Connections

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.

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.
