What it is

The UADx Pultec Passive EQ Collection bundles three circuit-modeled emulations of the most-used vintage Pultec hardware EQs: the EQP-1A program equalizer, the MEQ-5 midrange EQ, and the HLF-3C high/low frequency filter. The Pultec EQP-1A is one of the most recorded-about pieces of hardware in music history - its simultaneous boost and cut at the same low frequency creates a resonant bump that has defined the sound of drums, bass, and guitars across decades of popular music.

Who it's for

Mixing engineers who want the tonal fingerprint of classic Pultec EQs without the hardware price tag. The EQP-1A is a go-to for adding low-end weight and high-frequency air, the MEQ-5 handles midrange texture on guitars and keys, and the HLF-3C works as a surgical high/low pass filter with vintage character.

Key features

• The EQP-1A's simultaneous boost/cut at low frequencies produces the resonant low-end enhancement that has been used on nearly every genre since the 1950s
• The MEQ-5 covers 200Hz to 7kHz midrange shaping with a smooth, musical curve that avoids harshness
• The HLF-3C provides precise high and low frequency cuts for cleaning up tracks without the sterility of modern digital filters
• All three models include the transformer saturation and tube harmonic character of the original circuits
