9.3 Copy Mode
The function COPY MODE turns the ADI-8 DS into an outstanding ADAT to TDIF and TDIF to ADAT format converter, a digital patchbay, a signal distributor and a digital 16/24 bit converter. When COPY MODE is active the digital input signal of the DA-converter is routed directly to the digital outputs of the AD-converter. The AD-converter can't be used anymore. That's why the complete AD clock section will also be disabled. All LEDs of the AD-section (INPUT LEVEL, OK, OVR, INPUT, EXT., INT.) will be off. PROCESS is still available (see below). As usual the digital input signal is available at the analog outputs for monitoring purposes. In COPY MODE the digital input is set by the key DIGITAL INPUT, the output signal shows up at ADAT out and TDIF simultaneously. This allows to convert a signal from ADAT optical to TDIF-1 or vice versa. Additionally it is possible to copy the input signal directly to a device of the same format, without the need of changing connectors or cables. As long as PROCESS BS or DS isn't activated MAIN and AUX ports also operate simultaneously and carry the same audio data. With this it is possible to distribute the output signal to two devices of the same format. For example an ADAT optical signal can be distributed to 2 ADAT and 2 TDIF devices at the same time. In COPY MODE all extended functions (PROCESS BS/DS, COMBINE BS/DS, DITHER) are available, so besides direct copying and format conversion between ADAT optical and TDIF it is also possible to re-combine a split signal while copying, or split a not split signal, or recombine and split again into another format. When Bit Split or Double Speed is activated the distribution/copying within one format is not available, as MAIN and AUX carry different data. Please note the Block Diagram on page 21. It shows the complete signal path within the ADI8 DS, in an easy to understand way, also in activated COPY MODE.

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