AT-CAP4

The AT-CAP4 is a versatile, two-sided turntable setup disc that enables you to adjust cartridge overhang, set cartridge offset and null points, and calibrate the platter speed.

The cartridge alignment side of the disc includes an overhang adjustment section that allows you to set the proper distance between the stylus tip and the turntable spindle (10–20 mm, according to your turntable’s specs). This adjustment is essential for ensuring proper tracking and minimizing distortion across the record’s surface.

• Versatile, two-sided turntable setup disc includes a side for cartridge alignment and overhang adjustment and a stroboscope side
• Cartridge alignment side of the disc includes null points for four different alignment geometries: Baerwald, Stevenson, Löfgren B, and UNI-DIN
• Stroboscope side of the disc calibrates turntable platter speeds of 33-1/3, 45, and 78 RPM at 50 or 60 Hz
• Proper cartridge alignment is crucial for optimal tracking, minimal distortion, and even wear on your vinyl records
