Vintage EQ [ADV]

Overview

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”.

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.

LOW FREQUENCY BOOST

Sets the amount of boost applied to the selected low frequency. This is a low shelf filter.

LOW FREQUENCY CUT

Sets the amount of attenuation applied to the selected low frequency. This is also a low shelf filter.

HIGH BOOST FREQUENCY SELECTION

Sets the high frequency to be boosted. Options include 3 kHz, 4 kHz, 5 kHz, 8 kHz, 10 kHz, 12 kHz, and 16 kHz.

HIGH FREQUENCY BOOST

Sets the amount of boost applied to the selected high frequency. This is a peaking filter.

HIGH FREQUENCY Q

Sets the bandwidth for high frequency boosting. The boost amount and bandwidth interact (i.e., the Q changes as you boost), as they do in the EQP-1A.

HIGH CUT FREQUENCY SELECTION

Sets the high frequency to be attenuated. Options include 5 kHz, 10 kHz, and 20kHz.

HIGH FREQUENCY CUT

Sets the amount of attenuation applied to the selected high frequency. This is a high shelf filter.

Mid Frequency Controls

All of the mid frequency controls are peaking filters. As in the original MEQ-5, the filter bandwidths are affected by the boost/cut amount.

LOW-MID FREQUENCY SELECTION

Sets the low-mid frequency to be boosted. Options include 200 Hz, 300 Hz, 500 Hz, 700 Hz, and 1000 Hz.

LOW-MID FREQUENCY BOOST

Sets the amount of boost applied to the selected low-mid frequency.

MID FREQUENCY SELECTION

Sets the mid frequency to be attenuated. Options include 200 Hz, 300 Hz, 500 Hz, 700 Hz, 1 kHz, 1.5 kHz, 2 kHz, 3 kHz, 4 kHz, 5 kHz, and 7 kHz.

MID FREQUENCY CUT

Sets the amount of attenuation applied to the selected mid frequency.

HIGH-MID FREQUENCY SELECTION

Sets the high-mid frequency to be boosted. Options include 1.5 kHz, 2 kHz, 3 kHz, 4 kHz, and 5 kHz.

HIGH-MID FREQUENCY BOOST

Sets the amount of boost applied to the selected high-mid frequency.

M/S & L/R Controls

The Vintage Compressor offers Stereo, Mid/Side or Left/Right processing modes. See the Common Module Controls chapter for more information about Mid/Side & Left/Right processing modes.
