Azur 740C Upsampling CD Player

Azur 740C specifications

Features

Adaptive Time Filtering (ATF) Asynchronous upsampling

technology converting 16-bit 44.1 kHz CD data to 24-bit 384kHz

32-bit Analog Devices “Black Fin’ DSP

Dual differential DAC’s Wolfson WM8740 24 Bit DACs

running at 384kHz

Four Pole Dual Differential double virtual earth
balanced topology, maintains channel separation and

eliminates distortion

Digital inputs 2 co-axial, 2 optical allowing upsampling and

playback of other sources

Digital outputs 1 co-axial, 1 optical allows recording 

of raw or up-sampled audio (192kHz maximum)

Audio outputs 1 unbalanced

Other connections Control bus input/output, 1 IR emitter in,

1 IEC type mains inlet

Extruded aluminium side panels and solid aluminium
front panel

Low resonance, ultra rigid, acoustically dampened
chassis improves sonic performance

Full function aluminium face azur navigator remote

Available in silver/black
