ULTRA-GRAPH PRO GEQ3102

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.

Voice fundamentals.

 

 

315 to 500

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.

GEQ3102 specifications

The Behringer GEQ3102 is a powerful 31-band graphic equalizer known for its exceptional performance and versatility, making it an ideal tool for sound engineers, musicians, and audio enthusiasts alike. Designed to provide precise control over audio frequencies, this graphic equalizer features two separate channels, allowing for comprehensive sound shaping in a variety of settings such as live performances, studio recordings, and installations.

One of the standout features of the GEQ3102 is its 31 bands of equalization. Each band operates at 1/3-octave intervals, spanning a frequency range from 20 Hz to 20 kHz. This extensive range enables users to fine-tune audio signals with remarkable detail. The equalizer provides a 12 dB boost or cut per band, allowing for substantial adjustments in frequency response to tailor the sound to the specific needs of each environment.

In addition to its impressive frequency handling, the GEQ3102 incorporates high-quality components to ensure clean and transparent audio. The use of low-noise op-amps and precision resistors minimizes distortion and colorations, delivering true sound reproduction. The equalizer is built on a robust chassis, capable of enduring the rigors of touring and live sound applications.

Another important characteristic of the GEQ3102 is its performance-enhancing technologies, which include boost/cut faders and a bypass switch. The faders allow users to make quick and intuitive adjustments, while the bypass function enables instant comparison between the equalized and unprocessed audio. This feature is especially useful for evaluating the impact of adjustments and ensuring the desired sound.

Furthermore, the GEQ3102 is designed with flexible connectivity options, including balanced XLR and TRS inputs and outputs. This ensures compatibility with a wide range of audio equipment, enhancing the versatility of the unit. Additionally, the graphic equalizer features LED level indicators for each channel, offering real-time monitoring of the signal level and ensuring optimal performance.

In summary, the Behringer GEQ3102 is an excellent choice for anyone seeking a reliable and effective graphic equalizer. With its extensive 31-band range, high-quality construction, and user-friendly design, it provides the necessary tools to shape sound accurately and effectively, making it a staple in any audio professional's toolkit. Whether for live sound reinforcement or studio applications, the GEQ3102 is sure to deliver exceptional audio performance.
