AIR Music Technology – Stereophonic EQP v1.0.2.255 VST, VST3, AAX for Windows

• Iconic Pultec Tube Circuit Emulation: Faithfully reproduces the passive inductor filter networks and musical tube make-up amplification that defined classic analog tracking and mastering consoles.
• Advanced Spatial Processing Modes:
  • Stereo: Linked dual-channel equalization across left and right channels simultaneously.
  • Dual-Mono: Fully unlinked, independent parametric control over the left and right channels to correct stereo imbalances or sculpt wide acoustic instruments.
  • Mid/Side (M/S): Separate processing of the monophonic center (Mid) and stereo side information (Side) to focus low-end punch while expanding panoramic top-end air.
• Authentic "Pultec Trick" Interaction: Accurately simulates the non-overlapping frequency curves generated when simultaneously boosting and cutting low frequencies (20, 30, 60, 100 Hz), producing tight, focused sub-bass with an automated lower-mid clean-up notch.
• Flexible High-Frequency Shaping: Independent high-frequency boost bell with continuous bandwidth (Q) control alongside dedicated high-frequency shelf attenuation.
• Independent Channel Auditioning: Dedicated per-channel bypass switches allowing instant A/B comparison across individual stereo or M/S components.

• Seamless inMusic R2R Ecosystem Activation: Fully supported and permanently unlocked via the TEAM R2R System framework and INM810 inMusic Activator.

The Gold Standard in Musical Equalization
For over seven decades, the Pultec EQP-1A program equalizer has remained one of the most sought-after tone-shaping devices in the recording industry. Renowned for its passive filter network followed by a push-pull tube amplifier stage, the Pultec does not introduce the phase smear or harshness commonly associated with aggressive digital EQ curves. Instead, it imparts smooth, sweet, and musical frequency adjustments that flatter almost any audio source.

AIR Music Technology Stereophonic EQP translates that coveted analog behavior into modern DAW production. Rather than merely cloning the standard mono hardware layout, AIR adapted the core analog model specifically for the rigorous demands of contemporary stereo bus mixing and master-bus polishing.

Complete Stereo Field and Mid/Side Dominance
Vintage Pultecs were manufactured as mono, single-channel outboard racks, requiring engineers to match two individual units by hand for stereo sources—often resulting in minor channel offsets and phase discrepancies. Stereophonic EQP resolves this limitation by providing perfect stereo tracking alongside Dual-Mono and Mid/Side operation. Engineers can anchor kick drums and basslines tightly in the mono phantom center (Mid) while simultaneously boosting airy 16 kHz sheen on the stereo periphery (Side), creating a mix that sounds wider and more open without sacrificing low-end impact.

The Integrated Equalization Modules:

• 1. Low-Frequency Section (Low Band):

  • Selectable fundamental frequencies: 20 Hz, 30 Hz, 60 Hz, 100 Hz.
  • Boost: Variable gain adding deep fundamental weight and analog warmth.
  • Attenuate: Variable shelf cut designed to tame sub-rumble and low-end mud.
  • Simultaneous Boost & Attenuate interactions fully modeled after the hardware circuit.

• 2. High-Frequency Section (High Band):

  • High Boost: Selectable frequencies (3 kHz, 4 kHz, 5 kHz, 8 kHz, 10 kHz, 12 kHz, 16 kHz) with adjustable Bandwidth (Q) sweeping from broad, gentle slopes to focused curves.
  • High Attenuate: Dedicated high-frequency shelving attenuation (5 kHz, 10 kHz, 20 kHz) with depth control to smooth out harsh cymbals or brittle sibilance.

• 3. Spatial Routing Matrix:

  • Stereo Mode: Standard synchronized stereo operation.
  • Dual-Mono Mode: Completely decouples the Left and Right channel controls for asymmetric frequency correction.
  • Mid/Side Mode: Deconstructs stereo audio into Sum (Mid) and Difference (Side) paths for precision spatial equalization.

• 4. Output & Monitoring Stage:

  • Independent channel mute and bypass toggles.
  • Analog tube drive and saturation harmonics scaling naturally with input gain.
  • Master output trim and phase-invert controls.

In traditional equalizer design, boosting and attenuating the same frequency by identical amounts simply cancels out the change. However, because the original Pultec used separate passive circuits with differing curve slopes and slight frequency phase offsets for its boost and attenuation controls, dialing in both simultaneously produces a unique composite curve.

When you apply the Pultec Trick in Stereophonic EQP:

1. The low-frequency boost applies a broad resonant lift at the selected frequency (e.g., 60 Hz).
2. The low-frequency attenuation engages a shelf cut that begins slightly higher up the frequency spectrum.
3. The resulting composite curve produces a robust, tight low-end bump followed immediately by a gentle dip in the 200 Hz – 400 Hz range.

• Production Benefit: It injects punch into kick drums and bass guitars while automatically scooping out the muddy lower-mid buildup that often clutters busy digital mixes.

• Mastering & Mix Bus: Insert in Mid/Side mode across the mix bus. Lift 30 Hz on the Mid channel to firm up the center groove, while lifting 12 kHz or 16 kHz on the Side channel to widen spatial reverb tails and stereo synths.
• Drums & Percussion: Apply the low-end boost/cut at 60 Hz on the drum bus to give acoustic kicks and 808s a tight, focused transient punch without spilling into low-mid mud.
• Lead Vocals: Dial in a broad high boost at 10 kHz or 12 kHz to introduce silky, high-end "air" without bringing out harsh microphone resonances or piercing sibilance.
• Acoustic Guitars & Pianos: Smooth out percussive pick attack or boxy body resonances using the high attenuation shelf while retaining rich natural harmonics.

Frequently Asked Questions (FAQ):

• Q: How does Mid/Side mode affect mono compatibility?
  A: Because adjustments made to the Side channel cancel out completely when summed to mono, you can aggressively boost high-end sheen on the Side band without causing phase cancellation or altering the mono center vocal balance.
• Q: Why is the TEAM R2R System runtime required?
  A: inMusic plugins verify entitlements through local system calls. The R2R System framework intercepts and resolves these challenges locally, ensuring permanent offline activation.
• Q: Can I use this plugin alongside older AIR Creative FX plugins?
  A: Yes, Stereophonic EQP installs as a standalone modular effect and coexists alongside the AIR Creative FX Collection and modern AIR synthesizer plugins without conflicts.
