FEEDBACK DESTROYER PRO FBQ2496 User Manual
5.3  FBQ2496 in studio applications
Thanks to the FBQ2496’s flexible configuration, it makes perfect sense to use it at 
the studio or for home recordings. When in Parametric EQ mode, the FEEDBACK 
DESTROYER PRO puts up to 20 fully parametric equalizers per audio channel at 
your disposal. Everything is possible: from simple signal processing to total signal 
manipulation. For example, you can also use the FBQ2496 to remove distortion 
from your studio monitors, or you may use it to aid the EQ function on your 
mixing console if it only has semi-parametric EQs.
6.  Incoming Signal Level
Make sure that the level of the signal being fed into your FBQ2496 is always 
correctly set! That way, the FBQ2496 will always be able to effectively suppress 
feedback. To correctly set the signal level, use the LEVEL METER display 
(1)
The upper clip LEDs should ideally never light up. At any rate, aim to avoid the clip 
LEDs constantly being lit up.
If the signal level is too low, the music looses its dynamics, and the result is 
a weak, hissing sound that does not set itself through. Similarly, you should 
avoid at all cost signal levels that are too high because they will overdrive 
the FBQ2496 converters. Digital distortion (unlike its analog counterpart) 
is extremely unpleasant because such distortion does not occur gradually but 
extremely abruptly.
7.  MIDI control
MIDI stands for “Musical Instrument Digital Interface.” It is a “language” used to 
transmit control information between different electronic devices: instruments, 
PCs, drum computers, effects units, etc. That way, a device
s parameters can be 
automatically modified at a previously determined point in time.
To make such communication possible, the following conditions have to be met:
All devices must be correctly connected to one another.
One device, called “master,” sends MIDI information via one or several MIDI 
channels. The device receiving control information, called “slave,” has to be 
set to the correct MIDI channel in order to receive the information.
The control information being sent has to be “understood” by the MIDI 
devices receiving it.
7.1  MIDI connections
The MIDI connectors found on the rear panel are on internationally standardized 
5-pin DIN jacks. You need dedicated MIDI cables to connect the FBQ2496 to 
other MIDI equipment. Normally, complete cables will be purchased for this use. 
MIDI cables should have a maximum length not exceeding 15 meters.
MIDI IN: Receives MIDI control data. The receive channel is determined in the 
SETUP menu.
MIDI THRU: Provides an unchanged copy of the signal received at the MIDI IN, 
for example, to daisy-chain several FBQ2496.
MIDI OUT: Transmits MIDI data to a connected computer or other FBQ2496. 
Transmitted are program data as well as status information for signal processing.
◊ 
No loop lines are allowed with MIDI connections, i.e. the master device 
can send only control information, and the slave device(s) can only 
receive control information–and not the other way around. Depending 
on your application, some devices can function both as masters 
and slaves.
7.2  Activating and deactivating MIDI
With some applications, having the option to disable the MIDI function of a 
device can be useful. This means that the device does not react to the incoming 
MIDI control data; instead, it merely passes the incoming MIDI signal through.
The FBQ2496 gives you the option to decide whether it should react to incoming 
MIDI control data.
◊ 
Even when the MIDI function is deactivated on the FBQ2496, the MIDI 
signal still passes through the unit and can be tapped into at the MIDI 
THRU connector.
1.  Press BANDWIDTH and BYPASS simultaneously. The MIDI menu is activated 
if the LEDs on both buttons as well as the MIDI LED under the display 
are blinking.
2.  Press the BANDWIDTH button; then use the wheel to activate or 
deactivate MIDI. 
MIDI on: on 
 
MIDI off: off
3.  Press any button to exit this menu.
7.3  Adjusting a MIDI channel
Using a MIDI channel, a master can transmit 16 different data segments, each one 
using its own channel. To make sure a slave only receives the information 
intended for it, the corresponding MIDI channels have to be assigned to it first.
1.  Press BANDWIDTH and BYPASS simultaneously. The MIDI menu is activated 
if the LEDs on both buttons as well as the MIDI LED under the display 
are blinking.
2.  Press BANDWIDTH again. Now, a MIDI channel can be selected using the 
wheel. The display shows channel numbers as follows: c 1, ... c14, c15, c16.
3.  Press any button to exit this menu.
7.4  MIDI controller
Each one of the 16 MIDI channels can transmit a lot of different information– 
for example, note, keystroke strength and the so-called controllers.
A controller is a command (e.g. instrument, volume, balance, footswitch position) 
that in certain situations has to be defined very specifically. A total of 128 
different controllers can be set up. There are several standards (0 = bank select, 
7 = main volume) but no fixed norm for the assignment of controllers to specific 
controller numbers (0 - 127) exists. Different MIDI devices may react differently to 
the same controller numbers.
To effectively control your FBQ2496, it is important to know which controller 
numbers can influence individual parameters.
