User manual AUDIO ANALOGUE PUCCINI SPECIAL EDITION

[. . . ] While operating, it's quite normal that the amplifier warms up. Please allow at least 2" clearance all around the cabinet in order to ensure adequate ventilation. Best results can be obtained by resting the unit on a hard, flat surface. Before connecting the amplifier to the mains socket, please check that the voltage setting, indicated on the rear panel near the IEC inlet, corresponds to your local AC voltage. [. . . ] Be extremely careful not to short-circuit the speaker outputs: this could cause the internal 3. 15A fast fuses (2 per channel) to blow , or even damage the circuitry. Do not connect speakers with impedance lower than 4 L'amplificatore prevede due coppie di morsetti dorati per il collegamento dei diffusori, in grado di accettare filo nudo oppure dei capicorda a forcella. Non collegare diffusori con impedenza inferiore a4 "Bi-wiring" stands for a particular way of connecting speakers to an amplifier: one cable pair is connected from the "main" outputs to the speaker's low frequency section ("woofer"), whereas the other cable pair is connected from the "bi-wiring" outputs to the speaker's mid-high frequency section ("mid-range / tweeter"). One advantage of this type of connection is the possibility of choosing different types of cable for low frequencies and mid-high frequencies. With two separate sets of cables (with speakers that allow this type of connection), the final sound quality can be further enhanced. The Puccini Special Edition facilitates this type of connection by means of double speaker connectors for each channel. Once all connections have been correctly made (please check twice!), make sure the volume control is turned completely anticlockwise then turn the unit on by pressing the power switch near the IEC socket on the rear panel. On the front panel, the power indicator will glow red to indicate that the unit is in the power-up standby. After about one second, the unit becomes operating. When the volume know is turned clockwise to raise the volume, the power indicator becomes green, to indicate thet the unit is operating and out of standby mode. As described in the "Controls" section, the volume control incorporates an automatic standby circuit that is activated when the knob is turned completely counterclockwise, allowing the amplifier to be left powered-up. This is useful because, while already musical after power-up, the amplifier reaches its best sonic performance at the optimal working temperature. Using the standby feature, the amplifier may be left running between one listening session and the next, thus giving its best right from the first few notes. We advise you not to leave the unit always switched on: this could increase the risk of damage arising from mains survoltages (lightning). If, after power-up, the power indicator starts blinking red, then a fault in the amplifier circuit or a short-circuit on the speaker outputs are present. Turn the amplifier off, carefully check for wrong cable connections on the speakers outputs causing shortcircuits and turn the amplifier on again. If the power indicator still blinks, turn the amplifier off and contact your Audio Analogue dealer for servicing. Also, if the power indicator remains turned off after powering the unit, turn the amplifier off and contact your Audio Analogue dealer. So, during normal listening, the protection circuit is inactive. Light current overloads are managed reducing the current output, while severe overloads cause the protection to completely isolate the amplifier, entering the "emergency" mode that can only be reset by turning the amplifier off. [. . . ] unplug the unit from mains if unused for long periods. Always replace fuses with same type - Bypassing fuses may represent a safety hazard. Cleaning the unit - Always off before cleaning; wipe gently with a soft, dry cloth. Never use any solvents or alcohol-based cleaning liquids. [. . . ]
