The Strain Gauge

 patents pending

 

 The Strain Gauge cartridge is not at all like any other cartridge.

 All other cartridges, whether moving magnet, moving coil, or moving iron, are "generators" - that is, you put motion in, and you get energy out... a tiny voltage that you amplify and send to your speakers.

 The key here in describing all other cartridges is in the word moving.

  All other cartridges need to move a mass around - a mass that is attached to the stylus and cantilever.....either a magnet, an iron core with wires (moving "coil") or a piece of iron.

 They are all magnetic generating systems, which require a mass to be constantly moved to generate a voltage. In the Strain Gauge, this mass has been all but elimianted, allowing the stylus to move much more quickly, therefore staying in intimate contact with the groove walls......

Specification:

  • Frequency response, DC to 70 Khz (rumble filter at 12 Hz.)
     

  • No "RIAA" filter multi-stage preamp circuitry is required or used in our preamp - We have just one ULTRA clean gain stage between you and your music          (RIAA compensation IS required for "velocity" sensitive magnetic cartridges - The Strain Gauge is a "displacement" device......which automatically compansates for the RIAA EQ, thus allowing for an elegant, ultra clean preamp design - the "Less is More" audio philosphy....)
     

  • Compatible with standard "4 wire" tone arm wiring - no special wiring required

  • User Replaceable stylus assembly - automatically aligns when insterted (varied styli types available) - a feature unheard of in high end cartridges
     

  • System Price includes Strain Gauge Cartridge and Soundsmith SG Preamp model of your choice
     

  • All models feature "Fixed" Line level outputs AND +10dB variable outputs (controlled by front panel volume control); all outputs are Balanced and Unbalanced via RCA jacks for maximum hookup options -
     

  • High Compliance design and freedom from low frequency saturation assures excellent tracking ability and compatability with any tone arm
     

  • All models feature touch-switch toggling between the Strain Gauge function and single or (multiple) line inputs for maximum hookup flexibility to your equipment
