Description : The Trident CB 9066 digital equalizer is a software plug-in based on the original CB9066 and developed from the ground up by Trident Audio Developments. It is an accurate and easy-to-install software model of the famous equalizer.
The Digital Editions series from Trident Audio Developments embodies the very essence of what made the original Trident outboard gear classics of yesteryear: from warm tones and powerful sound to unrivaled richness, faithfully recreated for the digital world using a groundbreaking DSP engine and modeling techniques.
By fully utilizing this new signal processing technology, each Trident plug-in is among the most efficient and least resource-intensive plug-ins available today, meaning you can run multiple instances of Trident plug-ins simultaneously with minimal impact on your computer’s performance.
Parametric equalizer
The Trident CB 9066 is a 3-band parametric equalizer and combination high- and low-pass filters. It offers significant flexibility compared to conventional fixed-frequency or quasi-parametric equalizers, and is therefore not limited to a few predefined frequencies. With adjustable frequency, amplitude, and “Q” (quality factor) or bandwidth for the low, mid, and high frequency ranges, the CB 9066 allows the user to precisely tailor the audio signal.
Each of the three parametric sections can be individually disabled using the IN/OUT pushbutton switch. Each switch lights yellow when the section is in the IN position and active. When the switch is in the OUT position and the EQ section is disabled, the switch is unlit.
High and low pass filtering
As mentioned, the CB 9066 also includes high- and low-pass filters to further enhance audio signal processing flexibility. This is implemented in the form of a Sallen-Kay filter, precisely modeled using the modeling principle, with adjustable frequency (Hz) and slope (dB). As a result, the CB 9066 provides a maximum slope of 22 dB per octave, which can be turned off to varying degrees, thereby adjusting the overall slope speed (the frequency (Hz) is also adjustable).
The tilt adjustment ranges from 0/OFF to 22 dB per octave, allowing for both smooth and sharp cuts in the audio signal.
Overcorrection of the input signal
When using the CB 9066 plug-in, if significant adjustments are required by simultaneously boosting overlapping sections of the three parametric frequency ranges, attenuating the plug-in’s input signal may be necessary. This “overcorrection” may be necessary when using the device to simulate “phasing” effects, and can be achieved by using maximum gain in combination with a sharp “Q” and frequency range scanning.
Automatic gain compensation for sharp “Q”
Sometimes, with a given boost or cut amplitude at a given frequency, changing the response from a wide “Q” to a sharp “Q” results in a visible decrease in volume. This is due to a decrease in sound energy during the transition from a wide to a sharp “Q,” even though the amplitude remains constant. To overcome this effect, the CB 9066 implements automatic compensation, adding an additional 3 dB of gain at maximum gain with a sharp “Q.” This allows the user to focus on achieving the desired sonic result, rather than worrying about how to achieve it while compensating for the lack of output signal level.
