Using the Graphic Equalizer
Unlike the HIGH, MID-MORPH, and LOW controls on each channel that adjust only the
tone of their own input signals, the seven-band graphic equalizer adjusts the tonal
balance of all the signals going through the powered mixer. This graphic equalizer is also
a powerful tool to help reduce or eliminate acoustic feedback. This offers the user great
flexibility in adjusting the sound, but use moderation in making these adjustments.
FLS
®
Feedback Locating System
The FLS (Feedback Locating System) LED indicators are invaluable tools in helping to
reduce/eliminate feedback. Acoustic feedback is the loud howl or squealing sound
heard through sound systems as the result of sound from the speakers re-entering the
microphones. To use the FLS feature, start by setting all graphic EQ sliders (Fig. 20)
to 0. Then before the audience arrives, increase the MASTER LEVEL and/or CHANNEL
LEVEL until feedback occurs. Note which LED illuminates and slightly lower the
corresponding slider. This reduces gain at the feedback frequency and can be repeated
if necessary to improve gain before feedback. Only adjust the sliders a small amount to
avoid adversely affecting sound quality.

GENERAL USE TIPS:
Avoiding Acoustic Feedback
When encountering feedback it is always best to start looking at the placement of the mics and speakers in the system before resorting
to equalization (EQ) adjustments. Make sure that the speakers are positioned to direct the sound toward the audience and away from the
microphones. Position mics as close to the sound source as reasonable. Moving the mic closer increases the volume of the sound through the
system without having to turn up the gain.
Microphone Usage Guidelines
When practical, a single microphone is preferred. Additional microphones pick up more sound from the speakers and each mic must then be
turned down to prevent feedback. However, if you have difficulty balancing the level of different individuals with one mic or if you still cannot
get sufficient gain, using more mics can offer an advantage. For example, giving several singers their own microphone allows placement of
the microphones much closer to each singer. This increases the volume of the sound at the mic and far outweighs any detrimental effect from
using multiple mics. It also allows the volume of each mic to be adjusted separately for proper balance.
Packing the Escort
®
One of the Escort’s many benefits is that the entire sound system can be packed inside its easily transportable case (Fig.21). Begin by folding
the speaker stands, then secure them into their storage compartment using the two straps. Place the optional microphone(s) in their storage
compartment, putting the cables in the other compartment or with the speaker stands. Lay the speakers face down on top of the bottom tray
and secure the four latches. The Escort is now ready to be carried or pulled on its built-in, luggage-style wheels.
