Teac Reference 500 Series CD Transport in Black - PD505TB

This long-awaited CD transport in the Reference 500 Series employs a CD drive with a new design based on specifications we have used for professional products.

Based on our original CD drive design used in the CD-5020A, which boasts a record for many years of use by professional products, we developed a new design optimized for the PD-505T.

Utilizing semi-floating mounting and a new drive circuit design, we have realized CD reading that is accurate and maintains a high level of purity.

 

With support for 10MHz clock input, not only can this transport be used together with a TEAC Reference 500 Series DAC, it can also be used flexibly to enable high-quality audio CD playback with a variety of digital playback systems.

Dedicated CD drive design improves on the drive developed for the TEAC CD-5020A

The CD-5020A is a TEAC original drive that we are proud to have developed. This his has been used for professional applications because of its durability and reliability. Based on the CD drive design used in the CD-5020A, we developed a new design optimized for the PD-505T.

The entire CD mechanism is mounted in a semi-floating state that is not completely fixed to the chassis of the unit. This design, developed with meticulous care, prevents feedback that can have a negative impact on CD reading by preventing the transmission of vibrations generated by the spindle motor and actuator to the chassis and causing sympathetic vibrations. At the same time, in order to eliminate impact on the audio quality from dampers used when mounting drive components, we also designed locations where we employed rigid attachment methods, for example, and considered overall vibration modes in making a structure that employs both rigid and flexible aspects. By doing so, we have realized CD reading that is more accurate and maintains a higher level of purity.

Drive control circuit with a new design

Seeking an even higher level, we designed a new drive control circuit for the CD mechanism. By controlling the spindle motor with gentle feedback to create a natural rotating state, we have realized an even more unaffected and open sound. Furthermore, BTL drive, which does not generate switching noise, is utilized, starting with the spindle and also including the actuator that drives the pickup lens. This eliminates minute impacts on signal reading and increases the purity of the signal.

10MHz external clock input

The sound can be enhanced further by inputting an even higher precision clock signal from an external source. Moreover, in a digital playback system, not only can audio quality be enhanced by increased upstream precision, building an even higher level digital system becomes possible through, for example, clock synchronization with a DAC.

All-metal enclosure provides both vibration resistance and a stylish appearance in an A4 footprint that can fit on a desk

Since the entire body is constructed from metal panels that are resistant to external noise, intrusion of electromagnetic noise generated by computers and other devices is suppressed. This achieves a clean internal environment with little noise even in conditions that are difficult for audio equipment. Furthermore, the 8mm-thick aluminum panels, which cover both sides of the all-metal chassis, provide an installation structure that does not unnecessarily twist or bend the chassis or front and back panels, realizing a strong and precise form. Moreover, with the size of an A4 page (viewed from above), the unit can be placed on a desk, side table or other small space.

Semi-floating top panel

A semi-floating top panel design is utilized. The top panel is not tightened to the chassis with screws. Instead, it is partially fixed, secured only by the side panels, realizing a sound instilled with an open feeling.
