840C Upsampling compact disc player
Azur upsampling compact disc player 7
Control Bus
In - Allows un-modulated commands from multi-rooms systems or other
components to be received by the unit.
Out - Loop out for control bus commands to another unit.
Digital outputs
The digital outputs allow a separate DAC or digital recording device to be
connected. The sophisticated DSP software in the 840C even allows
these outputs to be set to output raw (pass through) or upsampled data
independently from the main audio outputs. Refer to the ‘Operating
instructions’ section for more information.
S/P DIF CO-axial Digital - To obtain best results, use a high quality 75
ohm digital RCA interconnect cable (not one designed for normal audio
use).
Toslink Optical Digital - Use a high quality TOSLINK fibre optic
interconnect cable designed specifically for audio use.
Only one of the two output types should be used at a time.
& Digital Inputs 1 / 2
The digital inputs allow the digital outputs of other source components
to be connected to the 840C. The 840C can then act as a very high
quality upsampling DAC, improving the sound quality of the connected
sources. Two digital inputs allow two external sources to be connected:
S/P DIF CO-axial Digital - Use a high quality 75 ohm digital RCA
interconnect cable (not one designed for normal audio use).
Toslink Optical Digital - Use a high quality TOSLINK fibre optic
interconnect cable designed specifically for audio use.
Only one of the two input types for each input should be used at a time.
Unbalanced Audio Out
Single-ended conventional stereo outputs for connection to the line-level
phono/RCA inputs of an amplifier.
Balanced Audio Out
The 840C also features true balanced (XLR) outputs. This is a higher
quality output that can reject noise and interference in the cable when
used with equipment with balanced inputs. XLR connectors should be
wired: Pin 1 - Ground; Pin 2 - Hot (in-phase); Pin 3 - Cold (phase-
inverted).
