Sample Rate Selection Menu
When the card is set as a
Master
Soundscape device and the Internal clock
setting is selected, this menu allows a sample rate to be selected. The
available sample rates are 44100Hz, 48000Hz, 88200Hz, 96000Hz,
176400Hz and 192000Hz.
In all other cases, the Sample Rate menu is greyed-out and cannot be
used.
Format Settings
MADI Standard SMUX
When the MADI standard SMUX box is checked and the card is operating
at high sample rates (88200Hz or higher), the data for each audio channel
is transmitted or received over two or four channels of the MADI interface
(ie., two at 88200 or 96000Hz, four at 176400 or 192000Hz). The number
of available channels is divided by two or four accordingly at these sample
rates.
When the MADI standard SMUX box is not checked, if operating at high sample rates (88200Hz or higher), the frame rate
is multiplied by two or four and the frame size divided by two or four. The same restrictions to the number of channels
apply as in SMUX mode.
For MadiXtreme 128 these settings apply to both MADI ports – they can not be set independently. For either card, please
ensure MadiXtreme is set to the same mode as the external device(s) connected to its MADI port(s).
MADI 56-Channel Mode
When the MADI 56-channel mode box is checked, the MADI interface can
transmit or receive up to 56 audio channels (reducing to 28 channels when
operating at 88200 or 96000Hz and 14 channels when operating at 176400
or 192000Hz). When the MADI 56-channel mode box is not checked, the
MADI interface can transmit or receive up to 64 audio channels (reducing
to 32 channels when operating at 88200 or 96000Hz and 16 channels
when operating at 176400 or 192000Hz). For MadiXtreme 128 these settings apply to both MADI ports – they can not be
set independently.
Test Mode Selection (may not be present)
This selection is for diagnostic and test purposes and may not be present. If this option
is present, it should be left set
to Normal .
Status
In the Status section, the MADI-A and MADI-B input ports are shown as
locked or unlocked (MADI-B is applicable only to MadiXtreme 128).
A port is shown as locked if a valid MADI input signal is detected and
clock synchronization has been established. If a MADI input signal is detected but clock synchronization has not been
established, the displayed status alternates between Locked and Unlocked .
If no MADI input signal is detected, or if the MADI signal detected is not valid, the port will be shown as unlocked. The
later case might occur if 56-channel mode is selected for the MadiXtreme but the device connected to the port is set to
64-channel mode.
