SonEQ Pro details
SonEQ Pro’s low frequency controls consist of two filters that work interactively. One boosts lows while the other attenuates. Since boost and attenuation curves are not perfectly aligned, SonEQ Pro’s handling of low-frequency equalization generates cancellations and summations which sound quite natural and pleasing to the ear.
Used alone, the low boost control acts as a normal low-shelf. Likewise, when the attenuation control is used exclusively it will act as a low-cut shelf to attenuate low frequencies. Cancellation and summation of low-frequencies occur only when boost and attenuation are used in conjunction with one another.
As a workflow practice, we recommend boosting bass with SonEQ Pro first and then, if necessary, adjusting the “low atten” knob to achieve the desired sound.
Bell switch: If you do not need to apply a low shelf, low´s band can be used as a bell filter, ranging from 20Hz to 100Hz.
Frequency, boost, and Q controls all affect the shape of the bell filter. The boost and Q controls work interactively. As Q is increased the shape of the bell is narrowed, and its level of enhancement over the source is increased proportionally.
SonEQ’s mid-band is recommended to equalize midrange frequencies ranging from 70 Hz to 2000 Hz. It´s a bell filter with a generally soft, very musical sound. Nonetheless, this band can be very aggressive if required, depending on the amount of gain applied.
HiQ, unlike its younger brother, can be used in a “surgical” way. For example, with HiQ enabled, the user may “sweep” through the frequency range to remove annoying resonances or frequencies. With smaller gain values, HiQ can also be used musically if desired.
Recommended equalizing mids and high-mids, from 1000 Hz to 6800 Hz. In comparison with the band described above, the high-mid band features a larger bandwidth, making it ideal for this type of frequency equalization. It sounds very musical and natural, due to its large bandwidth and smoothly shaped bell.
The high-mid band can be used for any type of application, for example: to enhance the clarity of a singer’s voice, lend a guitar more presence, and even to make an entire mix sound more natural.
Activating the “Mid Q” setting will reduce frequency bandwidth, giving high-mid equalization a slightly more aggressive property, suitable to lend more attack kick drums, bass guitars, or any instrument requiring a bit more punch.
SonEQ Pro’s high boost is very soft and silky, great for imparting a natural sense of “air” to an individual instrument or entire mix. Although not modeled after any single, specific piece of gear, SonEQ Pro’s high band takes inspiration from a variety of equalizers famous for their ability to impart a soft and silky sheen.
CUT (LP+HS, LP, LP-HS, HS): CUT control features four modes that variously combine low-pass and high-shelf.
- LP+HS: Combines low-pass with positive high-shelf. As low-pass is introduced, a high-shelf is coupled with positive gain, creating a slight resonance which results in the experience of increased mids.
- LP: A very musical sounding low-pass filter 6 dB / Oct.
- LP-HS: Couples a low-pass filter 6 dB / Oct with a simultaneously applied negative gain high-shelf.
- HS: High-shelf with negative gain.
High-pass: While the slope is highly effective for cutting, it’s the carefully sculpted attenuation near the slope that makes this filter especially soft and sweet.
Low-pass: The low-pass filter is a smooth 12 dB/oct, which combines two 6 dB/oct filters in cascade. Application of the filter results in soft attenuation of high frequencies recommended for restoration of a natural sound on the material which suffers from overhyped high frequencies.
When “Drive” is set to a value of zero, SonEQ Pro’s pre-amp section is designed to impartsubtle warmth without overt coloration of your mix. Round lows, warm mids, soft and natural highs, and enhanced perception of transients result from SonEQ Pro’s two-stage saturation.
The “Drive” control governs both the overall preamp saturation and also the saturation amount at the bottom end of the frequency spectrum. At a value of zero, saturation remains normal. Increasing the drive level will cause the drive knob to act as a low exciter, further saturating, and enhancing low frequencies.
