Soundsmith SG-210 Strain Gauge System

Our SG-210 features both +15dB single ended variable outputs and fixed outputs. The +15 dB variable outputs allow using the SG-210 directly with your power amplifier, eliminating the requirement for a line amplifier in a vinyl playback system. They may also be used to match levels with other line sources in a multi-source system. The fixed level outputs may be used for recording or sourcing into a second system, and are not affected by the volume control. 

The supplied SG cartridge comes with the SG-5 stylus assembly as standard, however, you may purchase the system with the SG-6 stylus at the time of ordering. Like all SG preamps, the SG-210 features an auto-mute circuit that protects your system and speakers from transients due to an accidentally dropped styli. The front panel defeatable auto-mute also allows quiet introductions to playing or recording your vinyl.

All SG systems feature user replaceable styli, however, due to the nature of the cartridge design, styli are individually matched to each cartridge. If additional styli are desired, it is highly advisable to order them with your system order. The SG-210 is supplied in a black anodised case.

What is a Strain Gauge System?

A Strain Gauge System is a sophisticated technology used in turntables to read the grooves on vinyl records with exceptional precision. Unlike traditional moving magnet or moving coil cartridges, a strain gauge cartridge doesn't generate a voltage directly. Instead, it measures the microscopic deformations (strain) in a stylus or cantilever caused by the grooves.

This system typically involves a tiny, flexible strip called a strain gauge bonded to the cantilever. As the stylus encounters variations in the groove, the strain gauge deforms, and its electrical resistance changes proportionally. This change in resistance is then converted into an electrical signal, offering a highly accurate representation of the original audio.

One major advantage of strain gauge systems is their ability to capture details and subtleties in the music with minimal distortion, providing a more faithful reproduction of the recording.
