Wired/Wireless connection
It is possible to connect your 851N to your network via an available Ethernet
connection (RJ45) or via a Wi-Fi router. By default the unit is in AUTO mode, each
time you turn the unit it looks for the presence of a wired connection, and tries to
use this, if none is present or it cannot connect it then tries to use the wireless
connection and so on. In Auto mode once the 851N has established a certain type
of connection to the network, then this type of connection will remain in use while
the 851N is on.
You can alternatively configure the 851N to permanently only use the wired or
wireless connection from the 851N’s 'Network' menu, select 'Wired/Wireless'. This
menu will present you with three options: 'Auto', 'Wired Only' and 'Wireless Only'.
Selecting 'Wired Only' will cause the 851N to reboot and then only use its Ethernet
connection to communicate with the network. Selecting the 'Wireless Only' will
cause the 851N to reboot and only use its Wi-Fi connection. Selecting the 'Auto'
option means the 851N will try both and settle on the one it can make work as
described above.
Firmware
This menu item displays some hardware/software version numbers for your 851N.
Turn the rotary dial to scroll through the various items.
The Service Pack is the currently loaded firmware software. It’s a good idea to
note this down if you need to contact our technical support people as they may
request it.
The Serial Number and Product Code are not normally required by the technical
support team.
Note:
This Serial Number is not the same as the physical serial number on the back
of the product itself.

Check for updates
Use this option to download new firmware for the 851N from Cambridge Audio over
the Internet.
If you select this item the 851N will contact our server and see if a newer version of
software is available (‘Checking for updates’ will be shown in the display).
If new software is found the 851N will prompt you and ask if you want to download it
or not. It is a good idea to update the firmware from time to time to take advantage
of any bug fixes or new features. At this stage, you can press the 851N’s
button
to cancel the firmware upgrade. A Firmware upgrade may take several minutes.
Note:
– It is very important that once the Firmware upgrade has started you do not switch
off the power to the 851N until the operation is complete otherwise the 851N
may become permanently damaged.
– Also do not interrupt the network or internet connection by removing the Ethernet
lead or switching off your router etc.

Display brightness
Alters the brightness of the 851N display backlight. There are three brightness
levels; off, dim, bright and an option to switch-off the backlight.
When the display is set to OFF, nothing will be displayed onscreen until a selection
is made via the front panel or remote control. The display will then re-activate
allowing you to browse the menu and make your selection. The display will then
automatically switch back off after a few seconds if no further selections are made.
Device name
This menu allows the setting of the declared UPnP Client name for your 851N.
This is the name other UPnP devices (such as control points and remote apps etc.)
will display when they see the 851N.
The default name will be ‘851N’ but can be changed to any name you can easily
recall such as ‘Dads 851N’ or ‘Kitchen’ etc.
Audio
This menu contains a setup configuration as shown below.

USB Audio Class
Digital Pre-amp mode, when enabled, allows volume adjustment to be performed
within the up-sampling Digital Signal Processor (DSP) before being converted to an
analogue audio signal for connection to a power amp.
Normally, the output of 851N (and most other source components) is output at
"full-scale" (i.e. maximum volume). This signal is then fed into a pre-amp which is
used to control the volume of all audio sources connected to it.
To enable Digital Pre-Amp mode it must first be activated within the setup menus.
Go to "Settings -> Audio -> Digital Pre-amp Mode" and set to "On". 851N will then
respond to the vol+ and vol- buttons on the remote control at any time.
It is also possible to adjust the volume using the rotary controller knob on the front
of the unit.
Whenever the 851N is showing its ‘Now playing’ screen turning the rotary controller
knob will adjust the volume. Pressing back or home etc. to access the menu system
allows the use of the rotary controller for menu browsing. If you are in a menu and
need to adjust the volume immediately simply press the ‘
i
’ button to go straight to
‘Now playing’ and then use the rotary controller.
The last used volume setting is memorised when the unit powered off.
USB audio class
USB Class options enable 851N compatibility with both USB Audio 1.0 and USB
Audio 2.0 interface formats. The default setting is USB Audio 1.0 which will work
driverlessly with most operating systems for 16-24 bit content at 32-96kHz. Note
USB Audio 2.0 requires a driver to be loaded for Windows. Without this selecting
USB Audio 2.0 will normally give no output. See earlier section on USB Audio for
advanced users.
System remote control
There are four options:
Standard 8-Series – is the default and works with the 851N remote control when
the handset is in default mode.
Alternate 8-Series – gives a secondary code set in cases where the 851N remote
codes are found to clash with another remote handset.
If Alternate 8-Series is selected on the 851N then the remote handset must also be
set to Alternate remote codes as well as follows:
Press and hold down the DAC/SM power button whilst inserting the batteries to
switch to Alternate 8-Series control codes.
By inserting the batteries without the DAC/SM power button held down will default
to Standard 8-Series codes.
CX-Series – choose this option to enable the system remote control from the CX
range to control the 851N.
No remote control – this will disable the ability of any of the above remote controls
to operate the 851N.
