[. . . ] Before you proceed, find the serial number which is located on the rear panel of the unit and note it here for future reference or in case of theft in shipment. MAKING CONNECTIONS: Before making any signal or speaker connection, make sure your power amplifier is turned off and unplugged. When making connections, make sure there is no strain or tension on input leads or speaker wires that could cause them to pull loose in the future. Input Connections: Use the RCA jacks for the R and L channels. Make sure these are consistent with R and L outputs from your preamplifier. Looping Jacks PLACEMENT: Keep your Sonamp out of direct sunlight and away from windows where rain may enter. It should be placed away from heat sources such as hot air ducts or radiators; do not place the unit directly on a pile carpet that could interfere with air flow into its bottom vent opening. If you stack your components, it is better to place the Sonamp above or alongside your other components; when driven hard, the unit itself may create a little heat and disturb components stacked on top of it. If it is inside a cabinet, allow ample ventilation. Very sensitive low level sources might pick up some hum radiating from its enormous power supply. Your Sonamp provides a pair of RCA output jacks which duplicate the input signal. These facilitate connection of additional power amplifiers from a single source component. With only a single input connector pair you can link or "loop" amplifiers without messy Y-cord adapters. Speaker Connections You may use either bare wire or banana plugs with the Sonamp "5-way" terminals. If you use bare wire without spade lugs or plugs, make sure you strip only enough wire (1/2") to fit into the slot in the terminal. Before inserting the wire, twist all its strands tightly to prevent strays that could cause a short circuit between + and - terminals!Use a small flat-bladed screwdriver to move the recessed switch. Now the Sonamp power switch will function conventionally and the Sonamp will turn on and off from a switched AC outlet on your preamp or other source component. AC Line cord You can plug this into a wall socket or an AC outlet on your preamplifier. Make sure your preamp outlet rating is equal to or greater than the Sonamp's power consumption rating. If you do not plan to use the automatic turn on/off feature, you will probably want to use a switched AC outlet that is turned on and off by your preamp's power button. If you choose to use the Auto Turn on/off feature, you must leave the Sonamp plugged into an unswitched AC outlet that is always "live"even when the preamp is turned off. If you are installing the Sonamp in a remote zone, you may plug it into the closest AC wall socket that is always "live". Caution: To prevent electric shock, match wide blade of plug to wide slot, fully insert. Attention: Pour evitar les chocs electriques, introduire la lame la plus large de la fiche dans la borne correspondante de la prise et pousser jusqu'au fond. Use only a heavy-duty extension cord, if required, to avoid starving the amplifier of all current necessary for full power operation. Level Controls Front panel level controls are recessed for adjustment by screwdriver only. This prevents accidental tampering with levels. Use level controls to adjust the left-right channel balance to match the listening area to speaker placement in the zone powered by the Sonamp.
