Graph Speed Select

Graph speed select refers to the response speed of the Analyzer meters. It controls the peak and hold times as well as the decay rate of the meters. This is very useful when you are trying to identify quick transients and is probably most noticeable when you have selected either Peak Hold, Point, or Peak Difference.

To EQ (Live Application/Pre EQ Only)

The To EQ feature is designed to optimize your live sound by finding high and low spots in the room and then applying an automatic flattening curve to the signal. Additional tools needed to use this feature are a pink noise generator and a reference microphone setup in the room that is to be analyzed. As you generate pink noise through your house speakers, return the signal to the D8B via the reference microphone, selecting your reference point as you route signal through the RTA-31 (Pre- EQ). Pressing the To EQ button will take a snap shot of the analyzer’s current state and then send those settings to the EQ section, which will automatically compensate (flatten) the curve based on the input signal.

Note: You only have approximately four seconds to Undo the To EQ button before it is saved as the current Graphic EQ state.

Pre EQ

The Pre EQ button selects the analysis point (on the analysis graph) to occur prior to the EQ section.

Post EQ

The Post EQ button selects the analysis point (on the analysis graph) to occur after the EQ section.

Freeze

Freeze will freeze the Analyzer at the same instant that the button is pressed. The freeze frame can also be copied to the Graphic Equalizer by selecting the To EQ button.
