The digital output provided by the 500 Compact Disc Transport

can be decoded by the 566 20-Bit Digital to Analogue Converter

to provide a high-quality audio output for use with a

conventional audio preamplifier. The 566 20-Bit Digital to

Analogue Converter can also decode digital signals from other

sources, including LaserDisc players and Digital Audio Tape.

The 502 Analogue Controller is a full function preamplifier for use

with any analogue source, and includes balanced inputs to allow

you to take advantage of balanced sources, including the 566

20-Bit Digital to Analogue Converter. It provides balanced

outputs which are ideal for use with the 557 Stereo Power

Amplifier.
