Power User Tip: Bring back the level on the GEQ slider to the point just before feedback,
so you don’t take out too much of that frequency content and sacrifice overall timbre.
Because the speaker is pointed at the mic, stage-monitor feedback typically occurs
in the higher frequencies, which also is where intelligibility comes from. Maximizing
your intelligibility and gain structure results in clearer-sounding monitors.
You can apply this process to the Main system, as well.
This is especially useful with applications requiring lavalier
or podium mics. These types of microphones are typically
omnidirectional condensers and are very prone to feedback.
In a main system, feedback is typically in the mid to low range. The
frequencies that are regenerating and creating a feedback loop
are those frequencies that are wrapping around the main system
due to the loss of directional control of lower frequencies.
When you are ringing out a system, and more than two or
three feedback loops are happening simultaneously, you have
reached the level where stability can no longer be achieved.
Try bringing down the overall output level or find a physical
solution, such as moving the speaker or microphone.
2.5.9 Using the Smaart RTA While Mixing
The RTA and Spectrograph have useful applications beyond
recognizing feedback spikes. The ability to analyze frequency content—
specifically, being able to visualize the exact frequencies you are
hearing in order to home in on problem areas— makes the RTA a
secret weapon for many a mix engineer. The Spectra tools also lend
themselves very well to ear training and give you confidence that
you are choosing the right frequencies when making adjustments.
Because the RTA/Spectrograph is analyzing the bus signal
digitally, room and speaker anomalies are taken out of the
equation. This provides a pure measurement of your mix because
you are measuring what is happening inside the console.
A Spectrograph shows the broadband information of a signal, making
it easy to view the fundamental frequency of a source, as well as its
harmonic structure. The RTA is a view of amplitude and frequency
content over a specified plane. With the Spectrograph, you can view
