Power User Tip: The alignment delay compensates for the cancellation or
reinforcement of low frequencies when the same frequencies are reproduced by two
sound sources that are set apart from one another, such as a center-fill speaker that
is reproducing the summed stereo signal in a front-of-house system. By using fine
output-delay adjustments on the center-fill speaker and carefully setting the level,
the entire system can be put in phase, creating a seamless transition so that the
audience can’t hear where either main speaker ends and the center-fill begins.
Limiter threshold. Controls the limiter threshold for your loudspeaker. Note: This is
not your loudspeaker’s protection limiter.
The Limiter control consists of five elements:
• On/Off switch. By default, the limiter is off. To
enable it click or tap the On/Off switch.
• Threshold readout. This displays the set limiter threshold. You can also manually
enter the threshold in decibels you wish to set by clicking or tapping in this field.
• Fader. This controls the threshold of the limiter. When the signal’s
amplitude (level) exceeds the threshold setting, the limiter will
engage. The threshold can be set from -28 to 0 dB.
• 0.5 dB increment/decrement buttons. Use these buttons to make fine
adjustments to the limiter threshold.
4.6.1 Eight-Band Parametric EQ (full-range only)
Each full-range loudspeaker is equipped with an eight-band parametric EQ
allowing you to compensate for room anomalies or create an aesthetic effect.
EQ On/Off. By default, the parametric EQ is disabled. To enable it, click or tap on this
button.
Power User Tip: You cannot make changes to the parametric EQ unless it is enabled.
Reset. To reset the parametric EQ to 0 dB, simply click or tap the Reset button. This
returns each band to 0 dB, so that no frequency band is boosted or attenuated, and
returns the Frequency and Q parameters to their default state.
You can adjust the parametric EQ by tapping or clicking on any of the
bands in the graph and using your finger or mouse to draw a curve.
When any band is selected, the three controls at the top of the parametric
EQ will switch to control that band’s frequency, gain, and Q. These
controls allow you to make fine adjustments to each band.
You can turn off an individual band by pressing the On/Off button next to the Gain
control or by clicking or tapping the band in the graph.
