3.7 – Configuring the Logic Inputs
In Control Center, select the DialogBox, open the device setup form and select the Logic Inputs tab to see the screen
show in Figure 12. This tab also shows the revision level of both the on-board processor software and the CobraNet
firmware.
Figure 12 - Logic Input Tab
Each input can be configured as a mute function, a volume function or a source select function. Each function can only
be allocated to a single input and an input can only carry out a single function. The state of each logic input is also
shown on this tab. The state LED will turn green when the input is active.
3.7.1 – Mute Inputs
An input configured as a mute can input a single local input or one of the zone outputs. While the input is not active,
the specific audio will pass unabated. When the input is activated, audio on the specified channel will be muted.
As well as the input status, there is an indictor on each local input and each zone output to show if the mute has been
activated.
3.7.2 – Volume Controls
The volume can be controlled at two points in the output zone signal flow. The first is what we call the pre-ducker
volume which is after the EQ. limiter, and gain sections right before the ducker. The second is right at the output after
the ducker and source select. Each input can be set to control either volume up or volume down at either of the two
points. The current level of both volume points are indicated on each output zone.
There are two ways to operate a volume control input. If an input configured as a volume control is turned on then
quickly off again (as produced by the press and release of a push button) the associated volume will increment or
decrement a single step. Alternately, if the input is turned on and held on for at least two seconds, the volume will
begin to auto-increment or auto-decrement until the input is turned off or the maximum or minimum volume is
reached.
