Behringer FEEDBACK DESTROYER PRO FBQ2496 Mode D'emploi page 13

(EN) Controls
(1) LEVEL METER – The LEVEL METER lets
you monitor the input level. Eight LEDs are
available per channel. If the Clip LED lights
up, digital distortion may occur on FBQ2496's
input. In this case, reduce the input level.
(2) LEARN button – A quick tap on the LEARN
button (LED lights up) gets you into the LEARN
mode. The FBQ2496 will immediately start
looking for critical frequencies and will deploy
as many Single-Shot filters as necessary
(of course, music or noise has to be present in
the room for this to work).
(3) PANIC – If unexpected feedback starts
occurring during a performance, pressing the
PANIC button can help. As long as the button
is kept pressed (for a maximum of 1 second),
your FBQ2496 rapidly searches for feedback
frequencies and suppresses them.
(4) SPEECH – Pressing the SPEECH button
increases the sensitivity of feedback
suppression; the FBQ2496 recognizes critical
frequencies sooner and deploys a filter that
cuts in appropriately.
(5) FREEZE – Once a particularly good FBQ2496
setting is achieved, you can keep this setting
by pressing the FREEZE button. All Single-Shot
and automatic filters are kept at their settings
until you press FREEZE again.
(6) FILTER LIFT – The so-called "Filter Lifting
Time" informs you about how long an
adjusted automatic filter can remain inactive
before its values are reset again. You can set
this time by first briefly pressing the FILTER
LIFT button and then turning the wheel.
The following time lengths are available:
0 min, 1 min, 5 min, 10 min, 30 min, 60 min.
(7) RESET – If you briefly press the RESET button,
all automatically set filters are erased. If you
keep the RESET button pressed longer, Single-
Shot filters are erased as well. In PEQ mode,
briefly pressing the RESET button erases the
selected filter. Keeping the RESET button
pressed longer erases all the parametric filters
all at once.
(8) STATUS DISPLAY – The FBQ2496 features a
total of 40 filters, i.e. 20 filters per channel.
They can be monitored and controlled on the
STATUS DISPLAY.
(9) LED DISPLAY – The three-digit numeric
display indicates the absolute value of the
parameter you are modifying.
GAIN – In the PEQ mode, the GAIN button lets
(10)
you adjust filter gain in dB (from +15 dB to
-15 dB in 0.5-dB increments, and from -16 dB
to -36 dB in 1-dB increments). The dB value
set using the wheel is shown in the display.
PEQ – After keeping the PEQ button pressed
(11)
for a few moments (the LED on the PEQ button
blinks), use the wheel to set the number
of parametric filters. They start with the
filter number 20 and can go down to filter
number 1, step by step. At the same time,
the already set Single-Shot filters are shown.
If you only briefly press the PEQ button
(the LED on the PEQ button is lit), any filter
can be called up using the wheel. The number
of the selected filter is shown in the display,
and the corresponding filter LED blinks.
Amplification, bandwidth and mid frequency
parameters can now be shown.
FREQUENCY – When the FBQ2496 is in the
(12)
PEQ mode (the LED on the PEQ button is lit),
the mid frequency of each individual filter can
be set. To modify the mid frequency, press the
FREQUENCY button. The frequency range can
vary from 20 Hz to 20 kHz.
LEFT-RIGHT – The LEFT-RIGHT button lets
(13)
you select the channels you wish to edit.
BANDWIDTH – Use the BANDWIDTH button
(14)
to set the bandwidth (Q-factor/quality) of the
selected parametric filter. The adjustable filter
quality encompasses a range from 1/60th
of an octave up to 10 octaves. The FBQ2496
has to be in PEQ mode (the LED on the PEQ
button is lit).
BYPASS – Keeping the BYPASS button
(15)
pressed for a few moments activates the hard
bypass. The unit's input is directly routed to
the output and the filters are bypassed.
MIDI – Simultaneously pressing BANDWIDTH
(16)
and BYPASS gets you into the MIDI menu
(both button LEDs are lit).
Quick Start Guide
WHEEL – WHEEL is a continuous rotary
(17)
control. Use it to make adjustments to the
selected parameter.
POWER
(18)
The mains connection is established using
(19)
a cable with an IEC mains connector.
An appropriate mains cable is included.
You can replace fuses at the FUSE SWITCH of
(20)
the FBQ2496. Always replace fuses with the
same type.
The FBQ2496 features a complete set of MIDI
(21)
functions. In addition to the usual MIDI IN
and MIDI OUT ports, the MIDI THRU allows
you to loop through MIDI data.
Use the OPERATING LEVEL switch to change
(22)
from home recording level (-10 dBV) to studio
level (+4 dBu), and vice versa. The level
meters are adapted automatically to the
selected nominal level, so that the FEEDBACK
DESTROYER PRO will always work in its
optimum operating range.
INPUT LEFT/RIGHT – These are the balanced
(23)
inputs of your FBQ2496. They are laid out as
¼" TRS and XLR connectors.
OUTPUT LEFT/RIGHT – Both of the FBQ2496
(24)
outputs are also laid out as balanced
¼" TRS and XLR connectors.
