Cartridges & Styluses Grey 6 Items

Replacement stylus for Shure M44G.

This product is a NAGAOKA produced and manufactured replacement stylus for the M44G, a cartridge widely used by DJs around the world. We have received many inquiries about a replacement stylus compatible with the M44G, since we had 'GD63-44G' in our lineup. After the production of 'GD63-44G' was discontinued, we reviewed the specifications and developed a new model. The new DJ-44G has a high sound pressure, delicate, wide-range, and powerful sound while keeping main features of toughness and solidity from the original M44G replacement.

The 2M 78 features an improved engine, which provides a high level of sonic accuracy. The stylus' tip is a Spherical diamond that is perfect for playback of 78 rpm shellac records, which require a larger stylus profile. The cartridge body is manufactured from Hopelex, which ensures high rigidity while eliminating unwanted resonances.

2M 78 uses a strapped output to deliver the same output signal from both sets of pole pins. This effectively eliminates the need for mono-specific equipment, making it possible to enjoy true mono reproduction on any stereo playback system.

The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.

2M 78 Technical data:
• Output voltage at 1000 Hz, 5cm/sec. - 4 mV
• Frequency response - 20-20.000 Hz + 3 / - 1 dB
• Tracking ability at 315Hz at recommended tracking force - 70 µm
• Compliance, dynamic, lateral - 18 µm/mN
• Stylus type - Spherical
• Stylus tip radius - R 65 µm
• Tracking force range - 1.6-2.0g (16-20 mN)
• Tracking force, recommended - 1.8 g (18 mN)
• Internal impedance, DC resistance - 700 Ohm
• Internal inductance - 350 mH
• Recommended load resistance - 47 kOhm
• Recommended load capacitance - 150-300 pF
• Tracking angle - 20°
• Cartridge colour, body/stylus - Black/Grey
• Cartridge weight without screws - 7.2 g
• Premounted cartridge weight - 16.7 g
• Replacement stylus unit - 2M 78 (interchangeable with 2M Mono)

Stylus lifetime: with proper care we find that up to 1000 hours is possible without degradation of performance.

2M Series styli interchangeability:
The 2M Series' engines, coils and magnets configurations are not identical: Red and Blue are identical, so are the Bronze and Black and so are the true mono variants 2M Mono and 2M 78. Likewise, 2M series styli are interchangeable within the below combinations:
- 2M Red, 2M Blue and 2M Silver
- 2M Bronze and 2M Black
- 2M Mono and 2M 78

Compatibility with Rega brand TT/TA:
REGA brand cartridges’ height from stylus tip to the top cartridge mounting surface is lower than standard. Therefore you would need spacers to ensure the correct set-up of the Ortofon cartridge.
Adjusting the height of your Rega tonearm is easy with Acoustic Signature's Spacer Set. It allows you to adjust the height from 0.5 mm to 3.5 mm in precise steps of 0.5 mm - without removing the tone arm. Simply loosen the screws, insert the AS-spacer, then lock the screws back down, and you're tonearm is ready to play.
3.2 - 4 mm spacers should be enough for 2M cartridge.

Electronic stylus balance

The Measure it E Stylus Tracking Force Gauge is a highly accurate electronic balance that is designed for measuring stylus tracking forces up to 5.0 grams in 0.002 gram increments. Each Measure it E can easily be calibrated using the supplied calibration weight and by pushing a button. Whenever in doubt about the actual amount of pressure on the diamond tip the 4 digit display of this smart tool will help. Armed with precise information about tracking force, your stylus tip wear can be significantly reduced.

General purpose model for scratch and back-cueing

Great performance and durability as to basic scratch and back-cueing is what the Pro is known for. It has a good quality spherical stylus, a rock-solid cantilever, and serves general purposes well.

The Pro is the logical alternative to the more expensive expert carts. It offers both reasonable output and high sound quality which is, in fact, all there is needed to entertain an audience.

The Pro Series of cartridges provides a great balance of sound quality with tracking ability, for virtually any style of music.
