3.2 Equalizer in the monitor path

When using your ULTRAGRAPH PRO in the monitor path, the same applies as
when using it as described in section 3.1.
Basically, the stage volume should be as low as possible because:
1. this protects your hearing,
2. there are fewer feedback problems, and
3. it is easier to create a good FOH sound.
Often, monitor volume level is increased during a concert. Use intermissions in
the program to lower all monitor paths roughly 3 dB. The musicians will hardly
notice this reduction because their hearing can recover somewhat during an
intermission. This way you can achieve valuable headroom for possible use later
in the program.
Extremely deep frequencies are usually completely removed to avoid creating a
"queasy" feedback stage sound. To this end, use the low-cut filter and set it up in
such a way that extremely deep feedback completely disappears, creating a more
transparent monitor sound.

3.2.1 Priming a monitor system
Priming describes the process of detecting and supressing feedback frequencies.
After placing and leveling your mics and monitors (incl. power amps), you should
crank up the aux send controls of your mixer.
Now, activate the FBQ feedback detection system by pressing the FBQ switch (3) .
The slide control LEDs (9) will turn dark. Then, increase the amplification on your
mixer by using the aux send master control until you notice feedback starting to
occur. Feedback frequencies will now be easily visible through intensive lighting
of the relevant LEDs.
Pull down the slide controls whose LEDs are lit until the feedback subsides.
Repeat this procedure to weed out other possible feedback frequencies.
After having adjusted all critical frequencies, when you crank up the aux send
master control, you will be able to hear only the initial multi-frequency feedback.
Your monitors have reached their maximum volume.
Leave all other faders in the middle position as long as no need for frequency
correction occurs (e.g. measuring with a real-time analyzer). Set the desired
stage volume, and you will have a tremendous amount of headroom available
to you, without creating audible feedback.

3.3 Using the ULTRAGRAPH PRO in the studio

Additional applications await the ULTRAGRAPH PRO models in the studio.
No limits stand in the way of your imagination. Here are just a few examples
of possible uses:
EQing your studio monitors:
You can conduct a graphic equalization of your monitors. Besides, you can supress
narrow-band room resonance. An analyzer, for example the analyzer integrated
into our digital equalizer ULTRACURVE PRO DEQ2496, can help you when you are
looking for room resonance and a linear frequency response.
General sound processing:

Equalizers can be used to process both single-channel and master signals.
To process single-channel signals, you should connect the ULTRAGRAPH PRO
via the channel inserts on your mixer. To control several signals with your
ULTRAGRAPH PRO, use either subgroup or main mix inserts. Nowadays,
the overall sound of a mix is often "tweaked" with equalizers. Often, a mix is not

uniform, that is, frequency ranges are either too prominent or not prominent at

all. A graphic equalizer lets you find a fitting ratio between the intensity of these
various frequency ranges in order to achieve a homegenous sound.

3.4 Special sound effects

In recording studios as well as stage or radio plays, the ULTRAGRAPH PRO will be
your valuable sound tool for modifying the sound of voices (e.g. telephone voice)
or to filter instruments so that they fit in an existing mix.
The tables on the separate add-on sheet give you an idea of specific frequencies
and their acoustic significance, and suggest some possible uses for your
ULTRAGRAPH PRO.
