with Zero VTF when moving
VTA / SRA
The Gold Mongoose Tonearm is uniquely designed like no other tonearm. The Gold Mongoose Tonearm has zero tracking force when moving the VTA. That is what gives Expressimo Audio the ability to design a Arm pod that moves VTA / SRA with Remote Control giving you, in real time on the fly movement.
How you ask? Science and Geometry. There is another force that’s rarely talked about and that is the vector force. This is the rotation of the platter, the down force of the cartridge and the placement of the pivot point. When you have the pivot point above the platter your tonearm gets pushed up. Tracking force is lost in the groove. With the Mongooses Geometry there is no loss of tracking force.
Neutral balance means no zeroing of the tonearm. Mongoose doesn’t have a "see-sawing" affect. The Mongoose Tonearm always tracks in the perfect place in the vinyl. Now you will hear the right spatial ques, the right placement , space , depth, and air between the instruments. A center that will blow you away.
The main Effective Length is 11.950" × 25.4 = / 303.53mm
Mongoose Effective Length
How to go from mm to inches =
Stevenson - a variation on Löfgren geometry optimized for low distortion at the inner groove at the expense of increased distortion elsewhere. compared to Baerwald or Löfgren B you will get lower distortion for the last few mm of the record
Baerwald (identical to Löfgren A) - minimizes and equalizes distortion at the three weighted tracking error peaks resulting in moderate distortion between the inner and outer grooves
Löfgren B - minimizes distortion
between the inner and outer grooves resulting in the lowest average RMS
distortion at the expense of slightly higher distortion close to the inner
and outer grooves
REMOTE CONTROL VTA ARM POD AMAZING !!
Imagine sitting in the sweet spot with the power of a Remote Control that Controls your SRA, VTA Arm Pod with just a push of a button. Your eyes closed. Dial your SRA, VTA one thousands at a time up or down. Or hold down the button and keep moving to you find that sound.
Arm Pod has a dial indicator of accurate measurement.
Once you level the arm with Expressimoaudio tools you now have a zero point. Now move the SRA, VTA to where YOU like the sound. Now you can write down real numbers. Change to another cartridge and Level the arm. Now you can move the SRA,VTA where that cartridge sound good.
The OLD SCHOOL Manual VTA just can not compare to Expressimos REMOTE CONTROL ! It is not even close.
