Cartridge setup | How to check & adjust Azimuth

- Azimuth adjustment or vertical alignment of the cartridge is very important for optimal channel separation. The checking is easily done by lowering the cartridge onto a thin mirror placed on the record surface and examining whether the reflection lines up square with the cartridge, when viewed from the front. During this test tonearm must still be parallel to the record surface. If not obtainable because of mirror thickness, remove record and work directly on the mat. If alignment is still incorrect and not adjustable because of fixed headshell, the only solution is to resort to packing on one side of the head-shell.

Always remember that cartridges are extremely delicate devices. Absolute care and attention must be given when installing your cartridge to avoid any accidental damage.

Very clear instructions and the macro video shooting really helped me understand what I need to do. Thanks!
this is very critical adjustment. This determines the stereo separation. The mirror is a good idea. I have seen USB cameras made for this adjustment. It's so hard to see that little stylus
Using a first surface mirror where the reflective coating is on the front instead of the back can help you see the alignment a bit better. Such mirrors are available online and are not too expensive.
Thank You. I have a Ortofon 2M Blue. My Azimuth needs adjustment. Without a mirror I can see it's off. Love the suggestion of using shims to get it right if needed. What is important is to get that needle perpendicular, going into the groove straight. I'll work on it.
It would have been helpful if the instructor had actually loosened the head shell and placed the shim appropriately. Of course, we can all figure out how to do it, but seeing a skilled person show how it is done would add to the confidence of a user doing it for the first time. Otherwise, excellent demonstration.
You can also rotate the tone arm their is a screw on there but. This way is easier.
Wonder why they didn't point that out...this looks like a debut carbon - their own product - which has that screw for adjustments.
If the adjustment isn't correct. Would this cause a new record to stick at the start of tracks?
I don't know if that is correct. If the azimuth is not set correctly, shouldn't we also be able to hear that one channel is quieter or louder than the other?
merci , mais il faut regarder avec le gabarit A&b voir si l'aiguille est correct donc compliquer de passer de l'un a l'autre
I have an OM-Blue and i love it. However the oblique form of the element does not make any adjustment easier.
Yesss
I'm not sure that is correct to have it at 90 degrees !
when they cut the record the cutting head is not at 90 degrees because they got to remove the material far as I know and what that angle is when they are cutting??
You’re thinking of stylus rake angle.
@@utub1473 yeah you're right
@@hoobsgroove Anyway, most people recommend 92 degrees for that. All cutting lathes are different, but they fall into a range of 91-93 degrees.
@@utub1473 depends dynamic or static measurement? I would say static 88.5° - 89.5° would be better
There's actually a grub screw at the rear of that tone arm that allows the arm to rotate to adjust azimuth. No shims needed. I just checked mine, and that's the story of why I'm here.
I don’t understand why you would have to pack one side or the other. My Pro-Ject table allows me to adjustment azimuth by rotating the tone arm after loosening a screw.
What table do you have?
Azimuth is defined as a horizontal angle. You're describing the complete opposite, a vertical angle. Please explain.
My guess is that although you are looking at the vertical stylus, the angle you are adjusting is the horizontal angle of the top side of the cartridge
While "azimuth" traditionally describes a horizontal angle, its application in vinyl records is a specialized usage that reflects the need for precise angular alignment, albeit in a different plane (vertical rather than horizontal). This adaptation of the term is considered correct within the context of audio engineering, despite the difference in the plane of measurement.
They have reasonably cheap tools for this;wherein it's a vertical plastic see through plate with horizontal lines. You use the lines to see if your cart bottom is parallel to your record surface. But this assumes that you diamond tip is glued exactly perpendicular to your cantilever. Many are not. Only way to get this perfect is with a microscope and a software program. The more you learn about carts, the more bogged down into details you become. Using your eyes like this is only going to catch egregious misalignment. In addition, Ideal VTA is 92 degrees and you can't do that with your eyes. Most folks align carts with their ears. That can only take you so far.

these cartridges are the biggest pain to align
i bought one these needles sounded awful
kann man des nicht auch auf deutsch bringen oder glaubt ihr jeder ist der englischen Sprache mächtig
This is nonsense
