192 kHz 8-Channel.
The ADI-192 DD is the successor to the highly successful ADI-8 DD. The completely re-engineered device was designed to be the most powerful format and sample rate converter ever. Hence the ADI-192 DD not only features considerable improvements compared to the ADI-8 DD, but also adds a number of new and unique features:
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 schematic view. Thanks to free selection of inputs, signals can be copied and distributed between all connected devices - without the need to change any cables. 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.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 24/192kHz sample rate converters allow 8-Channel sample rate conversion and clock decoupling of the highest quality.
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.
RMEs SteadyClock(TM) 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.
