The MPX generator control allows you choose from several key test tones. o Square is a 60Hz square wave useful for visualizing tilt. o Quick Sweep is a very fast 1,000 – 60,000Hz sweep with a click before each sweep, designed to offer a visual reference as to the high frequency performance of your STL or exciter. If you were to connect an oscilloscope to a calibrated tuner with MPX output (such as the Belar Wizard, for example) this is the shape you would see if your STL or exciter had a flat high frequency response. Any deviation from a flat high frequency response means a loss of loudness and/or stereo separation. o 400Hz is a full amplitude sine wave to allow you to set an exact 75kHz deviation with a mod monitor. o 0.5 – 5.0 and 0.5 – 30.0 are subsonic sweeps that allow you to see the extreme low frequency response of your air chain. o 31,187.6Hz, 13,586.7Hz, and 8,667.4Hz sine waves – the “Bessel Null” tones – allow you to set exact +/-‐ 75kHz modulation with a direct off-‐air spectrum analyzer. Display Settings Menu The Display Settings Menu allows you to customize what is displayed in up to 8 different windows on-‐screen at the same time. Each of the 8 Display buttons allows you to choose which processing parameters or visualizations from one of Omnia.9’s valuable built-‐in diagnostic tools are viewable in each window. The 7 main groups are Undo Meters, Processing Meters, Input Meters, Loudness Meters, Oscilloscope, RTA, and FFT Spectrum Analyzer. You can also turn off any or all of Omnia.9’s displays here – a handy feature for keeping your processing meters and settings from curious eyes! Since Omnia.9 can display such a wide variety of information about your station’s audio processing and signal, it allows you to create and save up to six Display Presets, which are always visible in the 52
