2. Select the graphic EQ for the aux output of the stage monitor you are ringing out
3. Enable the spectrograph.
4. Slowly bring the aux output level up until you hear (and see) feedback.
Note: Ringing out stage monitors will produce feedback. If you are not careful, you can produce a lot of
feedback. Do not make sudden gain boosts; go slowly and carefully to avoid causing any damage to
speakers and ears.
5. Feedback will show up as a solid line on the spectrograph and as a line peak on the RTA. Use the
dynamic threshold to adjust how bright, and at what input level, the frequency information plots.
6. Lower the GEQ fader for the offending frequency in 3 dB increments to attenuate it out of your
stage monitor.
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 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
lavaliere 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.
8.3 Using the RTA While Mixing
The RTA provides a view of amplitude and frequency content over a specified plane. 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 it a secret weapon for many mix engineers.
Because the RTA is analyzing the channel or 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 your StudioLive.
Power User Tip: The RTA can be useful in understanding what the frequency content of an instrument when
creating space for it in a mix. For example, let’s say you are mixing a particularly edgy-sounding lead guitar
that is competing with the male vocal and distracting from the overall good tone of the instrument. By using
the RTA in the Fat Channel, you can quickly identify the offending frequency by looking for spikes in the RTA.
This saves time and frustration by taking some of the guesswork out of equalization. It should be noted,
however, that an RTA cannot be used as a substitute for careful listening. While this tool provides a great
visual analysis of your mix, critical listening must always be your main guide.
