If it is desired to connect external power amplifiers, use Phono/RCA leads
connected to the 7.1 Preamp Outputs on the rear panel.
For 5.1/7.1 use set the ‘Preamp Out’ setting in the ‘Output Setup’ OSD menu
to 'Pre Out' rather than 'Normal'. This mutes all the internal power amplifiers
as they are not being used.
Alternatively the 551R features an External 2-Channel mode. This allows the
551R to reproduce all the surround channels of suitable source material
(Centre, Surrounds and Sub) whilst the Left and Right Front speakers are
driven by an external power amplifier or other amplifier capable of supporting
fixed level inputs (e.g. Cambridge Audio’s own 7/8 series amplifiers).
Set the ‘Preamp Out’ to ‘Ext 2 Ch’ in the OSD to mute the 551R’s own front
left and right amplifier outputs only:

Front input connections
The front panel Video 3/MP3 input is for temporary connections to video
games consoles etc. Remove the cap to access the Video 3 inputs and
connect to a video game console or video camera’s outputs using stereo
phono cables (RCA-RCA) and a Composite video cable. Alternatively, use the
3.5mm mini-jack MP3 socket for the headphone/line outputs of portable
MP3 players.
FM aerial
Connect an aerial to the FM 75 ohm socket (a simple wire aerial is supplied
only for temporary use). Extend the lead and move the aerial around until you
get the best reception. For continued use, we strongly recommended using a
75ohm outdoor FM aerial.
AM loop aerial
Connect each end of the single length antenna to the antenna terminals.
Place the antenna as far from the main system as possible to prevent
unwanted noise and to obtain optimum reception. If the AM loop aerial
provided does not receive sufficient reception, it may be necessary to use an
outdoor AM aerial.
