M-480, M-400: How to Setup an M-480 as FOH and an M-400 as a Broadcasting/Monitor Mixer

The following article will guide through setting up an M-480 for FOH and an M-400 as a Broadcast or Monitor mixer--receiving audio from the FOH M-480.

The example below will use the FOH M-480's SPLIT/BACKUP port connected to the broadcast M-400's REAC A port. 
Note: The M-480's SPLIT/BACKUP port duplicates it's REAC A output network.

REAC CONNECTION
Connect the M-480 SPLIT/BACKUP port to the M-400's REAC A port.

FOH M-480 SETTINGS

1. Press the SYSTEM button and set the INTERNAL SAMPLING FREQ to a desired sample rate.
2. Press F2 (REAC CONFIG) and then press F1 (SETUP).
3. Move the cursor to the REAC SETUP section, select FOH (DEFAULT) and then press ENTER.

BROADCAST/MONITOR M-400 SETTINGS

1. Press the SYSTEM button and set the INTERNAL SAMPLING FREQ to match the FOH M-480.
2. Press F2 (REAC CONFIG) and then press F1 (SETUP).
3. Move the cursor to the REAC SETUP section, select MONITOR/BROADCAST A and then press ENTER.

ASSIGNING CHANNELS

Now that the consoles are setup, the FOH M-480's input channel DIRECT OUTs can be used to patch out to its REAC A outputs. These will be "seen" as inputs on the Broadcast/Monitor M-400. 
For example, if the FOH M-480's input channel's direct out is patched to its REAC A outut 32, this will be received and "seen" from the Broadcast/Monitor M-400 as REAC A input 32.

FOH M-480

1. Press the PATCHBAY button.
2. Press F2 (OUTPUT) and then F3 (REAC A).
3. Press the down arrow to scroll down until the input channels appear on the left (e.g. CH 1, CH 2, etc). These are the Direct Outs of the input channels.
4. Cursor to a desired REAC A output for a channel and then press ENTER. An arrow will appear in the box indicating the channel's direct out is patched to the REAC A output above.
   After patching all channels is completed, each input channel's direct out point needs to be set:
5. Press the SEL button for each input channel and then set the DIRECT OUT on the screen to PRE EQ.
   
6. Repeat this for each input channel.

BROADCAST/MONITOR M-400

1. In the setup section of the top panel, press the PATCHBAY button.
2. Press F1 (INPUT) and then F3 (REAC A).
3. Patch the REAC A inputs on the top of the grid to the desired M-400 channels on the left. As a reminder, the Broadcast M-400's REAC A inputs on the top of the grid are sourced from the FOH M-480's SPLIT/BACKUP port.
