TEAC VRDS-701T CD-Transport m/VRDS

The VRDS-701T CD transport utilizes our newly-developed VRDS mechanism. The VRDS is a TEAC-original CD drive mechanism that reduces rotation vibration and other unwanted vibration by clamping the CD to an aluminum turntable with the same diameter in order to maximize inertial mass. When used in combination with a UD-701N playback is possible using the discrete DAC in the UD-701N as well as with MQA full decoding. Of course, you can also use it together with a DAC of your choosing, and build a system as you like. The inclusion of a 10MHz clock input enables flexible integration with systems that are synchronized using an external clock.

Newly-developed VRDS mechanism

Starting with a drive we developed that has a long record of use in broadcast applications, we added VRDS technologies, which are part of our TEAC legacy.

Vibration-Free Rigid Disc-Clamping System (VRDS)

This TEAC-original CD drive mechanism reduces rotation vibration of the disc itself as well as unwanted mechanism vibration by clamping the CD to an aluminum turntable with the same diameter and maximizing inertial mass in order to stabilize rotation. Servo current is reduced with the turntable by correcting disc warping and distortion and improving the relative optical axis precision of the pickup and disc pit side. This realizes reduced disc reading errors and outstanding audio quality.

Bridge section supports the VRDS

For the bridge that supports the turntable, we carefully selected lightweight materials that are very rigid and do not transmit vibration. By naturally settling vibrations quickly, we have realized a wide, dynamic sound. The bridge, which has a torus structure made of resin, is only fixed on one side, and propagation of vibration from the CD mechanism to the opposite side through the bridge is suppressed, so the entire mechanism minimizes unwanted sympathetic vibrations.

Semi-floating mounting

The entire CD mechanism is mounted on the sub-chassis in a semi-floating state. By controlling the transmission of vibrations between the CD mechanism and the chassis, the impact of sympathetic vibrations is abated, and natural playback sound is realized throughout the frequency range. By isolating motor vibrations from the main chassis, sympathetic vibrations within the chassis are prevented. At the same time, the CD mechanism is also isolated from external vibrations. Reading precision is also increased by isolating the CD mechanism from external vibrations.
