Tonearm microphonics


When I have the volume at my normal level & tap the arm (not whilst playing vinyl) it is slightly amplified... Is it possible to significantly reduce/eliminate this?

Current set up - Roksan Xerxes 20plus, Origin Live Encounter tonearm (thin cork ring at the base) with Lyra Skala.

Apologies if this is a stupid question!

You could just do nothing and enjoy the high quality sound reproduction you already have.

By touching the arm you are causing the so called ''ground loop''.

There must be something wrong with either your phono-cable

or the tonearm ground. I own + 40 carts with no hum problem

at all except by my most expensive cart; the Allaerts MC 2 gold.

The problem must be in the cart but by Expert Stylus in UK they

were not able to discovere anything wrong with the cart. No

wonder nobody knows how and why hum problem arise and

conseqently how to get rid of it. ''Trying'' is the only advise one

can get.

Dear @infection : What you are listening is totally normal because that tonearm has mounted a very sensitive microphone in that Skala cartridge ( or any cartridge, it does not matters. ) that when we tap a tonearm we can have that kind of tiny " sound ". Nothing wrong with that.

Now, the level of that tiny sound  is different from tonearm to other one depending on the tonearm overall design and how well is dampening it self and of course the cartridge model.

Any one of us can test it and in more or less way we can have that experience. Maybe in some systems the system volume needs to be higher than in others and depends too where we tap/hit the tonearm.

Now, if you are satisfied with what you are listening in your LPs just forgeret about and enjoy what you have.


Regards and enjoy the MUSIC NOT DISTORTIONS,

This is so funny Raul keeps coming up with these funny theories that aren’t even remotely related to reality yet he portrays himself as an expert in Music Reproduction Systems and especially phono playback. A phono cartridge is not a microphone! A microphone converts sound to an electrical signal by employing the use of a diaphragm. A cartridge is actually a tiny electrical generator that uses a stylus/cantilever to create the signal using a magnet and coil and the stylus/cantilever is excited NOT by sound but by the motion of the stylus/cantilever in the record groove! These are two different things! You do not want your phono cartiridge to be "microphonic" because that signal can interact and distort the intended signal! That is why they call it "microphonic" because it is acting like a "microphone" which is not what you want the cartridge to do. A microphone is designed to reproduce sound and a quality phono cartridge is designed to NOT reproduce sound but only the signal that is in the groove which is not "sound" it is little wiggles in a groove. Raul your theories are amusing but they are almost always wrong wrong wrong.
