NAGRA REFERENCE MC CARTRIDGE

NAGRA REFERENCE MC CARTRIDGE

The Nagra Reference MC cartridge is the product of a number of years of intense R&D supplemented by extensive listening tests. This moving coil cartridge is available in 4 and 6 Ohm variants. Designed in parallel with the Nagra 70th Anniversary Reference turntable/tonearm system, it is an ideal companion component to complete the ultimate LP playback platform.

First 100 units will be delivered in a special luxury aluminum box.

The Reference MC cartridge features a number of significant and unique elements. While traditional moving coil transducers utilize a single layer coil body, the Nagra Reference MC cartridge employs a multi-layer transducer featuring a double layer coil body wound with hyper-pure silver windings. The 6 Ohm Reference outputs 0.45mV @ 5cm/S. The 4 Ohm Reference achieves an output of 0.30mV @ 5 cm/S.

 

Nagra 레퍼런스 MC 카트리지는 다년간의 집중적인 연구 개발과 광범위한 청취 테스트를 통해 완성된 제품입니다. 이 무빙 코일 카트리지는 4옴 및 6옴 버전으로 제공됩니다. Nagra 70주년 기념 레퍼런스 턴테이블/톤암 시스템과 병행하여 설계된 이 제품은 궁극의 LP 재생 플랫폼을 완성하는 이상적인 컴포넌트입니다.

 

선착순 100대는 특별한 고급 알루미늄 박스에 담겨 배송됩니다.

 

레퍼런스 MC 카트리지는 여러 가지 중요하고 독특한 요소를 갖추고 있습니다. 기존의 무빙 코일 트랜스듀서가 단일 레이어 코일 바디를 사용하는 반면, Nagra 레퍼런스 MC 카트리지는 고순도 실버 권선으로 감긴 더블 레이어 코일 바디를 특징으로 하는 멀티 레이어 트랜스듀서를 채택했습니다. 6옴 레퍼런스는 5cm/S에서 0.45mV를 출력합니다. 4옴 레퍼런스는 5cm/S에서 0.30mV의 출력을 달성합니다.

 

 

CANTILEVER

A stiff ruby cantilever is mated to a high strength titanium structure featuring a DLC (diamond-like carbon) coating. The titanium structure utilized in the coil body/cantilever interface addresses a traditional source of resonance and substantially reduces vibration unrelated to the musical signal. The stylus tip is a Swiss produced, Fritz Gyger S profile chosen for its wonderful combination of detail retrieval and musicality.

 

단단한 루비 캔틸레버가 DLC(다이아몬드형 탄소) 코팅이 적용된 고강도 티타늄 구조에 결합되어 있습니다. 코일 바디/캔틸레버 인터페이스에 사용된 티타늄 구조는 기존의 공진 소스를 해결하고 음악 신호와 무관한 진동을 크게 줄여줍니다. 스타일러스 팁은 스위스에서 생산된 프리츠 가이거 S 프로파일로, 디테일 재현과 음악성의 훌륭한 조합을 위해 선택되었습니다.

 

CONNECTORS

Further evidence of the obsessive attention to detail in the cartridge’s design is found in the connector pins. Those employed in the Reference MC cartridge eliminate the commonly found connection joint between the pin and the coil. In the case of the Reference MC, the pin is a continuous single piece from its external end point to its internal point of contact with the coil, resulting in a welcomed lowering of inductance.

 

카트리지 설계에서 디테일에 대한 집요한 관심의 또 다른 증거는 커넥터 핀에서 찾을 수 있습니다.레퍼런스 MC 카트리지에는 일반적으로 볼 수 있는 핀과 코일 사이의 연결 조인트가 없습니다.레퍼런스 MC의 경우, 핀은 외부 끝점부터 코일과의 내부 접촉 지점까지 연속적인 단일 부품으로 되어 있어 인덕턴스를 낮출 수 있습니다.

