NTI REPRESENTATIVE: What we are showing today is a prototype of the Digirator DR2, our first digital audio generator. It is the counterpart for our analyzer, Digilyzer DL1, which is able to analyze digital audio signals. AES, three signals: SPDIF, optical signals, and also ADAT signals.

The Digirator has an AES3 output, SPDIF output, and always an optical output for stereo or ADAT, 8-channel ADAT signals, very important for professional environments is that the generatora can be synchronized to any studio clock or video clock. For this, we have an input on the upper side of the unit, accepting video broadcast signals in PAL or NTSC format, as well as word clock signals and AES3 or [INDISCERNIBLE] reference signals.

It can generate signals from 44.1 kHz up to 192 kHz for professional and consumer frame standards. Like on the other generators, we have a rich set of signal forms it can generate on the Digirator DR2. A unique feature is the generation or the playback of Dolby and DTS bitstreams, so if you work in a multichannel environment you can play back Dolby in many different formats like Dolby D, Dolby Plus, Dolby E or different DTS standards.

The channel status, which is important for digital audio transmissions, can be set here from pro to consumer standard. Non-linear PCM, the emphasis can be manipulated and also the ADAT bit. It can be chosen if ADAT or a two-channel signal is generated by the optical output.

For nonlinear PCM signals, it is important that data streams are transmitted transparent and true to transmission systems or true to units. For this we have implemented a transparency check function showing if the outcoming signal is transparent or coming back to the incoming signal.

We here send out a sequence of a special signal, and on the other side we analyze how many bits comes through the system or come to the system which are not manipulated. If all the 24 bits of the bitstreams come in, this signal would be -- this transmission line would be suitable for Dolby D, Dolby E, and Dolby DTS signals, so nearly every multichannel format.

Also important in broadcasting environments is the measurement of the delay of an audio signal, so the delay a signal needs from the output back to the input. We display this in frames, NTSC or PAL standard, and also in milliseconds.

The Digirator DR2 is shown here as a prototype and will be available on the market in the fourth quarter of this year. Thank you very much.
