KLAUDiO’s Magnezar Turntable.

Tracking Angle Exclusive: First Look at KLAUDiO’s Magnezar Turntable.

MICHAEL TROCHALAKIS SPENT A MONTH WITH THE FIRST PRODUCTION MODEL OF KLAUDIO’S NEW TURNTABLE, THE MAGNEZAR.

Peter Cheon founded KLAUDiO approximately 15 years ago, starting as a DIY hobby. In addition to the now famous KLAUDiO Ultrasonic Record Cleaning Machine KD-CLN-LP200T (having sold into the thousands) and pivoted tangential tonearm (KD-ARM-AP12), Cheon has also designed and built vacuum tube amplifiers (using esoteric broadcast transmitter tubes), vacuum tube preamplifiers, vacuum tube phono preamplifiers, moving coil step up transformers, tone arm headshells, digital display level meters, silver audio interconnect cables, and aluminum take up reels.  During the first five years of KLAUDiO, Cheon built tube amplifiers. He followed up with tube preamplifiers, the ultrasonic record cleaning machine, the pivoted tangential tonearm, and finally, a direct drive, magnetically levitated, auto clamping turntable.

 

피터 천은 약 15년 전 DIY 취미로 시작하여 KLAUDiO를 설립했습니다. 지금은 수천 대가 판매된 유명한 KLAUDiO 초음파 레코드 클리닝 머신 KD-CLN-LP200T와 피벗 접선 톤암(KD-ARM-AP12) 외에도 진공관 앰프(난해한 방송 송신관 사용), 진공관 프리앰프, 진공관 포노 프리앰프, 무빙 코일 스텝업 트랜스, 톤암 헤드쉘, 디지털 디스플레이 레벨 미터, 실버 오디오 상호 연결 케이블 및 알루미늄 테이크업 릴도 설계하고 제작해 왔습니다.  천 대표는 클라우디오의 첫 5년 동안 튜브 앰프를 제작했습니다. 이어서 그는 튜브 프리앰프, 초음파 레코드 클리닝 머신, 피벗 탄젠셜 톤암, 그리고 마지막으로 다이렉트 드라이브, 자기부상식 자동 클램핑 턴테이블을 개발했습니다.

 

The prototype of the Magnezar turntable was showcased in July 2023 at the Pacific Audio Fest in Seattle, Washington. Peter began developing this turntable approximately four years ago. When asked what inspired him to design a turntable, he mentioned the challenge in designing a quiet direct drive motor.

 

마그네자르 턴테이블의 프로토타입은 2023년 7월 워싱턴 주 시애틀에서 열린 퍼시픽 오디오 페스트에서 공개되었습니다. Peter는 약 4년 전부터 이 턴테이블을 개발하기 시작했습니다. 턴테이블을 디자인하게 된 계기를 묻는 질문에 그는 조용한 다이렉트 드라이브 모터를 설계하는 데 어려움이 있었다고 말했습니다.

 

 

Cheon states that the direct drive motor sourced for the Magnezar is primarily used in robotics. The motor has forty-five poles, and can produce ½ horsepower at 1,800rpm, but runs much lower for driving the turntable’s platter. The motor design was created in house by Cheon himself, who has an electrical engineering background. Prior to starting Koolance, KLAUDiO’s parent company which specializes in water cooling solutions for industrial applications (such as computers, medical equipment, theater projectors), Cheon spent approximately ten years designing motor control mechanisms for factories.

 

천은 마그네자르에 공급된 다이렉트 드라이브 모터는 주로 로봇 공학에 사용되는 모터라고 말합니다. 이 모터는 45개의 극을 가지고 있으며 1,800rpm에서 ½마력을 낼 수 있지만 턴테이블의 플래터를 구동할 때는 훨씬 낮게 작동합니다. 모터 설계는 전기 공학 배경을 가진 천 대표가 직접 만들었습니다. 컴퓨터, 의료 장비, 극장용 프로젝터 등 산업용 수냉 솔루션을 전문으로 하는 클라우디오의 모회사인 쿨런스(Koolance)를 창업하기 전에는 약 10년간 공장용 모터 제어 메커니즘을 설계한 바 있습니다.

 

 

The Magnezar’s platter, which weighs 44 lbs., is permanently magnetically levitated, even when the turntable is not in operation. The levitation is implemented using opposing neodymium magnets. There is a 3-5 mm clearance between the base of the turntable and the levitated platter.

 

무게가 44파운드에 달하는 마그네자르의 플래터는 턴테이블이 작동하지 않을 때에도 영구적으로 자기 공중에 떠 있습니다.부양은 반대편 네오디뮴 자석을 사용하여 구현됩니다.턴테이블 베이스와 공중부양된 플래터 사이에는 3~5mm의 간격이 있습니다.

 

 

The sub platter, which is encased with blue water, weighs approximately 3 lbs., and sits inside the main platter. Cheon states that when the turntable is in operation, the water in the sub platter creates a centrifugal force around the circumference of the platter that helps reduce wow and flutter. Cheon observed a measured improvement of 0.01% in wow and flutter when water was added to the sub platter.

