Passive equalizers have been an essential part of audio production since the early 1950s. Among them, the iconic Pultec EQP-1 stands out as the first to integrate passive filter circuits with high-quality line amplifiers. While renowned for its ability to transform virtually any sound, the EQP-1 had a notable limitation: it lacked the precision needed for isolating specific frequencies. Despite this, many modern equalizers have been modeled after the EQP-1, replicating its structure and functionality. However, these designs can feel restrictive in today’s dynamic and versatile music production landscape.
The Gainlab Audio Empress 2×3 Band Tube Equalizer was created to address these limitations and elevate the classic design. By introducing a mid-frequency filter between the low and high bands, the Empress significantly enhances flexibility, meeting the demands of contemporary music production. The unit retains the hallmark feature of simultaneous cutting and boosting in the low and high bands, enabling the signature tonal shaping tricks expected of an advanced equalizer. Moreover, the innovative shift function allows the midpoints of the simultaneous cut and boost to be shifted relative to one another, opening up new possibilities for frequency manipulation.
Extensive testing in real-world applications has demonstrated the Empress’s remarkable versatility. Whether used for recording, mastering, or creative sound design, it consistently exceeds expectations. From subtle tonal enhancements to extreme sound sculpting, the Empress excels across the full frequency spectrum. Its ability to deliver exceptional results in challenging conditions inspired its name, symbolizing its reign over the sonic domain.
