Audio-Technica AT618a(EX) – Disc Stabilizer / Record Weight
The Audio-Technica AT618a(EX) is a heavyweight disc stabilizer designed to hold vinyl records firmly against the turntable platter during playback. Weighing approximately 600g, it helps improve record-to-platter contact, reduce unwanted resonance and provide greater rotational stability. Its machined brass body is covered with protective rubber, giving the stabilizer a secure grip while helping protect records and turntable surfaces during handling.

Important Compatibility Note
Because the AT618a weighs approximately 600g, the connected turntable should be capable of safely supporting the additional platter and bearing load. Compatibility should be checked before use, particularly with lightweight turntables, suspended-subchassis designs or models whose manufacturer advises against heavy record weights. The AT618a is a stabilizer rather than a locking record clamp, so it works through mass rather than mechanical clamping force.

System Integration
The Audio-Technica AT618a(EX) does not connect electrically to the turntable or Hi-Fi system. It is simply placed over the centre spindle on top of the vinyl record during playback. Its 600g mass helps hold the record firmly against the platter and can reduce unwanted resonance. Because the stabilizer adds significant weight directly to the platter assembly, the turntable manufacturer's recommendations regarding record weights and bearing load should always be checked before use.
