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:

MPEQ 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 that 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.

Typical Applications:

• Mastering: Add depth, clarity, and smooth top end with precise phase alignment.
• Mix Bus: Shape overall tone without introducing unwanted phase shifts.
• Vocals and Instruments: Use the bandwidth control for focused midrange or warm low end tone.
• Electronic Music: Maintain punch and waveform integrity in bass and synth material.
