3025EMC Master Control Switching & Channel Branding
Revision 3.0.3 Page 75
Note that the RS422 level should NEVER be the same as the video and audio levels
as this will cause issues during a transition.
4.10.2. Primary Sources
This feature is to support panels in a multi-channel system. In a multi-channel system, some channels
may have specific sources that will be used. These are defined as primary sources. If a single panel is
configured to control the multi-channel system, when the panel selects the channel, its program and
preset busses will be configured to match the Primary sources configured here.
There are 32 primary sources that can be configured on the EMC.
4.10.3. Non-Quartz Upstream Routers
When the EMC controls non-Evertz routers, then these settings must be used. These settings are used
based on the protocol used by the EMC to communicate to the third party router or router control system.
Force Delay: This control will be greyed out if the upstream router is an Evertz router controlled over Q-
Link. If not checked, the EMC will wait for the router response OR the Switch Delay time
and complete the transition as soon as the first of these occurs. If ticked this forces the
Switch Delay to always be used before the EMC completes the transition.
Note: If required the Force Delay can be used for Evertz Routers. To enable, set any
control port other than Q-
Link2 as the Port Number, enable the Force Delay
checkbox then set the Port Number back to Q-Link2.
Interrogate Mode: For some upstream protocols it may be necessary to interrogate the preset and
program bus to make sure that any switch request has been carried out. This is the case when the
protocol does not issue unsolicited route updates, if so then this combo-box should select the
"interrogate route required" option.
4.10.4. Options
Disable Same Source Automation Cuts: For normal cuts the audio is faded to silence, then the
upstream router is switched, then the audio is faded up again. Also for mixes the audio
will mix between the sources. In both cases this can cause an undesirable dip in the audio
for same source automation cuts. If this is an issue with a particular automation system
then tick this box to disable same source automation cuts. This then causes the EMC to
check for a same source cut or mix and abort the transition if this is true.
4.10.5. Controlling an Upstream Router
The EMC can control an upstream router to increase the number of sources available to the PGM and
PST inputs. The EMC must be configured to control the upstream router and this involves several
separate settings:
1. Decide whether you will use a serial connection or Q-Link (Evertz routers only)
