This Classic American 4-Band EQ-Preamp enhances audio mixing with its refined analog-inspired design. Building upon a simpler three-band predecessor, it introduces a fourth EQ band to provide greater control over the sound spectrum. The module is based on an all-discrete, custom op-amp circuit that replicates the character and warmth of the original hardware. Its four peaking bands offer seven carefully selected frequencies, enabling detailed tonal shaping that covers a wide range of audio frequencies.

The EQ module allows for overlapping bands, creating complex equalization curves that are essential for achieving precise balance and positioning of individual tracks in a mix. It operates within the T-RackS CS Standalone application and supports high-quality oversampling along with high-precision digital processors to deliver transparent and accurate sound reproduction. The analog-modeled design preserves the vintage character of classic hardware while supporting modern workflows with full-latency compensation and sampling rates up to 192 kHz.

As part of the T-RackS CS Custom Shop collection, this module offers flexible access through an integrated online store. Users can try any processor for 14 days and purchase modules using credits or currency directly within the platform.
