When designing our amplifiers we have tried to include features that
allow you to connect your system in various ways. The inclusion of
features such as Pre-Out and Speaker B connections mean that you
can flexibly configure your system depending on your requirements.
Basic connections
The diagram below shows the basic connection of your amplifier to a
CD player and a pair of loudspeakers.
Note: If using Input 1 (Unbalanced), the Input 1 switch must be in the
‘Unbalanced’ position.
Tape connections
The diagram below shows how to connect the amplifier to a tape
recorder or other source with a record and monitor connection.
Please note that either of the tape loop outputs can be used (as they
are both the same signal in parallel).

Speaker B connections
The Speaker B connections on the back of the amplifier allow for a
second set of speakers to be used (i.e. speakers located in another
room). The Speaker A/B button on the front panel allows this second
set of speakers to be switched on and off.
Note: When using two pairs of speakers, use speakers with a nominal
impedance of between 6-8 ohms each minimum.
Preamp Out connections
The Preamp Out sockets are for connecting to the input sockets of a
power amplifier or active subwoofer. The diagram below shows how to
connect the amplifier to an active subwoofer via the Line In inputs on
the subwoofer.
