To change the frame pattern of both MADI outputs on the device:
1. Go to one of the
MADI
tabs in the
OUTPUT
section.
2. Toggle the switch for 96k to use the 96k frame at 88.2 kHz and 96 kHz.
To change the frame pattern of both MADI outputs using the web remote:
1. Open either MADI output port in the routing view.
2. Select the frame format from the corresponding menu.
The 96k frame setting affects outgoing MADI signals at sample rates 88.2 kHz and 96 kHz.
At other sample rates, the setting is not relevant and does not affect the outgoing signal.
It is not possible to select separate settings for each MADI port. Both ports will be affected
regardless which output tab is used to change the setting.
9.3.2. MADI Daisy Chains
MADI is a uni-directional protocol with a fixed number of channels. When more than two MADI devices
are connected, a serial connection is required. This is also referred to as a "daisy chain". The output of
the first device is connected to the input of the second device, the output of the second device to the
input of third device, and so on, until the signal is plugged into the input of the first device.
In a daisy chain, each device must be configured to pass on the
relevant
audio channels of its MADI input
(the preceding devices) to the MADI output (the following device). Otherwise, each device would create a
new MADI signal and not pass on audio from the devices that are connected to it.
While many RME devices pass on MADI signals automatically, the 12Mic-D must be
explicitly configured to do so.
In order to pass on signals, configure the output routing of the required output port to pass on the signal
from the MADI input port.
The latency of the MADI I/O is four samples.
9.3.3. MADI Port Mirroring
A redundant MADI connection protects from loss of audio in case of a single cable failure. To achieve
redundancy, the receiver must support MADI redundancy. The sender must send two identical MADI
signals on two outputs, usually the coaxial and optical ports.
The 12Mic-D features independent routing for both MADI output ports. For this reason, a "mirroring" of
the signal must be manually created. In order to do this, the routing of the two MADI outputs should be
configured to contain the same routing.
The receiving device usually ignores the audio contents of the two MADI signals. Therefore,
the redundancy may appear to be set up even though the 12Mic-D sends different audio
signals on both ports. Always ensure that the routing is correct for both output ports.
