HDCD

compatible with automatic switching

24 bit data processing

Single bit digital to analogue converter with 20 bit resolution and
192 times oversampling

Ultra linear, low-noise, low-distortion single-bit conversion

‘Straight Line Technology’ links the digital to analogue
converter to the audio output

Very low noise master clock synchronises with the digital data
input to minimise jitter

Automatic sampling frequency selection

Automatic de-emphasis

Microprocessor control

Automatic and manual muting

Immunity to electromagnetic interference enhanced by double
layer, epoxy glass printed circuit board technology

Linear phase output filters with high-quality, high-stability active
and passive components

Three coaxial SPDIF inputs with phono and BNC sockets

AES/EBU balanced input with XLR socket

Three optical EIAJ inputs

Two low-impedance analogue stereo outputs to allow long
cable runs

Coaxial SPDIF digital output with precisely retimed signal for
high-quality digital recording
