7.5.3 Routing and input signal display
The four bargraph displays can also give information about the routing implemented between the input and output
channel in the current preset and the input signal level. This information is accessed by pressing and holding either the
IN A or IN B tab.
As an example (see Figure 25), pressing and holding the IN A tab illuminates the “LOAD” LEDs of OUT 1 and OUT 2:
this indicates that the IN A input is routed to OUT 1 & 2 output channels. At the same time the “SIGNAL” and “-25dB”
LEDs of the OUT1 bargraph display are lit showing the level of the signal delivered at the A input of the controller.
Note: The SIGNAL LED lit when the input voltage reaches 10 mV and the CLIP LED lit when the input voltage reaches
9.8 V (22 dBu).
Figure 25: IN A input channel routing and level information
In the same way, as shown in Figure 26, pressing and holding the IN B tab illuminates the “LOAD” LEDs of OUT 3 and
OUT 4: this indicates that the IN B input is routed to OUT 3 & 4 output channel. At the same time the “SIGNAL” and
“-25dB” LEDs of the OUT2 bargraph display are lit showing the level of the signal delivered at the B input of the
controller.

Note: Rotating the encoder wheel while pressing and holding either the IN A or IN B tab allows to set the input gain of
the concerned input as described in section 7.1.2.
