[QUOTE="tesla, post: 745456, member: 218346"] I don't know this Q2 but it's doesn't seem to be something super, advanced, hi-tech. Each input of the multiswitch sends the appropriate voltage and the 22kHz tone (if necessary) to the LNB ports, so simple. This feature is available to the 4 Sat IF amplifier SBK 5503 from Spaun. This kind of switch is necessary. Anyone interested in connecting a multiswitch to Quad/Octo should search all the companies: spaun, Televes, Ikusi, Johanson, Wisi etc etc This is very strange "issue". Perhaps it would be necessary to measure the actual value of the voltage and the level of the 22kHz (this measurement requires an oscilloscope). The 13V are not supposed to be 13,0000V, a small deviation is acceptable. The only i can think of is the power consumption (receiver's DC out at the LNB connector), the milliamperes that the LNB requires.
