The Lindell Audio PEQ-501A 500 Series Retro 2-Band Program Equalizer brings the timeless sound of the American classic EQP1 program equalizer into the modern, convenient 500 Series format. Designed for those who demand professional-level sound shaping, the PEQ-501A delivers smooth, musical highs and powerful low-end that have defined countless legendary recordings over the years. Whether you’re working with vocals, bass, or mixing entire tracks, this EQ brings warmth, clarity, and depth to every element of your sound. With a focus on ease of use and exceptional sound quality, it’s the perfect tool for engineers and producers who want the best of both worlds: vintage warmth with modern convenience.

Vintage Sound with Modern Build Quality
The PEQ-501A is built around the renowned 1731 op-amp, a key component in the legendary EQP1. This op-amp provides a rich, harmonic warmth that makes it ideal for enhancing both low and high frequencies with musicality and clarity. The hand-wound inductor further contributes to its vintage-inspired sound, allowing you to boost the lows and highs in a way that feels both natural and expressive. Gold-plated PCB internals ensure that the signal path remains clean and free of any unwanted distortion, delivering pristine audio quality. This combination of vintage sound and modern construction ensures that the PEQ-501A will stand the test of time, both sonically and physically.

Versatile Frequency Ranges for Fine-Tuning Your Sound
With an extended range of high and low frequencies, the PEQ-501A gives you precise control over your audio, allowing you to tailor the sound to your exact needs. The high-frequency range includes settings from 1kHz up to 16kHz, giving you the flexibility to enhance the brilliance of vocals or add air to stringed instruments. On the low end, you can select from 20Hz to 150Hz, making it perfect for adding weight to bass tracks or kick drums. This wide range of frequencies allows for total flexibility in shaping your sound, whether you're adding clarity to a vocal track or punch to your bass.

Stepped Controls for Accurate and Repeatable Settings
One of the standout features of the PEQ-501A is its stepped rotary controls, which provide precise, repeatable adjustments. Mastering engineers will especially appreciate this feature, as it allows them to recall settings with pinpoint accuracy. The stepped controls ensure that each adjustment is consistent, making it easier to fine-tune your sound and maintain the same settings across multiple sessions. Whether you're working in the studio or during live performances, the reliability of stepped controls makes your EQ adjustments both fast and precise, reducing the risk of over-compensating or losing your optimal settings.

Convenient Integration with 500 Series Racks
The PEQ-501A is designed to seamlessly integrate into any 500 Series rack, allowing you to take advantage of its powerful features without taking up excessive space. Its plug-and-play design makes it easy to install and use, whether you're a professional engineer or a hobbyist looking to expand your rack of audio gear. The real hardware bypass switch allows for quick A/B comparisons, making it easy to hear the differences your EQ settings are making. This intuitive design helps you maintain focus on the creative process while ensuring your sound shaping is as precise and effective as possible.

The gold-plated PCB internals not only improve signal integrity but also ensure that the unit remains reliable under frequent use. The robust build quality makes it ideal for both studio and live environments, withstanding the demands of regular operation while maintaining the same professional-level sound quality.
