Equipped with a CD Transport Mechanism Enhanced from TEAC’s Proprietary CD-5020A
The CD-5020A is a CD transport mechanism designed and manufactured by TEAC, renowned for its robustness and reliability, and has been used in broadcast CD players for many years. Building on the legendary CD-5020A, the mechanism in the PD-507 has been further refined to deliver even higher sound quality.
Semi-Floating Drive Mount
The entire CD mechanism is mounted on the main chassis with a semi-floating construction that is not fully attached to the chassis. The mounting system has been carefully designed to prevent vibrations from the spindle motor and actuator from being transmitted to the chassis and adversely affecting CD reading. On the other hand, some drive components are rigidly mounted without the use of dampers, eliminating the sound coloration caused by soft elastic material. By employing a structure that utilizes both rigidity and flexibility, the PD-507 achieves more direct and precise CD reading.
Drive Control Circuitry, Precisely Tuned for High-Quality Playback
The drive control circuit of the CD mechanism is meticulously custom tuned for the PD-507T to achieve high-quality playback. A natural and open sound is achieved by using a slower feedback loop to control the spindle motor. The spindle and pickup lens drive actuator are driven by a BTL circuit, which does not generate switching noise, resulting in pure signal reading.
Discrete Power Supply Circuit with A Toroidal Transformer
The PD-507T uses a discrete power supply circuit with a toroidal core transformer with triple secondary windings and triple rectifier circuits. These independently power the audio circuit, the CD drive and microcomputer, and the display circuit.
This design minimizes noise within the audio signal and maximizes playback clarity.
The audio circuit power supply has been improved from that of the previous generation model. By using separate power supplies for the clock and digital output, the PD-507T has achieved an even higher level of sound quality.
Upgraded Mechanical Construction and Circuits Achieve Even Higher Sound Quality
Compared to the previous generation model, the mechanical construction has been finely tuned and adjusted for more effective vibration control. Electrically, the grounding of the entire circuit was further optimized, and the OLED display circuit's noise isolation was advanced for purer signal output.
The Selectable Coaxial/Optical Digital Output for Maximum Signal Purity
The PD-507T allows you to select between coaxial and optical digital outputs. Disabling the operation of unused digital output circuits reduces the overall circuit load, thereby enhancing the purity of the output signal.
Low Phase Noise Crystal Oscillator
In digital links, the clock accuracy of the upstream device is very important because it affects the quality of the entire system. The PD-507T employs a high-performance, low phase noise crystal oscillator for its internal clock. The high-precision reference clock enables the PD-507T to read the signal from the CD with extreme precision, reproducing the original sound recorded on the CD with true authenticity.
10MHz External Clock Input
The PD-507T can be connected to the CG-10M-X master clock generator to receive a higher-precision clock signal. If the DAC has an external clock input, you can synchronize the CD transport and the DAC by connecting the two clock outputs of the CG-10M-X to the transport and the DAC simultaneously to further enhance the sound quality of your system.
Luxurious, Anti-Resonance Metal Enclosure
The full-metal enclosure shields the system from electromagnetic noise, preserving the PD-507’s clean and pure sound. The cabinet is solidly constructed with heavy-duty 8mm aluminum side panels, which also feature a unique mounting structure that does not place unnecessary mechanical stress on other parts of the cabinet, resulting in a neutrally tuned cabinet.
The foam factor of elegant, space-efficient design that allows you to install the unit in the smallest of spaces on an audio rack, desk or sideboard.
TEAC's Proprietary 3-Point Support Stress-Less Isolation Foot
TEAC’s proprietary Stress-Less Isolation Foot is precision-machined from solid steel. By allowing slight movement at the joint between the bottom plate and the foot, it achieves precise imaging and a rich, natural sound. The 3-point support system also ensures a stable installation, unaffected by even the slightest distortion in the floor surface.
Semi-Floating Top Panel
To enhance sound openness and natural sound signature, the PD-507T’s aluminum top panel is semi-floating, sitting in place without screws, secured via precision slots in the side panels.
System Control Function
The PD-507T is equipped with trigger input/output terminals. It can be used to turn the power on and off in conjunction with the power operation of other devices equipped with trigger output terminals.
