SERIES 312 S
SERIES 312 S
The Raime SME 312 S is an evolution of the 312 model. The tonearm tube on the 312 S is made of magnesium. The headshell is removable and also made of magnesium. The counterweight is made of a tungsten alloy and is suspended to achieve optimal center-of-gravity distribution. Tracking force is adjusted using an Allen screw located in the counterweight housing. The two-piece base allows for adjustment of both the vertical tracking angle (VTA) and the horizontal tracking angle (HTA). The 312 S features fully adjustable FD-IV damping.
Key
Features of the 312 S
Unique tonearm tube design, extruded entirely from magnesium alloy, just like in the V model
The inner surface is coated with a special compound that dampens any residual vibrations that may arise within the arm’s structure itself.
The meticulously machined surface of the magnesium alloy head platform prevents resonance at the point of contact with the cartridge.
A stainless steel spindle with 10-mm ABEC-1 ball bearings mounted on it. The entire assembly is supported by a solid yoke and positioned at the same height as the platter surface, which effectively prevents sound distortion.
A unique assembly method for individual components that ensures high rigidity and guarantees a precise fit of the bearings even before the entire arm is assembled.
The vertical bearing shaft is made of stainless steel and features an integrated 16-mm-diameter flange that connects it to the yoke.
A 23-millimeter-diameter vertical bearing housing made of hardened steel, with a pair of 17-millimeter ball bearings installed. The bearings are widely spaced to prevent the arm from tilting.
A lift that allows for precise lowering and raising of the needle from the surface of the plate. Its range of operation can be adjusted.
A two-piece base that provides high rigidity and enables precise control of arm movement.
The ability to adjust the tonearm height (VTA) using a screw located in the tonearm body.
A counterweight made of a tungsten alloy, supported at two points and damped. Its special low-inertia design reduces the impact of eccentrically machined plates on the insert’s operation.
The swivel output connector allows for optimal routing of the signal cable. This design also minimizes the transmission of vibrations to the subchassis.
Precisely marked horizontal lines on the arm tube make it easier to adjust the arm to the correct height.
A special template makes it easy to set the optimal horizontal reading angle.
The tool included in the set makes it easy to install the tonearm on any turntable.
