4ms Leveling EQ Amplifier [LEQA]　

The Leveling EQ Amplifier is an end-of-chain audio processor designed to polish individual elements of a patch, stereo bus, or full master bus.

Inspired by the simple interfaces and pleasing sounds of two cornerstones of mixing, the LA-2A optical compressor and the 1073 EQ, the LEQA combines a compressor, an equalizer, and a modern Stereo Width Processor in one 14HP package.


Rather than being fully parametric, pre-defined curves and frequency selections make the art of mixing intuitive. Very little effort is needed for great sounding mixes.

The compressor mimics optical compression, which is a beautifully simple concept that yields incredibly musical results.

The EQ section is built to help accentuate and excite your mix, clear up muddled sounds, and increase the overall headroom.

The Stereo Width Processor adjusts the stereo image, letting you dial back a wide image into a cohesive sound, or push a normal stereo signal into "super stereo" territory. When used with mono sources, it can widen mono sources into stereo using a combination of psychoacoustic techniques.

The Leveling EQ Amplifier excels in live performances, studio work, subtle utility tasks, extreme sonic sculpting, audio "glue" to hold a patch together, and as an effect in its own right.

Stereo Width

• Mono to stereo conversion using a unique take on the Haas Effect
• Stereo field manipulation for tightening a stereo image, stereo-to- mono conversion, or larger-than-life super stereo effects
• Knob and CV control over stereo width

Equalization

• Four filters with tailored frequencies for maximum musicality
• Low-shelf, Mid-range bell, and High-shelf filters with boost/cut controls, plus an additional High-pass with selectable frequency
• Flexible routing that allows the EQ to be pre- or post-compressor section, or bypassed
• Global selectable EQ gain for detailed control or drastic effects

Compressor

• Compression and limiting inspired by optical compression from the 1970s, with two ratios: 3:1 (Comp) and 10:1 (Limit)
• Controllable gain reduction and make-up gain
• VU-meter displays gain reduction in real time
• Dry/wet mix control over compression for parallel compression application
• Bypass switch
