Unbalanced Audio Output
A conventional RCA phono stereo output for connection to the line-level
inputs of an amplifier. Use a high quality stereo RCA phono interconnect
cable intended for analogue audio signals.

Balanced Audio Output
The 851D features balanced outputs on two XLR sockets. Balanced
outputs provide slightly better audio performance and can reject cable-
borne noise and interference when used with equipment with balanced
inputs.
Note:
XLR connectors should be wired as follows:
Pin 1:
Ground
Pin 2:
Hot (in-phase)
Pin 3:
Cold (phase-inverted)

Standby/On
Switches the unit between Standby mode (indicated by dim power LED)
and On (indicated by bright power LED). Standby is a low power mode
where the power consumption is less than 0.5 Watts. The unit can be left
in Standby mode when not in use.
2
Headphone connection
Allows for the connection of headphones with a ¼" jack plug connector.
Note:
600 Ohm headphones will work well on the 851D. However, with
some less sensitive models maximum volume maybe limited. If louder
listening is required, a lower impedance / higher sensitivity set of
headphones is recommended.

Menu
Press to enter the 851D's setup menus. Various 851D operating
parameters can be configured. Refer to the 'Operating instructions'
section for more information.
4
Filter
The different digital filters can be selected from the 851D’s setup
menu. Alternatively, pressing the Filter/
ø
button on the remote will cycle
through different digital filter phase modes: Linear, Minimum, Steep,
Linear inverted, Minimum inverted and Steep inverted. Alternative digital
filters can offer subtly different sound quality characteristics. See later
section for further details. The currently selected filter is displayed by the
indicators just above the button.
Phase
Press the Filter button on the remote to cycle through different phase
output.
If you suspect that your source material or amplifier, etc., is inverting the
phase of the musical signal, you can use this function to re-invert the
audio and regain absolute positive phase by pressing the phase button
in the setup menu. Alternatively, to select using the remote control, cycle
through the modes as described above.
5
Infrared sensor
Receives IR commands from the supplied Azur remote control. A clear
unobstructed line of sight between the remote control and the sensor
is required.

Volume
When Pre-amp mode is enabled, use to increase/decrease the level of
the sound from the outputs of the pre-amplifier. This control affects the
level of the analogue audio output, and the headphones output. It does
not affect the digital output connections
Please refer to the 'Operating instructions' section of this manual for
more information on some of the functions of these buttons.
