Merge Channels - Bosch MADI Card Plus Series User Manual

Configuration

Merge Channels

A Merge is where an certain amount of MADI channels from one (1) MADI device is combined with a certain amount of
channels from another MADI device to build a total system of up to 64 channels. MADI channel mapping and merging
associates ADAM channels to MADI channels.
ADAM Channels - the channels are located on the ADAM frame.
MADI Channels - the channels are located on the MADI stream.
A merge can work on a Fiber or Coaxial connection. Use Figure 6 or Figure 7 on page 11, to wire your cards appropriately.
MADI Merge Example
FIGURE 25.
The example shown in Figure 25 shows two (2) MADI devices sending 8 channels each to one (1) MADI 16 Plus Card. The
audio path for the channels is as follows:
EXAMPLE: Device 1 sends eight (8) channels (MADI channels 1–8) to the MADI card (2). The MADI card sends
eight (8) more channels (MADI channels 9–16) to Device 3. Device 3 takes and replaces all 16
channels and sends those 16 channels to Device 1. When Device 1 receives the 16 MADI channels, it
takes its eight (8) channels (1–8) and replaces them with new data and passes the 16 channels to the
MADI card. When the MADI card receives the 16 channels from Device 1, it takes its channels
(9–16) and replaces them and sends them on to Device 3 which takes and replaces all 16 channels and
forwards it on. This continues as long as the data path is open.
IMPORTANT: It is critical to assign channels correctly in the MADI Channel Mapping window. For more information,
see "MADI Channel Mapping Window" on page 20.
