The DEMIDOFF uses the finest version of the Mirror-AmpTM pre-amp section. It consist of a gain stage made with a proprietary special cascode differential amplifier employing a mirror current. This configuration produces a super-linear signal, virtually eliminating distortion. [. . . ] It ought therefore to be protected from any eventual variations in temperature and humidity. Avoid using in the vicinity of radiators or other strong heat sources, electrical and electronic motors, switched on mobile phones etc. The location in proximity of other audio components is not theoretically critical, but you should nevertheless pay attention to this. If it should have to be moved after the installation, certain readjustments may need to be made. In any case, take care to switch OFF and detach the AC power chord from the AC wall plug the DEMIDOFF integrated amplifier every time you need to move it. The high weight of the amplifier is not suitable to be positioned on any other components of the hi-fi system. Operating Conditions Once it has been correctly mounted and wired with its AC power Chord, and once the unit is be en wired to a line input of the amplifier with a proper interconnect cable, your DEMIDOFF integrated amplifier is ready for use. TO PREVENT HIGH QUALITY SOUND PERFORMANCES THE DEMIDOFF DOES NOT HAVE ANY OUTPUT PROTECTION. SHORT CIRCUIT OR WRONG SPEAKERS (BELOW THAN 4 OHMS) MATCHING IRREMEDIABLY DAMAGE THE AMPLIFIER OUTPUT BOARDS AND THE OTHER UNITS CONNECTED TO IT. THE UNIT IS PROVIDED WITH THERMAL SWITCHES PUT ON BOTH CHANNELS HEAT SINKS AND POWER TRANSFORMERS. BEFORE THE UNIT REACHES A DANGEROUS TEMPERATURES IT TURNS OFF AUTOMATICALLY UNTIL IT WILL COOL DOWN TO A REGULAR OPERATING TEMPERATURE LEVEL. IF THE UNIT TURNS OFF DURING PLAYING SWITCH IT OFF AND WAIT 30/60 MINUTES. SWITCH ON AGAIN A CHECK EVERYTHING IS BACK NORMAL BEFORE CALLING ASSISTANCE FO R SERVICE.

The remote volume control with its proper electronic board and power transformer (to avoid any kind of interferences on signal path) works directly on a DC motors positioned on the back of the pontentiometer to avoid the use of electronic controllers can reduce sound quality. Becarefull during the remote use: the remote moves the volume very slowly when the triggers UP or DOWN are mainteined pushed. Vu-Meters The DEMIDOFF has 2 separately powered Vu-Meters. The Vu -Meters are fluorescent lighted both with its proper internal power transformer. Both are connected to a specific transformer to decouple them from the D. S. electronic boards transformers having the best possible decoupling.
