Rta Menu - Omnia .9 Installation & User Manual

FM MENU DISPLAY SETTINGS

RTA Menu

The Real-Time Analyzer menu allows you to monitor many of the same sources as those mentioned in the Oscilloscope menu
section. The horizontal scale along the bottom of the RTA screen shows frequencies from 20 to 20,000Hz. The vertical scale
along the left side shows the amplitude of the audio in decibels.
The Delay control works the same here as it does previous and subsequent display sections.
♦
The RTA Resolution control lets you choose between a 1/3 and 1/6 octave display.
♦
The Averages control can be used to slow down or speed up the RTA's display response. A lower average setting (faster
♦
meter response) might be more useful for peak monitoring; while a higher average setting (slower meter response)
might be more useful for calibrating speakers. Higher averages are also useful for adjusting lower frequencies. The
recommended setting for speaker calibration is 100. Regardless of how the Averages control is set, the RTA
maintains a history "buffer" of 1,000 frames. Advancing the control to 1,000 will immediately display the average of
the last 1,000 frames.
The Target control moves the dark red target window and/or the amplitude scale up and down within the display, a useful
♦
tool for establishing a target when performing speaker calibration.
The Range control allows you to view a broader or narrower range of audio, indicated by the range scale along the left side
♦
of the display.
The Target Range adjusts the height of the target window within a 6dB range in half-decibel increments. Lower settings
♦
are better suited to more precise measurements. Moving the Target Range slider all the way to the left hides the
target window.
