This window is used to configure the amplifier with Channel Names, Descriptions, Channel Types, Page Active Relay (PAR) functionality, Elements, ANC and Zone Assignments. The main window is divided into the General and Assignment sections.
Settings for the amplifier configuration can be entered here. If failover mode has been selected this area will update dynamically to show the settings that can be changed.
Name and Description
A Name and Description can be given to each of the amplifier channels.
Type
Each channel of the amplifier is represented as an individual Channel by default. By using the Type dropdown boxes beside each channel a channel can be set to take part in a Group or MultiWay. A Group would be used if the system designer needs to output the same audio through multiple channels. A MultiWay can be used to split Low, Mid or High elements through the use of a MultiWay Crossover.
If a Multiway is selected the Element Column will allow selection of which speaker module is being used.
The settings of the Type Column will dynamically adjust the Zone Selection options of other screens.
Output
Two selections are available. The options are 70V or 100V operation on a per-channel basis.
Page Active Relay Priority
The Page Active Relay Priority (PAR) spin control is provided so that a priority level that will activate the PAR on the rear of the device can be set. Any Paging events, including both regular and Emergency events, made to the output channel at the specified priority level or above will activate that relay for the specified channel. Selecting none will render the applicable PAR channel inactive.
This field is used to assign ANC-1s, Zones and Emergency Zones to each of the amplifier channels. The settings here will dynamically adjust dependant on the Type selection in the General section.
A Zone or Emergency Zone must have been created in the World Properties window first for it to appear in the Zone dropdown list.
A Unicast CobraNet bundle is able to be sent to each discrete channel of the amplifier without having an impact on the number of Simultaneous Pages in the World. This allows each amplifier to be fed with a discrete channel of audio from either Audia, Tesira or a multi-unicast / unicast transmitting device. A CobraNet Bundle number will be automatically allocated for the device and will operate as a regular BGM Source (the lowest priority in a Vocia system).
If two or more channels are configured in the software as a group or multi-way, the CobraNet Input with the lowest CN channel number will be used. For instance, if a VA-4300CV is deployed with channels 2, 3 and 4 configured as a group (or 3-way multi-way), the bundle and channel number assigned to Channel 2 will be presented to outputs 2, 3 and 4.
See the CobraNet Inputs and Outputs Overview section for more details on implementing CobraNet Inputs.
