A Custom Conversion for CD Players into CD Transports
The Transcend Conversion began as a service to existing owners of the DAX series of converters who were frustrated by the lack of availability of matching quality CD Transports. Now we are able to offer this customised service to the majority of CD Players or CD Transports, regardless of whether the model is current or no longer in production. The only provision is that there is sufficient space internally for the Transcend Electronics and Power Supply to be accommodated.
Elimination of CD’s Manufactured Imperfections
All CDs come with timing errors buried deep within their digital data. The elimination of these timing inaccuracies is essential for the faithful reproduction of an original performance. If these timing errors and any generated by the CD replay system are allowed to reach the precise point of conversion within the dac, they will create additional signals in the analogue domain – signals which were not present in the original recording. The Transcend Conversion replaces these imperfect timing waveforms read off the CD with immaculately formed originals.
The Master Oscillator – Transcend’s Heartbeat
The Transcend Conversion is driven by an ultra-stable, fully enclosed, vibration resistant master oscillator, which is entirely powered from its own multiple-regulated supply. The digital output is re-timed to this oscillator using extremely fast timing circuits separately powered through a total of 16 regulated supplies. A calculated degree of pre-compensation is applied prior to the output interfaces to correct the anticipated pulse spreading expected within the transmission medium.
Digital Output Connections
Two digital outputs are supplied as standard. The most popular quality connection is by 75ohm coaxial on a BNC or RCA socket. The alternative is the wideband glass optical ST/AT&T, which provides total electrical isolation and eliminates the impedance matching requirement of all the electrical interfaces. For convenience and completion a regular coded Toslink output is included, permanently coded in SPDIF.
Proprietary ‘N-Code’ Interface
In addition to the usual AES/EBU/SPDIF coded output, TRANSCEND Conversion includes two alternative and proprietary codings for improved sound quality.
The first of these is C-Code, which reduces frame related jitter and is compatible with all DAXes and the majority of commercial digital to analogue converters. More radical solutions to the problem of maintaining isolation, and thus low jitter between clock and data along the interface, are addressed with N-Code. N-Code additionally offers almost total elimination of audio band data related jitter but does require a custom decoding module within the dac – all DAX Decades include this module. Both C-Code and N-Code completely preserve all original data to ensure full compatibility with HDCD and 24 bit data paths.
