The power supply unit of the PowerGenius XXL Twin power amplifier is permanently installed, it processes a single-phase mains voltage of 90 to 250V AC and is therefore ideally equipped for international operation, for example with DX peditions.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">Depending on the requirements and layout of the radio station, this amplifier can be operated either as\u00a0two completely independent amplifiers\u00a0(1500+W each) or as a\u00a0single amplifier with\u00a0an output of 3500W (combinied) in SO2R configuration. The TWIN topology offers the user incredible flexibility.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">Features of the XXL TWIN include the MEffA algorithm and the first TWIN topology to combine two independent amplifier modules in one.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">The MEffA system (Maximum Efficiency Algorithm) controls the efficiency depending on the output power. MEffA is a unique algorithm that adjusts the DC voltage level in the PA to the envelope of the exciting RF to achieve the highest efficiency.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">The PA is of course prepared for remote-controlled operation and equipped for the connection of one or two transceivers (SO2R contest operation). A variety of connections are available for this purpose &#8211; from the band data connection to Icom CI-V and the serial CAT interface through to an Ethernet connection. FlexRadio transceivers in particular can be connected with minimal effort (nice and simple), but of course you can also use any other transceiver with the PA.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">Operation with the Power Genius XXL Twin is further simplified by protective mechanisms that protect the power amplifier and the transceiver. The temperature is monitored, a warning is issued if the SWR is too high, the power is reduced and much more. A color LC display provides information about the current power and operating status. The only control element is the standby\/operate button on the front, everything else is fully automatic. Nice and simple.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">Extremely quiet cooling<\/div>\n<div style=\"text-align: justify;\">A good amplifier needs a good cooling system. The use of oversized fans, which are controlled by software and controlled depending on the temperature, reduces the fan noise to a minimum.<\/div>\n<\/div>\n<\/div>\n<div><\/div>\n<div>\n<table id=\"product-attribute-specs-table\" class=\"data table additional-attributes\" style=\"width: 42.0083%;\">\n<tbody>\n<tr>\n<th class=\"col label\" style=\"text-align: left; width: 32.646%;\" scope=\"row\">Product Name<\/th>\n<td class=\"col data\" style=\"width: 70.2749%;\" data-th=\"Product Name\">Power Genius XXL Twin<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" style=\"text-align: left; width: 32.646%;\" scope=\"row\">Supported Bands<\/th>\n<td class=\"col data\" style=\"width: 70.2749%;\" data-th=\"Supported Bands\">160m, 80m, 60m, 40m, 30m, 20m, 17m, 15m, 12m, 10m, 6m<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" style=\"text-align: left; width: 32.646%;\" scope=\"row\">Remote Control capabilities<\/th>\n<td class=\"col data\" style=\"width: 70.2749%;\" data-th=\"Remote Control capabilities\">Yes<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" style=\"text-align: left; width: 32.646%;\" scope=\"row\">Temperature Range<\/th>\n<td class=\"col data\" style=\"width: 70.2749%;\" data-th=\"Temperature Range\">-25\u00b0C ~ +40\u00b0C<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" style=\"text-align: left; width: 32.646%;\" scope=\"row\">Brand<\/th>\n<td class=\"col data\" style=\"width: 70.2749%;\" data-th=\"Brand\">4O3A<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" style=\"text-align: left; width: 32.646%;\" scope=\"row\">Weight<\/th>\n<td class=\"col data\" style=\"width: 70.2749%;\" data-th=\"Weight\">29 kg<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" style=\"text-align: left; width: 32.646%;\" scope=\"row\">Max.
