CBS Laboratories STR 100 Stereophonic Frequency Test Record

Lauded as the best audiophile LP test record and the ultimate tool to assess system performance. The STR 100, designed for the evaluation of pickups and systems was recorded with a constant velocity characteristic above 500 Hz. Tests include:

• Sweep Frequency - with sweep rate synchronized for use with a graphic level recorder
• Spot Frequency- includes voice announcements
• Channel Separation
• Wavelength Loss and Stylus Wear- pinpoints oversize or worn-out styli, and excessive pickup tracking force
• Compliance
• Phasing
• Vertical and Lateral Tracking
• Tone Arm Resonance- to check system performance at low and sub-audible frequencies and thus reveal undamped resonances which may cause system overloading
