4ms LEQA Effect Module

Mix processing, sound shaping and stereo control directly in the Eurorack

With the Leveling EQ Amplifier – LEQA for short – 4ms presents an audio processor for the sophisticated processing of stereo signals. The LEQA is recommended as a backend module for enhancing a patch, the stereo bus or the entire mix. The module is inspired by the mastering classics, the LA-2A compressor and the 1073 EQ, and has been enhanced with a stereo width processor. To simplify operation, predefined curves and frequency selections are provided for intuitive mixing; this allows you to achieve great-sounding mixes with minimal effort.

The compressor operates with two ratios: 3:1 (Comp) and 10:1 (Limit). This covers two different processing approaches. The Gain Reduction and Make-Up Gain parameters are adjustable. The Dry/Wet control enables parallel compression, which has long been a tried-and-tested trick for fine-tuning amongst many mastering professionals. In the bypass position, the compressor is inactive.

The equaliser is a musical 4-band EQ featuring low-shelf and high-shelf filters with boost/cut controls, a mid-bell and a high-pass filter. Furthermore, the EQ can be routed either before or after the compressor section. The EQ Level control allows for detailed adjustments right through to dramatic effects.

The stereo width control performs mono-to-stereo and stereo-to-mono conversion, narrowing or widening the stereo image – all of which can be controlled via CV if required.

The LEQA is ideal for live performances, studio work, subtle tone colouring and extreme sound shaping, and is capable of blending different signals together.
