Originally conceived for use in American’s consoles, this latest version is a continuation of the original 1967 equalizer with one additional filter band and several new frequencies. Incorporating American’s exclusive circuitry and proprietary components (such as the legendary 2520 op-amp), the A5B artfully blends the past with the present. Many eQs today offer a huge assortment of complex features, but the A5B provides exactly the right number of controls to the professional engineer.

Designed by the now legendary Saul Walker in the late 60’s, this discrete EQ was first used as a modular OEM equalizer. As the industry rapidly embraced the sonic quality of this unit, it quickly found it’s way into many custom console designs becoming the standard channel module EQ when the company began manufacturing consoles in 1971. The combination of Walker’s incomparable 2520 op amp and his “Proportional Q” circuitry give the user an uncomplicated way to generate acoustically superior equalization.

AQ550 3-Band Equalizer. The AQ550 faithfully captures the punch, low-frequency transparency, and ultra-tight imaging of iconic American EQs of the late 1960’s. Making use of Proportional Q intuitively widens the filter bandwidth at minimal settings and narrows it at higher settings without the need for additional bandwidth controls. This unique feature minimizes the «phase-shift» sound found in many equalizers. The AQ550 provides reciprocal equalization at 21 points in 5 steps of boost to a maximum of 12 dB of gain at each point. The 21 equalization points are divided into three overlapping ranges. The high and low frequency ranges are individually selectable as either peaking or shelving, and a band-pass filter may be inserted independently of all other selected equalization settings. Frequency ranges and boost/cut are selected by switches, and a pushbutton «IN» switch allows the EQ to be silently introduced to the signal path. A small toggle switch is used to insert the band-pass filter into the AQ550.

The Classic British And American Style Equalizer. An EQ plugin that combines classic inspirations into a modern powerhouse tool. ResQ integrates the smooth and robust shelving curves typical of iconic British equalizers with the precise, surgical mids of their American counterparts. The plugin boasts a versatile four-mode preamp section, capturing the essence of classic transformer and op amp designs, as well as both triode and pentode tube models. These modes enable rich, harmonic saturation that can either subtly enhance or significantly color your audio. Designed with musical frequency selections in mind, ResQ ensures that every adjustment is musically coherent, allowing instruments to seamlessly blend or stand out in a mix.
