S1-S5
These inputs are suitable for any ‘line level’ source equipment such as
BD/DVD players, DAB or FM/AM tuners, CD players, Netwok Players,
iPod docks, MP3 players, etc.
Note: These inputs are for analogue audio signals only. They should not
be connected to the digital output of a CD player or any other digital
device.
Connecting a turntable
If it is desired to connect a turntable without a built-in phono stage, an
external phono stage such as our 551P or 651P models should be used.
Contact your Cambridge Audio dealer for more details.
Note:
A very few turntables have built-in phono stages, in which case it is
not necessary to use a separate phono stage amplifier. If you’re unsure,
please consult your turntable user manual.

Record Out
These output sockets can be connected to a tape deck or to the analogue
Record In sockets on a MiniDisc or CD recorder.
3
Loudspeaker terminals
Two sets of loudspeaker terminals are available, A (main loudspeaker
terminals, left terminals) and B (secondary switchable loudspeaker
terminals, right terminals). Connect the wires from your left channel
loudspeaker to the LEFT positive and negative terminals, and the wires
from the right channel loudspeaker to the RIGHT positive and negative
terminals. In each case, the red terminals are the positive outputs and
the black terminals are the negative outputs.
Care should be taken to ensure no stray strands of wire are shorting
speaker outputs together. Please ensure that the loudspeaker terminals
have been tightened adequately to provide a good electrical connection.
It is possible for the sound quality to be affected if the screw terminals
are loose.
The use of A and B speakers affords you an easy and inexpensive way
to create a simple multi-room system.
Note:
When using two pairs of speakers, use speakers with a nominal
impedance of 8ohms.

Mains voltage selector switch
Switches the mains voltage between 115V and 220-230V. For use by
installer/dealer only.
5
AC power socket
Once you have completed all connections to the amplifier, plug the AC
power cable into an appropriate mains socket and turn the unit on. Your
amplifier is now ready for use.
6
USB interface
A USB B type socket is fitted to the 351A to enable the playback of
audio from a personal computer running either Microsoft Windows or
Apple Mac OS X operating systems. Some distributions of Linux are also
suitable.
Note:
Always use a certified cable for USB Audio preferably one that
displays an official mark. USB cable connections longer than 3m may
result in inconsistent audio performance.

Always turn the Volume to minimum, switch to another
input or turn the 351A off before plugging/unplugging
cables to the USB input or whilst booting up/shutting
down your PC/Mac.
