ULTRA-GRAPH PRO GEQ3102

+Good equalizer settings require time and patience! If you need to use extreme EQ settings to achieve an acceptable frequency response, the reason might be some serious misalignment of sound reinforcement system or room acoustics.

Equalizers cannot make up for poor audio systems, but they are extremely useful and efficient tools for making musical fine-adjustments, as this often produces astounding improvements in terms of acoustic power and overall sound quality.

2.2 Equalizer in the monitor path

To use the ULTRA-GRAPH PRO in the monitor path, you should basically follow the same procedure as described in section 2.1.

On stage, you should keep volume levels as low as possible, because:

1.this will protect your ears,

2.avoid feedback problems, and

3.make it easier to create a well-balanced FOH sound.

Often, the volume of the monitors is raised during concerts. Use concert pauses to reduce the levels of all monitor paths by about 3 dB. The musicians on stage will hardly notice this reduction (or even not at all), because their hearing, too, can relax a bit during the break. This method will give you valuable headroom.

Extremely low frequencies are usually faded out completely, to avoid a stage sound that lacks transparency due to low frequency feedback. Apply the low cut filter until extremely low-end feedback frequencies are eliminated and the overall transparency of the monitors is improved.

This illustration gives you an example of how to use several ULTRA-GRAPH PRO’s in an 8-way monitor system.

2.2.1 “Tuning in” of a monitor system

“Tuning in” describes the process of detecting and suppressing feedback frequencies. Once all microphones and monitor speaker (plus power amps) have been set up and adjusted, you should turn up all Aux Send controls in those channels of your console that you will need for the monitor mix. Then, turn up the master Aux Send control until the first feedback occurs. Turn the control down a bit and leave it where there is no feedback. Now turn up the single slide controls on your ULTRA-GRAPH PRO, one after the other. Whenever feedback occurs, set the slide control of the respective frequency range to maximum cut. When there is no feedback, leave the control in mid-travel position. Finally, you can turn up the master Aux Send control without running the risk of audible feedback.

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.
