TEAC TN-4D Analog Turntable

Analog TurntableTN-4DEmploying a new ultra-stable, direct-drive motor,a classically designed turntable with knife-edge tonearm bearings採用新型超穩定直驅馬達，帶有刀緣音臂軸承的經典設計唱盤The TN-4D is a direct-drive, analog turntable with an elegant, low-profile design, made possible by the use of a newly-developed brushless DC servo motor.Our new brushless DC motor (with feedback control system) achieves crystal-locked speed stability and smoother rotation while also eliminating cogging*. This low-profile motor allowed us to design a plinth that’s extraordinarily sleek and stylish compared to that of most other direct drive turntables. The new tonearm employs knife-edge, pivot-point bearings, developed in collaboration with SAEC Corporation, a world-famous, high-end tonearm manufacturer. The result is an insightful, high-resolution sound quality that tonearms with conventional bearings can’t match. Partnering it is a carefully designed PHONO EQ amplifier that allows you to directly connect the turntable to the line-level inputs of your existing hi-fi system. A high quality NJM8080 op-amp, specially designed for hi-fi applications by New Japan Radio Corporation, is employed to convey the finest of musical detail. Additionally, a USB port on the back panel allows you to digitally archive your vinyl collection via your PC/Mac.To extract the music from your vinyl, the TN-4D comes with a highly-regarded Oyster MM cartridge from SUMIKO – a legendary American cartridge manufacturer. Noted for its innate musicality, the cartridge comes pre-installed on the headshell at the factory, allowing near ‘plug and play’ operation. The S-shaped tonearm meanwhile allows for quick cartridge/headshell swaps, so users can alter the sound quality by experimenting with different cartridges, if the desire takes them.The TN-4D is an analog turntable that achieves highly accurate rotational speeds and is very distinctive, for a direct-drive design, thanks to its sleek and stylish aesthetics.What is Cogging?Cogging is a phenomenon in which the periodic attraction of the armature and rotor inside the motor is dependent on the rotation angle, resulting in a fine pulsing. For example, if you turn the axle of a motor with your fingers, you'll feel the rotation occurring in steps. This phenomenon is known as cogging.In order to eliminate cogging on a direct-drive turntable, a motor needs to have large numbers of poles, along with complex circuits and a mechanism to achieve smooth rotation. As a result, most turntable direct-drive units are relatively large, which is why the resulting turntables are so bulky.TN-4D是一款直接驅動的模擬唱盤，採用新開發的無刷直流伺服馬達，具有優雅的輕薄型設計。我們的新型無刷直流馬達（帶反饋控制系統）在消除齒槽的同時，實現了晶體鎖定的速度穩定性和更平穩的旋轉。與其他大多數直接驅動唱盤相比，這種低姿態的馬達使我們能夠設計出一個非常光滑和時尚的底座。新款唱臂採用刀緣式樞軸點軸承，與世界著名的高端唱臂製造商SAEC公司合作開發。成果是一種富有洞察力的高分辨率音質，與傳統的軸承手臂無法匹配。它是一個精心設計的PHONO EQ擴大器，允許您直接連接唱機到現有高保真係統的線路電平輸入端。高音質的NJM8080運算擴大器是專為新日本無線電公司的高保真應用而設計，用於傳達最精美的音樂細節。此外，後面板上的USB端口允許您通過PC / Mac以數碼方式存檔您的黑膠唱片集。為了從您的黑膠唱片中提取音樂，TN-4D配備了SUMIKO備受推崇的Oyster MM唱頭 ， 一個傳奇的美國唱頭
