Sound Level Meter Correction Value KSET The correction value page offers a measurement wizard for live event monitoring, applicable in case the measurement location differs from the loudest position in the live event area. Measurement Position The goal at live event monitoring is to measure the sound level at the loudest position accessible by the audience. Setting up any sound level measurement at this loudest location is typically not practical, thus an alternative measurement position is chosen. The recommended measurement position in order to minimize the influence that audience noise has on the measurement: • Mount the measurement microphone in front of the main speakers • Position the XL2-TA Analyzer at front of house (FOH) • Connect the XL2-TA Analyzer and measurement microphone using a professional audio cable Positioning the measurement microphone at front of house (FOH) may result in audience noise interfering with the measurement results. The audience noise will be further amplified by the measured k-values. Level Difference Prior to the start of the live event, the level difference between the loudest and the measurement position is measured. The XL2-TA Analyzer calculates the level difference automatically based on the individual sound level measurements at both locations. This level difference is included in the sound level reading during the live event, and the XL2-TA thereby displays and records the sound pressure level of the loudest point.
