Empirical Labs Lil FrEQ – 1U Analog EQ with Dynamic Section & Instrument Pre

The Lil FrEQ is a breakthrough in analog equalization—a single-rackspace powerhouse offering six creative EQ types plus a high-performance dynamic section. With ultra-clean parametric bands, musical shelving, de-ess/soft-knee limiting, and even an instrument input, it delivers mastering-grade tone and intuitive control.

Key Features

• High-pass filter: Sharp 3rd-order “colored” filter with eight selectable cut frequencies and responsive LED indicators.
• High & low shelving: Smooth, musical tone shaping for subtle or bold tonal sculpting.
• Four parametric bands: LF, Lo-Mid, Hi-Mid, HF with gain, Q, and frequency controls, operable at below 0.0007% THD.
• Dynamic EQ section (DS): Use as a natural-sounding de-esser or HF soft-knee limiter—highly musical, compressor-based tonal smoothing.
• Instrument input / DI: Front-panel jack for connecting bass or guitar directly, with ultra-clean circuitry and low distortion.
• Dual outputs: DC-coupled active output plus Class-A transformer output for tone variety and analog warmth.

Customer Benefits

The Lil FrEQ offers precision and personality in one compact unit. Its clean parametric bands and flexible filtering enable refined tone sculpting, while the DS section smooths sibilance or harsh tops gracefully. With its DI capability and output versatility, it doubles as a tone-enhancing preamp, making it perfect for tracking, mixing, or mastering.
