A lightweight aluminum die-cast headshell for standard half-inch, four-pin cartridges. The AT-HS10BK uses a universal H-4 bayonet connector, so it drops into any S-shaped or J-shaped tonearm built to that standard — Audio-Technica specifically lists the AT-LP120-USB and AT-LP1240-USB. The die-cast aluminum body is chosen to keep vibration to a minimum without adding mass. Its finger lift sits well forward for precise cueing, and the cartridge mounts in slotted through-holes so you can slide it fore and aft to set overhang. Gold-plated lead wires and all the mounting hardware are in the box, so it is ready for a cartridge straight away.
