Correct overhang length and cartridge alignment is critical to
obtaining proper audio reproduction without distortion and avoiding
unnecessary record and stylus wear. Aligning a cartridge is a precision
task and cannot be done properly by eye or guess work alone.
Over the years of developing turntables and testing various arm configurations, AVID
developed a computer program to calculate optimum alignment, taking
into account the tonearm's correct geometry. This has lead to the
release of the AVID Alignment Gauges. These protractors offer
high precision alignment capability, placing the stylus exactly where it
should be for the best sound, longest life and lowest distortion.

Every radial tracking arm has its own "null points" or areas where
distortion is zero, it is very important to align the cartridge to these
points for optimum tracking, channel balance and record wear. The Universal Alignment Gauge works with most tonearms and allows a very high degree of setup accuracy. For the three most popular tonearms used on AVID turntables, Rega, SME & Linn, AVID developed tonearm specific Alignment Gauges. These tonearm specific models offer 100% precision alignment, in a quick, accurate and repeatable manner.
The mirrored surface of the Alignment Gauge makes all
measurements easier and more accurate. The mirror's parallax effect
helps eliminate sighting errors and provides better lighting which is
critical in making fine adjustments on small parts. The two null points
on the specific alignment tools are surrounded by parallel lines, making
cartridge body alignment (both front and rear) very precise. The long
"tail" alignment line is extended so that the stylus itself can be
checked and aligned in case of cartridge manufacturing errors.
