Grado DJ200 Stylus
Grado DJ200 DetailsGrado Labs announces the release of their new DJ series of professional phono cartridge. Built and designed to meet the demanding needs of the professional DJ musician, these cartridges deliver performance never known before in the pro DJ market. The Grado specially engineered transmission line cantilever allows for the ideal transfer of music signal and for safe and effective stylus back-cueing. The DJ series can track from 2 to 5 grams, and delivers the warm musical Grado sound the audio industry has embraced and enjoyed for 50 years. The DJ series incorporates our newest Flux-Bridger generator systems for lower effective tip mass and lower electrical inductance. Each DJ series cartridge is hand assembled to Grado's high standards, which contributes to the unchallenged consistency of performance, and the Grado guarantee of reliability. The DJ series of cartridges are the most advanced phono pickups ever offered to the professional DJ market, without exception. Cartridges are packed by themselves. Stylus replacements are packages with two replacements. The Prestige model DJ200 uses a modified four piece OTL cantilever technology, oxygen free wire in the coils and a specially designed, high polished, diamond mounted in a brass bushing.
Optimized Transmission Line (OTL) Cantilever/Stylus AssemblyGrado's OTL provides an ideal transfer of the signal from point to point, e.g., stylus to cantilever to magnet to coils, etc. This has been achieved by eliminating resonance at each of these key junctions. The transmission line cantilever consists of separate sections that are telescoped into each other. All sections are made of different alloys, some sections hollow, other sections solid. These sections are bonded together with materials that act as dampers, and are coated with a black proprietary material which controls and absorbs resonances that travel on the surface of the cantilever (known as skin effects). The OTL stylus/cantilever design will make your records sound quieter, improve the height, width, and depth of the soundstage, and offer more detail than previously obtainable. Cartridge Holography does exist...and that is what Grado's OTL technology is all about, more performance.
Pivoted-Fixed Axial Cantilever/Stylus GeneratorThis design feature is basically quite simple. The "OTL" cantilever shaft is brought to a fixed axial pivot that supports the entire cantilever assembly. A miniature element attached to the end of the cantilever is allowed to move freely within the lines of flux of a stationary magnet and coil structure. This system of support is mechanically more accurate (more linear) than conventional "teeter-totter" designs that utilize an iron armature to balance the mass of the cantilever. The teeter-totter design is supported in the center with a rubber donut mounting. The fixed axial design has a very low tip mass, which results in lower distortion, improved transient response, and longer record life.
