CHAPTER 3: Key Audio Design Features Toggle Events Toggle events both look and behave like checkboxes - they are either on or off, active or inactive. Any or all toggles (checkboxes with links) within Halogen can be linked to a toggle event. This includes: l Toggle preset Active checkbox l Toggle checkbox on a DR2, DR3, DR6, Web Control page or 3rd-pary control screen l Relay output on a HAL1x or HAL2 l Logic output on an EXP3x or DR4 l Mute control link found on Input, Output and many other Level blocks elsewhere l Paging Station input Talk buttons on the Paging Station & Pager1 blocks l Input or output mute on Auto mixers or matrix mixers (regular or Gain-sharing) l Cross point Enable checkbox on a mixer or matrix mixer l Cross point Priority enable on a Gain-sharing mixer or matrix mixer l Paging or Emergency zone active indicator (Paging Manager or Paging Zone block) l Room combine or conference room combine "movable" wall - use time to combine a room or virtual room (e.g., overflow). l Off @ Min on every linkable Level block or cross point l Force duck (Ducker block) l Ramp pink noise up or ramp pink noise down controls on the Pink Noise: Ramped block, for noise masking applications l Audio active or inactive above a user-defined threshold in the Voice Detect block l Audio cross point enables between rooms/destinations in the Conference Switchboard block l The AEC's Ambient Noise Reduction, or for testing-only, the AEC Enable in the AEC block Command Events Command events have a start time, but no end time. They simply activate at the configured time, and that is all. You can either think of command events as completely independent, autonomous and unique events that do their own thing on their own time. Or mentally think of them as a group of actions that follow or stack upon each other. Any command in Halogen can be linked to a command event, including: l Command preset Assert l Command button on a DR2, DR3, DR6, Web Control page or 3rd-party control screen Selector Events Selector events always have an active and an inactive state with a corresponding start time (Active) and end time (Inactive). They are always presented as a 2-position selector and therefore can only link to other selectors that are either already 2-positions, or once linked, will become and always remain 2-position selectors. Since selector events are always displayed and presented as 2-position selectors they always display a unique name for their two states or switch positions; they have two radio buttons labels. Selector vs Toggle Events Unlike single text label toggle events, selector events offer end users insight to two unique event states, not just on or off as toggles offer. Thus, selector events are useful when your school cafeteria is also the band rehearsal room where two event labels display "Lunch" and "Band" modes. Both labels would be visible, but only one at a time is active. For this application, the Event Manager is configured to change between these two event states and linking the event Active to a web page or DR6 would allow end users to view or 151
