The front panel of the BEHRINGER ULTRA-GRAPH PRO features six controls, six switches and 2 x 31 slide controls. Additionally, the GEQ3102 is equipped with two 12-digit LED meters. As all control elements are the same on both channels, this chapter deals with one channel only.

Use the I/O METER IN/OUT switch to toggle the meter between input and output level. When the switch is pressed, the ULTRA-GRAPH PRO displays the output level.

The AUDIO IN/OUT switch enables/disables the entire Equalizer section in the audio path. As this is a relay-controlled hard-bypass circuit, the inputs/outputs are directly connected as soon as the switch is released or the unit is switched off. Use the AUDIO IN/OUT switch to make A/B comparisons between direct and processed signals.

The LEVEL METER monitors the signal level to warn you of distortion. Depending on the setting of the I/O METER IN/OUT switch, this meter reads the input or output level (switch pressed). The red CLIP LED lights up at about +18 dB, i.e. 3 dB below clipping.

+Please note that extreme frequency boost in combination with high input levels can lead to distortion. In this case, it will be necessary to reduce the input level with the INPUT control.

The INPUT control adjusts the input level within a range from -15 to +15 dB.

The LOW CUT control determines the lower cutoff frequency of the ULTRA-GRAPH PRO. The high pass filter (18 dB/oct.) can be set from 10 through 400 Hz, in position “10 Hz” the signal passes unaffected.

The HIGH CUT control adjusts the upper cutoff frequency of the ULTRA-GRAPH PRO. The low pass filter (18 dB/oct.) can be set from 2.5 through 30 kHz, in position “30 kHz” the signal passes unaffected.

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.
