The Ti48 CD Transport reads CDs and outputs the digital data to any outboard digital-to-analogue converter (DAC).

It also has a software-enabled upsampling processor built-in that allows users to choose the sampling frequency and the digital filter to be set. When connected to Zero One DACs using our custom I2S link , the sampling frequency could be set at various rate (e.g. 48k,176.4k) up to a maximum of 192khz. If the S/PDIF (coaxial) link is used, the Ti48 can transfer data up to a maximum sampling rate of 96khz due to the limitations of the S/PDIF standard. Even if you already own a high end upsampling 24/96 DAC, you will find that the upsampled data from the Ti48 will help to extract the highest level of performance from your DAC.

The digital filter algorithms allow you to tailor the sound to your system or room to some degree. There are three filter options ranging from "minimal" to "brick wall". In addition, there are various dither options which help to optimise the performance of some DACs when the S/PDIF connection is used.

Last but not least, the Ti48 has 240Gb of hard-disk capacity which enables it to save over 350 hours of uncompressed CD data. The Ti48 can store either an entire CD or selected tracks. These can be organised according to artist or album name and genre such as "jazz" or "rock" . Using these classifications, playlists can be created containing preferred tracks. The Ti48 has a database that recognises the album titles, track and artist names of over 500,000 CDs. This database can be easily upgraded with a CD-ROM (available from Zero One).
