Goldring E1

The Goldring philosophy is to promote the accurate replication of the original record production, maintaining the creative nuances, musicality and rhythm the artist intended you to hear. With the versatile E Series, this is easy to achieve; each is designed to be simple to fit to the majority of budget to medium priced turntables.

The E1 cartridge, the first in the range, utilises a carbon-fibre reinforced cantilever and bonded, spherical (0.6 mil) stylus with a round shank. Carbon is an effective alternative to more premium aluminium or boron materials, producing comparable results in most entry level hi-fi applications.

Features

Magnetic Duplex Technology™

All cartridges in the range feature Magnetic Duplex Technology™-a 'dual magnet' generator assembly with an identical geometry to that of the original cutting head. This means it can more accurately reproduce the stereo information in the record groove, providing better channel separation and a more involving and musical sound stage. 

Expert Adjustment

The E-series cartridges have been designed to allow micro-adjustments to be made during production using a special adjustment screw. This means the cartridge can be safely installed in a typical turntable because the angle that the stylus makes with the record surface has been pre-set. The result is an optimized channel balance with zero degrees of horizontal tracking adjustment required. This ensures a consistent and reassuring performance for the life of the product. 

Stylus/Cantilever

Featuring spherical styli with a choice of cantilevers, the E1 and E2 models are ideal as an upgrade to any budget, pre-fitted or obsolete cartridge. The E3 model with its re­fined super elliptical stylus is a worthwhile upgrade for those wishing to squeeze even more information and detail from the record groove.

What is a Moving Magnet Cartridge?

All transducers of this type depend on Faraday's Law of electromagnetic induction which implies that a conductor placed in a varying magnetic field will have an electromotive force, or e.m.f., induced in it proportional to the rate of change of the field. If a permanent magnet is suspended at or near the poles of a coil with an iron core, the coil will experience the required variable magnetic flux if the magnet is moved. A cantilever transfers the mechanical vibrations picked up from the record groove by the stylus directly into the permanent magnet. The changing magnetic field it produces induces a magnetic “flow” through the pole shoes which, in turn, generates an e.m.f in the fixed coils in direct proportion to the mechanical vibration. In this way, the sound wave captured as undulations in the record grooves has been converted into a tiny electrical signal which can then be amplified and converted back into sound by the speakers. 

The coil must be connected to a special phono amplifier input via the turntable leads so that the low voltage generated by the cartridge (typically 5 mV) is boosted to several volts to drive the speakers. All MM cartridges have a relatively high output and require a 47 kΩ load impedance for current to flow making them compatible with the basic phono input found as standard on many integrated amplifiers. If your amplifier does not feature a MM phono input, these can be purchased separately at a reasonable cost.
