Loudspeaker terminals
Two sets of loudspeaker terminals are available,
A
(main loudspeaker
terminals, top row) and
B
(secondary switchable loudspeaker terminals,
bottom row). 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 terminal is the positive output and the black
terminal is the negative output.
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 8 ohms.

Digital inputs
Toslink and S/P DIF co-axial digital inputs.
Note:
To obtain the best results from your system we recommend using only high
quality Cambridge Audio interconnects. This will ensure that you hear your system
as we designed it. Please ask you dealer for details.
2
Audio inputs
These inputs are suitable for any ‘line level’ source equipment such as the
audio outputs of CD players, BD/DVD players, etc.
3
Phono input
This input has a built in phono stage. Record players fitted with Phono
Cartridges of the Moving Magnet (MM) or
high output
Moving Coil (MC)
type (between 2-6mV output and 30-50k load impedance) can be used.
Low output Moving Coil types (
impedance) cannot be directly connected and will require a matching
transformer or head amp. Please consult your dealer for details. The
‘ground’ terminals on both the record player and the SR20 should be
connected (where possible) with a ground wire for lowest noise/hum
pickup.
4
Rec Out
Connect to the recording input of a tape deck, CD recorder input, etc.
5
Sub-Out
For optional connection to the input socket of an active subwoofer if
desired.
6
AM/FM antenna
Tuner aerial connections for picking up radio signals. Refer to the
‘Connections’ section of this manual. For permanent use, outdoor AM/FM
aerials are highly recommended.
7
Service port
For servicing use only. Do not connect anything here as it may result in
damage.
