Electro-Voice
– GAIN - sets the amount of increase or reduction of the equalization filter.
LOW/HI SHELF - Shapes the sound using a shelving type filter that can be applied to the low
frequency or high frequency response using two controls:
–
FREQ - sets the center frequency of the filter. For the LOW SHELF filter the GAIN of the
filter tapers off above the frequency selected. For the HIGH SHELF filter the GAIN of the
filter tapers off below the frequency selected.
– GAIN - sets the amount of increase or reduction of the signal below or above the FREQ
setting.
LOW/HI PASS - Pass band filters that shape the sound by only passing signal above or below
the selected frequency.
–
FREQ - sets the corner frequency for the pass band filter. For HI PASS filters all
frequencies above the selection will be passed through. Frequencies below the setting
will be tapered off. For
LOW PASS filters all frequencies below the selection will be
passed through. Frequencies above the selection will be tapered off.
MAIN GEQ menu
The MAIN GEQ menu is used to adjust the frequency response of the loudspeaker for
different applications or personal preference. There are seven different EQ filters available
centered at the following frequencies: 63, 160, 400, 1.0K, 2.5K, 6.0K & 12K Hz. The filter is
also independent of the
MAIN GEQ setting if AUX OUT is set to MAIN MIX .
The range of each filter is -12 dB to +12 dB.
The default value for each filter is
0 dB .
FX & FX ENABLE
The FX control is used to select the desired effect (e.g. reverb, chorus, delay, etc.) to apply to
the FX send. The FX send level is independently controlled in the INPUT 1 and INPUT 2 FX
control. The
FX ENABLE turns ON or OFF the effect globally. FX ENABLE can be toggled with
a footswitch.
AFS (automatic feedback suppression)
The 12-band automatic feedback suppression (AFS) can be engaged to reduce unwanted
feedback frequencies when microphones or instruments with pickups are used. Feedback
occurs when sound from the loudspeaker enters the microphone or pickup and is amplified by
the loudspeaker and played back again. High levels or extended periods of feedback can
damage hearing and equipment.
Available options for this selection are
OFF and ON .
Reducing feedback
To reduce feedback:
1.
Set the loudspeaker and microphone or instrument according to your performance.
Follow appropriate microphone placement and use practices:
– Do not place the microphone directly in front of the loudspeaker. Refer to the user
manual of your microphone to know the pickup and rejection patterns of your
microphone.
– Avoid placing music stands, tablets, or other large flat objects near the microphone such
that they can cause audio reflections into the microphone.
– Use proper microphone technique when speaking, singing or placing by an instrument to
avoid using excessive input gain. For example, hold the microphone close to your mouth
when performing.
– Engage appropriate input channel PRESET for your application: LOW CUT 80 Hz ,
LOW CUT 120 Hz , VOCAL MIC , VOICE FILTER , SPEECH , ACOUSTIC GUITAR , etc. Refer
to INPUT DSP control menu, page 46.
