#1240 DP_St.EQ45¶
Eventide’s EQ45 is based on the Urei 545 parametric EQ. The high resolution and flexibility of its filters and the wide number of parameters offered by the user interface enable you to perform subtle or drastic changes to audio material without the unpleasant artifacts that can often result from limited dynamic range in hi Q filters (single precision arithmetic).
The EQ45 includes the following components and controls:
Three overlapping band controls covering 20 Hz – 16 kHz. Frequency Ranges:
Low Band: 20Hz–500 Hz
Mid Band: 180 Hz – 3.6 kHz
High Band: 800 Hz – 16 kHz
One multiband control covering the entire audio spectrum (12 Hz – 20 kHz).
High-cut and low-cut Butterworth filter sections, with attenuations of 12 dB/octave beyond their respective -3 dB points.
Cutoff Filters Frequency Ranges:
Low cut: 5 Hz – 1000 Hz, continuously tunable
High cut: 400 Hz – 20 kHz, continuously tunable
Accompanying Q and Gain controls for each parametric filter section. The Q controls support values from 1/4 octave to 2 octaves; the Gain facility allows attenuation and boost from -15 dB to 15 dB.
An EQ In/Out toggle. Click the object to enable it and to use the full suite of parametric filter; disable it to use only the high- and low-cut filters.

#1241 DP_St.EQ65¶
Eventide’s EQ65 is based on the Urei 565 filter set, which allows you to adeptly de-emphasize or completely eliminate selected frequencies in an audio recording. This is accomplished through its dual notch and peak filters, which can be precisely configured using the fine tuning control. Designated frequencies also may be attenuated in gradations by using the notch filters in conjunction with the depth controls.
- Timbre Shaping
The EQ65 can be used to subtly shape the tonality of a note of voice or single instrument with rich harmonic content by tuning the notch/peak filters to the fundamental and/or any combination of the harmonics. By adjusting the relative levels of the harmonics, a wide palette of tonality is possible. As described above, multiple instances of the EQ65 can be ganged to handle any number of harmonics.
- Notching Narrow Band Coherent Noise
With its precision frequency selectivity and high Q, the EQ65’s notch filter is extremely effective at eliminating undesirable coherent signals such as hums and whistles. To do this, set the center frequency to the fundamental of the unwanted signal using the coarse and fine controls. Use the notch/peak shape selector to select the most effective notch shape. It is often helpful to select the peak mode to help zero in on the target frequency. You can audition the filter’s effect using the in/out switch. Signals with significant harmonic content can be attenuated by combining the pair of notch filters. Set one to the frequency of the fundamental and the other to the most prominent harmonic. If additional harmonics are present, you can gang additional instances of the EQ65 and tune the additional notch filters to the higher harmonics.
- Eliminating Broad Band Low Frequency or High Frequency Noise
The EQ65’s low pass and high pass filters have sharp roll-offs and extreme stop-band attenuation. This optimized design facilitates eliminating low-frequency rumble and high-frequency hiss.
- Simulations/Special Effects
The precise frequency control and flexibility of the EQ65 can be used to simulate distorted phone lines, cell phones, etc.
