of acoustical music, recorded in real space, to determine the tonal balance and soundstage presentation. Adjust the
tonearm pivot height upwards
5
1/6 inch at a time and listen to the changes. When the correct orientation has been
achieved, the soundstage will be better defined and the music will have a richer harmonic structure. Additionally, surface
noise will be reduced dramatically. If the soundstage comes into focus and becomes very lifelike, but the sound has a
slight hardness to the upper frequencies, the azimuth is probably misaligned (see azimuth section for adjustment details).
Azimuth:
For optimum tracking of the record grooves, the stylus must be in correct azimuth (side-to-side tilt)
alignment. Gross side-to-side tilt will result in an actual channel imbalance, but this is not a likely scenario. More
likely, any sort of an azimuth error that you will experience will result in tonal aberrations in the upper frequencies
and not a channel imbalance.
