[QUOTE="canofan, post: 511054, member: 259756"] A quattro allows you to use individual line amplifiers that are powered by the multiswitch instead of by the receiver. Those installations that need a line amplifier are better served by a quattro. Besides, as the switching of the quad switches the local oscillator to the correct polarity it also varies the supply voltage to the LNB port. With the quattro the voltage on the LNB port is not varied and the polarity/22khz emitted by the receiver serve only as a signal to the multiswitch with no current. Everytime the receiver is turned off the Quad goes dead and is reactivated when turning the receiver on again. The multiswitch being on continuously does not subject the LNB to these changes of state. This implies longer life for the LNB and the receiver. [/QUOTE]
