SoundSystem DMX 37

The Digital Input.
The digital input accepts a standard S/PDIF signal from consumer
devices. This falls into the category of MiniDisks or DAT recorders, for
example. When recording there are few important steps you need to
take into account and they are described in the following.
The Basics
The digital module that comes with this card should be used to connect digital output devices
(S/PDIF standard) to the SoundSystem DMX. For recording, you can use either a coaxial (RCA)
or an optical (also often known as a TOS link) input.
RCA IN
TOS LINK IN
Two devices can be connected at the same time, however, only one can be used at a time to
record.
The DMX digital interface operates with all three standard frequencies at 16-bit resolution (32,
44.1, and 48kHz).
On the SoundSystem ControlPanel select the input source (coaxial or optical) under
"Settings". Then select the setting "Input" as DIG(ital) MODE. This tells the SoundSystem to
automatically synchronize itself to an external digital signal. This is necessary in order to
guarantee error-free ("drop out"-free) recordings.
For playback purposes, the volume control for the digital signal is labeled DIG IN. Notice that
this controller only affects the playback volume of the signal connected to the digital input –
the digital recording via the source "DIG" is not affected by it.
For digital recording. You have two options for recording digital input. The first is to record
the DMX's entire signal, i.e., everything that was stored in the Mixer up until the time of
recording - including residual noise e.g., from a CD ROM drive.
The second is to only record the specific digital signal itself – this will probably be the
preferred alternative for most applications. Select the desired recording source on the
ControlPanel on the page "Record" (Mix and DIG).
By the way: Any copy protection that is present (SCMS or CopyProtection bit) will be ignored
and not recorded.
