[. . . ] Not respecting the instructions contained in this manual will invalidate the guarantee terms and conditions. NECESSARY PRECAUTIONS FOR SAFETY AND MAINTENANCE ATTENTION: Read the following instructions and precaution carefully and completely before. operating or manteining your Audio Analogue MAESTRO DUECENTO SE integrated amplifier. It's mandatory to comply with the following regulations to avoid any hazard: Always disconnect your entire system from AC mains before connecting or disconnecting any cables. [. . . ] A great deal of effort went into the design and construction of the MAESTRO DUECENTO SE power amplifier. No capacitors in the signal path and only double-side metallized polypropylene film capacitor in the critical points. The internal stages are DC coupled and the offset is reduced by means of an integrating amplifiers. The protection and control sections are galvanically insulated from the analog sections to minimize the digital noise. The voltage of both channel is measured by means of optocoupler to avoid any ground loop. the DC offset on the output (loudspeakers) is also monitored by means of optocouplers. The protections are realized with a PLD (Programmable Logic Device); it's faster and more reliable compared to a microcontroller. STATUS LED This LED is "low intensity red" when the left amplifier is off. It's "bright red" when the left power amplifier is turning on. It's green when the left power amplifier is operating and "blinking red" is there is a problem. sTATUS LED This LED is "low intensity red" when the right amplifier is off. It's "bright red" when the right power amplifier is turning on. It's green when the right power amplifier is operating and "blinking red" is there is a problem. LEFT BALANCED INPUT: Balanced line left input RIGHT BALANCED INPUT: Balanced line right input SWITCH: Select balanced or unbalanced inputs. FUSE: If necessary, replace it with another of the same kind (see back panel label). If one of the items listed above is missing, please contact your Audio Analogue retailer. After extracting the smallest items from the package, pull out the unit carefully. Where to place the MAESTRO DUECENTO power amplifier MAESTRO DUECENTO SE is a high power unit. After some hours of high volume operation the unit temperature can raise up to 45-50°C, be careful!In particular, you should leave at least 5 cm around and above the unit and avoid placing it close to heat sources (radiators, heaters, amplifiers, television sets). Plugging and connecting Before connecting the MAESTRO DUECENTO SE power amplifier to the preamplifier, please be sure that they're all unplugged from wall outlets. First of all, connect the preamplifier to the MAESTRO DUECENTO SE inputs you want to use, selecting balanced or unbalanced mode before plugging the connectors.
