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.
