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.
