41. IMPORTANT NOTECongratulations! You are the owner of a carefully designed and manufactured equipment. Wethank you for trusting on us and choosing our amplifier eGPA.In order to obtain maximum operativity and perfect functioning order, it is most important to carefullyread all considerations taken into account in this manual before connecting this amplifier.We recommend our authorised Technical Services if any maintenance task should be needed sothat optimum operation shall be achieved.1.1. PrecautionsThe amplifier should have an earth connection in good conditions (earth resistance, Rg=30Ω orless). The environment must be dry and dustless. Do not expose the unit to rain or water splashes, anddo not place liquid containers or incandescent objects like candles on top of the unit. Do not obstruct theventilation shafts with any kind of material. In case there is some type of intervention and/or connection-disconnection of the amplifier, it is most important to previously disconnect the mains power supply.Do not manipulate the output terminals to the loudspeakers when the amplifier is switched on,there are voltages up to 400Vpp. The output cabling should be connected by a qualifiedtechnician. Otherwise only use pre-made flexible cables. There are no user serviceable partsinside the amplifier.Failure to do so may result in malfunction of the device and may even damage the device:1. Avoid turning on the device without speakers connected to its outputs and withoutsetting the volume / gain controls to the minimum.2. Always use shielded cables to make the connections between devices.2.
