Comprehensive sound level measuring
logging for Q-SYS™

SPL Logger Logo - Forward Thinking Designs

SPL Logger is an audio loudness monitoring and logging plugin for QSC® Q-SYS™ DSP systems. Simplify your adherence to occupational safety and health rules as well as organizational policy. Providing real-time and historical loudness data, SPL Logger will make it easier than ever to keep your shows to a safe volume.

SPL Logger is indispensable for theaters, amusement parks, live shows, bars, and restaurants.

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.

SPL Logger UCI Configuration - Forward Thinking Designs

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.
