Copy Mode - RME Audio ADI-8 PRO User Manual

9.3 Copy Mode

The function COPY MODE turns the ADI-8 PRO into an outstanding ADAT/TDIF and
TDIF/ADAT format converter, a digital patchbay, a signal distributor and a digital 16/24 bit con-
verter.
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. BIT SPLIT is still available (see below). The digital
input signal is also 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 simultaneous. This allows to convert a signal from ADAT optical to TDIF-1
or vice versa. Additional 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 BIT SPLIT isn't activated MAIN and AUX also operate simultaneous 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.
In Copy Mode both BIT SPLIT and COMBINE are available, so besides direct copy and format
conversion between ADAT optical and TDIF it is also possible to recombine a split signal while
copying, or split a not split signal, or recombine and split again into another format.
When BIT SPLIT is activated the distribution/copying within one format is not available, as
MAIN and AUX carry different data.
Emphasis
The TDIF interface and the DA-converters of the ADI-8 PRO support Emphasis. Please
note that an Emphasis indication will not be stored or processed on the sound when doing digi-
tal transfers between TDIF and ADAT, because the ADAT standard does not include Emphasis.
