Tips, tricks & things worth knowing
Dolby AC3 and DTS
*The digital interfaces of the PHASE 22 system can also be used independently of the
S/PDIF standard (see also page Ü 37 Digital-Out at "NonAudio"). Various manufacturers
of software DVD players support playback of DVD studio material over the PHASE series
of TerraTec Producer. Signals in Dolby AC3 or DTS format can therefore also be trans-
ferred using the digital interfaces.
Always with the beat - digital synchronization
When recording with the digital interface, make sure that the sampling frequency (rate) of
the card matches that of the device from which you are recording. To ensure correct syn-
chronization of the devices, you must switch the MasterClock to "External" in the PHASE
Control Panel (see also page Ü 36).
If you forget this step, audible errors such as dropouts and clicks may occur during re-
cording - and already when monitoring the signal. And also in the reverse situation (an
external device should run at the same rate at the audio system), make sure that settings
of your additional peripherals match. The PHASE Control Panel must be set to "Internal"
in this case (such as during operation without externally connected digital devices). If the
devices are to be permanently connected to one another in both directions, you must de-
cide which device will provide the clock signal.
The digital interface of the PHASE 22 audio system transfers all bit resolutions between 8
and 24 bits and all sampling rates between 8 and 96 kHz (Digital Out at up to 192 kHz).
Please note that not all devices can process sample rates higher than 48 kHz. To transfer
a signal recorded at 96 kHz to a DAT recorder, it's necessary to use suitable software to
convert the file(s) to 44.1 kHz or 48 kHz first.
