Peavey Escort 5000, Руководство по эксплуатации

Страница: 21 / 36

Much of the setup of the Escort ® is similar to the setup of other sound systems, and many aspects require plain common sense.
Safety should always be your first concern. Always use grounded outlets and three-wire extension cords. Run sound system cables
in a way to prevent the danger of tripping and tape them down if needed. Place the speaker stands and mixer on a solid, level
surface. Following these guidelines will help prevent personal injury and equipment damage, ensuring years of trouble-free use.
THINK SAFETY FIRST!
Setup Guide
Setting Up Mixer and Speakers
Place closed unit so speakers are upward. Release latches by lifting up until the latch disengages. Remove the speakers from the case.
NOTE: The latches can be closed after speakers are removed. This is recommended to avoid interference with removal of other
components. This will also help avoid damage to the latches. Close the latch by pushing in until it is flush with the side of the case, then
push down until it locks.
Remove the speaker stands from the case. Be sure the legs on the stand are fully extended to provide a stable base for the speakers and are
positioned on a level surface. Tighten the thumbscrew on the base so that it is snug, but do not overtighten (Fig.1). Raise the speaker stands to
the desired height, tighten the thumbscrew and install the safety pin as shown (Fig.2).
WARNING! Only connect the included speakers to the mixer. Escort
speakers provide optimal load for the powered mixer and using
other speakers may result in equipment damage.
Place speakers on stands and position them so that they will face toward the audience and away from the microphones (Fig.3). Connect speaker
cables from the jack on the lower front of the speaker to the speaker outputs on the back of the mixer. Connect the left speaker to the LEFT
OUTPUT and the right speaker to the RIGHT OUTPUT (Fig.4).

The FLS
®
(Feedback Locating System) LED indicators are invaluable tools in helping to reduce/eliminate feedback. To
use the FLS feature, start by setting all graphic EQ sliders (Fig. 9) to 0. Then, before the audience arrives, increase the
MASTER VOLUME and/or CHANNEL GAIN until feedback occurs. Note which LED illuminates and slightly lower
the corresponding slider. This reduces the gain at the feedback frequency, and can be repeated if necessary to improve
gain before feedback. However, only lower the sliders in small amounts to avoid adversely affecting sound quality.

Avoiding Acoustic 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. Although it does an excellent job of getting the audience’s attention, feedback
should be avoided. When trying to deal with acoustic feedback it is always best to start looking at the placement of the
mics and speakers in the system before resorting to equalization (EQ) adjustment. 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 has to be turned down a little 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.
Giving several singers their own microphones, for example, 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.
Reverb
Adding reverberation to music can enhance the sound of that music. To add reverb to a microphone, simply turn up the
REVERB control (Fig. 7) on the appropriate input channel. Add reverb in moderation because too much reverb makes
vocals hard to understand. In most cases, it is best not to add reverb to the spoken word.
Stereo / Mono Operation
The Escort
™
2000 powered mixer has two input channels (4 & 5) for stereo line sources. If the speakers are situated so
that most of the audience can hear both speakers (Fig. 10 A), it can be advantageous to run the system in stereo. If the
audience primarily hears just one speaker (Fig. 10 B), or if you are using one speaker for the audience and the other for
the stage performers, then it is best to run the system in mono.
