Bitclock PLL prevents clicks and drop outs even in extreme vari pitch operation, and guarantees a fast and low jitter lock to the digital input signal. A usual TOSLINK cable is sufficient for connection. -

The TDIF interface and the DA-converters of the ADI-8 PRO support Emphasis. Please note that an Emphasis indication will not be stored or processed on the sound when doing digi- tal transfers between TDIF and ADAT, because the ADAT standard does not include Emphasis.

7, Clock Section). As soon as a valid signal is detected, the EXT LED is constantly lit, otherwise it is flashing slowly. Thanks to RME's Signal Adaptation Circuit, the word clock input still works correctly even with heavily mis-shaped, dc-prone, too small or overshoot-prone signals. Thanks to automatic signal centering, 300 mV (0.3V) input level are sufficient in principle. -

In clock mode D/A INTERNAL the clock choices EXTERNAL and INPUT of the AD-section do not make sense, as the clock at the digital output has to be synchronous to the internal clock. Therefore A/D INTERNAL is automatically activated and cannot be changed. User's Guide ADI-8 PRO © RME... -

So as long as you are working with the ADI-8 PRO - no problem. Working with de- vices of other manufacturers you may experience drop outs when the sample rate changes only slightly. User's Guide ADI-8 PRO © RME... -

16-bit media in some cases. In reality however, DC-free converters and limita- tions posed by real recording environments negate any advantages that dither might bring. Dither is most helpful at the end of the recording chain, at mastering down to 2 tracks and 16 bit. User's Guide ADI-8 PRO © RME... -
