Professional-Grade Turntable Calibration

The Unitra WT2 Test Record Laboratory Edition is an essential diagnostic tool for achieving optimal turntable performance. Designed for audiophiles, vinyl collectors and hi-fi technicians alike, this precision test record helps you calibrate and fine-tune every aspect of your turntable setup — so you can extract the very best possible sound from your analogue system. Achieve reference-quality vinyl playback through precise, repeatable calibration.

Every Calibration You Need on One Disc

The WT2 covers the full setup workflow. Precise test tones enable accurate cartridge alignment, stylus positioning and azimuth adjustment. Stroboscopic patterns let you verify 33⅓ and 45 RPM speed accuracy. Dedicated tracks help you optimise tracking force for your specific cartridge, confirm equal output through a channel-balance test, and fine-tune anti-skate force for proper, distortion-free tracking.

Laboratory-Edition Precision

As the name suggests, the WT2 is a professional-grade pressing engineered for reliable, repeatable results — the kind of consistency a technician needs when servicing a deck or an audiophile wants when dialling in a new cartridge. Whether you're a seasoned listener or new to vinyl, the WT2 ensures your turntable is performing at its absolute best.
