Vintage EQ (Advanced only)
The Vintage EQ module is based on the Pultec EQP-1A and Pultec MEQ-5, two highly regarded
equalizers from the 1950s. EQP-1A aects the high and low frequencies, and MEQ-5 acts on the
midrange. The Ozone Vintage EQ closely emulates the frequency response of the Pultec EQP-1A and
MEQ-5 by modeling their individual circuit components.
A unique property of the EQP-1A is that it has separate controls for boosting and cutting the low
frequencies. While the original manual warns “Do not attempt to boost and attenuate simultaneously,”
these controls interact in a way that many engineers have found to be extremely desirable. Rather
than canceling each other out, combining these controls results in a boost in the low frequencies,
followed by a dip slightly higher up. This unique filter shape is also available in our Equalizer module
as the “Vintage Low Shelf”.
Key Features
• Adds the richness, warmth, and color of analog equalization to your audio.
• Models the qualities and experience of Pultec hardware equalizers for a unique, musical way to
manage equalization.
• Mid/Side and Left/Right processing modes give you unprecedented control over the stereo
soundstage.
High & Low frequency controls
Low Frequency Selection
Sets the low frequency to be boosted. Options include 20 Hz, 30 Hz, 45 Hz, 60 Hz, and 100 Hz. The
45 Hz option isn’t present in the original hardware unit, but we’ve added this frequency because we
found it to be useful for mastering.
