PRODUCT OVERVIEW
The dCS Verdi SACD Transport has been developed to bring the benefits of the
Super Audio CD into the dCS fold.
Verdi plays SACD or Hybrid discs and outputs the DSD data onto an IEEE 1394
bus, ready for conversion to wide-band, high quality audio by a dCS Elgar Plus
or a 1394-equipped dCS Delius

.
DSD (Direct Stream Digital) is single bit data, sampled at 2.822MS/s. This data
format increases the available audio band-width to well over 100kHz, well in
excess of the 20kHz available from a standard CD system. The extra band-
width sharpens the transient response and improves the phase response,
resulting in a more natural sound and more precise stereo imaging.
Verdi also plays standard CDs, outputting 16 bit / 44.1kS/s data on the AES
interface (XLR connector), three SPDIF interfaces (RCA, BNC and Toslink
optical and an SDIF-2 interface. The CD data may be improved by upsampling
to DSD using a 1394-equipped dCS Upsampler.
Verdi features a Wordclock Input, allowing the transport to be synchronised to a
Master Clock or a dCS DAC running in master mode. This arrangement reduces
system jitter – a major source of sound degradation in digital audio systems.
In common with all dCS converters, Verdi is based on our flexible digital audio
platform which makes extensive use of software configurable chips – FPGA’s
and DSP’s. This allows the internal software to be updated from time to time,
either from a dCS CD or from a PC, adding extra features and facilities to your
system with a minimum of fuss.
