RME ADI-192 DD

The unit consists of three 8-channel format converters with 24 bit audio resolution. The three output formats ADAT, TDIF and AES independently access the three input formats ADAT, TDIF and AES. Thanks to free selection of inputs, signals can be copied and distributed between all connected devices - without the need to change any cables. Four XLR AES/EBU inputs and outputs each, and two ADAT and TDIF inputs and outputs allow full 8-channel operation even at 96 kHz / 24 bit. At 192 kHz, there are eight AES channels and four ADAT and TDIF channels. Switchable 24/192 kHz sample rate converters allow 8-channel sample rate conversion and clock decoupling of the highest quality. 

Due to the unlimited input selection, the unit not only transfers data to the same output format. For example it can be operated as quad AES/EBU sample rate converter.

Applications include:

AES/EBU frontend for RME's digital I/O-cards (with ADAT optical I/O) 

TDIF frontend for RME's digital I/O-cards (with ADAT optical I/O) 

AES and ADAT frontend for DTRS machines 

8-channel AES, TDIF and ADAT input and output for digital mixers with ADAT/TDIF port 

Operation of four SPDIF or AES devices with different sample rates in any digital audio network 

Converts Double and Quad Wire to Single Wire and vice versa, even with simultaneous sample rate conversion 

48 LEDs clearly display the current status of the incoming and outgoing signals and the processing performed within the unit. The SyncCheck technology known from other RME devices indicates whether the input signal is locked and whether all inputs are sychronized. The AES output signal can be given a consumer or professional status. The first AES output (channels 1/2) is also available as optical TOSLINK.

Professionals will love the fact that the ADI-192 DD supports Double Wire, Quad Wire, S/MUX and S/MUX4, making it compatible to all methods of increasing sample rates by sample multiplexing on all platforms. The unit can also convert between these formats, even along with SRC. If more than 8 channels are required, several units can be cascaded and synchronized sample-accurately by word clock.

The ADI-192 DD also features an automatic distribution mode. If only one of the four AES inputs is used, the device will copy these two channels to the other three AES outputs.

RME's SteadyClock™ guarantees excellent clock quality in every situation. Due to the highly efficient jitter reduction, any clock signal can be improved and refreshed, and subsequently be used as reference clock at the word clock output. Intelligent Clock Control (ICC) will retain the last valid sample frequency in case of a loss of the input signal. All settings are retained when the device is switched off.

CONCLUSION

The ADI-192 DD is the all-in-one solution for every application of format and sample rate conversion, from 2 to 8 channels. Its flexibility is unsurpassed and the price/performance ratio is simply sensational.
