Using this handbook
This handbook has been designed to give you all the
information you need to install, connect, set up and use the
Arcam CD93 compact disc player. The CR-314 remote control
handset supplied with this equipment is also described.
Safety
Safety guidelines are set out on the inside front cover of this
handbook.
Many of these items are common sense precautions, but for
your own safety, and to ensure that you do not damage the
unit, we strongly recommend that you read them.
Digital to Analogue conversion
The CD93 incorporates the latest audio up-sampling technology
to convert the 44.1kHz data from the CD up to 192kHz in
24-bit precision using the Analog Devices AD1896 sample rate
converter.
The 192kHz audio data is converted into the analogue domain
using four Wolfson Micro WM8740 24-bit stereo DACs. Left and
right output channels are made using two stereo DAC chips
per channel, both operating in dual mono configuration. The
resulting four mono signals (two for each channel) are summed
together to help improve dynamic range, linearity and therefore
distortion.
Due to the higher sample rates, the digital filters roll off less
aggressively than for standard DACs, and the analogue filters
have a wider bandwidth resulting in less phase distortion,
particularly for the higher frequencies.
