Thorens/Ortofon SPU124

The SPU 124 modernizes the classic SPU design with several optimizations designed for optimum compatibility to the new Thorens TD 124 DD. The SPU 124 features a revised generator system which allows for a maximum output of 0.5 mV, relaxing the requirement for high gain transformer or active preamplification systems. While still making use of a highly polished Nude Elliptical stylus, the stylus tip mass has been reduced significantly, resulting in reduced VTF and higher tracking ability. Specification Output voltage at 1000 Hz, 5cm/sec. - 0.5 mV Channel balance at 1 kHz < 1.5 dB Channel separation at 1 kHz > 23 dB Channel separation at 15 kHz > 15 dB Frequency response - 20-20.000 Hz ± 2 dB Tracking ability at 315Hz at recommended tracking force > 70 µm ( typical value ) Compliance, dynamic, lateral - 8 µm/mN Stylus type - Nude elliptical Stylus tip radius - r/R 8/18 µm Tracking force range - 2.5-3.5g Tracking force, recommended - 3.0g Tracking angle - 20° Internal impedance, DC resistance - 2 ohm Recommended load impedance - 10 - 50 ohm Cartridge weight - 30 g
