CONTROL THE BEAST
Ask an engineer for a shortlist of EQs that make their eyes and ears sparkle, and they’ll probably mention an inductor-based design with a nautical name that conjures up images of the god Poseidon. The EQ section of this rare and legendary console made the sound of records you might have grown up with: Queen, The Beatles, David Bowie, The Rolling Stones… Let’s just say it’s “tried and tested”.

Present in very few studios, this console is renowned for being highly musical. One key component behind its mojo is its unique band interactions – pushing the gain of one band can lead to EQ curves that would need three or four bands on a parametric EQ.

With such an idiosyncratic EQ, there’s a learning curve. The interactions between its bands are so unique that we’ve never seen a digital reproduction that makes them simple to use. So we decided to nail it ourselves with an on-screen EQ curve that reacts faithfully to the quirks of the original hardware, making Pulsar Poseidon easy to master.

With all its additional features (Mid/Side bands, Gain Scale, Auto-Gain, multiple saturation colors), this plugin (VST/VST3/AU/AAX) faithfully resurrects the rare and iconic qualities of this console EQ into the digital realm.

Main Features
Topology Preservation Technology
Our modelling technology guarantees a perfect emulation of the original device’s behavior. From the saturation of diodes, transistors or tubes, to the slight internal filterings, to the tiny calibration defects, everything is perfectly reproduced. What’s more, we can reproduce all these behaviors without going through a complete simulation of the circuit, thus saving CPU power.

Saturation stage
Push the signal further with one of two saturation circuits and adjust the processing strength using the Drive knob. The first mode faithfully emulates the analog circuitry of the console that inspired this plugin, while the second is a Pulsar Audio creation featuring a slightly more modern and aggressive character.

Modern EQ Edition
Manipulate a peculiarly shaped analog EQ curve in an intuitive way. The curve editor is extremely easy to use, with a clear and concise overall frequency response display. You can edit all properties of any filter without touching the lower panel.

Output Transformer
The analog circuit of the original console channel had no output transformer. Pulsar Poseidon offers two additional options: an output transformer inspired by the Marinair models used in old Neve preamplifiers, and an original transformer algorithm optimized for the enhancement of low-end harmonics.

Mid-Side processing
Each band can be used on the entire stereo signal, or switched into operating with a single focus: the Mid only, to process monophonic, centered audio or the Side only, to process stereo, non-centered audio.

Auto-gain
This control compensates for volume changes introduced by equalization, keeping output level consistent with input. It uses a C-Weighting-based algorithm to introduce a level compensation based on EQ curve analysis. The compensation gain applied only depends on your EQ settings and won’t change during playback.

Metering & Spectrum analyser
The on-screen analyzer displays the audio spectrum in real-time (fast and slow window settings) or over the long-term with the Infinite Spectrum setting. In addition, peak metering provides insight into overall dynamics, and RMS meters let you monitor loudness and level matching. An overall gain meter is also available.

Gain scale
For wholesale reduction or increases in gain, the Gain Scale control lets you accentuate or reduce an entire EQ curve, acting like a multiplier for all bands’ gain settings.

Oversampling
A selectable oversampling mode is available for computers that can handle it, with processing at rates up to 384 kHz. You can choose for higher oversampling settings to be applied at export than at playback.

Smart GUI
Pulsar Poseidon comes all wrapped up in a responsive and resizable interface. A resize handle enables you to choose the perfect size for each use case, from nice and compact to highly visible.

System Requirements
macOS 10.11 or newer
