Set-up
Installation
This product relies on free convection of air along the sides and top for cooling. Avoid placing
magazines, books or other objects on top of the product as this acts as thermal insulation.
Installation inside a cupboard is permissible provided at least 30cm (12”) of free space above the
product and 10cm (4”) around the sides is respected. Operation in closer qua
rters requires some
provision of forced convection (fan) to be installed inside the cupboard.
Connections
CAUTION: Whenever you are plugging or unplugging cables, make sure that the power amp is off.
Failure to take this precaution may result in pops or bangs in the loudspeaker. Use properly
shielded interconnects with reliable connectors.
AC power input
Connect a power cord with IEC C13 plug on amplifier side to the AC input socket (1) on the rear
panel. Do not connect the power cord until all the audio input and output connections have been
made.
It is usually best to plug the product directly into a wall outlet. Avoid the use of extension cords. A
heavy-duty multi-tap power outlet strip may be used if it and the wall outlet are rated to handle the
total current demanded by the components connected to it.
If you are going to be away from home for an extended period of time such as a month-long
vacation, it is a sensible precaution to unplug electronic equipment. Do the same as a precautionary
measure during thunderstorms. No amount of surge protection or mains filtering will save your
equipment from a lightning strike in the backyard.
Input connection
The inputs (4) are of XLR or RCA type. In the case when your preamp/DAC would be equipped with
both XLR and RCA connectors, we recommend using the XLR connection. Depending of the one
chosen, set the toggle switch to the corresponding position.
Output connection
Connect the speaker negative input to the amplifier black binding.
Connect the speaker positive input to the amplifier black and red binding.
