First usage 5.1 quick start the user interface of the adi-8 dd is characterized by a clearly structured architecture and an unambiguous labelling of the front and rear sides. The device can thus be used easily without a manual, because numerous leds show the state of...

User's guide adi-8 dd © rme 7 5.2 the dd plain and simple with a device as powerful as the adi-8 dd, it is for sure sometimes difficult to find out what's going on, or can be done with it. The device is capable of 34 different format conversions – which nobody can remember. And how are they set up? ...

User's guide adi-8 dd © rme 9 6. The aes to adat/tdif converter 6.1 general this adi-8 dd's functional unit, which will be called 'left part' further on, is an 8-channel format converter from aes, tdif or adat to adat/tdif, with the output signal being transmitted both at the adat and tdif ports in ...

However a miss- ing or invalid input signal is indicated by slow flashing of the source led. As soon as a valid input signal is present the four sync leds will react per ...

User's guide adi-8 dd © rme 11 6.5 outputs adat optical/tdif the adi-8 dd provides two digital outputs, both in adat optical and tdif-1 format. In normal operation only the main outputs are used. When using more than the first 4 channels at acti- vated ds (double speed), the aux outputs also have to...

User's guide adi-8 dd © rme 13 7. The adat/tdif to aes/ebu converter 7.1 general this adi-8 dd's functional unit, called 'right part' further on, is an 8-channel format converter from adat/tdif or aes to aes/ebu. Because the double wire and sample split (s/mux) formats don't contain a coding, the ad...

User's guide adi-8 dd © rme 15 7.4 outputs aes/ebu at the rear side of the adi-8 dd there are four xlr sockets for the aes/ebu outputs. Every output is transformer-balanced, ground-free and compatible to all devices with aes/ebu port. Connection is accomplished using balanced cables with xlr plugs. ...

If a digital signal is applied to an input, the re- ceiver has to synchronize to the carrier clock in order to read the data correctly. To achieve this, the receiver uses a pll (phase ...

User's guide adi-8 dd © rme 21 the tdif format is especially critical with respect to word clock. We have mentioned this in different places of this manual: when the adi-8 dd is slave no additional word clock connection is necessary. In case da88 and/or da38 are slave the word clock output of the ad...
