It keeps the original's design, a fanless linear circuit with an internal QRT module that smooths the DC output and removes noise artifacts from the line, and adds a second top-grade transformer so that the variable outputs can deliver far more current. Nordost rates output A at up to 114 W continuous at 19 V and output B at 72 W at 24 V, with short-term peaks of 160 W and 100 W, which brings music servers, larger streamers and DC-powered DACs within reach of one supply.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px\"\u003eThe back panel carries four 5 V outputs for QPOINT Resonance Synchronizers and two variable outputs: A selects 9 or 12 V and B selects 12, 19 or 24 V, each by a switch, with a blue LED on the front once the unit is powered. All six outputs can be used at once within the published power limits. The unit is factory-set for 115 V and protected by a 3.15 A time-lag ceramic fuse, with a spare in the fuse holder.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 20px\"\u003eChoose the MKII when the component you are powering draws more than the original QSOURCE's 66 W variable output, when you want to run a server and a switch from one supply, or simply as the reference choice in a system built on QNET7, QBASE Reference and QKORE. We specify the DC cables and voltage settings for your components before it ships.\u003c\/p\u003e\n\u003ch3 style=\"margin:0 0 8px;font-size:16px\"\u003eKey technologies\u003c\/h3\u003e\n\u003cul