 

파란색 물로 둘러싸인 서브 플래터는 무게가 약 3파운드이며 메인 플래터 안에 들어 있습니다.천 씨는 턴테이블이 작동 중일 때 서브 플래터의 물이 플래터 둘레에 원심력을 만들어 와우와 플러터를 줄이는 데 도움이 된다고 말합니다.천은 서브 플래터에 물을 추가했을 때 와우와 플러터가 0.01% 개선된 것을 측정했습니다.

 

 

The turntable’s automated clamping system consists of two parts: a spindle and a periphery clamp. The spindle clamp is spring controlled. Inside the platter are two motorized actuators which control the automated outer periphery clamping system. The two clamp pressures measure approximately 3 and 10lbs, respectively. When the clamping system activates, the lower platter circumference displays a warm white glow. Cheon has a patent pending for this clamping system.

 

턴테이블의 자동 클램핑 시스템은 스핀들과 주변부 클램프의 두 부분으로 구성됩니다.스핀들 클램프는 스프링으로 제어됩니다.플래터 내부에는 자동화된 외부 주변부 클램핑 시스템을 제어하는 두 개의 전동 액추에이터가 있습니다. 두 개의 클램프 압력은 각각 약 3파운드와 10파운드로 측정됩니다. 클램핑 시스템이 활성화되면 플래터 하부 둘레에 따뜻한 흰색 불빛이 표시됩니다. 천 대표는 이 클램핑 시스템에 대한 특허를 출원 중입니다.

 

 

The turntable can accommodate two tonearms, with both mounting bases featuring connections to allow activation of the automated clamping system when the tonearm is engaged towards the platter.

 

턴테이블에는 두 개의 톤암을 장착할 수 있으며, 두 마운팅 베이스에는 톤암이 플래터 쪽으로 결합될 때 자동 클램핑 시스템을 활성화할 수 있는 연결부가 있습니다.

 

The Magnezar operates at three speeds:  33 1/3, 45, and 78.26 rpm. The platter ramps up to speed and locks in within approximately 4 seconds. Stopping of the platter is accomplished through electronic braking.

Traditional platters rely on a mechanical thrust bearing and thrust pad. Thanks to the turntable’s magnetic levitation, this is not necessary, and mechanical transmission of motor noise to the platter is eliminated, making for an incredibly quiet listening experience.

 

마그네자르는 세 가지 속도로 작동합니다:  33 1/3, 45, 78.26 rpm입니다. 플래터는 약 4초 이내에 속도가 올라가고 고정됩니다. 플래터의 정지는 전자식 브레이크를 통해 이루어집니다. 기존 플래터는 기계식 스러스트 베어링과 스러스트 패드에 의존합니다. 턴테이블의 자기 부상 방식 덕분에 이러한 장치가 필요하지 않으며, 모터 소음이 플래터로 기계적으로 전달되지 않아 놀랍도록 조용한 청취 환경을 조성할 수 있습니다.

 

 

The Magnezar was evaluated with Cheon’s pivoted tangential tonearm (KD-ARM-AP12), which has been available for approximately five years. Cartridge swapping is very quick and easy with this tonearm since it uses an SME connection for the head shell. Overhang is adjusted with a sliding ‘sled’ at the base of the tone arm. A green laser projects a straight line perpendicular to the stylus for adjusting overhang. The tonearm has previously been reviewed, so the focus of this report is on the turntable.

 

마그네자르는 약 5년 동안 사용되어 온 천의 피벗 탄젠셜 톤암(KD-ARM-AP12)으로 평가되었습니다. 이 톤암은 헤드셸에 SME 연결을 사용하기 때문에 카트리지 교체가 매우 빠르고 간편합니다.오버행은 톤암 바닥에 있는 슬라이딩 '슬레드'로 조절할 수 있습니다.녹색 레이저가 스타일러스에 수직으로 직선을 투사하여 오버행을 조정합니다. 톤암은 이전에 검토되었으므로 이 보고서에서는 턴테이블에 초점을 맞춥니다.

 

 

On February 3rd, Cheon showcased the first production turntable at a listening event for the Pacific Northwest Audio Society. Approximately forty members of the society were in attendance. Due to the turntable’s ability to play 78 rpm records, those were also played at the listening event along with LP’s.

 

2월 3일, 천은 태평양 북서부 오디오 협회의 청취 행사에서 첫 번째 제작 턴테이블을 선보였습니다. 약 40명의 학회 회원들이 참석했습니다.이 턴테이블은 78rpm 레코드를 재생할 수 있기 때문에 청취 행사에서 LP와 함께 재생되었습니다.

 

 

The Magnezar is available through direct sales from KLAUDiO at a cost of $60,000. For anyone interested in listening to the turntable in person, Mr. Cheon invites prospective buyers to his Koolance/KLAUDiO offices near Seattle. A more comprehensive and in depth review of the Magnezar will be conducted in the near future by Michael Fremer.

 

마그네자르는 클라우디오의 직접 판매를 통해 6만 달러에 구입할 수 있습니다. 이 턴테이블을 직접 들어보고 싶은 분들을 위해 천 대표는 시애틀 근처에 있는 쿨런스/클라우디오 사무실로 잠재 구매자들을 초대하고 있습니다.마그네자르에 대한 보다 포괄적이고 심층적인 리뷰는 조만간 마이클 프레머가 진행할 예정입니다.
