Description

The Empirical Labs Lil FrEQ Equalizer Pair is a powerhouse of precision and flexibility for studio engineers demanding uncompromised audio quality. Housed in a compact single-rackspace unit, this dynamic duo combines eight sophisticated processing sections, including two shelf equalizers, a high-pass filter, and four fully parametric EQ bands. Whether taming troublesome frequencies or enhancing the natural warmth of your recordings, the Lil FrEQ ensures a seamless and professional outcome.

The high-pass filter offers eight selectable frequencies, providing a steep curve that meticulously preserves higher frequencies. Meanwhile, the high and low shelving sections deliver musical boosts and cuts, akin to high-grade tone controls. The dynamic EQ section employs a de-esser with a compressor-like circuit, perfect for smoothing out sibilance or unruly high-frequency content. This unique setup doubles as a soft-knee high-frequency limiter, making the Lil FrEQ an essential tool for vocal tracks and beyond.

The Lil FrEQ is not just about features—it's about performance. With DC-coupled inputs and outputs, and a Class-A transformer for the XLR output, this equalizer ensures pristine audio clarity and an authentic vintage vibe. Hand-wired in the USA, each unit promises durability and reliability, ready to meet the rigorous demands of both studio and live environments.

  • Eight sections of processing in a single unit
  • High-pass filter with eight selectable frequencies (30-330 Hz)

Empirical Labs' Lil FrEQ dazzles with its intuitive design and impressive sound sculpting capabilities, setting a new standard for analog equalizers. Its dynamic equalizer section excels, offering features previously only available through high-end software or multiple hardware units. The inclusion of dual output options and a top-notch instrument input jack elevates its versatility, making it a studio favorite. However, its few drawbacks include minor switch "pops" and the need for careful documentation due to non-stepped controls. Despite these, the Lil FrEQ offers unmatched fidelity and value, justifying its price and leaving users enamored with its performance.
