IN/OUT Level Meters
The IN and OUT level meters are located next to the response graph. They display the levels of
the input and output in dBu, dBFS or dBV. When the levels go into the red, the unit is near clipping.
This is a useful tool for observing gain loss due to equalization settings. To compensate, you can use
the OUTPUT slider located on the Equalizer Control window.
To activate the IN/OUT level meters:
1. Click on Options in the main menu bar.
2. Click on Meters option. A window will appear which will allow you to choose whether the
level meter will be calibrated in dBu, dBFS or dBV. Click on the appropriate mode and
click OK.
3. When the Display Level Meters option is active, a check will appear next to the Display
Level Meters in the Meter Options dialog.
4. The IN/OUT meters may also be activated by clicking on the inactive, grayed-out meter.
NOTE: While the IN/OUT level meters are running, the DATA indicator on the
DFR11EQ unit will continually flicker. This is normal operation while the IN/OUT
meters are active.
OUTPUT Control
The OUTPUT control slider is located on the right side of the Equalizer Control window, in both
the Graphic and Parametric mode. Raising or lowering this slider will raise or lower the gain of the
output. As the output level is adjusted, the Response Curve Viewer will adjust accordingly, moving
the current response curve to the new level on the graph. If you take a snapshot before adjusting the
output level, the snapshot will remain at the original output level. The IN/OUT meter will also adjust if it
is active.
To adjust the output gain, drag the OUTPUT slider, or click on the appropriate value on the slider.
The output slider may be used to adjust the output level if the sound processing has lowered the gain
of the signal to an unacceptable level.
Reversing the Output Signal Polarity
This option is designed for sound systems where there is a component which inverts the polarity
of the signal, bringing it out of phase with the rest of the equipment. Inverted polarity can cause phase
cancellations in the audio. Using this option of the DFR11EQ software, you can digitally invert the
audio signal in order to compensate. This will save the time and expense spent in wiring customized
cables. When the polarity is reversed, OUTPUT POLARITY REVERSED appears on the main
window.
To use the DFR11EQ as an audio signal polarity inverter:
1. Click on Options in the main menu bar.
2. Click on Reverse Output Polarity. A check will appear next to this option to indicate that
it is active.
