Optimum Load: 47,000 ohms resistance in parallel with 200 to 300 picofarads capacitance
per channel. Load resistance can be up to 70,000 ohms with almost no audible change in
frequency response. Total capacitance includes both tone arm wiring and amplier input
circuit.
Certication: Conforms to European Union directives, eligible to bear CE marking; meets
European Union EMC Immunity Requirements: EN 50 082-1, 1992.
Net Weight: 7.3 grams including standard 1/2 in. mounting adapter. Without adapter,
cartridge is compatible with pre-set P-Mount arm.
THiS CaRTRidGE FEaTURES THE SHURE BiRadiaL NUdE diaMONd Tip
Its contact area is longer and narrower
than the traditional spherical tip-groove
contact area. This results in dramatic
reduction of both harmonic distortion
and inter modulation distortion.
To clean the stylus, use a soft brush
with alcohol or an alcohol-distilled
water solution. Brush only from back to
front as shown. Commercial cleaning
solutions may cause stylus damage.
