Revision MM2006-1 X16 MADI Merge Unit
3.4 Configuring the X16
3.4.1 Power On
Power on the X16 using the main power switch located on the rear
panel adjacent to the IEC connector. The front panel Power LED will
illuminate once power is received to the unit.
NOTE: A set power-on sequence is not required for the X16 to
operate properly.
3.4.2 MADI Mode
Before the X16 can properly merge audio data, it is important to con-
figure it correctly to meet the configurations of the transmitting audio
devices.
NOTE: If the MADI configuration of the transmitting devices dif-
fer to the that of the X16 then the X16 will not merge audio data.
■ Select the sampling rate. Press the Sample Rate switch to
select either 48kHz, or 96kHz operation. LED indication is pro-
vided to confirm selection.
■ Select the MADI format. Press the MADI Mode switch to select
either Standard (Std) or Extended (Ext) MADI format. LED indi-
cation is provided to confirm selection.
The Standard MADI protocol follows the origins of the format and ca-
ters for 56 audio channels at 48kHz. The more recent Extended
MADI format allows for 64 channels to be streamed down one cable
at 48kHz sampling. When operating at the higher sampling frequen-
cy of 96kHz, the available channel count is effectively halved, there-
fore providing 28 channels in Standard MADI mode and 32 channels
when operating in Extended MADI mode. You will be able to confirm
the number of available channels by looking at the Audio Channels
Out section.
■ Audio Channels Out. This section provides visual confirmation
of the number of channels that the X16 is configured to work
with. One of the four LEDs will illuminate to confirm channel
operating conditions. These are: 28; 32; 56 and 64 channels.
■ Select the Processing Mode. Press the Processing Mode
switch to select either Merge or Thru. LED indication is provided
to confirm selection.
Merge configures the X16 to Merge the first 16 channels of each
connected MADI input together. See
3.5 X16 MADI Merge Operation
for further details.
Thru configures the X16 to pass up to four complete MADI streams
directly to a four pairs of output connectors (one SC and one BNC)
without affecting the MADI stream itself. See
3.5.3 MADI Thru Mode
for further details.