 

BODY

In addition to the extensive focus on the generator system and groove/stylus/ cantilever interface, Nagra’s team of engineers and designers paid great attention to the Reference MC cartridge body. Substantial material science investigation lead the team to a unique, non-ferrous alloy called EXIUM® AM. Born from aerospace materials research, EXIUM® AM is the result of a collaboration between the CNES (the French equivalent of NASA), the Ecole de Mines de Paris and the French firm LBI Foundries. It was developed to address the need for an alloy with very high damping properties – a necessary attribute for a particular Mars mission whose purpose was to measure minute seismic activities on the red planet.

 

Nagra의 엔지니어와 디자이너 팀은 제너레이터 시스템과 그루브/스타일러스/캔틸레버 인터페이스에 집중하는 것 외에도 레퍼런스 MC 카트리지 본체에도 많은 관심을 기울였습니다.상당한 재료 과학적 조사를 통해 팀은 EXIUM® AM이라는 독특한 비철 합금을 찾아냈습니다.항공우주 재료 연구를 통해 탄생한 EXIUM® AM은 프랑스 국립과학원(CNES), 파리 공과대학(Ecole de Mines de Paris), 프랑스 기업 LBI 파운드리가 협력한 결과물입니다. 이 소재는 화성에서 미세한 지진 활동을 측정하는 것이 목적인 특정 화성 탐사에 필요한 특성인 매우 높은 감쇠 특성을 가진 합금의 필요성을 해결하기 위해 개발되었습니다.

 

 

Nagra engineers determined that this high damping characteristic alloy was perfect for use in audio applications where the elimination of unwanted vibrations and resonances is an extreme priority. As a result, the Reference cartridge utilizes an EXIUM® AM inlay at the critical interface between cartridge generator and the cartridge body. (An examination of Nagra’s 70th Anniversary Reference turntable will reveal that the table’s platter features a precisely CNC machined ring of EXIUM® AM.) Nagra’s use of EXIUM® AM is exclusive. Nagra has secured the sole worldwide right to use EXIUM® AM in audio products. In order to produce a cartridge of optimal weight for the Reference Anniversary tonearm, while maintaining high internal damping properties, a proprietary super magnesium alloy is utilized for the balance of the cartridge body.

The Nagra Reference cartridge has exceptional tracking ability, resonance control and exemplary specifications. It will match most tonearms and phono stages but will reach its ultimate potential when paired with the Nagra Reference turntable/tonearm system and Nagra phono stages.

 

Nagra 엔지니어들은 이 고감쇠 특성 합금이 원치 않는 진동과 공진 제거가 최우선 과제인 오디오 애플리케이션에 사용하기에 적합하다고 판단했습니다.그 결과 레퍼런스 카트리지는 카트리지 제너레이터와 카트리지 본체 사이의 중요한 인터페이스에 EXIUM® AM 인레이를 사용했습니다.(Nagra의 70주년 기념 레퍼런스 턴테이블을 살펴보면 테이블의 플래터에 정밀하게 CNC 가공된 EXIUM® AM 링이 장착되어 있음을 알 수 있습니다).Nagra의 EXIUM® AM 사용은 독점적입니다. Nagra는 오디오 제품에 EXIUM® AM을 사용할 수 있는 전 세계 유일의 권리를 확보했습니다. 레퍼런스 애니버서리 톤암에 최적화된 무게의 카트리지를 생산하면서도 높은 내부 댐핑 특성을 유지하기 위해 카트리지 바디의 균형을 위해 독점적인 슈퍼 마그네슘 합금을 사용했습니다.

 

Nagra 레퍼런스 카트리지는 탁월한 트래킹 능력, 공진 제어 및 모범적인 사양을 갖추고 있습니다. 대부분의 톤암 및 포노 스테이지와 잘 어울리지만 Nagra 레퍼런스 턴테이블/톤암 시스템 및 Nagra 포노 스테이지와 함께 사용할 때 최고의 잠재력을 발휘합니다.
