Empirical Labs ELQ Lil FrEQ
is a very versatile single channel audio equalizer that features a High Pass filter-high and low shelving-parametric and dynamic eq sections.
As with ELIs other signal processors, the Lil FrEQ Equalizer takes a somewhat unique approach to its job. Instead of daisy chaining several equalizers and frequency processors, we combined most of the sound sculpting tools an engineer needs into a compact single rack space box, while still offering the highest performance of any design in its class.
There are eight sections of processing; what other EQ offers that? Even better-in addition to a master bypass, each of the Lil FrEQs sections features its own dedicated bypass switch, letting you instantly A/B the effect of each section as you adjust and fine-tune them.
HIGH PASS:The High Pass section is a really easy to use sharp filter that cuts all content below one of eight preset frequencies from 30-330 Hz. This filter is very steep and has a special shape that prevents frequencies from thinning out just above the cutoff point. The corner frequency is selected using up/down buttons, and indicated by LEDs that glow softly when the section is bypassed, and brightly when the section is engaged.
HIGH and LOW SHELVING:These two knobs function similarly to the familiar bass and treble tone controls found on many consumer audio playback systems; however, these are designed to a much higher performance standard, providing exceptionally smooth and musical boost and cut on the high and low frequencies.
PARAMETRIC EQ:The Lil FrEQ has four sections of fully parametric EQ (LF, Lo Mid, Hi Mid and HF), with each section featuring individual gain, bandwidth (Q) and frequency controls. It may be the cleanest parametric EQ section ever produced, operating below .0007% THD (Total Harmonic Distortion) even at extremely high audio levels. Try finding those specs anywhere else!
DS (DYNAMIC EQ) - The DS section provides the highest performance, easiest to use, and possibly most natural sounding De-esser ever built. This powerful tool combines tunable filters with a compressor-like circuit that can help contain and control excessive high frequency content such as sibilants or other sharp transients, especially in the absence of other lower frequency content. It can also function as a one of a kind soft knee High Frequency limiter, which is one of the main things responsible for the Lil FrEQ becoming the go-to vocal EQ for engineers everywhere. It has been used on many acclaimed albums and major live performances all over the world, becoming the go to EQ for key tracks like lead vocals, snares, and bass. There are now dozens of hit record vocals that were processed thru the Lil FrEQ.
