Passive Tube Equalizer with Optional Linear Phase Correction

Pulsar MP-EQ is a detailed emulation of a world-renowned analog mastering equalizer, redesigned for modern workflows. It reproduces the original passive circuitry, inductors, and tube/transformer stages while introducing an optional Linear Phase Correction mode — a first for this type of EQ — ensuring precise phase alignment across the spectrum.

Key Features :

- Linear Phase Correction (New):

In traditional analog and emulated EQs, different frequencies are shifted in time due to the natural phase behavior of the circuit.?MP-EQ adds a unique process that can realign all frequencies after equalization, transforming an analog-style EQ into a true linear-phase processor.

• Preserves transient accuracy with no temporal smearing.
• Restores clarity and punch in the low end by maintaining harmonic alignment.
• Ideal for EDM, mastering, and any material where waveform integrity and phase coherence are critical.
• Prevents asymmetrical artifacts in Mid/Side mode by maintaining proper alignment between channels.

- Analog-Modeled Passive Equalizer:

MP-EQ accurately models every component of the original hardware:

• Passive parallel topology — bands interact naturally rather than stacking, resulting in smooth, musical corrections.
• Inductor-based filters — provide organic saturation and subtle low-end compression due to magnetic behavior.
• Tube and transformer gain stages — add gentle harmonic coloration and warmth.

This design produces an intuitive response and a natural tonal balance even at extreme boost or cut settings.

- Interface and Controls:

• Curve Editor and Spectrum Analyzer – Edit the EQ response graphically and visualize the spectrum in real time.
• Drive Control : Adjust internal level to increase or decrease tube and transformer saturation.
• Mid/Side Processing : Independently shape mono and stereo information, with solo and visual monitoring for each channel.
• Auto-Gain – Compensates loudness changes introduced by EQ using an intelligent, curve-based algorithm.
• Transformer Selection : Choose between three output transformer modes:
• Original : faithful to the hardware circuit.
• Colorful : enhanced low-end warmth.
• Clean : transformer stage bypassed.
• Oversampling : Switchable processing rates up to 384 kHz for higher-precision rendering.
• Resizable Interface : Scales smoothly from compact to large-format display.
