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