Why and when do we need presets?
Presets are a quick and efficient way to recall a known configuration of one or multiple DSP blocks. The process of creating presets is the same for Audia or Nexia software. A preset resides in the layout file (.dap or .nex) and can be recalled from the Audia/Nexia software, a daVinci panel or an external trigger (Select 8, contact closure or 3rd party controller).
Presets DSP blocks
Two types of preset blocks are available to the designer:
- Preset button blockUse a preset button to recall the preset from Audia/Nexia software, a daVinci panel or a third party controller.
Below is an example of a preset button block with two presets assigned
(NOTE: a preset button is not required if recalling presets via RS-232/Telnet).
- Remote Preset blockUse a remote preset block if the recall of the preset should be triggered from a logic signal. The preset will be recalled for every 0 to 1(low to high) transition on the logic input.
Below is an example of 4x normally closed momentary switches connected to the logic inputs of a Voltage Control Box (VCB) (NOTE: blue highlighted text indicates the last recalled preset).
Recall presets from a daVinci panel
You can recall a preset from a daVinci panel by using a button control with the DSP block type set to Preset in the data attribute tab of the property sheet. You can create a visual indication of the last recalled preset by using an LED control set to Preset in the data attributes tab of the property sheet.
Recall presets from 3rd party controller
Recalling a preset from a third party controller via RS-232/Telnet is very straightforward. Below is a template ATP/NTP string:
RECALL 0 PRESET 1002
This command will recall preset 1002 (where 1002 is the preset ID #). Please note that the device number will always be 0 since presets apply to the entire system.
We also have a Command String Calculator tool available to help with additional command string programming. More information about presets, including a step-by-step guide for creatings presets and advanced preset programming tips, can be found in our archived newsletter. The companion .dap file is also available for download. Happy programming!
