AXI 016 • Setup Guide (Continued)
NOTE:
A secondary EXP device is a device that has been set as a Secondary Unit in DSP Configurator (see the
DMP 128 Plus User Guide for more information regarding primary and secondary EXP devices). DTP CrossPoint units
are set to secondary by default.

and increase in intensity from -60 dBFS (lowest intensity, signal presence indication) to -3 dBFS (full brightness). The
red clip LEDs light solid to indicate clipping when a signal exceeds -3 dBFS. The red clip LEDs stay lit for one second

Application and Signal Flow Diagrams
The following diagrams display the different signal flows when primary and secondary EXP-enabled devices are connected to the
AXI 016.
NOTE:
Daisy-chaining two or more AXI 016 units together is not supported.
Connecting a Primary Device to the EXP Input Port
The diagram below displays the AXI 016 signal flow when only a primary EXP device, such as the DMP 128 Plus, is connected to
the EXP INPUT port of the AXI 016.
•
All 16 Expansion output channels of the primary device are routed to the line outputs of the AXI 016 (see path A1 in figure 5).
•
Expansion output channel 1 of the primary device is routed to the AXI 016 line output 1, and so on.
