2.3Using the ULTRA-GRAPH PRO in the studio

In the studio you can use your ULTRA-GRAPH PRO in a variety of further applications. Your imagination is the only limit. Here are just a few examples:

Equalizing monitoring speakers:

You can graphically equalize your monitoring speakers. Additionally, narrow-band room resonance frequencies can be suppressed with the ULTRA-GRAPH PRO. An analyzer (for example, the one integrated in our digital Equalizer ULTRA-CURVE PRO DSP8024) helps you identify room resonance and produce a linear frequency response.

General sound processing:

Equalizers can be used to process both single-channel and master signals. To process a single signal, you should use the channel insert point on your console to connect the ULTRA-GRAPH PRO. To control several signals, use either a Subgroup or Main Mix insert point. In particular, mastering studios frequently work with Equalizers to refine the sound of a finished mix. Often, the mix lacks balance, i.e. some frequencies are too loud or cannot be heard at all. With a Graphic Equalizer you can align the differing amplitudes of frequency ranges to create a homogenous sound image.

Chapter 3 (“THE SOUND TOOL”) provides useful information on how to process typical frequency ranges of voices and instruments.

3. THE SOUND TOOL

In recording studios as well as stage or radio plays, the ULTRA-GRAPH PRO will be your valuable sound tool to modify the sound of voices (e.g. telephone voice) or to filter instruments so that they fit in an existing mix.

The tables on the following pages give you an idea of specific frequencies and their acoustic significance, and suggest some possible uses of your ULTRA-GRAPH PRO.

3.1Effects of equalization on voice program

Center frequency (Hz)

Effect on voice

1/3 octave

 

40 to 125

Sense of power in some outstanding bass singers.

 

 

160 to 250

Voice fundamentals.

 

 

315 to 500

Important for voice quality.

 

 

630 to 1k

Important for voice naturalness. Too much boost in the 315 to 1 kHz

range produces a telephone-like quality.

 

 

 

 

Voice fricatives-accentuation of vocals. Important for speech

 

intelligibility. Too much boost between 2 and 4 kHz can mask certain

 

speech sounds e.g. "m", "b", and "v" can become indistinguishable.

1.25k to 4k

Too much boost anywhere between 1 and 4 kHz can produce

 

"listening fatigue". Vocals can be highlighted by slightly boosting the

 

vocal at 3 kHz and at the same time slightly dipping the instruments

 

at the same frequency.

 

 

5k to 8k

Accentuation of voice. The range from 1.25 to 8 kHz governs the

clarity of voice.

 

 

 

10k to 16k

Too much boost causes sibilance.
