Pulsar Audio MP-EQ

Pulsar MP-EQ

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.

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.
