01 - Overview

What is PuTec?

PuTec is Babelson Audio's modern, low-latency digital recreation of the legendary Pultec program equalizer — the venerable analog hardware that shaped the sound of decades of professional recordings. PuTec faithfully recreates the classic program equalizer workflow and is designed for musical tone shaping on individual tracks and buses. It combines broad tonal moves, a signature high-frequency boost bandwidth control, and simple gain staging in one view.

Low Frequency Section

Selectable low frequency points with independent Boost and Atten controls for the classic low-end shaping behavior.

High Frequency Section

Separate high Boost and high Atten controls with independent frequency selectors.

High Boost Bandwidth

Adjusts the width/character of the high boost curve to move from broad to more focused top-end shaping.

Output and Utility

Output trim, bypass, oversampling options, metering, and integrated preset handling.

Note: PuTec processes stereo audio (2-in/2-out) and is intended for musical equalization rather than surgical correction.
02 - Installation and Activation

Getting Started

Install PuTec using your platform installer, then activate with your license account when prompted.

General Install Steps

  1. Download the latest installer package for your platform.
  2. Run the installer and choose plug-in formats required by your DAW (AU, VST3, AAX, Standalone).
  3. Launch your DAW and rescan plug-ins if needed.
  4. Insert PuTec on an audio track or bus.
  5. Open the activation panel from the lock/settings icon if activation is required.
Tip: If the plug-in opens in trial mode, save your project normally. After activation, your existing project settings are retained.

7-Day Trial Version

PuTec includes a fully-featured 7-day trial period — no credit card required. All features and processing capabilities are available during the trial with no restrictions or watermarking.

Trial Details:
  • Duration: 7 calendar days from first launch
  • Features: Full access to all PuTec controls, presets, and processing
  • No limitations: Works in all supported DAWs and plug-in formats (AU, VST3, AAX, Standalone)
  • Upgrading: Purchase a license anytime before the trial expires to continue using PuTec beyond the 7-day period

Activation and Licensing

PuTec uses the Cynicos License Management system for trial tracking and license activation. On first launch, the plug-in will either begin the 7-day trial automatically or prompt you to enter an activation key if you already have a license.

Important: When your 7-day trial expires, PuTec will require a valid license key to continue operation. Purchase a license at cynicos.com or upgrade through the Cynicos License Center application.

Preset Folder Locations

PuTec stores user presets in your Documents folder. Based on current implementation, the path is:

~/Documents/Putec

User preset configuration file:

~/Documents/PuTec/UserPresets.txt

03 - Interface

Interface Overview

The interface follows a single-panel hardware-inspired layout. All core EQ controls are always visible, with no hidden pages required for day-to-day operation.

Main Areas

  • Low section: Low Freq selector, Low Boost, Low Atten.
  • High section: High Boost Freq selector, High Boost, High Boost Q, High Atten Freq selector, High Atten.
  • Output section: Output trim control.
  • Global controls: bypass switch, oversampling selector, window size menu, presets panel.
  • Visual feedback: metering and status indicators.

Control Behavior

  • Knobs use vertical drag (up/down) for value changes.
  • Double-click a knob to reset to its default parameter value.
  • Most controls display popup values while editing.
  • Window size menu supports 100%, 125%, 150%, and 200% scaling.

05 - Controls

Controls and Parameters

The table below summarizes parameter ranges and defaults currently exposed by the plug-in.

Control Range / Options Default Description
Low Freq 20, 30, 60, 100 Hz 20 Hz Selects the low frequency target for low-end boost/atten shaping.
Low Boost 0.0 to 10.0 0.0 Increases low-frequency energy around the selected low frequency.
Low Atten 0.0 to 10.0 0.0 Attenuates low-frequency energy in the low section.
High Boost Freq 3, 4, 5, 8, 10, 12, 16 kHz 8 kHz Selects the center/target frequency for high boost.
High Boost 0.0 to 10.0 0.0 Applies high-frequency boost at the selected high boost frequency.
High Boost Q 0.0 to 10.0 5.0 Controls high boost bandwidth/shape character.
High Atten Freq 5, 10, 20 kHz 20 kHz Selects the target frequency for high attenuation.
High Atten 0.0 to 10.0 0.0 Applies high-frequency attenuation at the selected high atten frequency.
Output -20.0 to +20.0 dB 0.0 dB Final level trim after EQ processing.
Oversampling x1, x2, x4, x8, x16 x2 Raises internal processing rate to reduce aliasing in non-linear stages.
Bypass On / Off Off Disables plug-in processing and passes audio through.

Classic Low-End Interaction

The low Boost and low Atten controls can be used together to create the well-known broad low-end contour. This is especially useful for adding weight while preserving clarity.

Tip: Start with small moves (1.0 to 3.0) and level-match with Output before judging tonal changes.
06 - Workflow

Workflow and Use Cases

Use these settings as starting points, then adjust by ear to match your source.

Vocal Air and Clarity

  • High Boost Freq: 10-12 kHz
  • High Boost: 1.5 to 3.5
  • High Boost Q: 4.0 to 6.0
  • Optional High Atten Freq: 20 kHz, High Atten: 0.5 to 1.5

Bass Weight Without Mud

  • Low Freq: 30 or 60 Hz
  • Low Boost: 2.0 to 4.0
  • Low Atten: 1.0 to 2.5
  • Adjust Output down to keep loudness matched

Mix Bus Tone Polish

  • Low Boost: 0.5 to 1.5 (30 or 60 Hz)
  • High Boost: 0.5 to 1.5 (10 or 12 kHz)
  • High Boost Q around midpoint for smooth top-end lift
  • Use bypass toggling frequently for objective A/B checks
Warning: Broad boosts can increase perceived loudness quickly. Level-match with Output to avoid biased decisions.
07 - Presets

Presets

PuTec includes 20 factory presets for common instruments and starting points.

Default Vocal Male Vocal Female Rock Vocal Acoustic Bass Electric Bass Bass Synth Rock Bass Electric Guitar Rock Rythm Guitar Piano A Piano B Keyboard Strings Snare Tom Medium Tom Floor Hihat Ethno Drums Percussions

User Presets

Save custom presets from the preset component and organize them in your user preset folder:

~/Documents/Putec

Tip: Use factory presets as tonal templates, then adjust the selected frequency points first before changing gain amounts.
08 - Metering

Metering and Gain Staging

PuTec provides input and output level tracking to help you maintain clean gain structure.

  • Watch both input and output levels when pushing boost controls.
  • If output level rises significantly, reduce Output trim before comparing bypass states.
  • Use oversampling for cleaner behavior at stronger settings when CPU budget allows.
Note: Proper level matching is essential when evaluating broad EQ moves, especially on full mixes.
