logging for Q-SYS™

Features
Measurements
Calibration procedure built in to the plugin (requires microphone and calibrator, not included).
Linear, A, and C weighting filter options (ANSI S1.42 A and S1.42 C)
-
SPL, Leq 1, and Leq 10 - all the measurements you need to provide a safe environment
-
Leq is the equivalent continuous sound level over a period. You can think of it like an average. SPL Logger provides the equivalent continuous sound level for the last 1 and 10 minutes.
-
Graphing
-
Graph the current SPL, Leq 1, and Leq 10 measurements to keep your show right in the sweet spot
-
Each measurement can be turned on independently, and the view scale can be customized
-
Place the graph on your UCI for easy viewing, and customize the colors for use in a dark theater or outdoor festival
-
Set a timer to disable the graph display, or turn off the timeout for constant display
Log Files
-
SPL Logger logs your loudness data to a CSV file so you can review the data at any point in time. Data points are written once per second.
-
3 different logging modes are offered:
-
Manual mode: Manually enable logging at the start of your event or use the scheduler built in to Q-SYS™ to determine when to log
-
Threshold mode: Set a minimum threshold, and when the sound reaches that level, the plugin begins logging. No need to log loudness overnight when the venue is inactive.
-
Continuous mode: 24/7 SPL logging.
-
-
Automatic log maintenance: Configure logs to be automatically deleted after a set period of time, from 1 to 365 days
Limit Thresholds
-
Set maximum limits for SPL, Leq 1, and Leq 10 and get visual feedback when the limit is exceeded. Depending on your needs, these control pins can be tied to a warning light, email notification, or even additional Q-SYS programming.
