It describes what you should find when you unpack the stereo power amplifier, how you should connect it to your other audio equipment, and the siting constraints. You should not make any connections to the stereo power amplifier or to any other component in your system whilst the AC power supply is connected and switched on. Unpacking The 556 Stereo Power Amplifier comes in a box containing the following components: r 556 Stereo Power Amplifier. During normal operation the heatsinks, ie the fins at each end of You are advised to retain the packing in case you need to transport the unit. Setting up the stereo power amplifier If you are not going to use the stereo power amplifier for a period of several days you should switch the unit completely off, at the back panel, and disconnect it from the AC power supply. To position the stereo power amplifier the case, may become quite hot. The stereo power amplifier should therefore be positioned to allow a free flow of air around the fins. Before connecting power Do not place the stereo power amplifier: Before you begin installation you should ensure that your stereo Power 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. Once set up, the stereo power amplifier can be left switched on as it consumes negligible power when not in use. r Stacked with any other audio products, as the heat it generates may damage the other products. 8 Connecting the stereo power amplifier Back panel Input (R) Input (L) INPUT + ­ OFF ­ + INPUT + ­ ON ­ + Setting up the stereo power amplifier Outputs (+) Outputs (-) Outputs (-) Outputs (+) Outputs The output terminals should be connected to loudspeakers of 4 to 15, using either banana plug or bare wire connections. Each channel of the 556 Stereo Power Amplifier provides twin outputs for bi-wiring. On speakers that provide separate connections to the bass/mid and tweeter units this allows the units to be connected independently to the stereo power amplifier, for optimum sound quality. Alternatively, for loudspeakers providing a single pair of inputs, either of the output terminals can be used. 9 To connect to a conventional preamplifier q Connect the sockets marked INPUT on the back panel of the stereo power amplifier to the outputs from your preamplifier. [. . . ] Disconnect the power cord before cleaning the unit. Note: Do not use abrasive cleaners on any part of the stereo power amplifier. To clean the audio connections The audio sockets on the back of the stereo power amplifier are gold-plated and need no cleaning if gold-plated phono plugs are used. Otherwise, it is recommended that you unplug and reconnect the plugs at least once a year. A proprietary contact cleaner can be used to some advantage. To change the mains fuse Setting up the stereo power amplifier Fuse Spare To clean the case q Use a slightly damp cloth. [. . . ]
