The 192-44-7/DJ IMP SD is a replacement stylus that can be used with the Shure M44-7 record cartridge. It is not an original stylus manufactured by the manufacturer, but has the same performance as the original stylus. This product has a heavier recommended stylus pressure than the standard type (192-44-7 IMP SD) to withstand the hard scratching that occurs during DJ play. This replacement needle is a "synthetic diamond round needle" type. This is a general-purpose model with a standard conical shape that reproduces a general range of sound. The typical lifespan is about 200 hours. [Product Specifications] JICO No: 192-44-7/DJ IMP Format: MM Tip shape: Synthetic diamond round needle Stylus pressure: 3.5-4.5 Compatible cartridges: IMPACT, J44A 7, J50, M44-7 [Precautions for use] The "general lifespan" listed above is only a guideline. Even if the actual usage time is less than the "general lifespan," it may still be unusable due to factors such as usage conditions (such as using a needle with pressure other than the specified level or in a dusty environment) or deterioration over time. [Product and other precautions] Please be careful when handling the record, as touching the tip of the stylus will not only prevent it from working properly, but may also cause injury. Please note that product specifications, standards, and appearance, such as knob color, may be changed without notice for improvement purposes. Store record needles and accessories away from direct sunlight, high temperatures and humidity, and out of the reach of small children.
