Typical Set-Up

NADY AUDIO graphic equalizers may be used wherever modifi- cation of the frequency contour of a sound system is needed. A graphic equalizer is a solution to any number of sound problems or creative urges.

SOUND REINFORCEMENT APPLICATIONS

By routing the signal from the mixer to the main power amplifiers (or crossover), the overall frequency of the mix may be altered to do a number of things.

A.Through the use of a real-time audio spectrum analyzer, a calibrated microphone, and a pink noise source, the audio system may be “TUNED” to make the overall audio spectrum response of the audio reinforcement system and the room environment flatter in its frequency response.

B.By turning up the audio reinforcement system to the feedback point, then attenuating the oscillating frequency (1/3 octave resolution), then turning the system up to attenuate the 2nd oscillating frequency, and then the 3rd, and so on, you can enable the entire audio system to have much more gain before feedback.

C.Amplifiers and speakers may be protected by the use of the LOW CUT feature of the equalizer. Wind noise or the loud percussive sound of dropped microphones, etc., could potentially cause damage to the amps and/or speakers. By rolling off the extreme LOW frequencies with the LOW CUT filter, a measure of protection is added to the system without severely affecting the overall sound quality.

D.In noisy environments, the audio signal may be tailored for better intelligibility and penetration. This is especially useful for public address systems.

E.Creative use of the equalizer allows shaping of the signal for a more pleasing sound or for special effects. The only limits are those of taste and imagination.

MUSICAL INSTRUMENT APPLICATIONS

A.Putting an equalizer in line with a musical instrument allows you to modify the sound of the instrument. You can brighten the sound, or add body to a thin sounding instrument, or even give the sound a totally different character.

B.An equalizer will allow you to eliminate unwanted sounds, like a 60-cycle HUM from a badly grounded amplifier.

STUDIO APPLICATIONS

A graphic equalizer is one of the most useful tools in the sound

engineer’s bag. NADY AUDIO equalizers offer the features and flexibility to perform where it counts in the studio.

A.Fix a track that doesn’t sound quite right. Put the equalizer in an effects send and return it to the MIX bus.

B.Create an artificial stereo by splitting a monaural signal and equalizing the split signals differently, then panning one equalized signal to the right and the other signal to the left.

C.Shape the sound by changing the frequency response of the track.

D.Special effects, like a telephone sound, can be created by cutting off the LOW end to 200Hz and the HIGH end to 6KHz.

GEQ215, GEQ131, GEQ231 specifications

Nady Systems is a leading name in the audio industry, known for developing high-quality audio equipment, including graphic equalizers. Among their notable products are the GEQ231, GEQ131, and GEQ215 models. Each of these graphic equalizers is designed to enhance sound quality in various audio applications, catering to the needs of musicians, sound engineers, and audio enthusiasts alike.

The GEQ231 is a versatile 31-band graphic equalizer that provides precise control over audio frequencies. With its two-channel design, it offers individual control for each channel, allowing for tailored adjustments to fit the specific acoustics of any venue. This model features a 45mm fader for each frequency band, providing smooth and accurate frequency adjustment. The GEQ231 also includes signal LEDs for monitoring input and output levels, ensuring that sound professionals can maintain optimal performance levels.

In contrast, the GEQ131 offers a more compact solution with its 15-band configuration. This model is ideal for smaller setups or environments where space is limited. Despite its smaller size, the GEQ131 does not compromise on performance; it retains the essential features that allow sound engineers to sculpt their audio perfectly. The sleek design and rugged construction make it suitable for both studio and live applications.

The GEQ215, on the other hand, is another dual-channel 15-band graphic equalizer designed for more extensive sound systems. It incorporates a low cut filter and an unbalanced insert loop for added flexibility in sound processing. Like its counterparts, the GEQ215 boasts high-quality components for reliable, consistent performance.

All three models utilize true 24-bit digital signal processing technology, ensuring minimal distortion and maximized audio clarity. The rear panel connectivity options are robust, featuring XLR and 1/4-inch TRS inputs and outputs, making these equalizers compatible with a wide range of audio equipment.

With their user-friendly interface, durable build quality, and outstanding audio performance, the Nady Systems GEQ231, GEQ131, and GEQ215 graphic equalizers are excellent choices for anyone looking to elevate their audio experience. Whether you are mixing live sound or fine-tuning recordings in the studio, these equalizers provide the flexibility and precision necessary to achieve the desired sonic landscape.
