What is it? A stereo, passive equaliser in a ‘500’ format with plug-in recall. Details Offering “pure analogue” signal paths with full digital recall facilities, the EQ 502P is designed to combine high-quality processing with the speed and convenience of preset operation. A Pultec EQ section employs shelving filters based upon “legendary” designs using matched stereo circuitry and featuring separate boost and attenuation knobs. Overall frequency response is quoted at 5Hz - 100kHz (-0.5dB) across a dynamic range greater than 106dB. The EQ 502P also boasts a signal/noise ratio of 104dB and a THD+N figure of less than 0.004%. Full digital recall is provided, with 399 memories reserved for users’ own presets. A USB link makes it possible to use the processor just as you would a plug-in (including Automation); there’s a free AU, VST, RTAS, AXX (32-bit and 64-bit) plug-in controller plus an A/B comparison function. And another thing… The design features steel screen isolators for maximum separation of digital and analogue sections.
