7.5.3 Routing and input signal display
The four bargraph displays can also provide information about the signal routing between input and output channels in
the current preset, and the input signal level. This information is accessed by pressing and holding either the IN A or IN
B key (only available when the main screen is displayed).
As an example (see Figure 25), pressing and holding the IN A key lits the OUT 1 and OUT 2 “LOAD” LEDs: this
indicates that the IN A input is routed to OUT 1 & 2 output channels. The “SIGNAL” and “-25dB” LEDs of the first
bargraph display lit simultaneously, displaying the level of the signal delivered at the A input of the controller.
Note: The SIGNAL LED lit if the input voltage reaches -37.8 dBu (10 mV) and the CLIP LED lit if the input voltage
reaches 22 dBu (9.8 V).

Similarly, as shown in
Figure 26, pressing and holding the IN B key lits the OUT 3 and OUT 4 output “LOAD” LEDs:
this indicates that the IN B input is routed to OUT 3 & 4 output channels. The “SIGNAL” and “-25dB” LEDs of the
OUT 2 bargraph display are simultaneously lit, displaying 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 key allows to set the input gain of
the corresponding input as described in section 7.1.2.
