Combines a Word-Sync Function with the World's Most Unique VRDS Mechanism, and a D/D (Digital-to-Digital) Converter that Can Perform Sample Rate
VRDS mechanism (employing a aluminum tapered turntable and turntable bridge)
The VDRS assembly, though secure clamping to a turntable of the same diameter as the disc being played, totally removes unnecessary vibration; either from mechanical sources, or from the typical vibration of a disc. Rigidity is also achieved through the use of a turntable bridge composed of precision processed carbon tool steel. The shape of the turntable also helps to correct any warp in the disc. Because of the precise alignment of the optical axis produced by this arrangement, the servo current is reduced. All of the above factors decrease the disc read error rate, and help to prevent timing errors from the clock circuit.
The P-70 can achieve word synchronization by accepting a master clock from any suitably-equipped D/A converter. With the converter acting as the master clock, any jitter resulting from data transfer between the player and the converter is essentially eliminated.
Twin-transformer structure, with the power supply completely separated from the mechanical and digital signal systems
To eliminate mutual interference, the important key components of the player: power supply, mechanism control, and digital system (word sync, frequency multiplier, and clock) have been separated completely in the design. There are two split-core transformers in the power supply for additional interference rejection.
7 digital outputs, including 4 digital outputs from the converter multiplier (2xFs, 4xFs)
The player has four (XLR x 2, RCA x 1, TOS x 1) digital output terminals to handle the high-speed multiplied digital outputs (2xFs:24 bits at 88.2kHz, 4xFs: 24 bits at 176.4kHz), in addition to 3 "standard" digital output terminals (RCA x 1, TOS x 2) 44.1kHz. Following the dual AES specification, 4xFs (24bits at 176.4kHz) audio is output from twin XLR terminals The operational algorithm employed in the converter multiplier circuit is the RDOT method; exclusive to TEAC Corporation.
High rigidity chassis and triangular pinpoint feet
Based on 8 mm thick sheet steel, with the VRDS mechanism attached directly, and employing H-type 20 mm thick extruded aluminum. The front panel and the sides employ a construction method in which the 1.6 mm thick sheets are first plated with copper, and then with nickel. This two-layer design succeeds in totally removing internal interference, and helps to optimize the sonic performance. With the triangular pinpoint feet composed of case-hardened tool steel, vibration is almost completely eliminated.
