Comprehensive Calibration Tools Included for Optimal Turntable Setup
The WT-2 Laboratory Edition includes a suite of resources and test tracks for perfecting every detail of turntable performance:
- Detailed Arm Calibration Guide: A five-step, illustrated guide assists users in aligning their turntable tonearm. This guide covers every aspect of setup, from stylus tracking angle (VTA) to azimuth, alignment, cartridge pressure, and anti-skating, making it accessible for both advanced users and newcomers alike.
- Precision Anti-Skating Calibration Template: Tracks are provided for exact anti-skating adjustments, designed to account for groove friction accurately. Users can rely on this template to correct and stabilise the tonearm, reducing distortion for an uncoloured sound profile.
- Two Black Vinyl Records: Each record features expertly designed test tracks on sides A through D, covering all key calibration signals and measurements required for optimal turntable setup.
Side A and B: Frequency Response Tests and Anti-Skating Validation for Unmatched Playback Accuracy
- Frequency Response Testing (Side A): Tracks deliver a range of frequency sweeps from 20 Hz to 20 kHz with varying levels, allowing users to analyse cartridge characteristics across the audio spectrum. These tests are critical for balancing the cartridge output and achieving high signal-to-noise ratios.
- Anti-Skating and Isolation Testing (Side B): Featuring a flat surface to validate anti-skating adjustments, side B also includes a silent groove track that aids in turntable isolation assessment, minimising vibrations and enhancing playback clarity.
Side C and D: Advanced Wow and Flutter Calibration and Anti-Skating Testing for Precise Tone Control
- Wow and Flutter Signal Tests (Side C): The 3150 Hz test tones on side C allow dynamic speed variation assessments to ensure consistent playback speed. This helps in fine-tuning speed stability and detecting irregularities that may otherwise affect playback quality.
- Cross-Channel Crosstalk Measurements and Anti-Skating Tests (Side D): Tracks enable in-depth crosstalk testing, helping verify that the stylus remains correctly positioned within the groove. The test tracks with out-of-phase signals are also effective in identifying distortion, imbalance, and phase issues.
Additional Features for Audio Enhancement and Protection
- Step-by-Step Video Tutorial: Unitra offers a detailed instructional video to assist users with the setup process, ensuring ease of use and precision during calibration.
- Maintenance Recommendations: Regular maintenance is essential for sound quality preservation. The WT-2 recommends pre-playback dusting with an anti-static brush and stylus cleaning before and after use, safeguarding both record and stylus longevity.
The WT-2 Turntable Test Vinyl Record - Laboratory Edition brings unparalleled audio calibration potential to audiophiles, helping them achieve an elevated listening experience by optimising every playback parameter to perfection.
