The third generation of optical cartridges from the Japanese company\u00a0DS Audio<\/b>\u00a0features a completely redesigned optical system that has been optimized using independent LEDs and photodetectors for the left and right channels.\u00a0As a result, the output voltage of the cartridge has increased significantly from 40 mV to 70 mV.<\/p>\n

At the same time, the signal-to-noise ratio for which\u00a0DS Audio<\/b> optical cartridges are famous has not deteriorated. In addition, the new independent design of the DS Audio DS003<\/b>\u00a0cartridge\u00a0has<\/b>\u00a0eliminated crosstalk, significantly improving left and right separation (in particular, high frequency separation is 10 dB better than previous models).<\/p>\n

The weight of the new redesigned beryllium shade plate has been reduced by 50%.\u00a0The implementation of independent LEDs for the left and right channels allowed for optimization of the positioning of the optical system, but also necessitated the use of a new dimming plate, which is significantly reduced in size compared to earlier designs.\u00a0In addition to this size reduction, the material used to make the shade plate has been changed from aluminum (which is used in second generation cartridges) to 99.9% pure beryllium.\u00a0As a result,\u00a0DS Audio was<\/b>\u00a0able to reduce the weight of the shade plate by more than 50% – from 1.56 mg to 0.74 mg.<\/p>\n

\"DS<\/p>\n

The\u00a0DS Audio DS003 cartridge<\/b>\u00a0is a combination of an aluminum cantilever and a line contact sharpened needle.\u00a0The head body, made of aluminum, is designed to provide maximum structural rigidity.\u00a0In addition to these features, the\u00a0DS003<\/b>\u00a0uses internal wiring 1.6 times thicker than second generation cartridges to reduce resistance.<\/p>\n

Compared to the\u00a0DS Audio DS002<\/b>\u00a0equalizer, the\u00a0PCB<\/b>\u00a0thickness has been increased from 1.6 mm to 2.0 mm, and the copper foil thickness has been changed from 35 \u00b5m to 70 \u00b5m.\u00a0In addition, the\u00a0DS003’s<\/b>\u00a0equalizer\u00a0allows\u00a0you<\/b>\u00a0to select the cutoff frequency for the low frequency range from four values.<\/p>\n
