With a specialized body and internal wiring dedicated to monaural sound reproduction, the VM610MONO conical stylus cartridge is designed for playing mono records. Part of the 600 Series in Audio-Technica’s new VM cartridge line – a line that harks back to A-T’s early days as a manufacturer primarily of high-end phono cartridges – the VM610MONO is equipped with dual magnets that are internally connected to reduce record noise and obtain a highly focused “center” sound image that stereo cartridges can’t provide.
