This manual.

You are advised to retain the packing in case you need to transport the unit.

Before connecting power

Before installation you should ensure that your integrated amplifier is set to the correct voltage for your local AC supply. If it is not, do not try to install the unit, and contact your dealer.

Do not make connections, or insert or remove plugs, while the unit is connected to the supply and switched on, as the transients generated could damage the loudspeakers.

Setting up the integrated amplifier

To position the integrated amplifier

During normal operation the heatsinks, ie the fins at each end of the case, may become quite hot. The integrated amplifier should therefore be positioned to allow a free flow of air around the fins. Do not place the integrated amplifier:

In direct sunlight.

Near heat sources, eg a radiator.

Stacked with any other audio products, as the heat it generates may damage the other products.
